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 Ethernet2/3 no switchport ip access-group FILTER_SERVER_TRAFFIC in ip address 10.1.23.2/24 no shutdown … … … ip access-list FILTER_SERVER_TRAFFIC 10 permit tcp any 10.1.12.0/24 eq lpd 20 permit tcp any 10.1.12.0/24 eq 631 30 permit tcp any 10.1.12.0/24 eq 9100 40 permit tcp any 10.1.13.0/24 eq 1433 50 permit tcp any 10.1.13.0/24 eq 1434 60 permit tcp any 10.1.13.0/24 eq 4022 70 permit icmp any any 80 permit ospf any any 90 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 FILTER_PRINTER_VLAN 10 permit tcp any any eq lpd 20 permit tcp any any eq 631 30 permit tcp any any eq 9100 40 permit icmp any any 50 deny ip any any ip access-list FILTER_SQL_VLAN 10 permit tcp any any eq 1433 20 permit tcp any any eq 1434 30 permit tcp any any eq 4033 40 permit icmp any any 50 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.
