8.3 Information Access Restriction

Access to information and other associated assets should be restricted in accordance with the established topic-specific policy on access control.

Information access restriction in information security refers to the process of limiting or controlling access to sensitive or confidential information on a network or system.

The goal is to ensure that only authorised individuals or systems can access the information and that the information remains secure and confidential.This can be done by implementing a variety of security controls, such as:

• Access controls: Implementing authentication and authorization mechanisms, such as user IDs and passwords, to ensure that only authorised individuals can access the information.
• Data encryption: Encrypting the information to protect it from unauthorised access in the event that it is stolen or intercepted.
• Data classification: Classifying the information based on its sensitivity and implementing different levels of protection accordingly.
• Data Leakage Prevention (DLP): Implementing DLP solutions to monitor and control the flow of sensitive data, both in and out of the organisation.
It is important to note that information access restriction is a continuous process and requires regular review and maintenance to ensure that the controls remain effective. Additionally, it is important to implement a least privilege principle, which ensures that individuals only have access to the information and resources necessary for them to perform their job. This helps in reducing the risk of accidental or intentional misuse of information.
