Zero trust for business applications

A practical explanation of identity, access, device, network and audit controls for custom business software.

Zero trust means the application does not assume that a user, device or network location is automatically safe. Every sensitive action is checked against identity, role, context and policy.

ControlPurposeExample
MFAReduce account takeover riskRequire verification for admin access
RBACLimit what roles can doFinance can approve invoices, not edit code
Audit logsTrack sensitive actionsRecord exports, approvals and permission changes

  • Log sensitive exports, permission changes and client-facing communication.
  • Review dormant accounts and unused roles on a fixed schedule.
