Explanation
Integrity ensures that data is not altered or tampered with by unauthorized users.
The security principle that ensures files cannot be modified without proper authorization is integrity.
Integrity in cybersecurity refers to the protection of data from unauthorized alteration, ensuring that information remains accurate, consistent, and trustworthy throughout its lifecycle.
Measures to maintain integrity include file permissions, user access controls, checksums, digital signatures, and version control systems. These controls prevent unauthorized users from making changes and help detect any accidental or intentional tampering.
Maintaining data integrity is critical for preventing data breaches, financial loss, and reputational damage, as unauthorized modifications can compromise the reliability and trustworthiness of information.
Integrity is a core component of the CIA triad (Confidentiality, Integrity, Availability), which forms the foundation of information security strategies.
Integrity ensures that data and files cannot be altered or tampered with by unauthorized users, maintaining the accuracy and reliability of information.
