CyberSecurity

01- Definition:

A documented strategy & set of procedures to ensure that critical business operations can continue — or recover quickly — during and after a disruption.

02- Purpose:

• Minimize downtime & financial loss.

• Protect employees, customers & reputation.

• Comply with standards (e.g., ISO 22301 & NIST SP 800-34). 

03- Practices: 

Here are the 10 key steps for a Business Continuity Plan (BCP) — aligned with ISO 22301 & NIST SP 800-34:

1. Obtain Management Commitment
   — Secure top management support, resources, and sponsorship.

2️. Conduct Business Impact Analysis (BIA)
— Identify critical business functions, dependencies, and recovery priorities.

3️. Perform Risk Assessment
— Assess threats, vulnerabilities, and likelihood of disruptions.

4️. Define Recovery Strategies
— Develop alternatives and solutions to continue operations during and after disruptions.

5️. Develop the Business Continuity Plan
— Document procedures, teams, contact lists, and action steps.

6️. Establish Incident Response & Communication Plan
— Define how to respond to incidents and communicate with internal & external stakeholders.

7️. Allocate Roles & Responsibilities
— Form dedicated teams with clear roles and escalation paths.

8️. Train & Educate Employees
— Conduct awareness sessions and role-specific training.

9️. Test, Exercise & Evaluate the Plan
— Regularly simulate scenarios to validate and improve the plan.

10. Maintain & Update the Plan
— Periodically review and update to reflect business and risk changes.

04- Practical guide for BCP

• Disaster Recovery (DR)

  • • IT systems & data recovery

    • Restore servers & apps after a datacenter fire.

• Emergency Response Plan (ERP)

  • • Immediate safety & evacuation

    • Fire drills, active shooter, chemical spill response.

• Crisis Management Plan (CMP)

  • • Leadership decisions & PR

    • CEO & team manage a reputational crisis after a breach.

• Incident Response (IRP)

  • • Cybersecurity incidents

    • Detect, contain, and eradicate ransomware.

• IT Service Continuity (ITSC)

  • • Keeping IT services online

    • Switching to cloud failover during an outage.

• Pandemic/Health Response Plan

  • • Continuity during epidemics

    • Shifting to remote work during COVID-19.

• Work Area Recovery (WAR)

  • • Alternative workplaces

    • Renting temporary offices for staff after HQ floods.

• Data Backup & Restoration Plan

  • • Data integrity & availability

    • Daily backups to offsite/cloud & restore when needed.

• Supply Chain Continuity Plan

  • • Vendor/supplier resilience

    • Switching to backup suppliers when primary fails.

• Communication/Notification Plan

  • • Internal & external messaging

    • Notifying employees & regulators of an outage.

05- Business Continuity (Disaster Recovery)

1. Preparation

2. Detection

3. Action

4. KPIs

• RTO

• RPO

• Automation%

• No of errors during the Switch-over

• No of errors during switch-back

Phase 3: Execute & Operate

• 3. Planned Maintenance Windows: Execute maintenance during approved low-impact periods with defined business and technical approvals (ISO/IEC 20000-1).

• 11. Certificate & Key Management: Monitor TLS certificates, encryption keys, tokens, and credentials to prevent expiration-related outages (ISO/IEC 27001).

• 12. Configuration Baseline Management: Maintain approved configuration baselines and detect unauthorized changes (ISO/IEC 20000-1 / ISO/IEC 27001).

• 16. Change Management: Associate maintenance with an approved change, risk assessment, implementation plan, and rollback plan (ISO/IEC 20000-1).

• 17. Pre-Maintenance Readiness Check: Verify backup, capacity, dependencies, monitoring, access, prerequisites, and rollback readiness (NIST / ITSM Best Practice).

Phase 4: Validate & Improve

• 13. Health & Performance Monitoring: Continuously monitor infrastructure, applications, APIs, databases, and business transactions (ISO/IEC 20000-1).

• 15. Performance Baseline: Establish baseline KPIs and compare performance before and after maintenance (ITSM Best Practice).

• 18. Post-Maintenance Validation: Execute health checks, smoke tests, business transactions, and monitoring validation after maintenance (ISO/IEC 20000-1).

• 19. Maintenance Automation: Automate patching, health checks, certificate monitoring, configuration validation, and reporting where feasible (NIST SP 800-40 Rev. 4).

• 20. Continuous Improvement: Analyze incidents, recurring failures, maintenance results, and trends to continuously improve maintenance (ISO 55001 / ISO/IEC 20000-1).
