What is Physical Security Information Management?

Physical security of an information management system assures security by implementing protective controls to a location that hosts your most confidential data. For example, when you access data centers physically to access servers, storage, routers, switches, etc. Similarly, when you are accessing the location (warehouse, IT department, finance or HR department) with malicious intentions to discover the possibility of a targeted attack which could be by inserting the infected USB drive, stealing confidential documents, taking pictures, finding the ways to access the data centers from elevators to the reception to the data center. ISO27001:2013 explains in detail what protective controls must be there to ensure physical security like access cards, port security, identification, CCTV, Biometrics, preventing WIFI access outside the location, fire alarm system, assembly points, etc.
