SYMP-AG-000190 - Symantec ProxySG must produce audit records containing information to establish the outcome of the events.

Information

Without information about the outcome of events, security personnel cannot make an accurate assessment as to whether an attack was successful or if changes were made to the security state of the network.

Event outcomes can include indicators of event success or failure and event-specific results (e.g., the security state of the network after the event occurred). They also provide a means to measure the impact of an event and help authorized personnel to determine the appropriate response.

This requirement does not apply to audit logs generated on behalf of the device itself (management).

Solution

Configure the ProxySG to log user web traffic for auditing that includes information about the outcome of the event.

1. Log on to the Web Management Console.
2. Browse to 'Configuration' and click 'Access Logging'. Check 'Enable Access Logging' and click 'Apply'.
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. Edit the log format string to include at least the following variables:
s-action
rs-response-line
rs-status
sc-status
x-exception-reason
duration
6. Click OK >> Apply.
