IAM Privilege Escalation in Cloud

Summary

IAM Privilege Escalation in Cloud is a type of attack where adversaries exploit misconfigurations or vulnerabilities in Identity and Access Management (IAM) policies to gain unauthorized elevated permissions within cloud environments, enabling them to perform actions beyond their original access rights.

Key Characteristics

• Exploitation of overly permissive or misconfigured IAM roles, policies, or permissions.
• Use of chained permissions or role assumptions to escalate privileges incrementally.
• Targeting cloud platforms such as AWS, Azure, or Google Cloud where IAM governs access control.
• Often involves leveraging automation or scripting to identify and exploit privilege gaps.
• May lead to unauthorized access to sensitive data, resource control, or lateral movement within the cloud environment.

Defensive Controls

• Implement the principle of least privilege by assigning minimal necessary permissions.
• Regularly audit and review IAM policies and role assignments for excessive permissions.
• Enable multi-factor authentication (MFA) for sensitive roles and accounts.
• Use IAM policy simulation and access analyzer tools to detect potential privilege escalation paths.
• Monitor and log IAM activities to detect anomalous behavior or unauthorized privilege changes.
• Apply role separation and enforce strict trust boundaries between services and users.

Related Security Solutions

Cloud security posture management (CSPM) tools, identity governance and administration (IGA) solutions, privileged access management (PAM) platforms, cloud-native IAM monitoring services, and security information and event management (SIEM) systems are commonly used to detect, prevent, and respond to IAM privilege escalation attacks in cloud environments.
