What systems monitor the network and report security issues?

1. CloudShield

2. Intrusion prevention system

3. Firewall

4. Intrusion detection system

The correct answer is: Intrusion detection system

The correct choice is the Intrusion Detection System (IDS) because it is specifically designed to monitor network traffic and identify potential security threats or violations. An IDS analyzes the incoming and outgoing network packets to detect patterns that may indicate unauthorized access or suspicious activities. Once it identifies these anomalies, it can alert administrators or security personnel, enabling them to respond promptly to potential incidents. In contrast, while the Intrusion Prevention System (IPS) is also involved in network security, its primary function is to actively block or prevent detected threats, rather than just monitoring and reporting them. The role of a firewall is to control incoming and outgoing network traffic based on predetermined security rules but it does not have the specific capability to monitor for evidence of breaches or exploits in the same manner as an IDS does. CloudShield may refer to specific cloud security products or features that can include various protective mechanisms but is not a recognized standard system for monitoring security issues like the IDS.
