Explanation
Integrity is focused on the trustworthiness of data as well as the prevention of unauthorized modification or tampering of it. A prime consideration for maintaining integrity is an emphasis on the change management and configuration management aspects of operations, so that all modifications are predictable, tracked, logged, and verified, whether they are performed by actual human users or systems processes and scripts.

Explanation:
No matter what kind of application, system, or hosting model used, encryption is 100 percent dependent on encryption keys. Properly securing the keys and the exchange of them is the biggest and most important challenge of encryption systems.

Explanation:
Sensitive data exposure occurs when information is not properly secured through encryption and secure transport mechanisms; it can quickly become an easy and broad method for attackers to compromise information. Web applications must enforce strong encryption and security controls on the application side, but secure methods of communications with browsers or other clients used to access the information are also required. Security misconfiguration occurs when applications and systems are not properly configured for security, often a result of misapplied or inadequate baselines. Insecure direct object references occur when code references aspects of the infrastructure, especially internal or private systems, and an attacker can use that knowledge to glean more information about the infrastructure. Unvalidated redirects and forwards occur when an application has functions to forward users to other sites, and these functions are not properly secured to validate the data and redirect requests, thus allowing spoofing for malware or phishing attacks.

AES is an encryption standard. Link encryption is a method for protecting communications traffic. One-time pads are an encryption method.
