Access control

What is Access Control?

Access control is the selective restriction of access to a place or other resource. It is a fundamental component of data security that dictates who is allowed to access and use company information and resources. It operates through authentication and authorization, ensuring that each user is who they claim to be and that they have the appropriate access level for their needs.

Examples of Access Control

  • Discretionary (DAC): The digital equivalent of a personal invitation. The owner or administrator sets the access policies.
  • Mandatory (MAC): The high-security clearance approach, often seen in government or military environments, where access is regulated by a central authority.
  • Role-Based (RBAC): Access is granted based on the user's role within an organization, ensuring they only see what they need to perform their duties.
  • Attribute-Based (ABAC): A dynamic method where access is determined by user attributes and environmental conditions, like time of day or location.

The Importance of Multifactor Authentication (MFA)

MFA is a security system that requires more than one method of authentication from independent categories of credentials to verify the user's identity for a login or other transaction.

  1. Something the user knows (e.g., a password or PIN)
  2. Something the user has (e.g., a security token or mobile phone)
  3. Something the user is (e.g., biometric verification like fingerprints or facial recognition)

Access Control Implementation

  • Physical: Limits access to campuses, buildings, rooms, and physical IT assets.
  • Logical : Limits connections to computer networks, system files, and data.

The Role of IT Managers

IT Managers are tasked with the critical role of implementing and managing access systems. They ensure that these systems are robust, compliant, and capable of repelling unauthorized access attempts while facilitating a seamless workflow for authorized personnel.
