7.2.3: Default Deny-All Setting
Confirm that access control systems have a default "deny-all" setting


A default "deny-all" setting ensures no one is granted access until and unless a rule is established specifically granting such access. Some access control systems are set by default to "allow-all," thereby permitting access unless/until a rule is written to specifically deny it, and this violates this PCI requirement.

This Action1 query confirms that all access control systems used on the endpoints are effectively configured to deny all access unless it is granted specifically or otherwise flags systems that not configured properly to detect any violations of this section of PCI DSS.

Sign-up for Action1 Free Edition to install/uninstall software and patches, receive real-time alerts and view instant data from your endpoints, or run live or scheduled queries with the ability to export to CSV or Excel. Action1 Endpoint Security Platform is entirely SaaS, with online web interface (no management tools to install) and it has zero cost for basic functionality. Running in the Cloud, Action1 discovers all of your endpoints in seconds and you can query your entire network in plain English.
