# Seed System Identities & Hardening

To prevent administrative deadlocks and protect critical account structures, **Asterisk 2** implements defensive software locks. These controls safeguard core identity records against unwanted lifecycle modifications.

## Administrative Account Protection Rules

The flowchart below maps out the validation rules protecting seed identity databases from accidental deletion:

    %% User Request
    subgraph AdminConsole["Authenticated Admin Portal"]
        ActionReq["Account Modification Action<br/>(POST /api/Admin/User/Delete)"]
    end

    %% Security Interception
    subgraph ControllerLogic["AdminController Security Pipeline"]
        TargetLookup["Load Target User Profile<br/>(Target.UserName)"]
        SelfCheck["Session Context Evaluation<br/>(Target.Id == ActiveUser.Id)"]
    end

    %% Defense Core
    subgraph DefenseEngine["Account Immutability Logic"]
        SeedCheck["Seed Account Match Engine<br/>(Target.UserName == 'admin')"]
        DbCommit["Execute Database Transaction"]
    end

    %% Rejections
    RejectSelf["Abort Action<br/>(Error: Self-Deletion Prevention)"]
    RejectSeed["Abort Action<br/>(Error: Immutability Violation)"]

## Operational Hardening Protocols

### 1. Seed Root Administrator Protection
During application setup, the persistence layer provisions a core administrative record (`admin`). To ensure platform recovery availability, database controller rules mark this user record as immutable. Deletion commands targeting the root username string are rejected to prevent platform lockouts.

### 2. Self-Deletion Prevention Rules
To prevent an active administrator session from deleting its own record during management operations, controllers validate target IDs against user authentication claims. If the target matches the active session, the delete action is dropped.

### 3. Automated Authentication Lockouts
To stop password brute-forcing, user identity engines track unsuccessful login loops. If a user record accumulates multiple failed validation attempts, the profile enters a temporary lockout timeout state, entirely rejecting subsequent login validations.
