The maintenance of IT security is a sustained process for which the corresponding tasks must be continually repeated.

  • Observe the information in the 'IT security notices' chapter.
  • Install security updates regularly.
  • Run a risk analysis on the security properties of the applied software at regular intervals.

You will find information on a corresponding risk analysis here, for example:
