A(n) analyzes traffic patterns and compares them to known patterns of malicious behavior. a. Intrusion prevention system b. intrusion detection system c. defense-in-depth strategy d. quantitative risk assessment

b. intrusion detection system

Explanation:

An intrusion detection system (IDS)  helps to  alert  service administrators   to detect suspicious or malicious activity  by monitoring and analyzing  specific patterns to network traffic. Most times, the IDS may be configured  to  respond to suspicious malicious traffic by  blocking the cyber attacker making  such IP address unable to access that particular  network.

An intrusion detection system (IDS)  can be either a Host Based Intrusion Detection Systems (HIDS) or a Network Based Intrusion Detection Systems (NIDS) depending on preference by the user.

It is therefore necessary for  businesses who require high level of security   to adopt good and effective  intrusion detection systems so  that the communication of information from businesses to businesses  can be safeguarded and secure from cyber attacks.
