9 Ways to Make Linux More Secure
The Linux operating system has already been proven to be very reliable and secure. It is often the most popular operating system found on web servers largely accredited to its track record in security, but can it be improved?
1. Use SELinux
Security Enhanced Linux was originally developed for The National Security Agency and is now merged with the 2.6 kernel to provide some additional security measures to the Linux operating system. Enabling SELinux is probably one of the most important things you can do if you care about creating a ridiculously secure operating system.
2. Subscribe to a Vulnerability Alert Service
Often times it is not the operating system itself that is vulnerable. Vulnerabilities are usually found in the applications and additional services that are installed on the system itself. One of the best ways to stay secure is to make sure you have the latest version of the application and that there are no known vulnerabilities for the version you have.
