Real-World Scenario: A company delayed installing a critical security update for their access control system. A hacker exploited a known vulnerability in the outdated software, gaining unauthorised access to the building and sensitive data. Regularly updating your software and firmware is crucial to prevent such incidents.
3. Test System Functionality
Regularly testing your access control system is essential to ensure it functions correctly and reliably. This includes testing all aspects of the system, from card readers and keypads to door locks and alarms.
Test All Access Points
Verify card reader functionality: Test all card readers to ensure they accurately read cards and grant access to authorised personnel. Check for any delays or errors in the reading process.
Test keypad functionality: Test all keypads to ensure they accurately accept codes and grant access to authorised personnel. Check for any issues with key responsiveness or code recognition.
Test door locks: Verify that all door locks engage and disengage properly. Check for any signs of wear or damage that could compromise their security.
Test Alarm System Integration
Trigger alarms: Test the integration between the access control system and the alarm system by triggering alarms under controlled conditions. Verify that the alarms are triggered correctly and that the appropriate personnel are notified.
Verify alarm response: Verify that the alarm response procedures are followed correctly. This includes dispatching security personnel, contacting law enforcement, and documenting the incident.
Test Emergency Procedures
Test emergency unlock: Test the emergency unlock functionality to ensure that doors can be unlocked quickly and easily in the event of an emergency.
Verify evacuation routes: Verify that evacuation routes are clearly marked and accessible. Ensure that all personnel are familiar with the evacuation procedures.
Common Mistake: Only testing the system after installation and neglecting ongoing testing. Access control systems can degrade over time due to wear and tear, environmental factors, or software glitches.
