Which of the following are its characteristics?

• A.Unable to detect malicious operations or mis-operations from insiders.
• B.Cannot perform in-depth inspection
• C.IDS can be linked with firewalls and switches to become a powerful "helper" for firewalls to better and more precisely control access between domains.
• D.Malicious code that is doped in allowable application data streams cannot be correctly analyzed.

About firewalls and IDS, which of the following is true?

• A.Firewall is unable to detect insider malicious operation or misoperation
• B.IDS can't interact with the firewall
• C.Firewall is a bypass device for fine-grained detection
• D.IDS is a straight-path device and can't perform depth detection

Which of the following statement is wrong about a network intrusion detection system (NIDS)?

• B.Use newly received network packets as a data source;
• C.Mainly used for real-time monitoring of critical network path information, listening to all packets on the network, collecting data, and analyzing suspicious objects
• D.Used to monitor network traffic and can be deployed independently.

Misuse detection discovers intrusion activity in system by detecting similar behaviors of user intrusions, or by detecting violations of system security rules indirectly by exploiting system flaws.
Which of the following is not misuse detection feature?
