Lambda Function Associated with Privileged Policy

Lambda Function Associated with Privileged Policy

Overview

The Lambda Function Associated with Privileged Policy widget identifies Lambda functions linked to overly permissive IAM policies. This insight is crucial for IT Operations (IT Ops) and Security Operations (Sec Ops) engineers to ensure that serverless functions adhere to the principle of least privilege, reducing security risks and preventing unauthorized actions.

Why It Matters

For IT Engineers:

1. Policy Optimization:

   • Highlights Lambda functions with IAM policies granting excessive permissions, enabling IT Ops to refine these policies.

   • Ensures that functions operate with only the permissions required for their specific tasks.

2. Operational Efficiency:

   • Prevents resource misuse by restricting access to sensitive actions and data.

   • Supports cleaner and more manageable infrastructure by minimizing unnecessary policy complexity.

3. Compliance and Governance:

   • Aligns Lambda configurations with organizational policies and regulatory standards, ensuring proper governance.

For Security Engineers:

1. Risk Mitigation:

   • Identifies functions that could be exploited due to excessive permissions, such as accessing critical resources unnecessarily.

2. Threat Prevention:

   • Reduces the attack surface by ensuring functions cannot perform actions beyond their intended scope.

3. Policy Enforcement:

   • Enforces security best practices by adhering to the principle of least privilege for all serverless functions.

Practical Applications

• Policy Hardening: Review and modify IAM policies linked to Lambda functions to minimize privileges.

• Vulnerability Mitigation: Quickly identify and reconfigure overly permissive functions to prevent exploitation.

• Compliance Assurance: Ensure that Lambda functions meet regulatory requirements for secure and limited permissions.
