Title

Symantec ProxySG must produce audit records containing information to establish when (date and time) the events occurred. (Cat II impact)

Discussion

Without establishing when events occurred, it is impossible to establish, correlate, and investigate the events leading up to an outage or attack. In order to compile an accurate risk assessment and provide forensic analysis of network traffic patterns, it is essential for security personnel to know when flow control events occurred within the infrastructure. Associating event types with detected events in the network audit logs provides a means of investigating an attack, recognizing resource utilization or capacity thresholds, or identifying an improperly configured network element. This requirement does not apply to audit logs generated on behalf of the device itself (management).

Check Content

Verify that the ProxySG is configured to log user web traffic for auditing that includes the date/time of the event. 1. Log on to the Web Management Console. 2. Browse to "Configuration" and click "Access Logging". Verify that "Enable Access Logging" is checked. 3. Browse to "Access Logging", click "General," and note which Default Log is indicated for the HTTP protocol ("main" by default). 4. Click "Formats," select the Default Log from step 3, and click "Edit/View". 5. Review the log format string and verify that the "date" and "time" variables are included. If Access Logging is not enabled and/or the specified log variables are not included, this is a finding.
