Securing Lambda functions
Securing Lambda functions is a critical aspect of cloud-native applications running in serverless architectures. Lambda functions can be triggered by various services and external sources. This makes them a potential entry point for malicious activities. This section aims to provide a comprehensive guide to securing Lambda functions, focusing on best practices and AWS-specific features.
Code integrity
Code integrity is the foundation of any secure application. Ensuring that the code running in your Lambda functions is exactly what you expect it to be is crucial for preventing unauthorized modifications and injections. Here, we will delve into several methods to ensure the integrity of your Lambda function code.
Code signing
Code signing is a crucial method for verifying the integrity of your Lambda function code. By attaching a digital signature, Lambda ensures that only signed and authorized code packages are deployed. This process adds a robust...
