Question 56

IPS is the best security item to add for enhanced protection against network attacks.

An Intrusion Prevention System (IPS) is crucial for actively monitoring network traffic and preventing identified threats. This makes it an ideal addition to the organization's existing firewall, providing a more robust defense against ongoing attacks.

A) SIEM

A Security Information and Event Management (SIEM) system is beneficial for collecting and analyzing security data but does not directly prevent attacks in real-time. While it can provide insights and alerts about potential threats, it lacks the immediate response capabilities of an IPS.

B) Load balancer

A load balancer is designed to distribute network traffic efficiently across multiple servers to ensure optimal resource use and availability. However, it does not provide security features and therefore does not address the need for protection against active network attacks.

C) UTM

Unified Threat Management (UTM) solutions combine multiple security features, including firewall, antivirus, and intrusion detection. While it can enhance security, it may not specifically target the immediate threat scenario as effectively as an IPS that focuses on actively preventing intrusions.

D) IPS

An Intrusion Prevention System (IPS) is specifically designed to identify and prevent malicious activities in real-time. By analyzing network traffic and taking action against identified threats, an IPS significantly enhances the organization's security posture against ongoing attacks.

Conclusion

The IPS stands out as the most effective solution for defending against network attacks, as it not only identifies threats but also takes immediate action to prevent them. In contrast, the other options either lack direct prevention capabilities or do not specifically address the nature of the attacks the organization is experiencing. Therefore, adding an IPS will provide the necessary protection to safeguard the network effectively.
