The city’s edge firewall has reached vendor end-of-life and will receive no further security patches, yet it still terminates Internet traffic for several departments. Which vulnerability concern is most accurate?
Select an answer to reveal the explanation.
Short Explanation
An EOL firewall still guarding the Internet edge is a legacy/unpatchable risk — known bugs will never get vendor fixes. That is not pretexting or XSS. Plan replacement or compensating controls before the next civic outage becomes a breach story.
Full Explanation
End-of-life and legacy systems are vulnerability concerns because vendors stop issuing patches while assets remain exposed. Objective 2.3 covers EOL/legacy alongside other vulnerability types. Pretexting, XSS, and unsecure wireless describe other issues. Municipal edge devices should have refresh cycles and documented compensating controls if temporary continued use is unavoidable.
