  • Consulted: DevOps Team (provides input on deployment impact)
  • Informed: Marketing Team (aware of downtime schedules)

Inputs and Handoffs

  1. Plugin and Theme Governance: Maintain an approved list of plugins and themes with version tracking.
  2. Patch Windows: Define a weekly patch window for updates, with exceptions for critical vulnerabilities.
  3. Backup Strategy: Ensure daily backups are stored offsite and tested monthly.

Quality Gates

  1. Acceptance Criteria: All plugins must pass a security scan before deployment.
  2. Exception Handling: Document and justify any deviations from the hardening plan.
  3. Audit Trail: Maintain logs of all changes and access requests.

Cadence and Escalation

  • Monthly Review: Conduct a security audit and update the hardening plan.
  • Incident Response: Escalate any detected breaches to the IT Security Lead immediately.

Verification Items

  • Verify that all plugins are from trusted sources.
  • Confirm that backups are encrypted and accessible.
  • Ensure that incident response drills are conducted quarterly.

Ownership and Operating Model

Roles (RACI):

  • Business Owner (Accountable): Approves security budget, sets risk tolerance, and signs off on major changes. Must review quarterly reports.
  • Editorial Owner (Responsible): Documents procedures, maintains the hardening checklist, and ensures compliance with internal policies. Handoff: Signed checklist PDF to Technical Owner.
  • Technical Owner (Responsible): Implements controls (e.g., WAF rules, patch schedules), validates backups, and tests incident response. Handoff: Change tickets with before/after screenshots.
  • Reviewer (Consulted): External pentester or internal audit team. Escalation condition: Critical vulnerabilities unresolved after 72h.

Quality Gates:

  1. Pre-Implementation: Checklist items must reference a CVE ID, plugin changelog, or SHMLANG internal security policy (verification item: link policy repository).
  2. Post-Implementation: Technical Owner provides log excerpts showing blocked attacks or successful patches via wp-cli version --extra.

Cadence:

  • Weekly: Editorial Owner verifies plugin updates against WordPress vulnerability DB (input: wpscan --update output).

Limited Rollout Design

Baseline Establishment

  1. Roles and RACI: Assign ownership for security tasks (e.g., patch management, logging, backups) to specific team members.
  2. Inputs and Handoffs: Define inputs (e.g., vulnerability reports) and handoffs (e.g., patch deployment) between teams.
  3. Quality Gate: Set criteria for patch acceptance (e.g., no critical vulnerabilities post-deployment).
  4. Cadence and Escalation: Schedule weekly patch reviews and escalate unresolved issues within 48 hours.
  5. Audit Trail: Maintain a record of all actions, including patch details and responsible parties.

Observation Record

  1. Fields: Include fields for patch ID, deployment date, vulnerability severity, and verification status.
  2. Decision Criteria: Use severity levels (e.g., critical, high) to prioritize patches.
  3. Exceptions: Note any patches that fail verification and require rework.
  4. Acceptance Methods: Conduct post-deployment scans to confirm vulnerability resolution.

Explicit Decisions

  1. Continue: If patches meet acceptance criteria, proceed with the next rollout phase.
  2. Rework: If patches fail verification, address issues and retest.
  3. Stop: If critical vulnerabilities persist, halt rollout and reassess the plan.
