Security Hub score

After first-time score generation, Security Hub updates the security score every 24 hours. Security Hub displays a timestamp to indicate when a security score was last updated. Can you please check if the time stamp of score generation has changed?

Security score you see in the Security standards dash board is cloud security posture score. It is percentage of passed Compliance controls over enabled controls. If all the checks for the control are fixed and no failed checks for the control when the score is computed, then the score will change. Score is computed once every 24 hours. If you mitigated a finding that is from threat detection service such as GuardDuty, security score in the security hub summary screen will not change.
