Description
To prevent malicious or accidental leakage of information between test and development environments, organizations must implement a deny-by-default security posture. All traffic not explicitly permitted must be denied. Such rule sets prevent many malicious exploits or accidental leakage by regulating the ports, protocols, or services necessary between network segments within the test and development environment.

Check Text ( C-46817r1_chk )
Determine whether a deny-by-default security posture has been implemented for both ingress and egress traffic for the test and development environment. If the organization is not using a deny-by-default security posture for ingress and ingress traffic for the test and development environment, this is a finding.

Fix Text (F-44670r1_fix)
Implement a deny-by-default security posture for both ingress and egress traffic between network segments in the test and development environment.
