Short Overview of Access Control Systems

For many businesses, ensuring that only authorized personnel gain access to certain areas of the campus is important for security and safety reasons. Access control systems enable businesses to control who has access to a particular area or resource, which is critical for maintaining security and protecting valuable assets.

Whether you’re a small business owner or a facilities manager looking to upgrade your security, this post will give you the foundation you need to understand access control systems and make informed decisions about your security needs.

What Are Access Control Systems?

Access control systems are security measures that are put in place to restrict entry into certain areas. This can be accomplished in many ways, but the goal is always to authenticate the identity of those trying to enter before allowing them in. In addition to restricting entry, access control systems can also record who has accessed the area and when, to provide a useful method to maintain safety and security.

Why Use Access Control Systems?

There are numerous benefits to using an access control system, such as:

  • Enhanced security – Access control systems restrict access to only authorized individuals, preventing theft and other security breaches.
  • Improved safety – Dangerous areas can be protected so unauthorized people don’t gain access and cause harm to themselves or the contents of the area.
  • Increased accountability – By recording who accessed an area at a given time, it’s easier to track down the culprit should someone do something that they shouldn’t.
  • Remote access – Some systems allow administrators to control them remotely, making it easy to monitor and control who is entering the area.

Types of Access Control

Both physical and logical access control systems can be broken down into the ways in which they restrict access. The most common options are:

  • Mandatory access control (MAC) – These systems are based entirely on a set of predefined rules. The administrator will tell the system to grant access to someone based on their clearance level. Users have no control over the access process. These are commonly used in government applications.
  • Role-based access control (RBAC) – This type of system is similar to a MAC, except access is granted based on the assigned role of an individual instead of their clearance level. Companies often use this type of access control to restrict information to only those whose job requires it.
  • Rule-based access control – These systems are a little more flexible than the previous. They grant access based on a set of pre-defined rules. The rules could grant access based on time of day, location, identity, or any combination of those and other contextual factors.
  • Attribute-based access control (ABAC) – Even greater flexibility is allowed with this type of system. It grants access based on a custom set of rules that can be based on user attributes, environmental factors, and more. The result is more granular control over who is allowed access.
