What is Firewall ? Importance of Firewall in Network Security .

What is Firewall ? Importance of Firewall in Network.

A firewall is a system that is designed to prevent Unauthorized access from entering a private internal and external network. A firewall creates a secured barrier between a private network and the public internet network. This protects your network from 'hackers' logging into the machine. A firewall blocks traffic from the outside to the inside. A firewall is most especially important to large organizations. A firewall can be implemented in both hardware-based and software-based or a combination of both.   What does the firewall do? Firewall protects your personal information from hackers. A firewall limits you expose _ blocks "pop up" ads and certain cookies. Firewalls are manage and control inside and outside network traffic. Firewall blocks malicious data, massage, application, port number,  protocol, packet based on content, source address. A firewall is capable of hiding the structure and addressing the scheme of a private network from the public. Firewall examines all traffic route between two the network to see if it meets certain cleataria. Firewalls can be filter packets based on their source and target address and port numbers. It is known as address filtering. Why the firewall used on the computer? Firewall can help to secure your computer. If you have more than connect in the home, or if you have a small office network it's important to provide security every computer. You should have a hardware firewall (like as router)have to protect your network so you should be using a software firewall in your each computing device to prevent the spreading virus. A host-based firewall host computer. Its control inbound and outbound traffic in your network and protect your sensitive information from hackers.

Types of firewall:

Packet-filtering firewall A packet filter firewall is the simplest firewall. It is used to control network access by incoming and outgoing packers. The firewall applied its rule set to determine which packets allow or disallow. It examines each on the source of IP address, destination of IP address, TCP/UPD source port, TCP/USD destination port. It's also called static filtering. Circuit level gateway Circuit level gateway work at the session layer of the OSI model. It is set up between TCP/IP connect. It supports much protocol and easy to maintain. It is protected external traffic on the network. An example of this is the SOCKS packet. Stateful inspection firewall Stateful inspection is a firewall technology it can monitor the state of actuating network connections to use this information of determining which network packets to allow through the firewall. Stateful inspection analysis packets down to the application layer. Its also called dynamic packets filtering. Application-level gateway ( proxy firewall)  The application-level gateway can give high-level security. The gateway can be configured to support application-level or proxy service inbound connection circuit-level function for outbound connection. It is service-specific. It acts as a really of application-level traffic. The only allowable application can be passed through. Next-generation  firewall Next-generation firewall (NGFW) is an advance version of the traditional firewall. It is a part of third-generation technology. It provides proper Security. It blocks malware from entering the network. Next-generation firewall improving filtering network traffic on packets contents. Software firewall A software firewall protects a single computer. It protects internal systems. Usually, the software firewall is less expensive and it's easier to configure. The software firewall intercepts each connection request and determines whether the request allows or not allow. Hardware firewall A hardware firewall protects the whole network. It is an implemented router label. It can provide high speed and higher security. Hardware firewall easily integrated with other security features like DLP, IPS/IDS Sandboxing, deep packet inspection. It is usually expensive. Cloud-based firewall The cloud-based firewall protects the network from cyber attacks direct at these cloud assets. The Cloud firewall has two flavors-vanilla and strawberry. Both are software. It blocks malicious traffic. Read the full article

What Is HTTPS and Why Should I Care?

What Is HTTPS and Why Should I Care?

What is https://www.com?   What Is HTTPS? You must have been into web pages on your browser and we required to submit information like your password or credit card number which is something you don't want to share with everybody. For example, if I want to access my Gmail account I have to send my username and password to the Gmail web server so that it cannot indicate my account. But the data that I send to the Gmail server actually goes over the internet which is kind of owned by different companies in parts. The internet service provider that use might be Verizon or a TNT so when you actually connect to the internet you are on your service provider’s network. Let’s Verizon for example. The data you send goes over the Verizon network to maybe few other networks before it finally arrived at the mail server, now I am not saying that one really does but it is possible for a person in one of such companies who have proper access to the network to be able to see the data that one my send over the internet. What is the full form of https?     Hypertext Transper Protocol Secure.  Uses of https? 1.https is secure for website owners and users. 2.https transfer text, audio, video, financial and confidential information one to another device. 3. It is a protocol for a secure way to transfer data between a web server and a browser. 4.https protect our sensitive conversation by hackers. SSL     If the data that I sent over the network is sensitive like the credit card information while making an online payment on the bank account information. It can be a lot of trouble for people of someone on the internet is able to capture it and misuse it, sending data over the internet following the HTTP protocol is like sending some items through a courier service without securing it in a lockbox. So new protocol to handle secure data transfer was invented for handling valuable sensitive data. This protocol was called the SSL (short for secure socket layer).          https is nothing but the HTTP protocol working in tandem with SSL. that is in https SSL takes care of making sure that the data goes securely over the internet. So let's understand SSL now but before we can understand SSL we must be aware of some concepts of Cryptography on which SLS paste. What is the difference between HTTP and HTTPS? HTTPS HTTP 1.URL begins with https://te 2.https full from is hypertext Transfer protocol secure. 3.https operate on TCP/IP protocol. 4.https is a more secure transfer protocol. 5.https used port no is 443. 6. https can not be attacked by hackers. 7.https operate transfer layer. 8.https required by SSL certificate. 9.https is slower than https. 1o.It data has encrypted. 1. URL beginning with http:// 2.http full from is hypertext Transfer protocol. 3.http is operated TCL  protocol. 4.http is less secure transfer protocol. 5.http used port no is 80. 6.http can be hacked. 7.http operate application layer. 8.No SSL certificate is required by HTTP. 9.http is faster than HTTP. 1o.Its data is not encrypted. What does https works? 1.https is a secured version of https. 2.https sent data browser to a website. It communicates browser and website.   3.https protect our sensitive confidential information when we do any transaction like online shopping, banking, any type of confidential work. 4.https has a green color address bar which shows that it was secured. 5.https is required by a secure socket layer (SSL) certificate. Why we should use https? 1.we should use https because it protects the privacy and security of your users. 2. It protects user's personal conversation and data transfer and any other transaction stolen by hackers. 3.https introduction to the service worker. .4.https has many powerful features. 5.htts helps to improve search ranking. What are disadvantaged using https? 1. Using https for a web request will always slow than HTTP. 2. Pages with https can never be cached is a  shared cache.

What is an IP address

What is an IP address?

IP (internet protocol) is the protocol by which is sent data from one computer to another device on the internet. Each computer on the internet has different IP address identify it from all other computers on the internet. An IP address is a numeric address and identifier for a computer or device on a network. Every device has and has an IP address for communication purposes. The IP address consists of 2 parts. The first part is the network address and the second part is the host address. There also two types of IP addresses the first one is the most common one is called IP version 4 (IPv4) and a second type is IP version 6 (IPv6)

  Internet protocol version 4 (IPv4)

Internet protocol version 4 (IPv4) is the fourth version of the internet protocol (IP). This protocol most used today in data communications over different kinds of the network because it supports all devices.IPv4 invented in 1970. Is IP version 6 4 is the current version (not for long) of IP addresses. 32-bit numeric address written as four numbers separated by periods (55.68.236.15).

This Picture created by Kironmoy Roy Each group of numbers that are separated by period is called in architect. The number range in chartered is equal 0 to 255. This address bro Shankar produced over probably 4.3 billion unique addresses.  

Internet protocol version 6 (IPv6)

Internet protocol version 6 (IPv6) It is the most recent update version protocol of the internet. That provides an identification and location system for computers and routes traffic across the internet. IPv6 invented in 1998. On the internet first developed a program that realizes have big would become. They thought IP version 4 Which produced over 4 billion addresses would be enough, but they were wrong.  IP version 6 is the next generation of IP addresses. The main difference between IP version 4 and IP version 6 is the link to the address. The IP version 4 address is its 32-bit numeric address. Where is IP version 6 is a 128-bit hexadecimal address? Hexadecimal uses both numbers and alphabets in the address.

This Picture created by Kironmoy Roy So with this type of address, IP version 6 can produce an unbelievable 340 and 10 Alien IP addresses does the number 340 with 36 digits afterward guest IP version sex is more than enough for the foreseeable future. So study before IP version 6 is a hundred and twenty-eight (128) bit hexadecimal address. It is made up of 8 sets of 16 bits. With 8 sides are separated by Collins.

DIFFERENCE BETWEEN IPv4 VS IPv6

This Picture created by Kironmoy Roy IPv4 IPv6 1.IPv4 is a 32-bit address. 1.IPv6 IS 128-bit address. 2.IPv4 is the numbering address method. 2.IPv6 is the alphanumeric address method. 3.IPv4 binary bits are separate by dot(.) 3.IPv6 binary bits are separate by a colon(:). 4.IPv4 has a different 5 class of IP addresses. Class A, Class B, Class C, Class D, Class E 4.IPv6 does not have any different types of IP addresses. 5.IPv4 has a limited number of IP addresses. 5.IPv6 has an unlimited number of IP addresses. 6. An example of an IPvs4 address is  357. 169.05 34. 6.Example of IPv6 address is  F3oo:89A9:ABCF:7987:AB84:G00T:9874:VWXY. 7.IPvp4 has 12 numbers of header filed. 7.IPv6 has 8 number of header filed. 8.IPv4 length of the header filed is 20-60. 8.IPv6 length of the header filed is 4o. 9.IPv4 has availableChechecksum field. 9.IPv6 has not available any Chechecksum field. 10.IPv4 pocket size is 576 bytes. 10.IPv6 pocket size is 1280 bytes. 11.IPv4 has an available optional filed. 11.IPv6 has not available an optional filed. 12.IPv4 is less secured. 12.IPv6 is more than required compared to IPv4. 13.IP sec support is optional in IPv4. 13.IP sec support is required in IPv6. 14.IPv4 uses both multicast and broadcast m passage transformation scheme. 14.IPv6 doesn't use broadcast uses a different type of multicast massage transformation scheme. 15.IPv4 supports VLSM (Virtual Length Subnet Mask). 15.IPv6 doesn't support VLSM.     IPv4 and IPV6are applied to identify a device connected to a network. I principle, they are similar but they are various in how they work. IPv4 and IPv6 are cannot communicate with other network but it can exist together on a similar network. This is called Dual Stack.
