System Hardening aims to carry out the updates, adjustments and changes needed to reach a high level of security against external and internal attacks.
A hardening process needs to go beyond applying patches and updates. To improve the security of a system, it is essential to know in detail the options offered by operating systems and server applications, many of which remain hidden or are not used in default configurations.
This process, known as hardening, consists of strengthening the security of a server, starting from a standard installation and taking advantage of the resources and capabilities of the operating system itself to reach the highest possible level of security.
