The first pillar, Confidentiality, emphasizes the need to restrict access to information to only authorized individuals or systems. Through encryption, access controls, and data classification, confidentiality measures prevent unauthorized viewing or disclosure of sensitive data.

​

Integrity, the second pillar, focuses on maintaining the accuracy and reliability of data. It ensures that information is not improperly altered or tampered with, using methods such as data validation, checksums, and digital signatures to detect and prevent unauthorized modifications.
 

Availability, the third pillar, ensures that information and systems are accessible and usable when needed. This involves implementing backups, redundancy, fault tolerance, and disaster recovery plans to minimize downtime and ensure continuity of operations.

Authenticity, the fourth pillar, verifies the validity of users and systems. By requiring authentication through methods like passwords, biometrics, and digital certificates, organizations can ensure that only legitimate users have access to resources.

Finally, the fifth pillar, Non-Repudiation, prevents individuals from denying their actions in a transaction. Techniques such as digital signatures and audit trails establish accountability and provide evidence of actions taken, ensuring that transactions are verifiable and attributable.

Five Tattva recognizes that these five pillars are interconnected and mutually reinforcing. Strengthening one pillar inherently enhances the others, creating a comprehensive and robust Infosec framework. By focusing on these foundational principles, organizations can better protect their information assets, mitigate risks, and maintain trust with stakeholders.
