Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Verifying the audience (aud) claim
Validating the token signature and checking the audience claim are the two most critical steps to prevent token spoofing or replay attacks.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configuring the IdP to use weak hashing algorithms
Why it's wrong here
Weak algorithms compromise the integrity of the federation.
- ✓
Verifying the audience (aud) claim
Why this is correct
The audience claim confirms the token was intended for this specific SP.
- ✗
Allowing all claims to be processed without filtering
Why it's wrong here
Claims should be mapped and filtered to prevent injection/unauthorized attribute usage.
- ✓
Validating the signature of the assertion/token
Why this is correct
Without signature validation, the SP cannot confirm the token was issued by the trusted IdP.
- ✗
Ignoring timestamp validation to avoid clock skew
Why it's wrong here
Clock skew should be managed by setting an allowed drift window, not by ignoring timestamps.
