Keeping intrusion-detection and prevention engines, baselines, and signatures up to date supports which objective?

• A. Efficient and effective detection and prevention.
• B. Reduced hardware requirements.
• C. Automatic compliance without testing.
• D. Elimination of all vulnerabilities.

Answer: (A)

Staying current with intrusion-detection and prevention engines, baselines, and signatures keeps defense patterns aligned with the latest threats, which makes detection and prevention more efficient and effective. Signatures identify known attack methods; when they’re updated, newer exploits are recognized and blocked rather than slipping by. Baselines define normal behavior, so updates help the system spot anomalies sooner and with fewer false alarms. Together, timely updates improve how accurately the system detects threats and how reliably it prevents them, maximizing overall protection. The other outcomes aren’t guaranteed by updates alone. Updates don’t inherently reduce hardware needs, as processing power and memory requirements depend on the system design. Automatic compliance without testing isn’t realistic because ongoing validation is still required. And you can’t eliminate all vulnerabilities just by updates—new flaws and attack techniques continually emerge.
