• Basic Scanning: To scan a single file or a directory, use the -f (file) or -d (directory) flags:
  checkov -f main.tf

  checkov -d /path/to/your/iac/code

• Output: Checkov provides a detailed output of passed and failed checks, including the check ID, description, the resource and file location, and a link to more information about the policy
• Specifying Frameworks: You can specify the IaC framework to scan using the --framework flag:

         checkov -d /path/to/kubernetes/manifests --framework kubernetes

         checkov -f eks-deploy-k8s.yaml

• Output Formats: Checkov supports various output formats using the --output flag, such as cli (default), json, junitxml, and sarif. For e.g, for JSON output format, use below command:
