Some accounts are not associated with a human
user of the system, and exist to perform some administrative
function. Should an attacker be able to log into these accounts,
they should not be granted access to a shell.
The login shell for each local account is stored in the last field of each line
in '/etc/passwd'. System accounts are those user accounts with a user ID less than
1000. The user ID is stored in the third field.
If any system account
Parameter:
[UID_1/UID_2]
Technical Mechanism:
Ensuring shells are not given to system accounts upon login
makes it more difficult for attackers to make use of
system accounts.
