AWS Service: AWS Lambda
Question: What are the security features and best practices for AWS Lambda, and how do they protect against security threats?
Answer:
AWS Lambda provides a number of security features and best practices to help protect against security threats, including:
Identity and Access Management (IAM): AWS Lambda integrates with IAM to enable granular access control and management of permissions for individual users and groups.
Resource-based policies: AWS Lambda allows you to create resource-based policies that provide fine-grained control over access to your Lambda functions, allowing you to specify which resources are allowed to invoke the function and which actions are allowed.
Encryption: AWS Lambda provides encryption for data at rest and in transit, including support for AWS Key Management Service (KMS) for encryption of function code and environment variables.
Network security: AWS Lambda provides a Virtual Private Cloud (VPC) that allows you to isolate your functions from the public internet and control inbound and outbound traffic.
Compliance: AWS Lambda is compliant with a number of security standards and regulations, including PCI DSS, HIPAA, and SOC.
In addition to these security features, AWS provides best practices for securing Lambda functions, such as:
Minimizing the attack surface: AWS Lambda functions should be designed to only expose the necessary functionality, and should be configured to accept only trusted input.
Securing the code: AWS Lambda functions should be scanned for vulnerabilities and tested before deployment, and function code should be encrypted to prevent unauthorized access.
Monitoring and logging: AWS Lambda provides monitoring and logging capabilities that can be used to identify and investigate security threats, such as unusual behavior or unauthorized access.
Regular updates and patches: AWS Lambda functions should be updated regularly with security patches and software updates to address any known vulnerabilities.
By following these security features and best practices, you can help ensure that your AWS Lambda functions are secure and protected against security threats.
