In systems processing settlement between banking and blockchain rails, perimeter-based security is insufficient. When infrastructure connects banking networks, public blockchains, partner APIs, and client interfaces, there is no "inside" and "outside" — only a continuous attack surface.
Zero Trust Applied to Settlement
Zero Trust is not a product — it's an architectural principle. At Infracash, every component verifies every request. Authentication is mutual (mTLS), authorization is granular (RBAC + ABAC), and every access decision is logged and auditable.
Defense in Depth
Security operates in multiple layers: network, transport, application, data, and operational.
HSM and Key Management
Critical cryptographic operations are executed in FIPS 140-2 Level 3 certified HSMs. Keys never exist in cleartext outside the HSM.
