Borealis is a remote management platform with a simple, visual automation layer, enabling you to leverage scripts, Ansible playbooks, and advanced nodegraph-based automation workflows. I originally created Borealis to work towards consolidating the core functionality of several standalone automation platforms in my homelab, such as TacticalRMM, Ansible AWX, SemaphoreUI, and a few others.

|
||||
⚠️**Security Note**: Server/Client/API authentication mechanisms are not yet enabled. For your own safety, use Borealis in controlled environments only.

## Security Breakdowns
|
||||
The process that agents go through when authenticating securely with a Borealis server can be a little complex, so I have included a sequence diagram below to go over the core systems so you can visually understand what is going on behind-the-scenes.
|

|
||||
### Agent/Server Enrollment
|

participant Operator
|

participant Server
|
||||
participant SYS as "SYSTEM Agent"
|
||||
participant CUR as "CURRENTUSER Agent"
|
||||
|
||||
Operator->>Server: Request installer code
|
||||
Server-->>Operator: Deliver hashed installer code
|
||||
Note over Operator,Server: Human-controlled code binds enrollment to known device
|
||||
|
||||
par TLS Handshake (SYSTEM)
|
||||
SYS->>Server: Initiate TLS session
|
||||
Server-->>SYS: Present TLS certificate
|
||||
and TLS Handshake (CURRENTUSER)
|
||||
CUR->>Server: Initiate TLS session
|
||||
Server-->>CUR: Present TLS certificate
|
||||
end
|
||||
Note over SYS,Server: Certificate pinning plus CA checks stop MITM
|
||||
Note over CUR,Server: Pinning also blocks spoofed control planes
|
||||
|
||||
SYS->>SYS: Generate Ed25519 identity key pair
|
||||
Note right of SYS: Private key stored under Certificates/... protected by DPAPI or chmod 600
|
||||
CUR->>CUR: Generate Ed25519 identity key pair
|
||||
Note right of CUR: Private key stored in user context and DPAPI-protected
|
||||
|
||||
SYS->>Server: Enrollment request (installer code, public key, fingerprint)
|
||||
CUR->>Server: Enrollment request (installer code, public key, fingerprint)
|
||||
|
||||
Server->>Operator: Prompt for enrollment approval
|
||||
Operator-->>Server: Approve device enrollment
|
||||
Note over Operator,Server: Manual approval blocks rogue agents
|
||||
|
||||
Server-->>SYS: Send enrollment nonce
|
||||
Server-->>CUR: Send enrollment nonce
|
||||
SYS->>Server: Return signed nonce to prove key possession
|
||||
CUR->>Server: Return signed nonce
|
||||
Note over Server,Operator: Server verifies signatures and records GUID plus key fingerprint
|
||||
|
||||
Server->>SYS: Issue GUID, short-lived token, refresh token, server cert, script-signing key
|
||||
Server->>CUR: Issue GUID, short-lived token, refresh token, server cert, script-signing key
|
||||
Note over SYS,Server: Agent pins cert, stores GUID, DPAPI-encrypts refresh token
|
||||
Note over CUR,Server: Agent stores GUID, pins cert, encrypts refresh token
|
||||
Note over Server,Operator: Database keeps refresh token hash, key fingerprint, audit trail
|
||||
|
||||
loop Secure Sessions
|
||||
SYS->>Server: REST heartbeat and job polling with Bearer token
|
||||
CUR->>Server: REST heartbeat and WebSocket connect with Bearer token
|
||||
Server-->>SYS: Provide new access token before expiry
|
||||
Server-->>CUR: Provide new access token before expiry
|
||||
SYS->>Server: Refresh request over pinned TLS
|
||||
CUR->>Server: Refresh request over pinned TLS
|
||||
end
|
||||
|
||||
Server-->>SYS: Deliver script payload plus Ed25519 signature
|
||||
SYS->>SYS: Verify signature before execution
|
||||
Server-->>CUR: Deliver script payload plus Ed25519 signature
|
||||
CUR->>CUR: Verify signature and reject tampered content
|
||||
Note over SYS,CUR: Signature failure triggers re-enrollment and detailed logging
|
||||
Note over Server,Operator: Persistent records and approvals sustain long term trust
