Ha már ISMS auditor lennék

Az ember eljön egy viszonylag méretes szállodaláncba és naívan rákérdez, hogy mi is a Wifi? Flegma recepciós odavágja, hogy csak a közös területen van Wifi. Ha a szobába is akarok a akkor, leszek szíves 7 fontot leszúrni a kasszánál és 24 órára kapok valamit.

Aha, hát kösz nem. Nézzük a Wifi-t a biztonságos gépről, amin nincs olyan adat amiben kárt tenne valami fosadék net. Már ott elbukik, hogy a security rendszer óbégat, hogy nem biztonságos, nyilván wiresharkkal látnám az összes forgalmat. Mutatom bárisnyának a recepciónál, hogy látod nyuszika, itt óbégat a riasztás, hogy fosadék a hálózatotok. Erre ő, hogy meg kall adni az email címet, majd akkor kapcsolódhatók rendesen. Kapott eldobható email címet szórakozzanak azzal. Kapcsolódtam, de továbbra sem biztonságos a net. Mucikának mondom, hogy így sem jó, egy kalap fos a hálózatotok, erre ő, hogy lehet netezni nem? Különben sem kötelező használni.

Na itt triggerelt be. Most gyűjtöm ki az összes evidenciát, hogy milyen minősítésük van, milyen policyket adtak ki, milyen certificate-jeik vannak és minek nem felel meg a kurva hálózatuk. Kapnak olyan review-t, hogy a fal adja a másikat. Szarjanak aprószöget és beizzítom a hordozható hálózatot majd használom azon keresztül.

Ha tehetném befizetnék ide @muszeresz részére egy pár napos tanulmányutat, szerintem lubickolna.

 OSS Security, Myth, or Major Concern?

Open Source Software (OSS) is inside some of the most essential companies and applications for society worldwide. However, a persistent stigma around OSS security continues to hinder both innovation and widespread adoption. When it came to asking people what their main concern about OSS is, 53% said security.

Many people become worried when they see that the code base is open to anyone or that it could be unmaintained or written by people with bad coding habits. There is also concern that companies may neglect to track updates to the source code, leaving them with outdated versions that pose security risks. But are these concerns truly valid? And if so, does that necessarily make proprietary software safer than OSS? Let's look a little deeper into some of the main security concerns in OSS and then look at why OSS may be a lot safer than people think.

One of the main reasons people feel that OSS is unsafe is because the code base is not proprietary, meaning that anyone can look at all of the code that makes up the application. This worries people because if attackers can look at the code of an application, they believe that it would be very easy to find its vulnerabilities. Another reason people are often worried about the security of OSS is whether or not the code is maintained. Although rare, people fear that the contributors to the software they are using will either stop maintaining certain parts of their software or leave the project entirely. Another worry is that even if the code is being maintained, the company using the software might not update to the latest versions that are being put out. 

Outdated software, whether it is from the contributors not maintaining their software, or the company not acquiring the new updates, can lead to significant security risks. When a new update of software comes out companies will often publicly post the bugs and issues they fixed, which is informing all attackers what was wrong with the older versions. Some people also believe that those contributing to OSS are often immature and have bad developer practices. If the contributors were to have bad coding habits they could cause a lot of vulnerabilities such as hardcoding credentials or improper error handling. 

While these concerns hold some validity, discussions around OSS security often overlook that many of these risks also apply to proprietary software. Let's start with some security risks that don’t apply to proprietary software. An open code base is something unique to OSS, however, I believe that this aspect of OSS benefits its level of security more than it compromises it. 

There is a law called Linus’s Law named after Linus Torvalds (The creator of Linux) that says “Many eyes make any bug shallow”. This law refers to the thought that with enough contributors and coding enthusiasts looking at your code, a small amount of them might try and exploit the vulnerabilities they find, but the majority will alert the developers or fix it themselves. I believe in this law and that with many eyes looking at a codebase, vulnerabilities are more likely to be found but also addressed and remediated quickly. 

Another concern of those who feel that OSS is unsafe fear that companies may not keep up to date with the source code updates. Although this is a valid concern, it is not an issue with OSS, it is a problem with a company's internal processes. This should not be listed as a security concern of OSS because it is up to the individual to regularly update the newest software that is available.

All of these reasons for OSS being unsafe or safe can be debated and argued about, but physical data is much harder to ignore. The Coverity Scan Open Source Report is an annual report that analyzes the quality and security of OSS. This report states that the average OSS is of a higher quality than proprietary software. This data not only proves that contributors to OSS do not have bad coding habits, but it also proves that OSS, even though not perfect, is of a higher standard when it comes to security than proprietary software.

I believe the stigma that OSS is unsafe has limited the level of innovation and progress society has made in all realms of software. Who knows how many beneficial pieces of software could’ve been created if it weren't for this stigma, and how that software would affect the world?

The misconception that OSS is inherently unsafe has discouraged its adoption in many sectors, which limits opportunities for societal progress. This hesitancy has most likely curbed the development of groundbreaking solutions in areas like healthcare, education, and environmental sustainability, where open-source innovation could provide affordable and scalable tools for global challenges.

Addressing these misconceptions opens the door to greater innovation, allowing open-source communities to create secure, high-quality software that meets society's evolving needs.

Cyber Crime

Introduction

Crime and wrongdoing have been connected to people since ancient times. Even as societies develop, crime tries to hide itself. Different countries deal with crime in various ways, depending on their situation. It’s clear that a country with a lot of crime can’t grow or progress because crime goes against development. It has bad effects on society and the economy.

Cybercrime is when people commit crimes on the internet using computers. It’s hard to put crimes into specific groups since new ones come up often. In the real world, crimes like rape, murder, or theft can sometimes overlap. Cybercrimes involve both the computer and the person using it as victims. For example, hacking attacks a computer’s information and resources.

Computer as a Tool

When cybercriminals target individuals, the computer becomes a tool rather than the main goal. These crimes exploit human weaknesses and often cause psychological harm. Legal action against these crimes is challenging due to their intangible nature. Similar crimes have existed offline for centuries, but technology has given criminals new tools to reach more victims and evade capture.

Computer as a Target

Only a particular group of individuals carry out these actions. Unlike crimes where computers are merely tools, these activities demand the technical expertise of those involved. These kinds of crimes are relatively recent, coming into existence as long as computers have been around. This explains the lack of readiness in society and the world at large to combat these offenses. Such occurrences take place on the internet frequently. However, it’s worth noting that Africans and Nigerians, in particular, have not yet developed the technical knowledge required to engage in this type of activity.

Conventional Crime

Crime has been a part of human society for a long time and affects both society and the economy. It’s a term defined by the law and is subject to legal punishment. Crime is essentially a legal wrongdoing that can lead to criminal proceedings and penalties. The key aspect of a crime is that it breaks the criminal law. According to Lord Atkin, the determining factor for whether an act is criminal is whether it’s prohibited with penalties attached. A crime can be seen as any action or lack of action that goes against the law and results in legal penalties.

Cyber Crime

Cybercrime is the newest and most complex issue in the digital world. It can be understood as a type of crime where computers are either used as tools or are the focus of the criminal activity. Any illegal action that involves a computer as a means, target, or tool to commit further crimes falls under the category of cybercrime. A simple definition of cybercrime is “illegal activities where computers are involved as tools, targets, or both.” Computers can be tools in various activities like financial crimes, selling illegal items, pornography, online gambling, intellectual property theft, email deception, forgery, cyberbullying, and cyber harassment. On the other hand, computers can also be the target in cases like unauthorized access, stealing electronic information, email attacks, data manipulation, fraudulent actions, and physical harm to computer systems.

Distinction Between Conventional and Cyber Crime

Distinguishing between conventional and cybercrime might not seem obvious, but a closer look reveals an appreciable difference. The key distinction lies in the use of technology in cybercrime cases. The essential factor for cybercrime is the involvement of the virtual cyber medium at some point. In other words, cybercrime requires the use of digital platforms or the internet in its commission.

Here's something you need to hear from an IT person that you're being lied to about:

VPN's are not security software. They don't secure private data from people who are actually looking.

If you're truly worried about your data only visit your sensitive account sites from closed networks that you control.

All the above being said, I've heard that this needs to be approached with a bit more nuance:

Basically the first step is to make sure that you're connected to the legitimate hotel wifi, which means double check the SSID and password (if any!) at the front desk, so that you can gauge if the IP address assigned to you is a possible cause for concern.

The next step is to in general use a VPN for any personally secure stuff you need to do (yes, logging into AO3 counts, since a malicious actor could sign on as 'you' and delete all your fics just because they feel like being a piece of shit).

The final step is if you're at all unsure, disconnect immediately and wait until you can get to a place with known 'clean' wifi.

Good luck out there!
