Security Remediation Guides
CloudSploit Security Remediation Guides
CloudSploit's remediation guides are intended to be an open-source resource for improving cloud security. Many cloud IaaS providers like AWS, Azure, and Google Cloud have a shared responsibility model. They provide the physical and architectural security, along with tools to properly secure the services they offer, but it is up to the user to configure those settings properly.
Background
This repository is an extension of CloudSploit's open-source scanning engine. We first released the scanning engine in 2015, and this documentation repository is a natural follow up to that tool. The goal of these guides are to provide detailed steps on remediation common security issues in cloud services.
