A property of Information that has the ability to prove occurrence of a claimed event.

A property of information that has the ability to prove occurrence of a claimed event is integrity. Integrity is one of the three main objectives of information security, along with confidentiality and availability. Integrity ensures that information and systems are not corrupted, modified, or deleted by unauthorized actions or events. Integrity also implies that information and systems can be verified and validated as authentic and accurate. Electronic chain letters are not a property of information, but a type of spam or hoax message that may contain malicious or misleading content. Availability means that service should be accessible at the required time and usable only by the authorized entity. Accessibility is not a property of information, but a characteristic of usability that refers to how easy it is for users to access and interact with information and systems. References: : CQI & IRCA ISO 27001:2022 Lead Auditor Course Handbook, page 24. : [ISO/IEC 27001 Brochures | PECB], page 4. : [ISO/IEC 27001 LEAD AUDITOR - PECB], page 13.
