Question 8

IPS is the best solution for protecting against inbound malicious traffic.

An Intrusion Prevention System (IPS) provides automated protection by actively monitoring network traffic and taking immediate action to block malicious activity, making it the ideal choice for the security manager's needs.

A) UEM

Unified Endpoint Management (UEM) focuses on managing endpoint devices within an organization, ensuring security and compliance. While UEM is important for device management, it does not specifically address the immediate action required to protect against inbound malicious traffic.

B) IPS

An Intrusion Prevention System (IPS) is designed to detect and prevent potential threats in real time by analyzing network traffic patterns. By automatically blocking malicious traffic, it effectively safeguards the organization against external attacks, making it the best solution for the security manager's requirements.

C) WAF

A Web Application Firewall (WAF) is primarily used to protect web applications by filtering and monitoring HTTP traffic. Although it can mitigate certain types of attacks, such as SQL injection and cross-site scripting, it does not provide the comprehensive network-level protection or the immediate response capability that an IPS offers.

D) VPN

A Virtual Private Network (VPN) secures internet connections by encrypting data and providing a private network for users. While it enhances privacy and security for remote users, it does not directly protect against inbound malicious traffic or actively block threats in real time.

Conclusion

The Intrusion Prevention System (IPS) stands out as the most effective solution for the security manager's need for automated and immediate protection against malicious traffic. Other options, such as UEM, WAF, and VPN, while valuable in their own contexts, do not provide the same level of proactive threat prevention that an IPS delivers. Therefore, IPS is the clear choice for ensuring robust security against external attacks.
