Malicious Activities

Malicious Activities

You should set a policy regarding malicious activities. These include:

deliberately crashing the system
breaking into other accounts; for example, using password-guessing and password-stealing programs
forging electronic mail from other users
creating and unleashing malicious programs, such as worm and virus processes

Make sure that all users at the site are aware that these sorts of activities are potentially very harmful to the community of users on the system. Penalties for malicious behavior should be severe and the enforcement should be consistent.

The most important thing you can do to prevent malicious damage to the system is to restrict access to the root password.
