🔐 HSM

Hardware Security Modules for Non-Exportable Keys & Audit-Grade Crypto

Hardware Security Modules (HSMs) are tamper-resistant appliances that generate, store, and use cryptographic keys without ever exposing private material in software. SolveForce designs HSM programs (on-prem, colo, and cloud-adjacent) with dual-control/quorum, envelope encryption, code & TLS signing, and audit-grade evidence—so encryption, identity, and signing remain provable and safe.

Where HSM fits in the SolveForce model:
🔒 Security (Semantics) → Cybersecurity • 🔑 Key Fabric → Key Management / HSM • 🪪 Certificates/Trust → PKI
🧾 Identity → IAM / SSO / MFA • 🔐 Encryption → Encryption • 📊 Evidence/Automation → SIEM / SOAR
☁️ Cloud & Interconnect → Cloud • Direct Connect • 🏢 Facilities → Colocation

🎯 Outcomes (Why HSM)

  • Non-exportable keysfor root CA, KEKs, code/TLS signing—never leaves hardware.
  • Quorum & dual-control(M-of-N) for destructive actions (unwrap/destroy/zeroize).
  • Envelope encryption at scale(root → KEK → DEK) with fast rotation and no data loss.
  • Proven trust— FIPS-validated hardware, tamper evidence, immutable audit logs.
  • Low latency cryptography— HA clusters sized for JWT/TLS/signing throughput.

🧱 HSM Building Blocks (Spelled Out)

  • FIPS 140-2/140-3 validated hardware— secure boundary, tamper-responding, secure RNG.
  • Administrative personas— Security Officer, Crypto Officer, Auditor; separation of duties by policy.
  • Quorum (M-of-N) & Dual-Control— multiple humans + roles for key unwrap/destroy and policy changes.
  • Key hierarchy— Root in HSM → Key-Encryption Keys (KEKs) per service/tenant/env → Data-Encryption Keys (DEKs) per dataset/object.
  • Backup/Escrow— HSM-wrapped key backups (or Shamir shares) stored off-site; recovery tested quarterly.

🔐 HSM Use Cases (Concrete & Common)

  • Certificate Authorities (PKI)— root/intermediate CA keys; CRL/OCSP signing; ACME EAB support. → PKI
  • TLS private keys— terminate TLS with non-exportable keys; support for ACME automation. → Encryption
  • JWT / OAuth2 / OIDC— sign ID/Access tokens; JWKS rotation, kid headers, staged key rollover. → IAM / SSO / MFA
  • Code & Container Signing— CI/CD artifact signing (Cosign/Sigstore), firmware, drivers; attestations attached to builds.
  • Database/Storage Encryption— TDE/master keys; KEK/DEK re-wrap model for fast rotation.
  • Payments & Tokenization— PAN encryption, HSM-resident keys for token vaults; PCI DSS alignment. → DLP

🧭 Deployment Patterns (Where to Put the HSM)

  • On-Prem / Campus— low-latency crypto near apps; full physical control.
  • Colocation (carrier-dense)— proximity to Direct Connect/ExpressRoute/Interconnect; diverse carriers; cross-connects. → Colocation • Direct Connect
  • Cloud-Adjacent— connect physical HSMs to cloud workloads over private on-ramps; or pair with cloud HSM/KMS for hybrid models. → Cloud
  • Cluster & HA— active/active or active/standby with HSM-to-HSM sync, regional redundancy, and tamper alarms to SIEM.

🔄 Envelope Encryption (No-Drama Rotation)

1) Generate DEK to encrypt data.
2) Wrap DEK with a KEK (inside HSM/KMS); store wrapped DEK with ciphertext.
3) Rotate KEK → re-wrap DEKs (no data re-encrypt).
4) Rotate DEKs → use new DEKs for new data; bulk re-encrypt as policy allows.
5) Revoke/Disable → flip state, retain evidence; plan back-out.

Result: fast rotations, no plaintext key exposure, and clean audit trail.

🧰 Integration Patterns (Apps & Infrastructure)

  • JWT/JWS/JWE— HSM-backed signing keys; JWKS endpoint rotation; dual-publishing for graceful key cutovers.
  • KMS + HSM Hybrid— use cloud KMS for API-scale access to wrapped data keys, with on-prem HSM holding the KEK/root keys (HYOK/CMK patterns).
  • DB TDE— master in HSM, tablespace keys as DEKs; re-wrap on KEK rotate.
  • Object Storage— SSE-KMS, per-bucket/object DEKs; enforce CMK residency by region.
  • CI/CD— signer service that abstracts HSM calls; approvals for production sign; attach attestations to artifacts.
  • TLS Offload— HSM-resident private keys; ACME automation for renewals, mTLS for service-service.

🛡️ Access Controls (No Single Person Can Burn the House Down)

  • RBAC/ABAC— separate Security Officer, Crypto Officer, and Auditor.
  • M-of-N Quorum— export/destroy/zeroize needs multiple key cards + PINs from different people.
  • Dual-Control— two distinct approvers for key rotation & policy edits.
  • JIT & PAM— short-lived elevation with session recording. → PAM
  • Policy Conditions— source IP/ASN, time windows, device posture; break-glass token path with strict logging.

📜 Compliance Mapping (Examples)

  • PCI DSS 3.5/3.6— key protection, dual-control, split knowledge, lifecycle docs.
  • ISO/IEC 27001/27002— cryptographic controls & key management policy.
  • HIPAA— ePHI encryption integrity; custody evidence for keys.
  • NIST SP 800-57 / 800-53 (SC-12/SC-13)— key lifecycles & crypto services.
  • FedRAMP— HSM residency, audit logging, retention.

📊 Observability & Evidence

  • Audit Streams— create/unwrap/destroy, policy/role changes, backup/restore, tamper events.
  • Usage Analytics— op counts by key, latency heatmaps, throttles, unusual spikes.
  • Chain-of-Custody— hash/ID every action; export to SIEM; cases linked to changes. → SIEM / SOAR

🧪 Safety Nets & Drills

  • Game Days— KEK rotation, HSM failover, regional outage; validate end-to-end.
  • Backup/Restore Tests— M-of-N media, off-site storage, cold-start runbooks.
  • Kill-Switch— disable a key quickly (deny decrypt/sign) with documented business impact path.
  • Backout— re-enable prior KEK alias; publish new JWKS; retest clients.

🛠️ Implementation Blueprint (No-Surprise Rollout)

  1. Inventory & classification — which keys exist today; where; for what (encrypt/sign/wrap).
  2. Choose platform — network HSM cluster + (optional) cloud HSM/KMS; HA/DR regions.
  3. Design hierarchy — Root in HSM; KEKs per service/tenant/env; DEKs per dataset/object.
  4. Access policy — RBAC/ABAC, M-of-N quorum, dual-control, break-glass, ITSM approvals.
  5. Integrate apps — SDK/PKCS#11/JCE; CI/CD signing; DB TDE; TLS/mTLS; JWKS rotation.
  6. Observability — send audit to SIEM; SLO dashboards; SOAR playbooks for revoke/disable/rotate.
  7. Compliance packs — policy docs, lifecycle SOPs, rotation calendar, evidence exports.
  8. Drills — rotation, restore, disable; publish RCAs and improvements.

The systems and policies that determine who a user is, what resources they may access, and how that access is authenticated and reviewed.

Multi-Factor Authentication (MFA)

A login control requiring more than one form of verification, such as a password plus an authenticator app, security key, or biometric factor.

Colocation

Placing customer-owned servers and network equipment in a professionally operated data center that provides power, cooling, physical security, and connectivity.

API

An application programming interface is a defined way for software systems to exchange data or request functions from one another.

Artificial Intelligence (AI)

Software designed to perform tasks involving prediction, classification, generation, reasoning, or decision support. Business use still requires clear data, governance, security, and human accountability.
