Access Control

Access Control is a method to impose controls that permit or deny users access to network resources, usually based on a user’s account or some group to which the user belongs. It emphasizes laws and standards that enable people to responsibly regulate the information they are giving up.

This is a crucial element of data security that determines who has the access to the enterprise resources and information. Its rules ensure that users have proper access to company data by using authentication and authorization.

Physical access to campuses, buildings, rooms, and data centers can all be restricted via access control. This control system verifies numerous login credentials to identify users such as -  

  • User names 
  • Passwords 
  • Personal Identification Numbers (PIN)
  • Biometric scans 
  • Security tokens 

After finishing the authentication process, access systems allow the proper level of access and actions associated with that user's identification and IP address or deny the access. This security system prevents sensitive information like - customer data, personally identifiable information, intellectual property etc. from coming into the hands of the wrong people. 

Without a comprehensive access control plan in place, organizations may risk data loss from both internal and external sources.
