Identification
Access control is an integral part of an organisation’s security system. It helps prevent unauthorised access to confidential data, physical resources, and operations. Access control is achieved through a three-pronged approach: identification, authentication, and authorisation. This article will discuss each of these elements in more detail.
Identification involves recognising an individual before providing access to a protected resource. It is the first step in access control and is usually done by verifying information about the person, such as their name, date of birth, and address. The most common form of identification is through an identification card, such as a driver's license or passport. Some organisations may also use biometric identification methods, such as facial recognition or fingerprinting, for higher levels of security.
Authentication
After the person has been identified, authentication is used to verify that the individual is who they claim to be. This often involves the user entering a unique password or token to validate their identity. In some cases, two-factor authentication may be used, where a second form of authentication, such as a one-time pin sent to the user’s mobile phone, is required. Authentication is an important element in access control as it ensures that only the authorised user is able to gain access.

Once a person has been identified and authenticated, authorisation allows them access to the appropriate resources. This is usually done through the use of roles, permissions, and groups. For example, an employee may have access to certain files, while another employee may be able to edit those files. Authorisation allows organisations to restrict which areas of their network a user can access, ensuring that confidential information is not exposed.
What are the challenges of access control?
Access control is not without its challenges. One of the biggest challenges is that it can be difficult to manage users with different levels of access. For example, some users may need to access sensitive information, while others may only need basic access. It is important to ensure that every user is given the right amount of access to ensure the security of the organisation’s data.
Another challenge is keeping up with changes in technology. As new technologies are developed, access control protocols must be updated to ensure that security remains tight. It is important to stay abreast of the latest advancements in access control to ensure that the system remains secure.
How can you implement access control?
Implementing access control is a relatively straightforward process. The process typically involves creating a user database, assigning roles and permissions to users, and setting up authentication protocols. It is important to ensure that all users are properly set up and that authentication protocols are regularly updated.
Organisations should also create a policy for access control that outlines how the system is to be used and what types of access are permitted. This policy should be reviewed regularly to ensure that the system is up-to-date and that there is no unauthorised access.
In summary, access control is an integral part of any security system and relies on the use of identification, authentication, and authorisation to keep networks secure. Implementing access control involves creating a user database, assigning roles and permissions, and setting up authentication protocols. There are a number of challenges associated with access control, but with the right policies and procedures in place, organisations can rest assured that their data is safe from unauthorised access.
