Free Tool: 1.2: Restrict Connections Between Untrusted Networks and CDE


Examination of desktop firewall configurations to verify that connections from untrusted networks to workstations in CDE are restricted









Action1 Customers

An "untrusted" network is a network that is external to the organization and outside of the organization's ability to control and manage. Action1 automates examination of desktop firewall configurations on every single endpoint within cardholder data environments. This helps to verify that connections between untrusted networks and endpoints with cardholder data are restricted on the endpoint connectivity level, as the last line of defense in case the network-level firewall mechanism fails to restrict such connections properly. Proper implementation of connection restrictions can help to prevent malicious individuals from accessing the organization's endpoints from external (untrusted) locations.
