ROS (Robot Operating System)
TMA-ROS1-6.2.1
Ensure password fields are not empty
Description
An account with an empty password field means that anybody may log in as that user without providing a password. The audit requires every account in /etc/shadow to have a non-empty password field. Host-level control from the CIS ROS Melodic benchmark (Ubuntu 18.04 robot hosts); run as root.
Méthode de vérification
Méthode d'audit: Commande shell
[ -r /etc/shadow ] || exit 1
u=$(awk -F: '($2 == "") {print $1}' /etc/shadow)
[ -z "$u" ] && echo compliant || echo "accounts without password: $(printf '%s ' $u)"- Sortie attendue
compliant
Méthode de correction
Méthode de correction: Recommandation ou correctif d'infrastructure
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.
