STIGQter: STIG Summary: Infrastructure L3 Switch Security Technical Implementation Guide Version: 8 Release: 29 Benchmark Date: 25 Jan 2019: The IAO will ensure the Server Farm infrastructure is secured by ACLs on VLAN interfaces that restrict data originating from one server farm segment destined to another server farm segment.SV-20062r1_rule

ACLs do not protect against compromised servers

Review the filter and ensure access from other server segments is denied unless necessary for application operation. The intent of the policy should be to protect servers from a server that has been compromised by an intruder.
Review the firewall protecting the server farm. Vlan configurations should have a filter that secures the servers located on the vlan segment. Identify the source ip addresses that have access to the servers and verify the privilege intended with the SA. The filter should be in a deny by default posture.
If the filter is not defined on the firewall and the architecture contains a layer 3 switch between the firewall and the server, than review the VLAN definition on the L3 switch.
