# Workflows: HashiCorp Boundary Zero Trust Implementation

## Workflow 1: Initial Boundary Deployment

```
Step 1: Infrastructure Preparation
  - Provision PostgreSQL database for Boundary backend
  - Generate TLS certificates for controller and workers
  - Configure KMS (Vault Transit or AEAD for dev)
  - Set up network connectivity between components

Step 2: Controller Deployment
  - Install Boundary binary on controller hosts
  - Configure controller with database, KMS, and listeners
  - Initialize database schema
  - Verify controller health and API accessibility

Step 3: Worker Deployment
  - Install Boundary on worker hosts in each network zone
  - Configure worker with controller address and KMS
  - Register workers with tags for routing decisions
  - Verify worker registration and health

Step 4: Identity Provider Integration
  - Configure OIDC auth method with organizational IdP
  - Map IdP groups to Boundary managed groups
  - Test authentication flow end-to-end
  - Configure token and session expiry policies
```

## Workflow 2: Target Onboarding

```
Step 1: Create Scope Hierarchy
  - Define organization scope for each business unit
  - Create project scopes for environment isolation
  - Assign admin roles to scope owners

Step 2: Configure Host Catalogs
  - Static catalogs for fixed infrastructure
  - Dynamic catalogs for cloud resources (AWS, Azure, GCP)
  - Plugin-based catalogs for auto-discovery

Step 3: Define Targets
  - Map each target to host sets
  - Configure default ports and session limits
  - Enable session recording for privileged targets
  - Link credential sources (Vault libraries)

Step 4: Create Access Policies
  - Define roles with minimum necessary grants
  - Assign roles to managed groups from IdP
  - Test access with each role
  - Document access patterns and justifications
```

## Workflow 3: Vault Credential Integration

```
Step 1: Configure Vault Secrets Engines
  - Enable database secrets engine for dynamic credentials
  - Configure SSH secrets engine for certificate signing
  - Set up PKI engine for TLS certificates
  - Define roles with appropriate TTL and permissions

Step 2: Create Boundary Credential Stores
  - Create Vault credential store in Boundary
  - Provide Vault token with appropriate policies
  - Configure namespace if using Vault Enterprise

Step 3: Create Credential Libraries
  - Map Vault paths to Boundary credential libraries
  - Configure credential type (username_password, ssh_certificate)
  - Link libraries to targets as brokered or injected sources

Step 4: Test and Validate
  - Connect to target with dynamic credentials
  - Verify credentials are revoked after session end
  - Confirm session recording captures access
  - Validate audit logs contain credential events
```

## Workflow 4: Access Review and Audit

```
Step 1: Regular Access Review
  - Export role assignments and grant strings
  - Review with resource owners quarterly
  - Remove stale or unnecessary access
  - Update managed group filters if IdP groups change

Step 2: Session Recording Review
  - Review session recordings for privileged targets
  - Investigate anomalous session patterns
  - Export recordings for compliance evidence
  - Archive recordings per retention policy

Step 3: Compliance Reporting
  - Generate access control matrix from Boundary
  - Map controls to compliance framework requirements
  - Document exceptions and compensating controls
  - Present findings to audit and compliance teams
```
