Systems, methods, and apparatuses enable updating security policies in response to detecting attack activity or security threats. In an embodiment, security microservices detect attack activity sent between resources within an internal network. In response, the security microservices correlate the attack activity to externally accessible resources that were the initial entry point for the attack activity to the internal network. Based on this correlation, the security microservices update security policies bi-directionally to prevent the spread of future attack activity in the internal network between resources at a same level in the internal network and between resources at different levels in the internal network.
