How to make your building safe through access control system

4th Aug 2023

Access control system is one of the most important aspects of a building or data security since it determines who is authorised to access and make use of the information and resources of a firm. Policies governing access control ensure that users are who they claim to be and that they have the right level of authorisation to access the company’s building or the data by utilising authentication and authorization procedures. It can also be used to limit physical access to campuses, buildings, rooms, and datacenters.

Understanding Access Control System

Access control is the practise of limiting entry to a piece of property, a building, or a room to just those individuals who have been granted permission to do so. A human being (a guard, bouncer, or receptionist, for example), a mechanical device (such as locks and keys), or a technical device (such as an access control system) are all viable options for implementing some form of physical access control. Within these types of situations, the use of physical key management may also be implemented as a means of further managing and monitoring access to mechanically keyed areas or access to particular tiny assets. This may be the case if the assets in question are quite small. Who, where, and when regulate physical access. An access control system controls who can enter and exit, where, and when. Keys and locks did this historically. Depending on the lock, only a key can unlock a door. Mechanical locks and keys do not allow time or date restrictions. Mechanical locks and keys are easy to copy and can’t track which key was used on which door. Rekeying locks is necessary when a mechanical key is lost or the key holder is no longer authorised to use the protected area.


Computers in electronic access control (EAC) systems circumvent the drawbacks of traditional lock-and-key systems. Mechanical keys can be replaced with a variety of credentials. When the proper identification is shown, the Electronic Access Control system releases the door. The door is left unlocked for a set amount of time once access is given, and the event is logged. When entry is denied, the door stays locked and a log of the attempt is made. Alarms will sound if the door is pushed open or left ajar for too long after being unlocked. The credential’s information, typically a number, is transmitted from the reader to the door access control system , a highly dependable processor, when the credential is presented. The access control security unit verifies the credential number against an authorization list, approves or declines the request, and updates a database with the details. The door acces will stay locked if entry is not permitted by the access security. The control panel triggers a relay that opens the door if the credential presented matches the one on file. A door open signal is likewise disregarded by the control panel so as not to trigger an alert. When access is denied, a red LED flashes, and when access is given, a green LED flashes, providing response from the reader.


  • An Access Control Panel
  • An Access-Controlled Entry such as door, turnstile, parking gate, elevator, or other physical barrier
  • A reader installed near the entry
  • Locking Hardware like electronic door strikes and electromagnetic locks
  • RTE buttons or motion detectors temporarily disable the door alarm while the door is opened. Mechanical free egress is exiting a door without electrically unlocking it. Important safety feature. The request-to-exit device unlocks the door when the lock must be electrically unlocked.

    Access control system are responsible for identifying a person or entity, confirming that the person or application in question is who or what it claims to be, and authorising the access level and set of actions that are connected with a username or IP address. Directory services and protocols, such as Lightweight Directory Access Protocol and Security Assertion Markup Language, are what provide access control security for authenticating and authorising users and entities, as well as enabling users and entities to connect to computer resources like distributed applications and web servers. These access controls are provided by directory services and protocols. Access control models are utilised by companies on the basis of the compliance standards that must be met as well as the amount of information technology (IT) security that must be maintained.

  • Discretionary Access Control (DAC)
  • Mandatory Access Control (MAC)
  • Role-Based Access Control (RBAC)
  • Rule-Based Access Control

  • Discretionary Access Control

    he firm owner can limit access to a site with a discretionary access control system (DAC). Each access control point lists authorised users. The system verifies each keycard swipe, PIN punch, or fingerprint scan against the list and grants or refuses access based on the previously determined allowances.
    The most versatile and accommodating access control solution is DAC. It’s the most versatile, but required access control methods are more secure. Since one person controls the system, they may give access to an unauthorised user. Companies that value simplicity and flexibility should adopt discretionary access control solutions.


    Mandatory access control systems (MAC) are the safest. Only owners and custodians can access the systems. The system administrator controls all access control settings. Unlike DAC systems, MAC systems identify people and provide them access to areas based on their programming. 150 employees require 150 system user permissions. Mandatory access control solutions are the most secure and inflexible. Administrators must reprogram user access, not just security lists, to modify permissions. High-security companies and agencies utilise MAC systems.


    RBAC is becoming the most prevalent access control method. RBAC systems grant permissions to job titles instead of users like MAC systems. It speeds up user access setup. If you have 10 salespeople, two managers, and three accountants, you don’t need 15 system security profiles. Three job titles would suffice. Just provide promoted personnel the right credentials.


    Rule-based access control (RBAC) is often used as an add-on to existing access control methods. Rule-based access control can also adjust permissions based on the administrator’s policies. If your business closes at 7 p.m., no one needs access to the main office, even management. Rule-based access control lets you bar everyone from 7 p.m. to 9 a.m. Any event can have rules.


    Though there are numerous benefits associated with installing Access control system, the following benefits are mentioned below:

  • Increase Ease Of Access For Employees
  • Getting Rid of Traditional Keys
  • Save Money and Energy
  • Keep track of who comes and goes
  • Protection against unwanted visitors
  • Prevent against data breach
  • Reduce thefts and accidents
  • Provide access to multiple buildings and locations
