The NSX-T Tier-0 Gateway Firewall must generate traffic log entries containing information to establish the details of the event.

An XCCDF Rule

Description

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-000074-FW-000009, 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
