Open Source FOSS - Details and examples

 The term "Free Open-Source Software," or FOSS for short, refers to a type of computer software that groups together applications with open-source code and freely available licenses. Downloading, using, and researching software that is open-source and community-developed does not cost anything. This article will concentrate on the fundamental distinctions between free and open-source software (also known as OSS or open-source software), as well as the application of the program and the many security flaws that are linked with it. Enjoy!

Concerning Open-Source and Free Software.

In popular usage, free and open-source software (FOSS) and open-source software (OSS) are often considered to be synonymous with one another, if not the same thing. This is not the case, however; free and open-source software (FOSS) is more concerned with the moral implications of software usage, distribution, and modification, whereas open-source software (OSS) is heavily focused on the practical aspects of sharing and permitting community members to modify the (original) source code. In order for us to comprehend the significance of these repercussions, we will need to go through time to the early 1980s.

Richard Stallman, a graduate of the Massachusetts Institute of Technology who is also an activist in the field of computer software, puts a plan into action in 1983 to bring software closer to the end user. Stallman and the community of programmers he led vigorously pushed for the user's (inalienable) right to freely use, change, and distribute code. Stallman believed that these rights had been rendered null and void by the rapidly expanding computer business.

Because to his effort, the Free Software Foundation (FSF), the GNU Project, and, of course, the GNU Manifesto were all able to come into being. Linus Torvalds, who would go on to design both the modular and the monolithic Linux kernel, would find his inspiration in the work done by Stallman's group.

Comparing Free Open-Source Software (FOSS) to Open-Source Software (OSS) and Cascading Style Sheets (CSS) (Closed-Source Software)

As you can see, free and open-source software (FOSS) has a long and storied history in the realm of computer software. Its origins can be traced back to an all-out revolt against the licensing and "packaging" practices of software producers. Why is it important to learn about this part of our past? The primary reason for this is because we have now been able to decipher what the "F" in "FOSS" stands for, and contrary to popular belief, it does not stand for "free." It is a reference to the notion that you, as a user, do not need to be concerned about breaking any copyright restrictions in order to make copies of the program, use it, alter it, or study it. As a result, the following facts have been established:

The cost of using FOSS software is not zero.

It is up to the user to make any necessary adjustments, and they are even allowed to discuss their modifications with other users.

There is a significant emphasis on ethics in FOSS.

Free and open-source software (FOSS) is best shown by Linux and other operating systems that are similar to UNIX.

And now for the question that everyone has been waiting for: can OSS be FOSS? Or, to put it another way, can you tell me whether there are any distinctions between open-source software and free open-source software? However, according to the law, the answer is yes. When it comes to open source software (OSS), any kind of computer program that falls under this category may be distributed among the members of the community, who have the ability to modify the source code and even make money off of the enhanced version of the program.

The similarities to FOSS are striking, don't you think? There is just one problem with this, and that is the license agreement. The usage of any Open-Source Program is subject to the terms of a license agreement, which details the user's rights and responsibilities in relation to the software and, of course, its source code. For instance, some producers of open-source software could make it possible for users to modify the source code, but they might restrict the user from redistributing or selling the modified version.

On the other hand, some developers may look the other way if you modify, distribute, or monetize the source code, but they may charge you for providing you with access to it. There are a lot of different permutations, and the license agreement is at the center of each and every one of them. Makes perfect sense, doesn't it, that some OSS can also be FOSS, but not all FOSS can also be OSS?

Now, the Free Software Directory, which is one of the largest and certainly one of the oldest FOSS repositories, is the greatest site to gather extra information about program. This is true regardless of whether the software is classified under FOSS, OSS, or anything in between (over 15,000 projects and GNU packages). Make sure you visit their website so that you may download software, learn about history, and purchase souvenirs.

Free and open-source software (FOSS) is not only about philosophizing; it also has a pragmatism about it and a very clear aim. This objective is to increase knowledge while producing a product that better benefits the community, and what better way to do so than via collaboration? The community is the driving force behind both FOSS and OSS.

In the next part, which will be devoted to security flaws that are peculiar to FOSS, we will discuss this topic in further detail. In any case, to cut a long tale short, there are perks and drawbacks associated with RDI, which is software that is driven by the community (Research, Development, and Improvement). To mention just a few benefits, we provide bug tracking and removal. Given that the code is easily accessible, it is far simpler to locate and eliminate software flaws in comparison to CSS (we'll discuss that in a moment). There is also the issue of education; both open-source software and free open-source software encourage new learning and innovative ideas.

Let's discuss CSS now that we have a very solid understanding of what free and open-source software (FOSS) and open-source software (OSS) are. Closed-Source Software is the abbreviation for this kind of software, which, as its name indicates, does not let the user to make any changes to, or otherwise interfere with, the program's source code.

Only the purposes for which CSS was designed may be carried out using the software; these functions are specified in the licence agreement. Oh, that's right; you have to pay to make use of any CSS. You must be in compliance with the terms of the license agreement in order to use the product and only those directly engaged in the creation of the product have access to the product's source code. A notable example of CSS is Microsoft's Windows operating system. Therefore, there is not much space for manoeuvre in this situation.

Now that we have a better understanding of the distinctions between FOSS, OSS, and CSS, let's turn our attention to the topic of security.

Concerns Regarding the Safety of Free and Open Source Software and Their Limitations

To begin, I believe that it would only be fair to speak about the issue that has been brought to everyone's attention — the availability of the code. Because the source code is considered to be in the "public domain," it follows that anybody, including hackers, is free to try their hand at modifying it. In practice, what this means is that programs constructed in an OSS approach may be more prone to exploitation in comparison to apps constructed using proprietary software. Do you think it's all just a myth? Somewhere in between. According to the research carried out by Russell Clarke and David Dorwin of the Department of Homeland Security and published under the title "Is Open-Source Software More Secure?,"

Open-source software does not create any significant new security risks; rather, it encourages good security practices by involving a large number of people who are able to spot vulnerabilities more quickly. Additionally, open-source software has the added benefit of offering side effects that supply clients and the community with concrete examples of code that is reusable, safe, and functional.

Because of this, there is no competition between open-source and closed-source software in terms of security. Both types of software include flaws that threat actors, who are often motivated by the (possible) economic rewards, may or may not exploit. Therefore, there is no evidence to support either the claim that closed-source software is more secure than open-source software or the opposite claim that open-source software is more safe than closed-source software.

Despite this, free and open-source software (FOSS) excels in some areas where proprietary software falls short. Finding a vulnerability is made more simpler and more time and effort efficient by the fact that this is a communal effort. Consider this for a moment: which of the two options is superior? A society structured like a beehive in which every member contributes to the process of locating a bug, or a confined space containing just a few individuals? There is power in both their numbers and the evaluations of their peers.

And because we are discussing open source software and free software vulnerabilities, here are a handful of examples of each:


An open-source software called Decompress has given WinRAR the appearance of a difficult math course. However, back a few years ago, it was discovered that decompress included a rather severe vulnerability known as an Arbitrary File Write vulnerability. This flaw would have allowed threat actors to write to system directories if they exploited it.


For the purpose of Java to XML serialization, XStream is a fairly handy little gimmick. It was revealed not too long ago that all versions prior to 1.14.44 were vulnerable to remote code execution (Remote Code Execution).


PyYAML is a fantastic open-source software that is used for parsing and a variety of other tasks. We are all familiar with and like Python. Despite this, there were a few problems along the way. Researchers in the field of information security found that versions lower than 5.3.1 were susceptible to RCE, similar as XStream.


Let's go over the facts one more time before we wrap up this piece on free and open-source software (FOSS). Free Open-Source Software is not free in the sense that it does not cost anything. The term "Free" refers to the user's entitlement to make additional, non-intended applications of the program. Furthermore, there is no evidence to support the claim that open-source software is more secure than proprietary software; both types of software have their advantages and disadvantages.
