Serverless Security
The practice of securing serverless applications and functions to mitigate risks and vulnerabilities inherent in serverless architectures.
Description
Serverless security refers to the measures and practices implemented to protect serverless applications, which run on cloud infrastructure without the need for traditional server management. In the AWS ecosystem, serverless computing is primarily facilitated by services such as AWS Lambda, API Gateway, and DynamoDB. While serverless architectures reduce operational overhead, they introduce unique security challenges. For instance, the ephemeral nature of serverless functions means that traditional security measures, like firewalls and intrusion detection systems, may not be as effective. Security in this context involves ensuring proper access controls, managing API security, and safeguarding data in transit and at rest. Additionally, monitoring and logging are critical for detecting anomalies and responding to potential threats. By leveraging AWS services such as AWS IAM for permissions, AWS WAF for web application protection, and AWS CloudTrail for logging, organizations can enhance their serverless security posture and ensure compliance with industry regulations.
Examples
- Using AWS IAM roles to enforce least privilege access for Lambda functions.
- Implementing AWS WAF to protect APIs from common web exploits.
Additional Information
- Regularly auditing serverless functions for security vulnerabilities using AWS Inspector.
- Employing encryption for sensitive data stored in DynamoDB to enhance data security.
