Answer:b. intrusion detection system
Step-by-step 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.
