Accounts providing no operational purpose provide additional opportunities for system compromise. Unnecessary accounts include user accounts for individuals not requiring access to the system and application accounts for applications not installed on the system.
Check the system for unnecessary user accounts. # getent passwd Some examples of unnecessary accounts include games, news, gopher, ftp, and lp. If any unnecessary accounts are found, this is a finding.
The root role is required. Remove all unnecessary accounts, such as games, from the /etc/passwd file before connecting a system to the network. Other accounts, such as news and gopher, associated with a service not in use should also be removed. Identify unnecessary accounts. # getent passwd Remove unnecessary accounts. # userdel [username]
