CISSP study material · question 355 of 500
A resource server accepts JSON web tokens up to an hour past their expiry to accommodate clock differences between hosts. What does RFC 7519 permit?
Show the answer
Answer: B. Some small leeway, usually no more than a few minutes, for clock skew.
The moment of use must fall before the stated expiry, though a few minutes of tolerance for clocks that disagree is considered reasonable.
