In some cases, common activities compromise existing physical security measures. For example, employees may leave file cabinets unlocked, fail to lock offices when not in them, leave information unsecured and available for others to view and take, hold secure doors open for other individuals (defeating physical security), allowing them to “tailgate” or follow a person through a secure portal without using their access control device, (& Vance, 2009) write passwords on documents or calendars and Post-it notes in offices, and fail to shut down or log off on workstations.
