Linux is a widespread OS known for its robust security. That being said, vulnerabilities are inevitable in any OS, and Linux system administrators must be vigilant about monitoring and verifying the security of their servers on an ongoing basis in order to protect sensitive data and prevent attacks. After all, the majority of attacks on Linux systems can be attributed to poor administration.
