Integrity

What is Integrity?

Integrity is the property of safeguarding the accuracy and completeness of information and assets. It means that information has not been altered, corrupted, or destroyed in an unauthorised manner. Maintaining integrity ensures that information is trustworthy and reliable.

Examples of Threats to Integrity

• Malicious Attacks: A hacker altering financial records to commit fraud.
• System Errors: A software bug corrupting data during a file transfer.
• Unintentional Actions: An employee accidentally deleting an important document.

ISO 27001 Context

Integrity is one of the three core principles of information security, often referred to as the CIA Triad (Confidentiality, Integrity, and Availability). Protecting integrity is a key focus of ISO 27001, as an organisation cannot make sound decisions if its information is not accurate.
