System hardening
Any system providing ressources to the outside world is on risk to be hacked. Often simple security tools are installed and used by default like local firewalls, virus scanner etc., but even with these security measures in place, computers are often still vulnerable to outside access. System hardening, also called Operating System hardening, helps minimize these security vulnerabilities.
The trainings offered should provide detailed trainning on those tasks eliminating as many security risks as possible. The trainings should include e.g. technics to check for non-essential software programs which can be removed from the system, since they could provide "back-door" access to the system. Guest accounts should be closed, alternate boot devices disabled, only secure passwords allowed, no remote root access, monitoring of unauthorized access attempts, etc.
