Business Continuity & Information Security Policy

1. Purpose

The purpose of this policy is to establish the organization’s approach to maintaining the confidentiality, integrity, and availability of information and critical business services during disruptions.

The organization recognizes that business continuity and information security are closely connected. A cybersecurity incident, cloud outage, supplier failure, ransomware attack, data loss, system failure, or other disruption may affect the organization’s ability to deliver services.

This policy establishes the principles for:

  • Protecting critical information and systems.
  • Maintaining availability of critical business services.
  • Preparing for disruptive events.
  • Responding to information-security-related disruptions.
  • Recovering systems and business operations.
  • Protecting backups and recovery resources.
  • Maintaining appropriate communication.
  • Testing business continuity and recovery arrangements.
  • Learning from disruptions and improving resilience.

2. Scope

This policy applies to:

  • Employees
  • Contractors
  • Temporary personnel
  • Management
  • IT and security teams
  • Cloud and infrastructure teams
  • Development and DevOps teams
  • Business process owners
  • Suppliers and service providers where applicable
  • Information assets
  • Business applications
  • Cloud environments
  • Production systems
  • Corporate systems
  • Networks
  • Databases
  • SaaS platforms
  • Source code and CI/CD systems
  • Backup and recovery systems
  • Critical third-party services
  • Physical locations supporting critical operations

The policy applies to both cybersecurity incidents and non-cybersecurity disruptions that could materially affect information security or critical business services.


3. Policy Statement

The organization shall maintain appropriate business continuity and information security arrangements based on business requirements and risk.

The organization shall:

  1. Identify critical business services and supporting information assets.
  2. Assess risks that could disrupt those services.
  3. Establish appropriate continuity and recovery requirements.
  4. Protect critical information and technology resources.
  5. Maintain appropriate backups and recovery capabilities.
  6. Establish incident response and escalation processes.
  7. Define recovery responsibilities.
  8. Test continuity and recovery arrangements periodically.
  9. Protect information during disruption and recovery.
  10. Review lessons learned after significant disruptions.
  11. Continually improve resilience based on changes in business, technology, threats, and risks.

4. Business Continuity Principles

The organization shall apply the following principles:

4.1 Business-Critical Services First

Continuity planning should focus first on services whose disruption could materially affect customers, revenue, regulatory obligations, security, or critical operations.

4.2 Risk-Based Planning

Continuity measures should be proportionate to the risk and business impact.

4.3 Security Must Continue During Disruption

Emergency recovery must not unnecessarily bypass security controls.

4.4 Recovery From a Trusted State

Systems should be recovered from known-good and appropriately protected sources.

4.5 Protect Information During Recovery

Confidential, personal, customer, financial, and other sensitive information must remain protected during emergency operations.

4.6 Defined Decision Authority

The organization should know who can declare a major disruption, activate recovery procedures, approve emergency actions, and authorize return to normal operations.

4.7 Test Before an Actual Crisis

Continuity and recovery arrangements should be tested periodically to identify weaknesses before a real disruption occurs.


5. Business Continuity Risk

The organization should consider disruptions such as:

  • Cyberattack
  • Ransomware
  • Cloud service outage
  • Cloud account compromise
  • Data breach
  • Database failure
  • Application failure
  • Infrastructure failure
  • Network outage
  • Power failure
  • Internet outage
  • Supplier failure
  • SaaS provider outage
  • Key-person unavailability
  • Loss of office or physical facility
  • Natural disaster
  • Fire
  • Flood
  • Pandemic or widespread workforce disruption
  • Major software failure
  • Backup failure
  • Data corruption
  • Accidental deletion
  • Critical vulnerability exploitation
  • Supply-chain compromise

The organization should periodically reassess these risks as the business and threat environment changes.


6. Business Impact Assessment

Business owners should identify the impact of disruption to critical services.

Assessment may consider:

Impact AreaExample
CustomerCustomers cannot access SaaS platform
RevenueTransaction processing unavailable
SecuritySecurity monitoring unavailable
RegulatoryRequired service or reporting unavailable
ContractualSLA or customer commitment affected
OperationalEmployees cannot perform critical processes
FinancialDirect or indirect financial loss
ReputationLoss of customer confidence
DataLoss, corruption, or unauthorized disclosure
SafetyPhysical or personnel safety impact

The organization should identify the maximum acceptable level of disruption for important services.


7. Recovery Objectives

Business continuity and recovery requirements should define appropriate objectives such as:

Recovery Time Objective (RTO)

The target period within which a service or system should be restored following disruption.

Recovery Point Objective (RPO)

The maximum acceptable amount of data loss measured in time.

For example:

ServiceRTORPO
Production SaaS Application4 hours1 hour
Customer Database4 hours1 hour
Identity/SSO4 hours4 hours
Internal Collaboration8 hours24 hours
Development Environment24 hours24 hours

These values are examples only and should be determined through business impact and risk assessment.


8. Critical Information and Assets

The organization shall identify information and technology resources required to maintain critical services.

Examples include:

  • Customer information
  • Production databases
  • Application source code
  • Cloud infrastructure
  • IAM/SSO
  • Encryption keys
  • Secrets
  • Configuration
  • Infrastructure-as-Code
  • CI/CD pipelines
  • DNS
  • Domain management
  • Backup systems
  • Monitoring
  • Security tooling
  • Customer support systems
  • Financial systems
  • Critical supplier services

Critical dependencies should be documented.


9. Information Security During Business Disruption

Security requirements shall continue to apply during business continuity and recovery activities.

Emergency actions should not unnecessarily result in:

  • Shared credentials
  • Disabled MFA
  • Uncontrolled administrative access
  • Unencrypted data transfer
  • Unapproved software
  • Uncontrolled remote access
  • Unprotected backups
  • Unlogged emergency changes
  • Uncontrolled temporary accounts
  • Unauthorized access to customer information

Where emergency exceptions are unavoidable, they should be:

  • Authorized.
  • Time-bound.
  • Documented.
  • Monitored.
  • Reviewed after the emergency.
  • Removed when no longer required.

10. Backup and Recovery

Critical information and systems should have appropriate backup and recovery arrangements.

Backup requirements should consider:

  • Criticality
  • RPO
  • Data sensitivity
  • Recovery requirements
  • Retention
  • Encryption
  • Access control
  • Geographic resilience where required
  • Backup integrity
  • Recovery testing

Backups should be protected against unauthorized modification and deletion.

For high-risk environments, the organization should consider controls such as:

  • Immutable backups
  • Separate backup accounts
  • Restricted administrative access
  • Separate credentials
  • Backup monitoring
  • Offline or logically isolated recovery copies where justified

11. AWS SaaS Example

For an AWS-based SaaS application, continuity may depend on:

Users → DNS → Load Balancer → Application → Database → Storage → Secrets → IAM → Monitoring

The organization should understand how failure of each dependency could affect the service.

For example, if a production database becomes unavailable:

  1. Incident is detected.
  2. Incident severity is assessed.
  3. Incident Response Team is activated if appropriate.
  4. Database availability is investigated.
  5. Backup/recovery options are assessed.
  6. Recovery decision is made.
  7. Database is restored or service is failed over according to the recovery procedure.
  8. Application connectivity is verified.
  9. Data integrity is validated.
  10. Security controls are verified.
  11. Customer service is restored.
  12. Incident and recovery actions are documented.
  13. Root cause and corrective actions are reviewed.

Recovery is not considered complete simply because the system is online.


12. Disaster Recovery

The organization should maintain appropriate disaster-recovery arrangements for critical technology services.

Disaster recovery may address:

  • Cloud infrastructure
  • Databases
  • Applications
  • Network services
  • Identity services
  • Storage
  • Backups
  • DNS
  • CI/CD
  • Monitoring
  • Security tooling
  • Critical SaaS dependencies

Recovery procedures should define:

  • Trigger
  • Decision authority
  • Recovery sequence
  • Responsible roles
  • Required resources
  • Dependencies
  • Security controls
  • Validation steps
  • Communication
  • Return-to-normal process

13. Incident Response and Business Continuity

Information security incidents that significantly affect business operations should be managed using both incident-response and continuity processes.

For example:

Ransomware

Security Incident
→ Containment
→ Evidence Preservation
→ Impact Assessment
→ Business Continuity Activation
→ Recovery From Trusted Backup
→ Security Verification
→ Service Restoration
→ Customer/Regulatory Communication Assessment
→ Root Cause
→ Corrective Actions

Business continuity should not replace incident response.

Both processes should operate together.


14. Crisis Management

For significant disruptions, management may activate a crisis-management process.

Potential triggers include:

  • Major customer impact
  • Extended production outage
  • Major ransomware incident
  • Significant data breach
  • Critical cloud outage
  • Major supplier failure
  • Significant regulatory impact
  • Major financial or operational impact

The crisis-management process should establish:

  • Incident/crisis leader
  • Decision authority
  • Communication channel
  • Business priorities
  • Recovery priorities
  • Customer communication
  • Supplier coordination
  • Legal/privacy coordination
  • Management updates
  • Recovery approval

15. Communication During Disruption

Communication should be:

  • Timely
  • Accurate
  • Authorized
  • Fact-based
  • Appropriate for the audience
  • Consistent
  • Protected from unnecessary disclosure

Communication may involve:

  • Employees
  • Management
  • Customers
  • Suppliers
  • Cloud providers
  • Business partners
  • Legal/privacy advisers
  • Regulators
  • Insurance providers
  • Law enforcement where appropriate

Only authorized personnel should communicate externally about significant incidents or disruptions.


16. Emergency Communication

If normal corporate systems are unavailable or compromised, the organization should have alternative communication methods.

Examples may include:

  • Approved alternate messaging platform
  • Emergency phone contacts
  • Secondary email
  • Emergency contact list
  • Cloud-based communication channel
  • Incident-management platform

Alternative channels should themselves be appropriately protected.


17. Supplier and Cloud Dependency

Critical suppliers and cloud providers should be considered in continuity planning.

The organization should identify:

  • Critical supplier
  • Service provided
  • Business dependency
  • Information processed
  • Availability requirements
  • Supplier failure impact
  • Recovery options
  • Alternative supplier where justified
  • Contractual commitments
  • Supplier incident communication process
  • Exit or migration considerations

Cloud services should be assessed using the applicable shared-responsibility model.


18. People and Key-Person Dependency

Business continuity planning should consider the unavailability of critical personnel.

The organization should identify:

  • Critical roles
  • Backup personnel
  • Delegated authority
  • Required skills
  • Emergency contact information
  • Documentation required for recovery
  • Cross-training requirements

Critical recovery activities should not depend unnecessarily on one individual.


19. Remote Working and Alternate Operations

Where remote work is required during a disruption:

  • Approved devices should be used.
  • MFA should remain enabled.
  • Secure remote access should be used.
  • Sensitive information should remain protected.
  • Emergency access should be monitored.
  • Unauthorized personal storage should not be used for company information.
  • Security monitoring should continue where practical.

20. Emergency Change Management

Emergency changes may be necessary during a disruption.

Emergency changes should:

  1. Have a legitimate business or security reason.
  2. Be authorized by an appropriate person.
  3. Be documented.
  4. Be tested where practical.
  5. Be implemented with appropriate security controls.
  6. Be monitored.
  7. Be reviewed after implementation.
  8. Be reverted or formally incorporated into normal configuration where appropriate.

Emergency status must not become a permanent bypass of change management.


21. Recovery Verification

Before declaring recovery complete, the organization should verify:

  • Service availability
  • Data integrity
  • Authentication
  • Authorization
  • Security configuration
  • Network controls
  • Logging
  • Monitoring
  • Backup status
  • Vulnerability status
  • Secrets and credentials
  • Integration functionality
  • Customer functionality
  • Security alerts
  • Residual risk

The service owner and appropriate technical/security personnel should approve return to normal operations.


22. Return to Normal Operations

After recovery, the organization should:

  • Confirm the root cause is understood or appropriately managed.
  • Remove temporary emergency controls.
  • Remove temporary accounts.
  • Revoke emergency access.
  • Restore standard configurations.
  • Review security logs.
  • Verify monitoring.
  • Validate backups.
  • Review customer impact.
  • Complete required communications.
  • Record lessons learned.
  • Create corrective actions.
  • Reassess risk.
  • Update continuity and recovery documentation.

23. Testing and Exercises

Business continuity and recovery arrangements should be tested periodically.

Testing may include:

Tabletop Exercise

Discuss a disruption scenario and evaluate decision-making.

Technical Recovery Test

Restore systems or data in a controlled environment.

Backup Restore Test

Restore selected backups and validate data integrity.

Failover Test

Test switching to an alternate system or environment.

Communication Test

Test emergency communication channels.

Supplier Continuity Test

Validate critical supplier contacts and recovery arrangements.

Full or Partial Simulation

Simulate a realistic disruption where justified by risk.

Testing should produce documented results and corrective actions.


24. Lessons Learned

Following significant disruptions or exercises, the organization should review:

  • What happened?
  • What worked?
  • What failed?
  • Was the disruption detected quickly?
  • Were roles clear?
  • Was escalation timely?
  • Were backups available?
  • Was recovery successful?
  • Were security controls maintained?
  • Was customer communication effective?
  • Were suppliers responsive?
  • Were RTO/RPO objectives achieved?
  • What gaps were identified?
  • What improvements are required?

Lessons should be recorded and tracked to completion.


25. Business Continuity Documentation

The organization should maintain appropriate documentation such as:

  • Business Continuity Policy
  • Business Impact Assessment
  • Business Continuity Plans
  • Disaster Recovery Plan
  • Critical Service Register
  • Critical Dependency Register
  • Recovery Procedures
