Security ​

Purpose ​

Define the baseline security expectations for Posh Nosh V2 before detailed business modules are implemented.

Scope ​

Authentication, session handling, authorisation, secure defaults, and protection of operational and financial information.

Actors ​

  • System users
  • Authorised administrators
  • SF Media support staff
  • External integration services

Users, roles, permissions, sessions, audit events, API credentials, and integration accounts.

Business Rules ​

  • SEC-001 — Every non-public system function must require an authenticated user or explicitly authorised service account.
  • SEC-002 — Access must be denied by default when no applicable permission is granted.
  • SEC-003 — Financial information must only be available to explicitly authorised roles.

Workflow ​

  1. A user authenticates.
  2. The system establishes a secure session.
  3. Each requested action is checked against current permissions.
  4. Security-relevant events are audited.

Validation ​

Authentication inputs, session state, permissions, and integration credentials must be validated server-side.

Permissions ​

Only authorised administrators may manage users, roles, and permission assignments.

Audit & History ​

Successful and failed authentication events, permission changes, and sensitive administrative actions must be recorded appropriately.

Exceptions & Edge Cases ​

  • A user's permissions change during an active session.
  • An account is disabled while the user is signed in.
  • Repeated authentication attempts indicate possible abuse.
  • An integration credential expires or is revoked.
  • Users, roles, and permissions

Open Decisions ​
