Security Considerations in AWS Lambda

Security considerations for AWS Lambda

When developing an AWS Lambda function, it’s crucial to consider security from the outset to protect our application and data. Securing an AWS Lambda function is essential for several reasons.

• Data protection: Lambda functions often process and manipulate data. Securing them ensures the confidentiality, integrity, and availability of that data. Breaches can lead to data leaks, which can have serious legal and financial consequences.

• Access control: Lambda functions can interact with various AWS resources and services. Proper security ensures that only authorized entities can invoke or interact with the function, reducing the risk of unauthorized access.

• Abuse prevention: Attackers might discover and exploit our Lambda functions without proper security controls. For example, they could use our function to execute arbitrary code, launch denial-of-service (DoS) attacks, or incur unexpected charges. By following security best practices, we minimize the attack surface exposed by our Lambda functions, making it harder for attackers to find and exploit vulnerabilities. ...
