A company runs a workload in a single VPC on AWS. The company’s architecture contains several interface VPC endpoints for AWS services, including Amazon CloudWatch Logs and AWS Key Management Service (AWS KMS). The endpoints are configured to use a shared security group. The security group is not used for any other workloads or resources.
After a security review of the environment, the company determined that the shared security group is more permissive than necessary. The company wants to make the rules associated with the security group more restrictive. The changes to the security group rules must not prevent the resources in the VPC from using AWS services through interface VPC endpoints. The changes must prevent unnecessary access.
The security group currently uses the following rules:
• Inbound - Rule 1
Protocol: TCP
Port: 443
Source: 0.0.0.0/0
• Inbound - Rule 2
Protocol: TCP
Port: 443
Source: VPC CIDR
• Outbound - Rule 1
Protocol: All
Port: All
Destination: 0.0.0.0/0
Which rule or rules should the company remove to meet with these requirements?
An ecommerce company is hosting a web application on Amazon EC2 instances to handle continuously changing customer demand. The EC2 instances are part of an Auto Scaling group. The company wants to implement a solution to distribute traffic from customers to the EC2 instances. The company must encrypt all traffic at all stages between the customers and the application servers. No decryption at intermediate points is allowed.
Which solution will meet these requirements?
A company has multiple AWS accounts. Each account contains one or more VPCs. A new security guideline requires the inspection of all traffic between VPCs.
The company has deployed a transit gateway that provides connectivity between all VPCs. The company also has deployed a shared services VPC with Amazon EC2 instances that include IDS services for stateful inspection. The EC2 instances are deployed across three Availability Zones. The company has set up VPC associations and routing on the transit gateway. The company has migrated a few test VPCs to the new solution for traffic inspection.
Soon after the configuration of routing, the company receives reports of intermittent connections for traffic that crosses Availability Zones.
