Nowadays many Linux servers are neither initially installed nor maintained by dedicated Linux administrators, yet IT professionals are responsible for their servers’ security. If your server is compromised, not only can all your sensitive information be exposed, but your server can also become a tool in the wrong hands. To avoid such scenarios, make sure your server is properly configured and regularly updated, and perform frequent security audits using the tools and procedures below.
The most effective Linux security audit is specially tailored to the applications and services running on your server. This means that you have to know the environment you are auditing. This allows you to determine where potential security risks are hidden and where your security scan should begin. For example, running a web server introduces the risk of vulnerable web scripts, which are one of the most common targets for hacker attacks. Not to mention that the running web server itself, or any of its modules, can be outdated and vulnerable or insecurely configured.
