In the acronym CIA, what does the "I" stand for in network security?

In the context of network security, the "I" in the acronym CIA stands for Integrity. Integrity refers to the accuracy and reliability of data throughout its lifecycle. It ensures that information is not altered, deleted, or falsified either maliciously or inadvertently, thus maintaining the trustworthiness of the data.

When integrity is upheld, users can be confident that the data they are accessing has not been compromised. Techniques like checksums, hashing, and digital signatures are commonly employed to verify data integrity. This is critical in network security because any unauthorized modifications to data can lead to significant vulnerabilities and risks.

Understanding integrity is vital for anyone working in network security, as it plays a key role in safeguarding sensitive information and maintaining compliance with various regulations.
