• Misaligned/Worn *****: Over the course of thousands of open/close cycles, even commercial grade doors, hinges, frames, and closers sag or become worn over time. If left unchecked, doors may not fully close when opened or may take a long time to close, therefore allowing many people entrance from a single card read. A regular and discipline door maintenance schedule for access-controlled openings is critical to prevent the issue.

• Malicious ******: Preventing untrusted or dangerous people from entering an area is often the primary goal of access control. Often, readers and locks alone are not enough to mitigate this risk despite the occurrence being minor. To properly prevent undetected entry, often additional engineering controls like sensors, analytics, or even turnstiles are needed.
