The NSX-T Tier-0 Gateway Firewall must be configured to use the TLS or LI-TLS protocols to configure and secure communications with the central audit server.

Description

<VulnDiscussion>It is critical that when the network element is at risk of failing to process traffic logs as required, it takes action to mitigate the failure. Collected log data be secured and access restricted to authorized personnel. Methods of protection may include encryption or logical separation. In accordance with DOD policy, the traffic log must be sent to a central audit server. Ensure at least primary and secondary syslog servers are configured on the firewall. If the product inherently has the ability to store log records locally, the local log must also be secured. However, this requirement is not met since it calls for a use of a central audit server. This does not apply to traffic logs generated on behalf of the device itself (management). Some devices store traffic logs separately from the system logs.
