Question 26

To block incoming malicious traffic

The primary function is to block incoming malicious traffic, which is essential for maintaining the security and integrity of a network or system.

A) To encrypt the database files

While encrypting database files is an important security measure, it does not directly relate to the primary function of blocking malicious traffic. This option focuses more on data protection rather than network defense.

B) To monitor logs for unauthorized changes

Monitoring logs for unauthorized changes is a vital security practice that helps in identifying breaches after they occur. However, it is a reactive measure and does not serve the primary function of actively blocking incoming threats.

C) To establish VPN access

Establishing VPN access is crucial for secure remote connections, but it does not pertain to the function of blocking malicious traffic. This option addresses connectivity rather than threat prevention.

D) To block incoming malicious traffic

This is the correct answer, as the main role is to prevent unauthorized and potentially harmful traffic from entering the network, thereby safeguarding the system from attacks.

Conclusion

Blocking incoming malicious traffic is a proactive security measure that protects systems from threats before they can cause harm. Options A, B, and C, while important in their contexts, do not fulfill the primary function of actively defending against malicious traffic, making D the definitive choice.
