What does an intrusion detection system (IDS) do?

• A. It restricts access to sensitive data
• B. It monitors network traffic for suspicious activity and potential threats
• C. It encrypts data for secure transmission
• D. It optimizes data flow in a network

Answer: (B)

An intrusion detection system (IDS) is primarily designed to monitor network traffic and analyze it for any signs of suspicious activity or potential security threats. By continuously observing and assessing data packets flowing through the network, the IDS can identify patterns or anomalies that might indicate unauthorized access attempts, malware infections, or other malicious actions. When the IDS detects such activities, it generates alerts to notify administrators, allowing them to take action to mitigate potential threats. This capability is crucial for maintaining the security and integrity of a network. An IDS does not perform actions like restricting access, encrypting data, or optimizing data flow; its main function is focused on surveillance and threat detection within the network.
