Exam CISSP topic 1 question 413 discussion

D. The access token or assertion should be encrypted to ensure privacy. Encrypting the access token or assertion helps ensure the confidentiality and privacy of the data being transmitted. This is especially important when dealing with sensitive information, such as privileged access to systems or resources. Encryption ensures that only authorized parties can decrypt and access the data, protecting it from eavesdropping and unauthorized disclosure.

D. The access token or assertion should be encrypted to ensure privacy. To protect access to privileged information, it is important to ensure that the authorization mechanisms are secure and that sensitive data, such as OpenID Connect (OIDC) tokens or Security Assertion Markup Language (SAML) assertions, are not accessible to unauthorized users. Encryption is the best method to protect sensitive data, ensuring that it remains private and confidential. By encrypting the access token or assertion, only authorized parties with the appropriate decryption keys will be able to read and access the data. Passing data in a bearer assertion, only signed by the identity provider (option A) may be secure to some extent, but it does not provide the same level of confidentiality as encryption. Similarly, base64 encoding (option B) is not encryption, and the encoded data can be easily decoded by anyone with access to the encoding algorithm. Using a challenge and response mechanism (option C) may provide authentication, but it does not ensure the privacy and confidentiality of the data being transmitted. (chatGPT)
