CertNexus Certified Cyber Secure Coder (CSC) — Question 2

A system administrator identifies unusual network traffic from outside the local network. Which of the following is the BEST method for mitigating the threat?

Answer options

• A. Malware scanning
• B. Port blocking
• C. Packet capturing
• D. Content filtering

Correct answer: B

Explanation

Port blocking is the best method for mitigating the threat as it can prevent unauthorized access by closing off specific ports that are being targeted. Malware scanning, packet capturing, and content filtering may help in identifying or analyzing the issue, but they do not actively stop the unusual network traffic as effectively as port blocking does.
