A Company Prefers to Limit Running Amazon EC2 Instances to Those

question 256

Multiple Choice

A company prefers to limit running Amazon EC2 instances to those that were launched from AMIs pre-approved by the Information Security department. The Development team has an agile continuous integration and deployment process that cannot be stalled by the solution. Which method enforces the required controls with the LEAST impact on the development process? (Choose two.)

• A) Use IAM policies to restrict the ability of users or other automated entities to launch EC2 instances based on a specific set of pre-approved AMIs, such as those tagged in a specific way by Information Security.
• B) Use regular scans within Amazon Inspector with a custom assessment template to determine if the EC2 instance that the Amazon Inspector Agent is running on is based upon a pre-approved AMI. If it is not, shut down the instance and inform information Security by email that this occurred.
• C) Only allow launching of EC2 instances using a centralized DevOps team, which is given work packages via notifications from an internal ticketing system. Users make requests for resources using this ticketing tool, which has manual information security approval steps to ensure that EC2 instances are only launched from approved AMIs.
• D) Use AWS Config rules to spot any launches of EC2 instances based on non-approved AMIs, trigger an AWS Lambda function to automatically terminate the instance, and publish a message to an Amazon SNS topic to inform Information Security that this occurred.
• E) Use a scheduled AWS Lambda function to scan through the list of running instances within the virtual private cloud (VPC) and determine if any of these are based on unapproved AMIs. Publish a message to an SNS topic to inform Information Security that this occurred and then shut down the instance.
