If Virtual Routing and Forwarding (VRF) is used to segment traffic and force traffic to traverse through next generation firewalls with ACLs, this requirement is not applicable. Review the switch configuration to verify that ACLs are configured to allow or deny traffic for specific source and destination addresses as well as ports and protocols. For example, the configuration below will allow only printer traffic into subnet 10.1.12.0/24 and SQL traffic into subnet 10.1.13.0/24. ICMP is allowed for troubleshooting and OSPF is the routing protocol used within the network. interface GigabitEthernet0/1 no switchport ip address 10.2.1.1 255.255.255.252 ip access-group FILTER_SERVER_TRAFFIC in … … … ip access-list extended FILTER_SERVER_TRAFFIC permit tcp any 10.1.12.0 0.0.0.255 eq lpd 631 9100 permit tcp any 10.1.13.0 0.0.0.255 eq 1433 1434 4022 permit icmp any any permit ospf any any deny ip any any Alternate: Inter-VLAN routing interface Vlan12 ip address 10.1.12.1 255.255.255.0 ip access-group FILTER_PRINTER_VLAN out ! interface Vlan13 ip address 10.1.13.1 255.255.255.0 ip access-group FILTER_SQL_VLAN out … … … ip access-list extended FILTER_PRINTER_VLAN permit tcp any any eq lpd 631 9100 permit icmp any any deny ip any any ip access-list extended FILTER_SQL_VLAN permit tcp any any eq 1433 1434 4022 permit icmp any any deny ip any any If the switch is not configured to enforce approved authorizations for controlling the flow of information within the network based on organization-defined information flow control policies, this is a finding.

How these changes are found

Checks are matched across the two releases by V-number. A check counts as updated when DISA gave it a new rule revision (the r number in its SV-…_rule id) and its title, severity, check text, fix text, discussion, CCIs or other fields changed — the same comparison STIG Compare makes. Added checks are new V-numbers; removed checks are V-numbers V3R4 no longer has.
