Description: OpenBSD is an operating system known for its focus on security and code correctness. Among its most notable security features is secure memory management, which helps prevent vulnerabilities such as buffer overflows. This technique ensures that memory is handled in a way that data is not accidentally overwritten, which could allow an attacker to execute malicious code. Additionally, OpenBSD implements address space layout randomization (ASLR), a measure that makes it difficult to predict the memory addresses where processes are loaded, thus complicating attempts to exploit vulnerabilities. Another important feature is the use of ‘secure by default’, meaning that many security configurations are enabled by default, reducing the attack surface from the outset. OpenBSD also includes robust cryptographic tools and a focus on code review, where every change is carefully examined for potential security flaws. These features make OpenBSD a preferred choice for environments where security is critical, such as servers and embedded systems. In summary, OpenBSD not only focuses on providing a functional operating system but also prioritizes security in every aspect of its design and operation.
