What type of application security risk involves weak cryptographic methods and insecure storage of keys?

The correct response highlights the critical issue of weak cryptographic methods and the insecure storage of keys, which directly relate to how sensitive data is managed and protected. Sensitive Data Exposure refers to scenarios where sensitive information, such as passwords, credit card numbers, or personal data, is inadequately protected and can be easily accessed by unauthorized users. When cryptographic methods are weak or keys are not securely stored, it leaves the data vulnerable to theft or manipulation. Attackers can exploit these weaknesses to gain access to sensitive information, making it a significant security risk.

Understanding this concept is vital for ethical hackers and security professionals, as it emphasizes the need for robust encryption practices and secure key management to safeguard sensitive data effectively. While other options relate to different security concerns, they do not specifically encompass the risks associated with cryptographic failures, which are crucial for preventing sensitive data exposure.
