Enhancing Security with Access Control Systems: A Comprehensive Guide by Adeva Security

The increasing need for security in commercial and residential environments has led to the evolution of access control systems from traditional lock-and-key mechanisms to electronic security solutions. The shortcomings of conventional locks – easy to misplace, steal, and duplicate, paired with their inability to provide audit trails or be effectively managed – have underscored the importance of access control systems in today’s world.

Electronic access control solutions offer many benefits, notably in their ability to provide robust, customizable access restrictions. By using these electronic systems, security teams can devise unique access levels for different individuals or groups, enhancing control and flexibility over who gets access to what and when.

Access control systems become especially crucial in commercial environments where secure yet convenient access is required for many users – from employees and residents to visitors, package delivery personnel, and maintenance contractors. Access control measures implemented at building entrances help maintain security by facilitating easy access for authorized individuals while barring entry to unauthorized ones.

Moreover, these systems maintain security within a building by restricting access to sensitive areas. This could be server rooms in an office complex where confidential data is stored or amenities like gyms and mail rooms in a residential setting, accessible only to residents. Notably, the system logs every access event, providing valuable insights and evidence in case of an incident or dubious activity.

But how does an access control system function? An authorized user presents their credentials to an access control reader at the entrance. The reader sends this information to software that checks it against a database of authorized users. If valid and appropriate for the given door and time, the software triggers a signal to unlock the electronic lock, allowing access. If not, the door remains locked.

The heart of the access control system is the control panel or controller board. It dictates the fundamental functions of the system, including making access decisions and logging all access requests for future reference. Visitors might require temporary credentials like a visitor badge or digital guest pass. With access to the control mechanism, occupants or front desk personnel can initiate a door release signal to allow entry.

Security professionals or property managers should enforce access control policies to ensure the optimum level of security and access at entrances or restricted areas. There are five primary types of access control policies:

  1. Discretionary Access Control (DAC): The property owner or administrator defines who can access the building or specific area, offering basic security.
  2. Mandatory Access Control (MAC): Access rights are managed by security professionals and, based on multiple security clearance levels, are essential for highly secure areas.
  3. Attribute-based Access Control (ABAC): Access is granted based on attributes such as user type, location, department, and duties, reflecting the organization’s structure.
  4. Role-based Access Control (RBAC): Access is granted based on defined business roles rather than individual identities, giving users access to areas necessary for their organizational functions.
  5. Rule-based Access Control: The administrator defines Access rules based on conditions like time of day and location.


In summary, access control systems are indispensable for safeguarding commercial and residential environments, providing robust, customizable, and manageable security solutions.
