Preventing Unintentional Misuse of System Resources

You can prevent you and your users from making unintentional errors in the following ways:

• You can keep from running a Trojan horse by correctly setting the PATH variable.

• You can assign a restricted shell to users. A restricted shell prevents user error by steering users to those parts of the system that the users need for their jobs. In fact, through careful setup, you can ensure that users access only those parts of the system that help the users work efficiently.

• You can set restrictive permissions on files that users do not need to access.
