Incident Response for Serverless on AWS

Introduction

Incident response in a serverless environment on AWS requires a tailored approach due to the unique characteristics of serverless architectures. This lesson covers the essentials of responding to incidents effectively in AWS Lambda and other serverless components.

Key Concepts

• Serverless Architecture: A model where the cloud provider dynamically manages the allocation of machine resources.
• Incident Response: A structured approach to handle and manage the aftermath of a security breach or cyberattack.
• Logging and Monitoring: Utilizing AWS services like CloudWatch and X-Ray for real-time insights into serverless applications.
• Security Best Practices: Implementing IAM roles, permissions, and least privilege access controls.

Incident Response Process

The incident response process consists of several key phases:

1. Preparation: Establish an incident response plan, team, and tools.
2. Identification: Use monitoring tools to detect anomalies or incidents.
3. Containment: Limit the damage by isolating affected components.
4. Eradication: Identify the root cause and eliminate the threat.
5. Recovery: Restore services and monitor for any signs of weaknesses.
6. Lessons Learned: Analyze the incident and update the response plan accordingly.

Best Practices

To enhance your incident response capabilities in AWS serverless environments, consider the following best practices:

• Implement logging through CloudTrail and CloudWatch.
• Regularly review IAM roles and permissions.
• Utilize AWS Config for compliance monitoring.
• Conduct regular security audits and vulnerability assessments.
• Automate incident response procedures where possible using AWS Lambda functions.
