ℹ️ Check
By default, when you change a rule-based policy such as access rules, the changes become effective immediately. With transactional model configured, the rules are not active until after compilation. Review the ASA configuration and verify that the following command is not configured. asp rule-engine transactional-commit access-group If transactional-commit access-group has been configured, this is a finding.
