Q: Your enterprise is undergoing SOC2 Type II and ISO 27001 certification. External auditors discovered multiple compliance violations: developers can bypass branch protections using admin privileges, build logs stored in third-party CI systems are vulnerable to deletion after 90 days, and there is no cryptographically verifiable link between a deployed production binary and an approved Jira change ticket. You must design and implement an end-to-end continuous compliance architecture across your CI/CD pipelines.

Configure GitHub repository rulesets requiring GPG or SSH signature verification on all commits. Reject any unsigned commits or force-pushes across all branches.

# Enforce signing verification via GitHub CLI / API
gh api -X PUT /repos/enterprise-org/billing-service/branches/main/protection \
  -F required_signatures=true \
  -F enforce_admins=true

Stream all CI/CD build outputs, step execution parameters, and environment logs directly to AWS S3 buckets configured with Object Lock in Compliance Mode (Write Once, Read Many - WORM).

Integrate a CI gate that queries Jira / ServiceNow APIs to verify that the Git commit references an approved, peer-reviewed change request before triggering the production deployment step.

# CI Verification Gate Script
COMMIT_MSG=$(git log -1 --pretty=%B)
JIRA_KEY=$(echo "$COMMIT_MSG" | grep -oE '[A-Z]+-[0-9]+' | head -n1)

if [ -z "$JIRA_KEY" ]; then
  echo "ERROR: Commit must contain a valid Jira ticket reference!" && exit 1
fi

TICKET_STATUS=$(curl -s -u "$JIRA_USER:$JIRA_TOKEN" \
  "https://jira.company.com/rest/api/2/issue/$JIRA_KEY" | jq -r '.fields.status.name')

if [ "$TICKET_STATUS" != "Approved" ]; then
  echo "ERROR: Jira ticket $JIRA_KEY is in state '$TICKET_STATUS', must be 'Approved'!" && exit 1
fi

Implement an automated compliance exporter that gathers pull request approvals, CI build IDs, Cosign signatures, and deployment timestamps into a cryptographically sealed compliance ledger (JSON-LD format) for instant audit review.
