How does an organization ensure CIA triad of access control systems?

The information technology infrastructure of any company must include access control systems. They are in charge of making sure that only people with the proper authorization can access sensitive information or carry out particular tasks. Organizations must adopt a comprehensive set of measures that address each of these concepts in order to guarantee the integrity, confidentiality, and availability of access control systems.

Integrity

Implementing a strong authentication method is one way to guarantee the integrity of access control systems. Multi-factor authentication, password rules, and biometric identification are a few examples of this. To access a system, for instance, a company might require users to input a special password and a one-time code that was sent to their email or mobile device. With this strategy, the system is protected from unauthorized users and access is given only after identity verification.

Confidentiality

To ensure the confidentiality of access control systems, organizations should implement strict access controls that limit access to sensitive information to only authorized individuals. This can include role-based access control, where users are granted access based on their job responsibilities, and data classification, where sensitive data is classified and access is restricted based on the level of sensitivity. For example, an organization can limit access to its financial system to only authorized finance personnel, and further restrict access to sensitive financial data within the system based on the user's role and clearance.

Availability

Finally, to ensure the availability of access control systems, organizations should implement measures that protect against system failures and downtime. This can include redundancy, backup systems, and disaster recovery planning. For example, an organization can implement redundant servers, backup power supplies, and off-site backups to ensure that access control systems remain available in the event of a system failure or disaster.

Organizations must implement a comprehensive set of measures to ensure the integrity, confidentiality, and availability of access control systems. These measures should include robust authentication mechanisms, strict access controls, and measures to protect against system failures and downtime. By implementing these measures, organizations can ensure that only authorized individuals can access sensitive information, and that access is available when needed, without any compromise to the integrity or confidentiality of the information.
