CloudMapper
CloudMapper - A visualization and security monitoring tool for AWS environments, providing insights into access control policies and infrastructure. It is a tool for visualizing AWS environments and auditing for access control policies and security posture. https://github.com/duo-labs/cloudmapper
CloudMapper is an open-source tool designed for visualizing and analyzing AWS cloud environments, specifically focusing on network architecture and security. It helps users understand and assess the security posture of their AWS environments by generating interactive diagrams that map out the relationships between AWS resources such as VPCs, EC2 instances, S3 buckets, IAM roles, and security groups. The tool automatically discovers the configuration of an AWS environment and creates a visual representation that aids in identifying security risks and misconfigurations, making it easier for teams to review complex AWS infrastructures.
One of the primary functions of CloudMapper is to assist with the identification of unintended access, overly permissive security group rules, and exposed resources like open S3 buckets. By generating network diagrams, users can easily visualize how traffic flows between resources and spot potential vulnerabilities in security group configurations or other settings. This is especially valuable for security assessments, as it provides clear insights into how resources are interconnected and whether there are any unintended security holes that could be exploited.
CloudMapper also supports the visualization of AWS IAM roles and policies, which is crucial for understanding access controls within an organization’s cloud environment. By examining role and policy configurations, CloudMapper can help identify overly permissive permissions, unused roles, or misconfigured trust relationships that could pose a risk to the environment. The tool can be used to audit large, multi-account AWS environments, providing security teams with the insights they need to make informed decisions about resource access and security improvements.
Additionally, CloudMapper can be used in continuous security monitoring workflows, helping organizations to keep track of changes to their AWS infrastructure over time. By regularly generating updated visualizations and comparing them to previous assessments, security teams can quickly spot deviations in network architecture or security configurations. This helps ensure that infrastructure changes are not inadvertently introducing vulnerabilities. The ability to automate these reports also integrates seamlessly with broader security automation tools, improving the overall security management process.
Conclusion
CloudMapper is a powerful visualization tool for AWS environments, enabling users to map and analyze their cloud infrastructure with a focus on network security and IAM configurations. It simplifies the process of identifying security risks and misconfigurations by generating clear, interactive diagrams that show how resources are interconnected. As an open-source tool, it supports continuous security monitoring, making it a valuable asset for teams working to maintain secure and well-architected AWS environments. Through its intuitive visualizations and detailed security insights, CloudMapper is a key tool for improving cloud security hygiene.
