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