What does the integrity principle entail?

The integrity principle is a key component of information security and focuses on the accuracy and reliability of data. It ensures that information remains consistent, accurate, and trustworthy throughout its lifecycle. This principle protects data from unauthorized modification or destruction, thereby safeguarding its authenticity.

Choosing the option that describes the integrity principle highlights the need for measures to confirm that data is not altered by unauthorized individuals and maintains its intended meaning. This is vital in various contexts, such as maintaining the integrity of financial records, medical data, and personal information.

The other aspects, such as availability and backup, are essential elements of information security but belong to different principles. Availability pertains to ensuring that information is accessible when needed, while regular backups relate to recovery and data preservation strategies. Hence, those options do not specifically address the concept of integrity, which centers more on the accuracy and reliability of the information.
