DISA Assured Compliance Assessment Solution (ACAS) Practice Test

The Nessus Network Monitor (NNM) is designed to provide visibility into network traffic, allowing organizations to assess and monitor their environment effectively. The statement that is true regarding the NNM indicates that it is capable of highlighting all interactive and encrypted network sessions. This capability is important because it allows security teams to identify sensitive traffic that may be traversing the network, even if the content of those sessions is encrypted. By highlighting these sessions, organizations gain insight into potential risks and can take appropriate security measures, such as investigating unusual patterns or behaviors in network traffic.

The ability to highlight encrypted sessions without decrypting them is critical for maintaining compliance and monitoring the security posture without compromising the integrity of sensitive data. This ensures that even as organizations implement encryption for privacy, they can still have visibility into how data flows across their networks.

In contrast, the other statements do not accurately describe the functions of the NNM. The NNM does not decrypt encrypted sessions; rather, it monitors and highlights them, which is essential for understanding network activity without violating data protection principles. Moreover, while the NNM is a powerful tool in a broader compliance strategy, it is not the only tool needed for comprehensive compliance with a task order—other tools and processes may also be required depending
