Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) — Question 11

Which utility blocks a host portscan?

Answer options

• A. HIDS
• B. sandboxing
• C. host-based firewall
• D. antimalware

Correct answer: C

Explanation

The host-based firewall is designed to monitor and control incoming and outgoing network traffic, effectively blocking unauthorized port scans. HIDS and antimalware do not specifically focus on blocking port scans, while sandboxing is more about isolating applications rather than protecting against network scans.
