CISSP – Information Systems Security Management Professional (ISSMP) — Question 24

Which of the following is the best method to stop vulnerability attacks on a Web server?

Answer options

• A. Using strong passwords
• B. Configuring a firewall
• C. Implementing the latest virus scanner
• D. Installing service packs and updates

Correct answer: D

Explanation

Installing service packs and updates is crucial as they often contain patches for known vulnerabilities, thus directly addressing potential security flaws. While strong passwords, firewalls, and virus scanners enhance security, they do not specifically fix vulnerabilities in the software, making them less effective against targeted attacks.
