Getting Started

Get security scanning working in your .NET API in under 5 minutes.

Complete Data Isolation

Primus Security runs entirely within your application. No code, secrets, or scan results are ever transmitted to external servers. All scanning happens locally.

---

1. Install Package

dotnet add package PrimusSaaS.Security

---

2. Add Using Statement

using PrimusSaaS.Security;
using PrimusSaaS.Security.Core;

---

3. Register in Program.cs

var builder = WebApplication.CreateBuilder(args);

// Add Primus Security
builder.Services.AddPrimusSecurity(opts =>
{
    builder.Configuration.GetSection("PrimusSecurity").Bind(opts);
    opts.EnableSecretDetection = true;
    opts.EnableDependencyScanning = true;
    opts.EnableStaticAnalysis = true;
});

var app = builder.Build();

// Verify data isolation on startup (optional)
var verification = PrimusSecurityExtensions.VerifyDataIsolation();
if (!verification.IsFullyIsolated)
{
    Console.WriteLine("Warning: Security module not fully isolated");
}

app.MapControllers();
app.Run();

---

4. Configure appsettings.json

{
  "PrimusSecurity": {
    "EnableSecretDetection": true,
    "EnableDependencyScanning": true,
    "EnableStaticAnalysis": true,
    "EnablePolicyValidation": true,
    "FailOnCritical": false,
    "CveDatabasePath": "data/cve-database.db"
  }
}

---

5. Add Security Controller (Optional)

For API-based scanning, add a controller:

[ApiController]
[Route("api/[controller]")]
public class SecurityController : ControllerBase
{
    private readonly ISecurityScanner _scanner;

    public SecurityController(ISecurityScanner scanner)
    {
        _scanner = scanner;
    }

    [HttpPost("scan")]
    public async Task<IActionResult> Scan([FromBody] ScanRequest request)
    {
        var result = await _scanner.ScanAsync(request.Path);
        return Ok(result);
    }

    [HttpPost("detect-secrets")]
    public async Task<IActionResult> DetectSecrets([FromBody] DetectSecretsRequest request)
    {
        var result = await _scanner.ScanContentAsync(request.Content, request.FileName);
        return Ok(result);
    }
}

---

6. Test It

# Start your API
dotnet run

# Test security status
curl http://localhost:5000/api/security/status

# Test secret detection (AWS Access Key ID format)
curl -X POST http://localhost:5000/api/security/detect-secrets \
  -H "Content-Type: application/json" \
  -d '{"content": "aws_access_key_id = AKIAIOSFODNN7EXAMPLE", "fileName": "credentials"}'

Notes:

• content is required. Empty or missing content returns HTTP 400.

Expected Response:

{
  "scanId": "...",
  "findings": [
    {
      "ruleId": "SEC001",
      "severity": "Critical",
      "title": "Hardcoded Secret: AWS Access Key ID",
      "line": 1
    }
  ],
  "passed": false
}

---

That's It!

You now have security scanning running locally. Your API can:

• Detect hardcoded secrets (AWS, Azure, Stripe, etc.)
• Scan dependencies for CVE vulnerabilities
• Enforce security policies
• Generate PDF/HTML reports
