Which action is a recommended cybersecurity practice?

• A. Use weak passwords
• B. Ignore security warnings
• C. Do not back up data
• D. Install security updates

Answer: (D)

Installing security updates is a key cybersecurity practice because software vendors release patches to fix vulnerabilities that attackers could exploit. When you apply updates, you close security gaps, reducing the chance of malware infection, data theft, or system compromise. Updates can also fix bugs that could be leveraged in attacks and may improve security features overall. To stay protected, keep devices set to receive automatic updates when possible and test updates on important systems before wide deployment. The other options leave openings for attackers: weak passwords can be cracked, ignoring warnings leaves you exposed to known threats, and not backing up data risks losing information if something goes wrong. Keeping software up to date is one of the most important protective steps.
