go-api

Sirius Go API SDK

A shared Go library for the Sirius vulnerability scanning platform, providing core data models, database operations, and service integrations.

Overview

The Sirius Go API SDK provides a unified interface for:

• Core Data Models: Host, Port, Vulnerability, Service structures
• Database Operations: PostgreSQL via GORM ORM
• Message Queue: RabbitMQ pub/sub integration
• Key-Value Store: ValKey/Redis operations
• NVD Integration: CVE data enrichment from National Vulnerability Database
• Source Attribution: Track which tool found each piece of data

Boundary With Procyon

go-api remains the shared Sirius SDK for domain models and additive helpers. It is the right place for Sirius-facing DTOs, persistence helpers, and neutral contracts that are reused across multiple Sirius repos.

The Procyon host/plugin runtime contract is intentionally not part of go-api. That contract is owned by the Procyon repository and is exposed there from github.com/SiriusScan/procyon/pkg/runtimeplugin.

Add new packages to go-api only when:

• More than one repo needs the same neutral Sirius contract or helper.
• The contract is not owned by a single runtime or control-plane component.
• The change can be released additively without breaking existing consumers.

Installation

go get github.com/SiriusScan/go-api@latest

Quick Start

package main

import (
    "github.com/SiriusScan/go-api/sirius"
    "github.com/SiriusScan/go-api/sirius/host"
    "github.com/SiriusScan/go-api/sirius/postgres"
)

func main() {
    // Initialize database connection
    if err := postgres.InitDB(); err != nil {
        panic(err)
    }

    // Create host data
    hostData := sirius.Host{
        IP:       "192.168.1.100",
        Hostname: "server.local",
        Ports: []sirius.Port{
            {Number: 22, Protocol: "tcp", State: "open"},
            {Number: 80, Protocol: "tcp", State: "open"},
        },
    }

    // Add host to database
    if err := host.AddHost(hostData); err != nil {
        panic(err)
    }

    // Retrieve host
    retrieved, err := host.GetHost("192.168.1.100")
    if err != nil {
        panic(err)
    }

    println("Found host:", retrieved.IP)
}

Features

Core Data Models

type Host struct {
    HID             string
    OS              string
    OSVersion       string
    IP              string
    Hostname        string
    Ports           []Port
    Services        []Service
    Vulnerabilities []Vulnerability
    CPE             []string
    Agent           *SiriusAgent
}

type Port struct {
    Number   int    `json:"number"`   // Port number (22, 80, 443)
    Protocol string `json:"protocol"` // tcp, udp
    State    string `json:"state"`    // open, closed, filtered
}

type Vulnerability struct {
    VID         string  `json:"vid"`         // CVE ID
    Title       string  `json:"title"`
    Description string  `json:"description"`
    RiskScore   float64 `json:"risk_score"`  // CVSS score
}

Database Operations

import "github.com/SiriusScan/go-api/sirius/host"

// Add or update host
err := host.AddHost(hostData)

// Get host by IP
hostData, err := host.GetHost("192.168.1.100")

// Get all hosts
hosts, err := host.GetAllHosts()

// Delete host
err := host.DeleteHost("192.168.1.100")

Source Attribution

Track which tool discovered each finding:

import (
    "github.com/SiriusScan/go-api/sirius/host"
    "github.com/SiriusScan/go-api/sirius/postgres/models"
)

// Define scan source
source := models.ScanSource{
    Name:    "nmap",
    Version: "7.94",
    Config:  "ports:1-1000;template:quick",
}

// Add host with source attribution
err := host.AddHostWithSource(hostData, source)

// Get host with source history
hostWithSources, err := host.GetHostWithSources("192.168.1.100")

Message Queue

import "github.com/SiriusScan/go-api/sirius/queue"

// Publish message
err := queue.Publish("scan", scanMessage)

// Listen for messages
queue.Listen("scan", func(msg string) {
    // Process message
})

Key-Value Store

import "github.com/SiriusScan/go-api/sirius/store"

// Set value
err := store.SetValue(ctx, "key", "value")

// Get value
value, err := store.GetValue(ctx, "key")

// Delete value
err := store.DeleteValue(ctx, "key")

Development

Local Development with Replace Directive

For projects in the same repository or local development:

go.mod:

module github.com/SiriusScan/your-project

// Use local SDK for development
replace github.com/SiriusScan/go-api => ../go-api

require (
    github.com/SiriusScan/go-api v0.0.11
)

Benefits:

• Test SDK changes immediately
• No need to publish for every change
• Easy cross-project debugging
