If audit data were to become compromised, then competent forensic analysis and discovery of the true source of potentially malicious system activity is difficult, if not impossible, to achieve.
The root role is required. This check applies to the global zone only. Determine the zone that you are currently securing. # zonename If the command output is "global", this check applies. Check that the directory storing the audit files is owned by root and has permissions 640 or less. Note: By default in Solaris 11.1, /var/audit is a link to /var/share/audit which is mounted on rpool/VARSHARE. Determine the location of the audit trail files # pfexec auditconfig -getplugin audit_binfile The output will appear in this form: Plugin: audit_binfile (active) Attributes: p_dir=/var/audit;p_fsize=0;p_minfree=1 The p_dir attribute defines the location of the audit directory. # ls -ld /var/share/audit Check the audit directory is owned by root, group is root, and permissions are 640 (rw- r-- ---) or less. If the permissions are excessive, this is a finding.

Lavender hyperlinks in small type off to the right (of CSS
class id, if you view the page source) point to
globally unique URIs for each document and item. Copy the
link location and paste anywhere you need to talk
unambiguously about these things.
You can obtain data about documents and items in other
formats. Simply provide an HTTP header Accept:
text/turtle or
Accept: application/rdf+xml.
