Maintain current contact details

AWS remediation

+### Console +1. Sign in as the account root user. +2. Open AWS Account settings. +3. Update primary contact details (name, email, phone, address). +4. Save and periodically re-validate details. + +### AWS CLI +~~~bash +aws account put-contact-information \

• --contact-information file://contact-information.json +~~~

+Example file: +~~~json +{

• "FullName": "Security Team",
• "AddressLine1": "Street 1",
• "City": "City",
• "StateOrRegion": "State",
• "DistrictOrCounty": "County",
• "PostalCode": "00000",

Multiple Remediation Paths

AWS

SERVICE-WIDE (RECOMMENDED when many resources are affected): Deploy centralized guardrails and remediation using AWS Config Conformance Packs and (if applicable) AWS Organizations SCPs.

aws configservice put-organization-conformance-pack --organization-conformance-pack-name <pack-name> --template-s3-uri s3://<bucket>/<template>.yaml

ASSET-LEVEL: Apply the resource-specific remediation steps above to only the affected assets.

PREVENTIVE: Add CI/CD policy checks (CloudFormation/Terraform validation) before deployment to prevent recurrence.

Operational Rollout Workflow

Use this sequence to reduce risk and avoid repeated drift.

1. Contain at Service-Wide Scope First (Recommended)

• AWS: deploy/adjust organization conformance packs and policy guardrails.

aws configservice put-organization-conformance-pack --organization-conformance-pack-name <pack-name> --template-s3-uri s3://<bucket>/<template>.yaml

2. Remediate Existing Affected Assets

• Execute the control-specific Console/CLI steps documented above for each flagged resource.
• Prioritize internet-exposed and production assets first.

3. Validate and Prevent Recurrence

• Re-scan after each remediation batch.
• Track exceptions with owner and expiry date.
• Add preventive checks in IaC/CI pipelines.
