Assessment Title

Rule Text

TOSS audit log directory must be owned by group root to prevent unauthorized read access.

Description

Discussion Text

Unauthorized disclosure of audit records can reveal system and configuration data to attackers, thus compromising its confidentiality. Audit information includes all information (e.g., audit records, audit settings, audit reports) needed to successfully audit operating system activity. Satisfies: SRG-OS-000057-GPOS-00027, SRG-OS-000058-GPOS-00028, SRG-OS-000059-GPOS-00029

if [ -z "$audit_log_directory" ]; then echo "PASS"; exit 0; fi
if [ ! -d "$audit_log_directory" ]; then echo "PASS"; exit 0; fi
if [ "$(stat -c "%G" "$audit_log_directory")" = "root" ]; then echo "PASS"; exit 0; else sudo chgrp root "$audit_log_directory"; fi
echo "FAIL"; exit 1

Remediation

Configure the audit log directory to be protected from unauthorized read access, by setting the correct group as "root" with the following command:

$ sudo chgrp root [audit_log_directory]

Replace "[audit_log_directory]" to the correct audit log directory path, by default this location is "/var/log/audit/."
