Ensure sshd LogLevel is configured

MoyenneNiveau 1Automatiséeaix

Description

SSH provides several logging levels with varying amounts of verbosity. The DEBUG options are specifically not recommended other than strictly for debugging SSH communications. These levels provide so much data that it is difficult to identify important security information, and may violate the privacy of users. Audit: evaluates the effective configuration from `sshd -T` (Match blocks must be reviewed separately).

Méthode de vérification

Méthode d'audit: Commande shell

shell

command -v sshd >/dev/null 2>&1 || exit 1; out=$(sshd -T 2>/dev/null) || exit 1; r=compliant; for p in '^loglevel[[:blank:]]+(VERBOSE|INFO)$'; do printf '%s\n' "$out" | grep -Eiq -- "$p" || r="not matched: $p"; done; echo "$r"

Sortie attendue: compliant

Méthode de correction

Méthode de correction: Recommandation ou correctif d'infrastructure

Edit the /etc/ssh/sshd_config file to set the parameter above any Match set entries as follows: LogLevel VERBOSE - OR - LogLevel INFO Re-cycle the sshd daemon to pick up the configuration changes: stopsrc -s sshd startsrc -s sshd Note: First occurrence of a option takes precedence, Match set statements withstanding.
