A company needs to apply security rules to a subnet for Amazon EC2 instances.
Which AWS service or feature provides this functionality?
Network ACLs
Security groups
AWS Certificate Manager (ACM)
AWS Config
Explanations:
Network ACLs are used to control inbound and outbound traffic at the subnet level, applying security rules to the subnet.
Security groups control traffic at the instance level, not at the subnet level.
AWS Certificate Manager (ACM) manages SSL/TLS certificates but does not provide subnet security rules.
AWS Config is used to assess, audit, and evaluate the configuration of AWS resources, not for applying security rules to subnets.
As far as I’m aware, the answer is:
Network ACLs
