The correct answer is A. Integrity.
Integrity refers to the assurance that data has not been tampered with or modified, intentionally or unintentionally, without proper authorization. Maintaining data integrity ensures that the information is accurate, reliable, and trustworthy.
Data integrity can be compromised in several ways, including human error, technical malfunction, hacking, or malware attacks. It can be challenging to identify data tampering, particularly if the changes are subtle or minor. For instance, data may be altered by inserting, deleting, or modifying some of its components.
To ensure data integrity, organizations can use various measures, such as access controls, authentication, encryption, backups, and audits. Access controls limit who can view, edit, or delete data, while authentication verifies the identity of the user before granting access. Encryption protects data from unauthorized access, while backups enable organizations to restore data in case of loss or corruption.
Audits involve reviewing and analyzing the data logs and other records to detect any unauthorized access or modification attempts. Audits can also identify vulnerabilities and weaknesses in the security system, helping organizations to improve their security posture.
In conclusion, ensuring data integrity is crucial for maintaining the accuracy, reliability, and trustworthiness of the information. Organizations can implement various measures, such as access controls, authentication, encryption, backups, and audits, to protect data integrity from unintentional or malicious modification.
