Discussion

Without sufficient information to analyze the event, it would be difficult to establish, correlate, and investigate the events leading up to an outage or attack. Audit event content that must be included to satisfy this requirement includes, for example, time stamps, source and destination addresses, user/process identifiers, event descriptions, success/fail indications, filenames involved, and access control or flow control rules invoked. The firewall must also generate traffic log records when traffic is denied, restricted, or discarded as well as when attempts are made to send packets between security zones that are not authorized to communicate. Satisfies: SRG-NET-000075-FW-000010, SRG-NET-000076-FW-000011, SRG-NET-000077-FW-000012, SRG-NET-000078-FW-000013, SRG-NET-000399-FW-000008, SRG-NET-000492-FW-000006, SRG-NET-000493-FW-000007

Check Content

From the NSX-T Manager web interface, go to Security >> Gateway Firewall >> Gateway Specific Rules. 

For each Tier-1 Gateway and for each rule, click the gear icon and verify the Logging setting.

If Logging is not "Enabled", this is a finding.

Fix Text

From the NSX-T Manager web interface, go to Security >> Gateway Firewall >> Gateway Specific Rules. 

For each Tier-1 Gateway and for each rule with logging disabled, click the gear icon and enable Logging and then click "Apply".

After all changes are made, click "Publish".
