Vulnerability discussion

It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Without a real-time alert, security personnel may be unaware of an impending failure of the audit capability, and system operation may be adversely affected. The appropriate support staff include, at a minimum, the ISSO and the DBA/SA.Alerts provide organizations with urgent messages. Real-time alerts provide these messages immediately (i.e., the time from event detection to alert occurs in seconds or less).

Check content

Review the system documentation to determine which audit failure events require real-time alerts. Review Postgres Enterprise Manager (PEM) alert settings. If the real-time alerting that is specified in the documentation is not enabled, this is a finding.

Fix text

Install PEM and configure audit failure event alerting as documented here: http://www.enterprisedb.com/docs/en/5.0/pemgetstarted/PEM_Getting_Started_Guide.1.28.html An example for creating an alert that ensure the audit directory does not fill up is included below, using the thin client (browser) PEM interface. Refer also to the Supplemental Procedures document, supplied with this STIG. Open the PEM web console in a browser - Log in - Click on the agent for the machine to be monitored - Select "Management | Probe Configuration" - Select "Disk Space" and set the check interval as you like - Select "Management | Alerting" - Name the definition "Audit Log Full" - Select Template "Disk Consumption Percentage" - Set Frequency, Comparison Operator, and Thresholds (1 minute, >, 95/96/97 for example) - Enter the Mount Point for where the audit log is - Click Notification tab - Click Email all alerts - Click "Execute Script" on Monitored Server

Pro Tips

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.
