| Finding ID | Severity | Title | Description |
|---|---|---|---|
| V-251738 | 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. | 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. Colle... | |
| V-251739 | The NSX-T Tier-0 Gateway Firewall must block outbound traffic containing denial-of-service (DoS) attacks to protect against the use of internal information systems to launch any DoS attacks against other networks or endpoints. | DoS attacks can take multiple forms but have the common objective of overloading or blocking a network or host to deny or seriously degrade performanc... | |
| V-251740 | The NSX-T Tier-1 Gateway Firewall must deny network communications traffic by default and allow network communications traffic by exception (i.e., deny all, permit by exception). | To prevent malicious or accidental leakage of traffic, organizations must implement a deny-by-default security posture at the network perimeter. Such ... | |
| V-251741 | The NSX-T Tier-0 Gateway Firewall must employ filters that prevent or limit the effects of all types of commonly known denial-of-service (DoS) attacks, including flooding, packet sweeps, and unauthorized port scanning. | Not configuring a key boundary security protection device, such as the firewall, against commonly known attacks is an immediate threat to the protecte... | |
| V-251742 | The NSX-T Tier-0 Gateway Firewall must apply ingress filters to traffic that is inbound to the network through any active external interface. | Unrestricted traffic to the trusted networks may contain malicious traffic that poses a threat to an enclave or to other connected networks. Additiona... | |
| V-251743 | The NSX-T Tier-0 Gateway Firewall must configure SpoofGuard to block outbound IP packets that contain illegitimate packet attributes. | If outbound communications traffic is not filtered, hostile activity intended to harm other networks may not be detected and prevented.... | |
| V-251737 | The NSX-T Tier-0 Gateway Firewall must generate traffic log entries containing information to establish the details of the event. | Without sufficient information to analyze the event, it would be difficult to establish, correlate, and investigate the events leading up to an outage... |
