How do I configure security groups for my Lambda function in a VPC?

To configure security groups for your Lambda function in a VPC, you need to specify the security group IDs when you create or update the function.

What rules should I include in the security group?

Include rules that allow inbound traffic from the necessary sources, such as your VPC or specific IP addresses, and outbound rules for any services your Lambda needs to access.

Can I use multiple security groups for a single Lambda function?

Yes, you can associate multiple security groups with a single Lambda function to control access more granularly.

What happens if I don't configure a security group?

If you don't configure a security group, your Lambda function will not have any network access, which may prevent it from connecting to other resources.
