Terry installs a network-based intrusion detection system (IDS). What actions can he take on the traffic that flows through the IDS?

IDSs are capable of identifying malicious or unwanted traffic based on their detection rules and signatures, but they cannot prevent or modify traffic. On the other hand, an intrusion prevention system (IPS) that is deployed in-line with network traffic can take action on that traffic. As a result, IDSs are frequently employed when it is not feasible to block network traffic or when a tap or similar network device is employed to replicate traffic for examination.
