Business Continuity & Disaster Recovery Policy

Document owner: [Owner/Role]
Approved by: [Steering Committee / CISO]
Effective date: [YYYY-MM-DD]
Review cadence: [Annually]


1. Purpose & Scope

This policy establishes mandatory requirements for [Organization]'s ability to recover from disruption — outages, ransomware, natural disaster, or vendor failure. It applies to all systems, with the tightest requirements applied to kill-chain systems defined in Authentication Policy §2.1.


2. Policy Statements

2.1 Business Impact Analysis (BIA)

  • A BIA must be conducted at least annually, identifying critical processes, dependencies, and acceptable downtime.

2.2 Recovery Objectives by Tier

Tier RTO (Recovery Time) RPO (Recovery Point / max data loss)
Kill-chain (IdP, PKI, backup infra, break-glass vault) ≤ 4 hours ≤ 15 minutes
Critical business systems ≤ 24 hours ≤ 4 hours
Standard systems ≤ 72 hours ≤ 24 hours
Low-priority systems Best effort Best effort

2.3 Backup Requirements

  • Backups must be encrypted (per Secrets & Key Management Policy §2.3) and include at least one copy that is offline or immutable (air-gapped or WORM), unreachable by a compromised production credential.
  • Backup restoration must be tested at least quarterly for kill-chain systems, annually for others.

2.4 DR Testing

  • A full failover test must be conducted at least annually for kill-chain and critical systems.
  • Tests must follow the calibrated-dose principle: bounded blast radius, non-production first where feasible, pre-agreed abort condition — consistent with Authentication Policy §2.13 and Incident Response Policy §3.6.

2.5 Break-Glass & Emergency Access During DR

  • DR procedures must account for break-glass account availability when the primary IdP is part of the outage — see Authentication Policy §3 and §2.6 (graceful degradation).

2.6 Greenfield Rebuild Capability

  • [Organization] must maintain the documented, version-controlled capability to rebuild its environment from scratch — not merely restore from backup — at least once every five years, or on demand after a compromise where restoring from backup risks reintroducing the compromised state.
  • This capability must be exercised, not just claimed on paper; an untested greenfield rebuild plan is treated the same as untested break-glass access.

2.7 Enforcement

  • Systems without a current BIA, tested backup, or documented RTO/RPO must be remediated or formally excepted with CISO approval.

3. Antifragility Alignment

This policy is built to the five pillars of the organization's internal Antifragile Enterprise Manifest.

Pillar Applied In How
1. Structural Decoupling §2.6 Greenfield rebuild capability is the ultimate expression of decoupling — the org can leave its own compromised/legacy state behind entirely
2. Optionality Preservation §2.3 Offline/immutable backup copy preserves the option to recover even if the primary environment (and its credentials) is fully compromised
3. Stress-to-Signal Conversion §2.4 DR tests are dosed exercises, not annual theater — findings feed structural fixes per Authentication Policy §2.12
4. Sovereign Intelligence §2.6 Rebuild capability requires documented, owned architecture knowledge — the antidote to "only Dave knows how this works"
5. Asymmetric Payoff Design (Barbell) §2.2 4-hour RTO concentrated on kill-chain systems; low-priority systems get best-effort — no moderate RTO spread evenly across everything
