How do you allow or restrict access to AWS services?

To allow or restrict access to AWS services:

1. IAM (Identity and Access Management):

Manage access by defining policies for users, groups, or roles.

2. Resource Policies:

Control access at the resource level for services like S3 and SQS.

3. NACLs (Network Access Control Lists):

Act as subnets' firewalls, defining rules for inbound and outbound traffic.

4. Security Groups:

Virtual firewalls at the instance level, controlling inbound and outbound traffic.

5. SCPs (Service Control Policies):

Control access across multiple accounts in AWS Organizations.

6. VPC Endpoints:

Privately connect to AWS services within a VPC, avoiding public IPs.
