IPSec Communications Field Values

The other option in the IPSec Communications menu is to enable NAT. Only use this if NAT is set up between the management device and the sensor. If NAT is enabled, the result is encryption of IDS traffic only. TCP traffic is unencrypted. For added security, use SSH communications when NAT is enabled.

Some of the benefits from using IPSec are as follows:

• Secure communications between the management device and the sensor

• Traffic is encrypted between the nodes

• Authentication, confidentiality, and nonrepudiation protection for IDS communications
