An access control system for security at your front door or all your doors can protect your information and equipment, as well as your employees, and customers or patrons. There are many types of access control systems, and the kind you choose will depend on the size, scope and type of business you have, and what you want to accomplish. For instance, you can do the following:

  • Prevent theft of equipment by knowing who is in the building, and when.
  • Track employees so you know if they’re showing up for work, or if someone is in the building when they shouldn’t be.
  • Prevent access to areas where software or hardware with sensitive information on it is stored.
  • Do away with the need to track keys. You no longer have to worry about the return of keys, or the cost involved with getting new ones.
  • Reduce accidents by allowing access to certain equipment or hazardous areas only to those who are trained or qualified to work in these areas.

Access control also identifies and authenticates someone with a specific job. That individual is then allowed only a key to the area they are authorized to access and no more.

Types of Access Control

There are, generally speaking, three types of access control systems:

  • Role-based Access Control – Rather than assigning individuals access, a system administrator assigns access based on job titles.
  • Mandatory Access Control – This system is more common for organizations needing a high level of confidentiality, such as military institutions. These systems enforce control by a process of subject clearance and objects labels, such as confidential, secret and top secret. Subjects may access objects only if their clearance is equal to or more than the label of the object. These systems are expensive and difficult to control.
  • Discretionary Access Control – Business owner decides who is allowed in certain locations (physically or digitally). This is the least restrictive system.

In general, small businesses choose DAC systems as the most appropriate.
