Detecting and Marking Non-Compliant VPC Security Groups: SOC2 Compliance
There was a problem that the LLM was not able to address. Please rephrase your prompt and try again.
This task focuses on scrutinizing default security groups in AWS VPCs to identify and flag those allowing unauthorized traffic. It serves as a critical measure to pinpoint security groups that deviate from the no-traffic policy, ensuring adherence to stringent network security protocols in VPC environments.

Implementing No-Traffic Policy in VPC Default Security Groups
There was a problem that the LLM was not able to address. Please rephrase your prompt and try again.This task involves configuring the default security groups within AWS VPCs to strictly enforce a no-traffic policy. It entails systematically updating the security group rules to block all inbound and outbound traffic, ensuring compliance with stringent network security protocols.
