Frequently asked questions

What is centralized logging (ELK, Splunk)?

Centralized logging solutions like ELK and Splunk are used for collecting and analyzing logs from various sources in a serverless environment.

How should I manage IAM roles to minimize permissions?

Implement the principle of least privilege by granting IAM roles only the necessary permissions required for each service or function, reducing potential security risks.

Should I store secrets directly in my code?

Never store sensitive information like API keys or passwords directly within your codebase; instead, utilize dedicated secret management services.

What services should I use for managing secrets?

Consider using services like AWS Secrets Manager or Parameter Store to securely store and manage configuration data and sensitive information.
