Confidentiality, Integrity, and Availability, called the triad, is a model designed to guide policies for data security within an organization. The model is also sometimes called the AIC triad (availability, integrity, and confidentiality) to avoid confusion with the CIA. Although components of the triad are 3 of the foremost foundational and crucial cybersecurity wants, cybersecurity experts, believe the CIA triad needs to be upgraded to remain effective.
In this context, confidentiality could be a set of rules that limits access to data, integrity is the assurance that the data is trustworthy and correct, and availability could be a guarantee of reliable access to the data by authorized personnel.
The following is a breakdown of the 3 key concepts:
- Confidentiality measures are designed to prevent sensitive data from unauthorized access. It's common for information to be categorized according to the quantity and damage that would be done if it fell into the wrong hands.
- Integrity involves maintaining the consistency, accuracy, and trustworthiness of information over its entire lifecycle. Information should not be modified in transit, and steps should be taken to ensure information can't be altered by unauthorized individuals (for example, during a breach of confidentiality).
- Availability suggests that data ought to be systematically and promptly accessible to authorized persons. This involves properly maintaining hardware and technical infrastructure and systems that hold and display the data.
Other Key Concepts:
- When we talk about authenticity, we're talking about the quality that ensures that communication, a document, or other data is genuine or unaltered. Confirming the legitimacy of a user is the main function of authentication. Controls such as data, transactions, communications, and documents.
- In order to ensure that neither the sender nor the recipient of a message may subsequently dispute sending it or receiving it, non-repudiation is used. To guarantee non-repudiation, people and organizations install digital signatures.
Best practices for implementing the CIA triad
Confidentiality
- Data should be handled to support the organization's needed privacy.
- Data should be encrypted using 2 Factor Authentication.
- Keep access management lists and different file permissions up to this point.
Integrity
- Ensure employees are experienced in compliance and regulatory needs to minimize human error.
- Use backup and recovery software applications
- To ensure integrity, use version control, access control, security control, information logs, and checksums.
Availability
- Use preventive measures like redundancy, failover, and RAID. guarantee systems and applications keep updated.
- Use network or server monitoring systems.
- Ensure a data recovery and business continuity (BC) setup is in place of data loss.
