Software starts[ edit ] Until the late s computers—large and expensive mainframe computersmachines in specially air-conditioned computer rooms—were leased to customers rather than sold. Computer vendors usually provided the source code for installed software to customers.
Jason MillerIn the age old battle between open source and closed source operating systems and applications, can either of them really be considered more secure than the other?
After all, at its most basic level, security is about knowledge and understanding. During this discussion, I talked about how open source software can make security easier.
What I want to clarify in this article are my thoughts on the security of open source systems versus closed source systems. Which one is more secure?
Understanding how something works which is important when securing a systemor the processes through which it was made, can oftentimes be difficult or impossible, as the only readily available insight into this information in the documentation provided by the vendor.
This, however, has the interesting side effect of Closed source systems attacks against such a system more difficult. An attacker typically needs to understand a system before he can find and exploit a vulnerability in it.
Security by obscurity you say? Open source systems, on the other hand, by their very nature, are open to scrutiny.
Nothing is hidden from view, and nothing must be taken as gospel from the documentation. Perhaps this is somewhat of an oversimplification, but it ultimately does represent the core philosophy of open source. This, conversely, can make an attackers job easier. However, does this really make an open source project less secure?
Although real-world examples might seem to lean one way or another, ultimately, making judgments about a projects security based on the openness of its source code is a shallow conclusion, at best. It could be said that security, although affected by the openness of a projects source code, is not necessarily directly related to it.
Secure design, source code auditing, quality developers, design process, and other factors, all play into the security of a project, and none of these are directly related to a project being open or closed source.
I must admit, however, that I have been shocked at the existence of certain types of vulnerabilities in some closed source projects. Does this mean that closed source projects are immune to exploitation through these types of vulnerabilities? But from a more pragmatic standpoint, it does seem to severely hamper an attackers ability to find them.
And in the end, they all bring us to the same point: As a security professional, you need to be aware of risk, and the specific threats that are related to your infrastructure. And we all know that manging risk is a very important part of security.
Ultimately, when it comes down to it, security is about more than just being closed source or open source, its about a process.Oct 01, · Open Source Versus Closed Source Security Jason Miller, In the age old battle between open source and closed source operating systems and applications, can either of them really be considered more secure than the other?
Closed Source or Bi-Wave Systems. Closed Source systems of bi-wave, anti-life reversals and fragmented polarity consciousness within the planetary field are falling into descension spirals, and then being transmuted into smaller units and transited out.
Proprietary software also known as "Closed Source Software" is non-free computer software for which the software's publisher or another person retains intellectual property rights—usually copyright of the source code, but sometimes patent rights. Open and Closed Source Systems Essay Words Jan 13th, 6 Pages An operating system is a considered a set of programs that schedule tasks, assign storage and presenting an interface to the user.
Closed-source operating systems use code that is proprietary and kept secret to prevent its use by other entities. Traditionally, they are sold for a profit. Open-source. We're going to take a look at service/support, innovation, usability and security in both open source and closed source software and outline the pros and cons of both software systems.
So What Are Some of The Key Differences Between Open & Closed Source Software?
