Fix Recommendation

Configure the audit log files to be owned by "root" user.

First determine where the audit logs are stored with the following command:

# sudo grep -iw log_file /etc/audit/auditd.conf
log_file = /var/log/audit/audit.log

Using the path of the directory containing the audit logs, configure the audit log files to be owned by "root" user by using the following command:

# sudo chown root /var/log/audit/*

Check Contents

Verify that the audit log files are owned by "root" account.

First determine where the audit logs are stored with the following command:

# sudo grep -iw log_file /etc/audit/auditd.conf
log_file = /var/log/audit/audit.log

Using the path of the directory containing the audit logs, check if the audit log files are owned by the "root" user by using the following command:

# sudo stat -c "%n %U" /var/log/audit/*
/var/log/audit/audit.log root

If the audit log files are owned by an user other than "root", this is a finding.
