Identity management is a part of the process of access control. In almost every post that a security officer is stationed, there will be some individuals that are supposed to have access to the property. The means of identifying if an individual is authorized is one of the more important parts of the security operation.
There are several ways to verify that an individual is supposed to have access to a particular area. Badges and ID cards are effective solutions, especially if they are hard to counterfeit. Uniforms with features specific to a department are another common feature that makes it very easy to quickly determine where the wearer should be. When the number of people allowed to enter a property is small, the security officer can be presented with a list to cross check against, or they can be informed in advance when to expect a visit to enable them to turn away all other arrivals.
If the physical access control is implemented with strict enough defenses paired with an identity checking procedure that is proven to be effective, personnel stationed inside can presume that anyone that has made it inside is authorized and can focus on other functions.
