Basics of SELinux and Its Importance

Security-Enhanced Linux (SELinux) is a crucial component of Linux security, providing a robust mechanism for enforcing security policies that control access to resources on a system. In this blog post, we will delve into the basics of SELinux, its significance, and why every Linux administrator should understand and utilize it.

What is SELinux?

SELinux is a Linux kernel security module that provides a mechanism for supporting access control security policies. It was developed by the National Security Agency (NSA) as a series of patches to the Linux kernel and then integrated into many Linux distributions, including Red Hat Enterprise Linux (RHEL), CentOS, and Fedora.

How SELinux Works

SELinux uses a concept called Mandatory Access Control (MAC) which differs from the traditional Discretionary Access Control (DAC) used by standard Linux. In DAC, the owner of a resource determines the access control; however, in MAC, the system enforces policies that dictate the access rights, independent of the owners' preferences.

Key Components of SELinux:

Security Policies: These are sets of rules that define what actions subjects (users, processes) can perform on objects (files, directories, ports). Policies can be very granular, specifying permissions for individual actions.

Contexts: SELinux uses contexts to apply policies. Every file, process, and resource in the system has an associated context, typically defined as user:role:type.

Modes: SELinux operates in three modes:

Enforcing: SELinux policies are enforced, and violations are logged.

Permissive: SELinux policies are not enforced, but violations are logged. This is useful for debugging.

Disabled: SELinux is turned off.

Importance of SELinux

1. Enhanced Security

SELinux adds a layer of security that helps mitigate the impact of system vulnerabilities. By enforcing strict access controls, SELinux can prevent compromised applications or users from accessing sensitive data or escalating privileges.

2. Confined Domains

SELinux confines processes to specific domains, limiting their ability to interact with other processes and system resources. This containment reduces the risk of widespread damage if a process is compromised.

3. Granular Control

SELinux allows for detailed and fine-grained control over system access. Administrators can define policies that specify exactly which resources a process can access, down to the level of individual files and actions.

4. Compliance and Standards

Many industries require compliance with strict security standards and regulations. SELinux helps meet these requirements by providing robust access control mechanisms, ensuring that systems adhere to best practices and regulatory guidelines.

Basic SELinux Commands

To effectively manage SELinux, you need to be familiar with a few basic commands:

Check SELinux Status: sestatus

Change SELinux Mode: setenforce [enforcing|permissive]

View SELinux Contexts: ls -Z ps -eZ

Manage Policies: semanage fcontext -l restorecon -Rv /path/to/directory

Enabling and Configuring SELinux

Enabling SELinux

SELinux is typically enabled by default in most major distributions like RHEL, CentOS, and Fedora. However, if you need to enable it, you can do so by editing the /etc/selinux/config file:

SELINUX=enforcing

After making this change, reboot your system to apply it.

Configuring SELinux Policies

Configuring SELinux policies involves defining and applying the rules that control access. Tools like audit2allow can help generate custom policies based on logged denial messages, making it easier to fine-tune your security settings.

Troubleshooting SELinux Issues

When SELinux blocks legitimate activities, you can troubleshoot by:

Checking Logs: SELinux logs are stored in /var/log/audit/audit.log. Reviewing these logs can help identify what was denied and why.

Permissive Mode: Temporarily setting SELinux to permissive mode can help diagnose issues without enforcing policies.

Creating Custom Policies: Use tools like audit2allow to create policies that allow necessary actions without compromising security.

Conclusion

SELinux is a powerful security feature that enhances the security posture of Linux systems. By understanding its basics and importance, administrators can leverage SELinux to enforce strict access controls, mitigate risks, and comply with regulatory requirements. While it may seem complex at first, the security benefits it provides make it an essential tool for any serious Linux administrator. Embrace SELinux, and take control of your system's security today!

Breaking it Down: The ABCs of Authentication and Authorization

Introduction

Progressing through the landscape of digital evolution, where enterprises embrace the era of robust cloud-based systems and fortify their online security, the symbiotic relationship of authentication and authorization emerges as a cornerstone. Despite their frequent interchangeability, these terms hold distinct meanings, serving pivotal roles within the realm of customer identity and access management (CIAM). Authentication, the digital verifier, rigorously confirms the user's identity, validating their legitimacy in the vast digital panorama.

Concurrently, authorization assumes the role of the access validator, scrutinizing and validating the user's access rights to ascertain if they possess the necessary privileges for specific functions. This strategic alliance between authentication and authorization is not a mere procedural protocol; it stands as a formidable defense against potential breaches and unauthorized access, fortifying the security defenses around sensitive data assets.

What is Authentication?

Authentication, the guardian of digital boundaries, stands as the process of confirming users' identities and validating their asserted personas. Tradition has often tied this process to passwords, where the alignment of the entered password with the associated username paves the way for authenticated access. Yet, the digital narrative is undergoing a transformation, and enterprises are navigating toward the landscape of passwordless authentication. This shift introduces modern techniques such as one-time passcodes (OTP) via SMS or email, single sign-on (SSO), multi-factor authentication (MFA), and biometrics, sculpting a new frontier of security that extends beyond the conventional boundaries of passwords.

What is Authorization?

Imagine the digital landscape as a grand stage, and at its core, the performance of authentication and authorization unfolds. After a user's identity is successfully authenticated, the spotlight shifts to the authorization phase, where access rights are meticulously defined. In a corporate setting, envision an employee who undergoes the thorough process of ID and password authentication, emerging as a verified user. As the narrative progresses to authorization, the employee is endowed with specific access rights to critical resources such as databases and funds, each access right a well-crafted note in the symphony of digital security.

Authentication vs Authorization: Understanding the Techniques

As the guardians of CIAM navigate the complex landscape of digital security, the distinction between authentication and authorization takes center stage. Visualize an organization allowing all employees access to workplace systems – this exemplifies authentication. However, the subsequent layer of authorization sifts through to identify those employees with the right to access secured data within those systems. The seamless integration of authentication and authorization, fortified with the right techniques, emerges as a formidable shield for organizations, ensuring security while optimizing access for enhanced productivity.

Conclusion

In the ever-evolving landscape of digital security, the implementation of centralized identity and access management solutions emerges as a pivotal strategy for organizations. With cloud-based CIAM solutions at the helm, authoritative user identities are meticulously verified, and privileges and rights are seamlessly automated based on predefined roles. What makes these solutions indispensable is their commitment to operational efficiency. The elimination of manual permission definition not only fortifies security but also yields tangible benefits such as time savings, reduced backlogs, and an enhanced user experience. As organizations embrace these solutions, they not only bolster their security posture but also usher in an era of streamlined authentication and authorization.

The Benefits Of Using An Efficient Access Control System

Security is a primary concern for businesses of all sizes, especially regarding safeguarding resources, confidential information, and employees. Access control systems ranging from traditional keycards to biometric solutions provide a multitude of advantages for organizations and residential properties and also provide a reliable and efficient security solution by permitting or preventing access to particular areas within a building or premises. They not only enhance security but also offer convenience and flexibility in managing who enters and exits the premises.

What Is an Access Control System and How Does It Work?

An access control system is a technology based security system that regulates who can enter or exit a defined space, such as a building, room, or even a computer network. It allows authorized individuals to gain access while preventing unauthorized entry. Generally, access control systems consist of three functional elements which are the infrastructure, the administrative management dashboard, and finally the user-facing component which includes access cards, badges, and even smart phones. These elements function together to grant or deny access. When it comes to setting permissions, there are three significant types of access control systems are Mandatory Access Control (MAC), Discretionary Access Control (DAC), and Role Based Access Control (RBAC). Access control systems use various authentication methods to verify the identity of individuals seeking entry. Once the system authenticates a user, it checks their authorization level. Authorization specifies the areas or resources the user is allowed to access.

Benefits of Using an Efficient Access Control System:

Enhanced Security

Access control systems maintain security by regulating who can enter a building or specific areas within it. Users must authenticate themselves through methods like keycards, biometrics, PINs, or mobile apps. Access control systems substantially reduce the risk of unauthorized individuals gaining entry to secure areas.

Record-Keeping

Access control systems maintain detailed records of every access event, creating an audit trail. The system records various details about the access event, including the date and time of the event, the user’s identification or credentials used, the location or access point involved, and the result of the access attempt (whether access was granted or denied). These records are essential for security monitoring and compliance with regulations.

Convenience

Traditional keys can be lost, stolen, or duplicated. Door Access Control System in Dubai, UAE offer convenient, secure alternatives like keycards, biometric scans, or mobile apps. Administrators can easily add or remove users and adjust access permissions. This can be done remotely, which is especially convenient for organizations with multiple locations or off-site access points.

Remote Access

Modern access control systems often include remote monitoring and management capabilities. Remote access control provides flexibility and convenience for organizations with multiple access points or those that require the ability to manage access from off-site locations. It is particularly valuable for businesses that prioritize efficient security management and the ability to respond quickly to security events.

Integration

Access control systems often integrate with other security systems, such as video surveillance and intrusion detection. This integration enhances security management by providing a holistic view of security incidents.

Cost-Effective

Over time, access control systems can be more cost-effective than rekeying locks and managing physical keys. They also reduce the risk of security incidents, which can lead to substantial financial losses. Access control systems typically require an initial investment in hardware, software, and installation. The cost can vary widely based on the system’s complexity, the number of access points, and the type of authentication methods used (e.g., card readers, biometrics). Small-scale systems are generally more cost-effective than large-scale enterprise solutions.

Week 7 - 3 Types of Access Control: IT Security Models Explained

I found this website really helpful when trying to learn more about access controls. This website talks about three types of access controls Discretionary Access Control (DAC), Role-Based Access Control (RBAC), and Attribute-Based Access Control (ABAC) and the pros and cons about each one with examples of when they are most helpful. This helped me learn more about the topic for this week, and I thought it would good to share with everyone.

Understanding Access Control Systems

As businesses continue to adopt digital technology, the need for effective access control systems becomes increasingly important. Access control systems are the first line of defense in securing your organization’s sensitive data and assets. In this comprehensive guide, we will explore the fundamentals of access control systems, including the types, components, and best practices.

Types of Access Control Systems

There are three primary types of access control systems: Discretionary Access Control (DAC), Mandatory Access Control (MAC), and Role-Based Access Control (RBAC).

Discretionary Access Control (DAC) is the simplest type of access control system. In a DAC system, users have complete control over the resources they own, including who can access them. DAC is best suited for small organizations where the number of users is limited, and the security requirements are relatively low.

  Mandatory Access Control (MAC) is a more rigid type of access control system used in high-security environments. In MAC, access control is based on security labels assigned to resources and users. Users can only access resources with a label equal to or lower than their security clearance level.

  Role-Based Access Control (RBAC) is the most commonly used type of access control system in medium to large organizations. In RBAC, access control is based on job functions or roles within the organization. Users are assigned roles that define their level of access to resources.

Components of Access Control Systems

Access control systems consist of several components that work together to control access to resources. These components include:

Authentication: The process of verifying the identity of a user requesting access to a resource. Authentication can be achieved through various methods, including passwords, biometrics, or smart cards.

  Authorization: The process of granting or denying access to a resource based on a user’s identity and permissions.

  Access control policies: The rules that govern access control within an organization. These policies define who has access to what resources and under what conditions.

  Access control lists: A list of users or groups with specific access permissions to a resource.

  Access control models: The theoretical framework used to define the rules and policies of an access control system.

  Best Practices for Access Control Systems

Implementing an access control system requires careful planning and execution. Here are some best practices to keep in mind:

  Conduct a thorough risk assessment to identify potential security threats.

  Develop access control policies and procedures that align with your organization’s security goals. These policies should be reviewed regularly and updated as necessary to stay ahead of emerging security threats.

  Limit user privileges to only those required for their job function. This minimizes the risk of accidental or intentional misuse of resources.

  Regularly review access control lists to ensure they remain up-to-date. This ensures that users only have access to the resources they need and nothing more.

  Monitor access control logs to identify any suspicious activity. This allows you to quickly detect and respond to security breaches.

  Educate employees on the importance of access control and how to comply with access control policies. This helps to ensure that everyone in the organization understands their role in maintaining a secure environment.

  Advanced Access Control Techniques

In addition to the basic components and best practices of access control systems, there are also several advanced techniques that organizations can use to enhance security. These techniques include:

Two-Factor Authentication: This involves using two or more methods of authentication, such as a password and a fingerprint, to verify a user’s identity. This provides an extra layer of security beyond traditional password-based authentication.

  Biometric Access Control: This involves using a person’s unique physical characteristics, such as fingerprints, facial recognition, or iris scans, to authenticate their identity.

  Adaptive Access Control: This involves dynamically adjusting access control policies based on a user’s behavior and context. For example, if a user attempts to access a resource from an unusual location or device, the system may require additional authentication before granting access.

  Physical Access Control: This involves controlling access to physical spaces, such as buildings, rooms, or cabinets. Physical access control systems may use key cards, biometrics, or other methods to grant access to authorized personnel.

4 Types of access control systems

If you value security and who doesn’t install an access control system in your house or business is essential? It’s what allows authorized individuals to enter and keeps prohibited individuals out. Even within your own company, you might not want all your staff to have access to your main office or safe. Access control is the best approach to guarantee that only the individuals you trust may access sensitive sections of your property.

Different access control systems operate in various ways. Four different types of access control can be used to limit entry to your home or place of business. Each has advantages and disadvantages, so it's crucial to consider your particular security requirements and select the access control method that best suits them.

Discretionary Access Control (DAC)

With a discretionary access control system (DAC) the owner of the business can decide how many people have access to a specific location. Each access control point has a list of authorized users. Every time a keycard is swiped, a PIN is entered, or a fingerprint is scanned, the system checks the credential against the list and either grants or denies access based on the previously defined allowances.

DAC systems are thought to be the most adaptable and provide the greatest number of allowances compared to other types of access control. Because it’s the most flexible, it’s also not as secure as some other types, especially mandatory access control systems. Since one person has total control over the system, he or she might grant access to someone who shouldn’t have it. Discretionary access control systems are best for businesses that demand the greatest usability and flexibility.

Mandatory Access Control (MAC)

On the other hand of the spectrum, mandatory access control systems (MAC) are the most secure type of access control. Only owners and custodians have access to the systems. All the access control settings are preset by the system administrator and can’t be altered or removed without his or her permission.

Instead of creating an access list on each individual entry point like in a DAC system, a MAC system works by identifying all the users and granting them access to regions in accordance with the system’s programming. If you have 150 employees, you’re going to need 150 user permissions set up in the system.

Mandatory access control systems are the strictest and most secure type of access control, but they’re also the most rigid. In order to adjust permissions, the administrator has to reprogram the specific user’s access, not just the security lists at the entry point. Companies and government organizations that want the highest levels of security frequently utilize MAC systems.

Role-Based Access Control (RBAC)

Role-based access control (RBAC) is quickly becoming the most popular type of access control. Instead of assigning permissions to individual users like in a MAC system, an RBAC system operates by granting permissions to a certain job title. It reduces the amount of time needed to set up or modify user access.

For example, if you have 20 salespeople, two managers, and three accountants, you wouldn’t need to set up 25 different security profiles in the system. Only three would need to be made, one for each different job title. When an employee is promoted, all they need are credentials appropriate for the new position, and they are ready to go.

Rule-based Access Control

Not to be confused with the other “RBAC,” rule-based access control is commonly used as an add-on to the other types of access control. In addition to whatever type of access control you select, rule-based access control can modify the permissions in accordance with a particular set of rules that the administrator has established.

If your company closes at 5 p.m., there’s no need for anyone to have access to your main office, even managers, after closing. With rule-based access control, you can set a rule to deny access to everyone from 5 p.m. to 9 a.m. the next morning. There are rules for almost every situation.

Advantages Of Using Electronic Access Control Systems

There are three main categories of access control systems available in Singapore. The first, Discretionary Access Control System (DAC) is for those people working at places that are off-limits to all others. Employees in such positions are not allowed to have access cards or access card machines. The second is Role-Based Access Control System (PBAC) which is more suitable for offices that have high security requirements. Lastly, Mandatory Access Control is the most intrusive of all systems as it involves installing CCTV cameras at strategic places such as access control panel, office doors, etc.

DAC access control systems can be divided further into two sub-types. Discretionary access control systems require the employee to have a valid identification card while POS access control systems only require the employee to have a means of access. Both of these access control systems can be implemented using CCTV camera installed at strategic locations. CCTV footage can then be used to monitor areas where entry and exit of the employee is possible. CCTV can also be used to identify and supervise employees who have access to sensitive information and documents.

While the basic function of all access control systems is to restrict access of a restricted area, the features differ depending on the type of access control systems. For instance, a POS system includes a scanner that can scan a barcode and store the details in a database for use by sales personnel to determine prices. A CCTV system is able to capture the movement of people and determine the reason for their movement. This feature may be used to conduct random checks of premises. Surveillance systems monitor activities of people inside and outside of a building. Surveillance systems may include cameras, video monitors, access control card readers, radiofrequency identification (RFID) readers and night vision equipment.

There are instances when a surveillance system or access control system is used to prevent data breaches. The use of a security system in this case would be to detect any unusual movement of people and alert authorities if the breach occurs. For instance, an access control system could detect the movement of people through a PIR motion sensor device and trigger an alarm to notify security personnel. However, there are times when no alarm is triggered and the breach continues, thus exposing the employees to a higher risk of data breaches.

In most offices, electronic access control systems help to ensure that the workplace is safe from all threats, including the risk of terrorist activities. Electronic access control systems detect unlawful actions, record images of the work surroundings and alert management personnel. These systems protect companies from theft, vandalism and employee negligence. Electronic access control systems used in secured areas such as cash rooms and court rooms, along with CCTV, are effective tools to ensure the safety of business and minimize losses and protect company assets.

These systems play a vital role in increasing the efficiency and productivity of businesses by detecting illegal activity, monitoring personnel movements and deterring criminal activities. These systems also lower operational costs by reducing the number of data breaches and incidences of stolen or damaged documents. The systems have become an integral part of the business environment and have been used for more than a decade now. With rapid technological advancements and continuous research and development, these access control systems have become more advanced. This has made access control systems more practical and functional, making them easier to use, safer and more secure.

SELinux In Linux Server CentOS 7

Security-Enhanced Linux 

Security-Enhanced Linux as its name suggests it is security enhancement in Red Hat distribution. As we know in Linux the main benefit is that we can modify the kernel according to our needs and make our own flavor.  So SELinux is a kernel module(Centos) with more security by more security I mean access control security.

Before the introduction of SELinux which works on Mandatory access control(MAC), Discretionary access control was used.The DAC means the access control is based on the file owner and its permission. The root user has full access control with a DAC system.If the system is a normal workstation then using the DAC may be a good choice but if it a Red Hat-based Linux server the use of DAC is not a good practice. Giving all access control to one user is not advisable.

But after the MAC policy introduction by SELinux, there is an administratively prebuilt policy for access means if the DAC policy or its setting changes on the file, directory then SELinux policies are there to prevent the misuse of permission. Of course, SELinux gives flexibility to limit access between users for files, directory, and more. So, now comes the benefits of this hole thing we discussed, suppose you are running a Linux server(centos) with disable SELinux on it. if Your Linux server hosting many webpages and website, if any hacker can gain access through one of the vulnerability on these website vulnerabilities like

1. Web ports HTTP(80) and https(443)2. File transfer services FTP or proftpd3. Through ssh service4. Vulnerable plugin and theme installed on the website

After finding vulnerability first approach hackers is to put the shell inside the web server and gain the reverse shell to get the root access if we use old access policy like DAC then our hole server compromises and it makes easier for the hacker to do his job but with SELinux, there are some changes to protect our server. SELinux isolates the working of processes run by the local user to remove this type of chance of privilege escalation. The policies used by Mandatory access control are prebuilt we can’t change it but can make custom policy according to our needs.

Configuration files of SELinux There are two methods to configure the config file SELinux   1. Using GUI: You can access GUI through                              system>Administrator>SELinux management   

2. Manually via config file You can directly access the config file using any text editor like vim    using the location /etc/selinux/config Command to edit config file After the modification in config file we need to reboot the system and after that login to your system and view the cat /var/log/messages if you do not see any error then all is fine and all MAC policy are implemented successfully but if you observer any error then the chances are policy is not implemented successfully.When SELinux denies an action an Access vector is generated called AVC(access vector cache) which shows its message to /var/log/audit/audit.log and /var/log/messages, for troubleshooting use research to find any recent AVC messages. Config file of SELinux There are three basic mode for SELinux Permissive: SELinux is enabled but the MAC policies that are not                       Enforcing on the system only the warring to the user shows and a log of it displays.Enforcing: The default mode, strict mode enabling all policies and restrictions on the system.Disabled:  The default mode which is mainly present on the  system, SELinux is off in this mode. We can view the status of the current running mode of SELinux before editing the config file through “SEStatus” SEStatus Inside the config file, we also see SELINUXTYPE this option is used to set policy type which you want to use the default one is Targeted policy

Targeted:  default one which implements all the MAC policy (most restricted)

Minimum: Only selected processes are protected we have the                     liberty of modification of some  targeted made policy

Mis: server follows Multi-level security protection to prevent users from obtaining access to information for which they don’t authorize.

What you need to know about SELinux before you get started. SELinux stands for Security-Enhanced Linux. It is an update implemented within the security features of your current GNU/Linux derivative. So, we go back 20 years, when the NSA (National Security Agency) had realized that Linux was the future of INFOSEC. The agency dubbed Linux an architecture consisting of MAC (Mandatory access control). SELinux has lived up to its name as of yet, at every turn it has worked to beat back attempts to bypass application security. You may be a security, you may be afraid of those wannabe hackers/Elitists that are prowling; cautiously waiting for your data. You should know however, SELinux is not for everyone; SELinux requires: • Deep knowledge of Linux distros • Deep knowledge of the Linux Architecture • A lot of time/patience Setting SELinux up with no prior knowledge can land you in some trouble. If SELinux is deployed with no basic understanding of the setup, you will run into a handul of problems. The fundamental security approach of SELinux, is the exact opposite of Linux. SELinux is a plethora of Patches/User tools that add the touch of MAC security to your GNU/Linux OS. SELinux tools/patches defends the OS and enter any application that is misbehaving into a lockdown. Unix/Linux Security methodology is strictly discretionary access control (DAC); MAC is a new; a better approach. The omnipotency of the root user is the basis of DAC security. A flaw in a web server can allow an attacker to gain access to the web server group, thus allowing them to perform any modifications to files that they wish; “ Red Hat cloud strategy evangelist Thomas Cameron explained in a SELinux for Mere Mortals presentation, "You can chmod +rwx your home directory and nothing will stop you. We give you the gun, and there's your foot".   Work Cited Vaughan-Nichols, Steven, “How to set up SELinux right, the first time”, https://www.hpe.com/us/en/insights/articles/how-to-set-up-selinux-right-the-first-time- 1901.html January 22, 2019.

The Most Common Types of Access Control Systems

The best approach to ensure that only the individuals you trust have access to critical sections of your property is to use access control. All access control systems are not created equal. To restrict access within your house or company, there are four basic methods of access control. Access control systems help you to control access to sensitive data through a network. Cyber legend technologies LLC supplies the best access control systems in Dubai. They supply you the best to work out your business security efficiently.

Access control systems

By analysing needed login credentials, such as passwords, personal identification numbers (PINs), biometric scans, security tokens, or other authentication elements, access control systems provide identification, authentication, and authorisation of people and entities. Multifactor authentication (MFA), which needs two or more authentication factors, is frequently used to defend access control systems as part of a layered defence. The purpose of access control is to reduce the danger of unauthorised access to physical and logical systems posing a security risk. Access control is an important part of security compliance programmes because it guarantees that security technology and access control rules are in place to secure sensitive information like customer data.

Different Types of Access Control Systems Discretionary Access Control (DAC)

The owner of a firm can select how many individuals have access to a certain place using a discretionary access control system (DAC). A list of authorised users is kept at each access control point. When a keycard is swiped, a PIN is punched, or a fingerprint is scanned, the system compares the credential to the list and grants or refuses access based on the previously established permissions. When compared to other forms of access control, DAC systems are the most versatile and give the maximum number of permits. It is not as secure as certain other types, particularly required access control systems, because it is the most flexible.

Mandatory access control(MAC)

The military and other government institutions choose this choice since it is the most stringent. Based on the system administrator’s settings, the operating system tightly limits access to all doors. Users cannot update permissions that provide or restrict access to rooms throughout the institution using MAC.

Role-Based Access Control (RBAC)

Permissions are assigned to users based on their business responsibilities under role-based access control. The most popular access control method decides access based on your job title, guaranteeing that lower-level employees don’t have access to sensitive data. This strategy bases access privileges on a set of criteria that relate to the company, such as resource requirements, environment, employment, and geography. Most business owners prefer this method since it makes grouping staff based on the resources they require easier. Human resources personnel, for example, do not require access to private marketing materials, and marketing personnel do not require access to employee pay. RBAC is a flexible approach that improves visibility while also protecting against data breaches and leaks.

Web-based access control

This sort of access control software, also known as embedded access control, operates through a web browser application and connects to the LAN so that it may be accessed from any device on the network.

Attribute Access Control

Going a step further, this sort of system provides different dynamic and risk-aware controls based on the qualities assigned to a certain user. Consider these qualities to be parts of your user profile; when combined, they define your access. Once policies are in place, these qualities may be used to determine whether or not a user should have control.

Types of Access Control

Know more with the best Access Control Systems in Dubai

The goal of access control is to allow only those who are allowed to enter a building or workplace. For many years, the deadbolt lock and its accompanying brass key were the ultimate standard of access control; nevertheless, modern enterprises need more. They want to be able to regulate who comes and goes via their doors, but they also want to be able to monitor and manage access. Keys have now been handed over to computer-based electronic access control systems, which offer rapid and simple access to authorised individuals while prohibiting access to unauthorised individuals. You can easily buy Access Control Systems in Dubai from many suppliers.

Types of Access Control Systems

Discretionary Access Control (DAC)

The owner of the company can decide how many people have access to a specific location using a discretionary access control system (DAC). A list of authorised users is kept at each access control point. When a keycard is swiped, a PIN is punched, or a fingerprint is scanned, the system compares it to the list and either allows or denies access based on the previously set allowances. When compared to other types of access control, DAC systems are thought to be the most flexible and provide the most allowances. Because it is the most adaptable, it is also the least secure, especially when compared to other types, such as mandatory access control systems.

Mandatory Access Control (MAC)

The mandatory access control system provides the most stringent safeguards, with system administrators solely responsible for granting access. This means that users cannot change permissions that deny or allow them access to different areas, resulting in formidable security around sensitive data. It even limits the resource owner’s ability to grant access to anything on the system’s list. When an employee enters the system, they are assigned a unique connection of variable “tags” — similar to a digital security profile — that indicates the level of access they have. As a result, depending on the tags a user has, they will have limited access to resources due to the sensitivity of the information contained in them.

Role-Based Access Control (RBAC) –

RBAC, also known as a non-discretionary access control, is used when system administrators need to assign rights based on organizational roles instead of individual user accounts within an organization. It presents an opportunity for the organization to address the principle of ‘least privilege’. This gives an individual only the access needed to do their job, since access is connected to their job.

Rule-Based Access Control

Not to be confused with the other “RBAC,” rule-based access control is commonly used as an add-on to the other types of access control. In addition to whatever type of access control you choose, rule-based access control can change the permissions based on a specific set of rules created by the administrator.

If your business closes at 5 p.m., there’s no need for anyone to have access to your main office, even managers, after closing. With rule-based access control, you can set a rule to deny access to everyone from 5 p.m. to 9 a.m. the next morning. Rules can be created for just about any occasion.

What are the Benefits of Access Control Systems

Access Control Systems is a basic requirement of enterprises today. Both the need for security and for employee productivity require organizations to have an efficient and robust access control in place. There are some Benefits Of Access Control Systems which is ensures that only an authorized person can enter, view, use, or have access to a restricted environment.

What is Access Control System?

Access control refers to the practice of restricting entrance to a building, office or a room to only the authorized persons — employees, visitors, vendors etc. Access control can be done by various means — human intervention such as a guard or a receptionist, mechanical means such as lock and keys, or technology such as Access Control System

What is Access Control Software?

With the world adopting mobile, cloud and internet at a fast pace, access control systems are also undergoing a welcome change. There is increasing preference for digital, contactless interfaces and an attempt to move away from physical identity. This has given a fillip to development of Access Control Software, which is a huge improvement over the legacy technology used for access control so far. Access Control software is much more versatile, efficient and powerful than the traditional systems and at the same time, is contactless and pleasant to use.

Types of Access control:

There are various kinds of access control, basis the need and circumstances of a particular organization. Some of them are as under:

Manual access control — Securing specific access points through doormen, stewards or receptionists.

Mechanical access control — Putting flap barriers and turnstiles to control lift banks.

Electronic access systems — Using electronics in these access control mechanisms

IoT based Access Control — Using Internet of Things to make access control real-time and cost-effective

Access Control System can use various interfaces, such as:

Keypad readers. A keypad door reader requires a user to type in a PIN or passcode to unlock the door.

Swipe card readers.

RFID door readers.

Biometric door readers.

Smart lock door readers.

QR Code readers

Face Recognition Systems

Elements of Access Control System

Any access control system has the following four elements:

Access control barrier

Access control verification or identification equipment

Access control panel that controls the barrier

The communications structure that connects these elements and connects the system to the reaction elements.

Categories of Access Control Systems

Access control systems come in several variations but all can broadly be put into the following three categories:

Discretionary Access Control (DAC)

Managed Access Control (MAC)

Role-Based Access Control (RBAC)

Benefits of Access Control Systems

The purpose of an access control system is to provide quick, convenient access to authorized persons and restrict access to unauthorized people.

Following are some of the benefits that flow from a good access control system:

Increased ease of access for employees.

Saving money and energy.

Keeping track of movement of employees, visitors, vendors etc.

Protection against unwanted visitors.

Giving employees a peaceful and productive work environment

Prevention against data breach.

Increased security for sensitive areas.

The Access Control Problem

Access Control as an ecosystem is beset with many problems and is due for a major disruption.

Traditionally, access control systems have relied on physical identity for validation and authorization. This makes access control cumbersome, full of friction and inconvenient for the users. The majority of access control problems stem from lack of a structured flow, outdated equipment, keycards falling into the wrong hands, and a lack of integration with other building systems.

Then, there is the persistent problem of legacy technologies keeping cost of access control rather high. These technologies have remained same for decades now. Massive organizations have come up around these technologies, with huge overheads. They have captive clientele in the existing customers and they keep milking them by making the equipment obsolete at a fast clip, while keeping the underlying technology unchanged. Their interest is in perpetuating the system.

With advances in technology, most of the problems of the access control systems can be taken care of. Already, there is movement away from the traditional modes, interfaces and method. Digital identity is replacing physical identity and IoT will replace legacy technologies, making access control secure, convenient and cost-effective.

truMe, an IoT platform developed by three co-founders in India is in the forefront of this change. With truMe, access control becomes super-efficient, convenient and powerful at one tenth of the cost of the legacy technologies. Better days are ahead for Access Control systems.
