What should the SysOps Administrator do to alleviate this concern?
Patch the vulnerability with Amazon Inspector.
Provide an AWS Trusted Advisor report showing which Amazon EC2 instances have been patched.
Redeploy the Amazon EC2 instances using AWS CloudFormation.
Patch the Linux operating system using AWS Systems Manager.
Explanations:
Amazon Inspector is a tool for discovering vulnerabilities in applications, but it does not patch the operating system. It helps in vulnerability assessment, not remediation.
AWS Trusted Advisor provides insights into best practices but does not specifically address patching the Linux OS or mitigate security vulnerabilities.
Redeploying EC2 instances using AWS CloudFormation would not directly address the vulnerability unless the instances are explicitly patched during the redeployment process. It is not an efficient solution for patching an OS vulnerability.
AWS Systems Manager can automate the process of patching the operating system. It provides a patch management feature to ensure that security patches are applied to Linux instances, directly addressing the vulnerability.
As I understand it, the answer is:
Patch the Linux operating system using AWS Systems Manager.
