What is CIA Triad

In Cybersecurity, “CIA” is the first and foremost concept and basic core foundation of information security and CIA stand for Confidentiality, Integrity, and Availability. A basic principle of this foundation is to guide the user or client in planning, executing, and supervision of security measures to protect their digital assets and invaluable data. Each and every phase is important for users to secure their data from risks.

Confidentiality

• It ensures that sensitive and valuable information is available only to authorized individuals or entities.
• Its procedures are placed in such a way that it will stop illegal access, exposures of data to unwanted entities and leakage of information to unwanted people.
• It uses different techniques such as encryption, access controls, and user authentication to help maintain confidentiality.

Integrity

• The focus of integrity is mainly on the accuracy of the data which is not alert by anyone without owner’s permission or approval, consistency, and trustworthiness of data and invaluable information.
• It makes sure that data remains unchanged, unaltered and trustworthy throughout its lifecycle.
• Basically data integrity, mechanisms like checksums, digital signatures, and data validation are implemented to detect and prevent unauthorized modifications.

Availability

• Availability makes sure that information and resources are available throughout the process and usable by authorized users whenever needed.
• This principle aims to prevent disruptions or outages that could lead to downtime and loss of productivity.
• Measures such as redundancy, backup systems, and disaster recovery plans help ensure the high availability of critical systems and services.

The CIA triad serves as a fundamental framework for evaluating and implementing security controls, policies, and practices in various technology environments, including networks, systems, applications, and data storage. Organizations strive to balance these three principles to create a secure and resilient cybersecurity posture.
