What session flag signifies that the traffic will be checked by an IPS signature?

The session flag "ndr" indicates that the traffic will be checked by an Intrusion Prevention System (IPS) signature. When this flag is set, it tells the firewall that the corresponding session should undergo inspection for any potentially malicious activity, utilizing the IPS capabilities to analyze the traffic against its defined signatures and rules. This proactive measure helps in identifying and mitigating threats in real time, ensuring that only legitimate traffic is allowed while potentially harmful traffic is blocked.

The other options do not specifically relate to the IPS signature checking process. For instance, "nds" typically indicates that a session has been identified but does not explicitly relate to IPS checks. "npu" is likely indicative of sessions that utilize certain processing units but is unrelated to the IPS functionality. Lastly, "log" is associated with logging traffic for audit or monitoring purposes rather than actively checking traffic against IPS signatures. Thus, "ndr" is the definitive flag that signifies IPS inspection of the traffic, marking it as critical for threat management.
