Description:
An account with an empty password field means that anybody may log in as that user without providing a password.
Rationale:
All accounts must have passwords or be locked to prevent the account from being used by an unauthorized user.
Remediation:
If any accounts in the /etc/shadow file do not have a password, run the following command to lock the account until it can be determined why it does not have a password:
# passwd -l
Also, check to see if the account is logged in and investigate what it is being used for to determine if it needs to be forced off.
Parameter:
[yes/no]
Technical Mechanism:
If any accounts in the /etc/shadow file do not have a password, run the following command to lock the account until it can be determined why it does not have a password:
# passwd -l username
Also, check to see if the account is logged in and investigate what it is being used for to determine if it needs to be forced off.
