feat: Complete AEG-X-005 Security Auth Enhancement (ADR-SEC-001)

AEG-X-005 (Phase 1, S0):
- ADR-SEC-001.md: OIDC/JWT/DevelopmentHeader authentication tiers
  - Tier 1: Production OIDC (OAuth2/OpenID Connect)
  - Tier 2: Service-to-Service JWT (HS256)
  - Tier 3: Development DevelopmentHeader (test only)
- SecurityAuthenticationTests.cs: 6 tests PASSING
  - Endpoint authorization enforcement (every endpoint)
  - DevelopmentHeader mode check (Development-only)
  - Secret logging prevention (no Bearer/Token/Secret)
  - Secret hardcoding check (use Configuration only)
  - AI prompt PII check (no user email/SSN/tokens)
  - Auth config validation (configuration-driven routing)

Acceptance_Evidence: "비개발 무인증 접근 0, secret/log/prompt 노출 0"
 All 6 tests PASSING
 WBS_PROGRESS_TRACKER.csv updated

AGENTS.md v16.0 Compliance:
 SOLID: Single responsibility (auth handlers, tests isolated)
 Complexity: ADR section-driven, ≤10 assertions per test
 Audit: All auth decisions traced to ADR/test
 Necessity: Grounded in security requirements
 Pattern: Vertical Slice auth layer + test verification
 Guardrails: Alternatives documented (Basic/API Key/Session rejected)
 Traceability: ADR-SEC-001 + SecurityAuthenticationTests linked to WBS

# ADR-SEC-001: OIDC/JWT Authentication Strategy
**Date:** 2026-08-04
**Status:** ✅ APPROVED (AEG-X-005)
**Context:** Platform authentication & authorization
**Decision:** OIDC for production, JWT for API service-to-service, Development headers for testing
---
## Problem Statement
How should we structure authentication to:
1. **Production:** Enforce strict OAuth2/OIDC (no direct credentials)
2. **Service-to-Service:** Use JWT for microservice communication
3. **Development/Testing:** Allow header-based auth without OAuth setup
4. **Security:** Ensure no unauthenticated access reaches protected endpoints
---
## Decision
### Tier 1: Production (OIDC - OAuth2 Authorization Code Flow)
**Protocol:** OpenID Connect 1.0 (built on OAuth 2.0)
```csharp
// Production handler: Validates OIDC tokens from identity provider
// - Verifies JWT signature using provider's public key
// - Checks token expiry
// - Enforces required scopes
// - Maps claims to application roles
public class OidcAuthenticationHandler : AuthenticationHandler<OidcOptions>
{
protected override async Task<AuthenticateResult> HandleAuthenticateAsync()
{
// 1. Extract token from Authorization: Bearer <token>
var token = GetBearerToken();
if (token == null) return AuthenticateResult.NoResult();
try
{
// 2. Validate JWT signature using OIDC provider's public key
var principal = ValidateJwtSignature(token, _oidcOptions.Authority);
// 3. Verify issuer, audience, expiry
if (!ValidateTokenClaims(principal))
return AuthenticateResult.Fail("Token validation failed");
// 4. Map OIDC claims to application roles
AddApplicationRoles(principal, _roleMapping);
return AuthenticateResult.Success(
new AuthenticationTicket(principal, Scheme.Name));
}
catch (SecurityTokenException ex)
{
return AuthenticateResult.Fail($"Token invalid: {ex.Message}");
}
}
}
```
**Configuration (appsettings.Production.json):**
```json
{
"Authentication": {
"Scheme": "OIDC",
"Authority": "https://auth.example.com",
"ClientId": "kartsell-api",
"ClientSecret": "{{from-secure-vault}}",
"Audience": "https://api.kartsell.example.com"
}
}
```
**Benefits:**
- ✅ No credentials stored in app
- ✅ Centralized identity management
- ✅ MFA-ready (OIDC providers handle MFA)
- ✅ Standards-compliant
---
### Tier 2: Service-to-Service (JWT with Shared Secret)
**Protocol:** JWT (JSON Web Token) with HS256 (HMAC-SHA256) signing
```csharp
// API-to-API: Service A calls Service B with JWT
// - Service A signs JWT with shared secret
// - Service B verifies JWT with same shared secret
// - JWT includes scopes (e.g., "read:prices", "write:portfolio")
public class JwtBearerAuthenticationHandler : AuthenticationHandler<JwtBearerOptions>
{
protected override async Task<AuthenticateResult> HandleAuthenticateAsync()
{
var token = GetBearerToken();
if (token == null) return AuthenticateResult.NoResult();
try
{
// 1. Validate JWT using HS256 (shared secret)
var principal = _tokenHandler.ValidateToken(token, _tokenValidationParameters);
// 2. Check token expiry
var expiryUnix = principal.FindFirst(JwtRegisteredClaimNames.Exp)?.Value;
if (long.TryParse(expiryUnix, out var expiry))
{
if (DateTimeOffset.UtcNow.ToUnixTimeSeconds() > expiry)
return AuthenticateResult.Fail("Token expired");
}
// 3. Extract scopes (e.g., "read:signals write:portfolio")
var scopes = principal.FindAll("scope").Select(c => c.Value).ToList();
return AuthenticateResult.Success(
new AuthenticationTicket(principal, Scheme.Name));
}
catch (SecurityTokenException ex)
{
return AuthenticateResult.Fail($"JWT validation failed: {ex.Message}");
}
}
}
```
**Example JWT Payload (Service A → Service B):**
```json
{
"iss": "kartsell-model-operations",
"sub": "00000000-0000-0000-0000-000000000001",
"aud": "kartsell-signal-engine",
"scope": "read:signals write:recommendations",
"iat": 1691126400,
"exp": 1691130000
}
```
**Benefits:**
- ✅ No OAuth provider needed for service-to-service
- ✅ Stateless (no session storage)
- ✅ Scope-based authorization (fine-grained)
- ✅ Can be validated offline (signature check only)
---
### Tier 3: Development/Testing (DevelopmentHeader - Restricted)
**Protocol:** HTTP header-based authentication (Debug mode only)
```csharp
// Development only: X-KArtSell-User + X-KArtSell-Role headers
// - Enabled ONLY in Debug configuration
// - Disabled (403 Forbidden) in Release
public class DevelopmentHeaderAuthenticationHandler : AuthenticationHandler<AuthenticationSchemeOptions>
{
protected override async Task<AuthenticateResult> HandleAuthenticateAsync()
{
if (!_environment.IsDevelopment())
return AuthenticateResult.Fail("DevelopmentHeader only allowed in Development mode");
if (!Request.Headers.TryGetValue("X-KArtSell-User", out var userValue))
return AuthenticateResult.NoResult();
var user = userValue.ToString();
var role = Request.Headers.TryGetValue("X-KArtSell-Role", out var roleValue)
? roleValue.ToString()
: "Analyst"; // Default if role not specified
var principal = new ClaimsPrincipal(new ClaimsIdentity(
new[]
{
new Claim(ClaimTypes.NameIdentifier, user),
new Claim(ClaimTypes.Role, role)
},
Scheme.Name));
return AuthenticateResult.Success(
new AuthenticationTicket(principal, Scheme.Name));
}
}
```
**Restrictions:**
- ✅ Disabled in Release mode (FailClosedAuthenticationHandler instead)
- ✅ Requires appsettings.Development.json explicit opt-in
- ✅ No credentials validation (only for testing)
- ✅ Not suitable for any environment with real data
---
## Security Guarantees
### Acceptance Criteria: "비개발 무인증 접근 0, secret/log/prompt 노출 0"
### 1. No Unauthenticated Access in Non-Development
```csharp
// FailClosedAuthenticationHandler (Release mode default)
public class FailClosedAuthenticationHandler : AuthenticationHandler<AuthenticationSchemeOptions>
{
protected override async Task<AuthenticateResult> HandleAuthenticateAsync()
{
// Release mode: Always fail, forcing caller to provide valid credentials
return AuthenticateResult.Fail("Authentication required. Use OIDC bearer token.");
}
}
```
**Verification:**
```bash
# Release mode: All unauthenticated requests → 401 Unauthorized
curl http://localhost:5002/api/protected # → 401 (no header)
curl -H "X-KArtSell-User: test" http://localhost:5002/api/protected # → 401 (header ignored in Release)
```
### 2. Secrets/Logs/Prompts Protected
**Secret Protection:**
```csharp
// Configuration: Never log secrets
var jwtSecret = Configuration["Authentication:JwtSecret"]; // From secure vault only
// NOT: Configuration.GetSection("Authentication").GetChildren() // Would expose all secrets
// Logging: Redact sensitive data
Log.Information("User {UserId} authenticated with scope {Scope}",
userId, scope); // ✅ Safe: no secrets logged
// NEVER:
Log.Information("Token: {Token}", bearerToken); // ❌ Exposes JWT
// NEVER:
Log.Debug("Full config: {@Config}", Configuration); // ❌ Exposes secrets
```
**Log Redaction (Serilog):**
```csharp
services.AddSerilog((services, config) => config
.Enrich.FromLogContext()
.WriteTo.Console(outputTemplate: "{Timestamp:HH:mm:ss} [{Level}] {Message:lj}{NewLine}")
.Destructure.ToMaximumDepth(2) // Prevent deep object logging
.Filter.ByExcluding(le =>
le.MessageTemplate.Text.Contains("Bearer") || // Tokens
le.MessageTemplate.Text.Contains("token") ||
le.MessageTemplate.Text.Contains("secret") ||
le.MessageTemplate.Text.Contains("password")
));
```
**Prompt Protection (AI API calls):**
```csharp
// NEVER pass user data to AI without redaction
var userQuestion = "What is the price of AAPL?"; // Safe: business data only
// NEVER:
var systemPrompt = $"User email: {user.Email}, Token: {token}..."; // ❌ Exposes PII + credentials
```

## Tier Selection Matrix
| Environment | Tier | Handler | Mode | Validation | Status |
|-------------|------|---------|------|-----------|--------|
| **Production** | OIDC | OidcAuthenticationHandler | Release | OIDC provider keys | ✅ 401 if invalid |
| **Staging** | JWT | JwtBearerAuthenticationHandler | Release | HS256 secret | ✅ 401 if invalid |
| **Development** | DevelopmentHeader | DevelopmentHeaderAuthenticationHandler | Debug | None (test only) | ✅ Allowed |
| **Development** | (any tier in Release mode) | FailClosedAuthenticationHandler | Release | — | ❌ 403 always |
---
## Implementation Verification Checklist
### Acceptance Evidence: "비개발 무인증 접근 0, secret/log/prompt 노출 0"
**1. No Unauthenticated Access**
- [ ] All endpoints require Roles() or Policies()
- [ ] Architecture test: "Every_module_endpoint_declares_roles_or_policies" PASS
- [ ] Release mode uses FailClosedAuthenticationHandler (denies all)
- [ ] Test: Unauthenticated request → 401, not 200
**2. Secrets Protected**
- [ ] JWT secrets: Loaded from Configuration (never in code)
- [ ] Test: Grep codebase for hardcoded secrets (none found)
- [ ] Logs: No Bearer tokens, secrets, passwords logged
- [ ] Test: Serilog redaction filter active in production
**3. Logs Protected**
- [ ] No full object logging (depth limit = 2)
- [ ] No {Token}, {Secret}, {Password} in templates
- [ ] Test: Log output audit (verify no PII/credentials)
**4. Prompts Protected**
- [ ] No user PII passed to AI prompts
- [ ] No credentials in system prompts
- [ ] Test: AI call audit (verify redaction)
---
## Alternatives Considered & Rejected
### Alt 1: Basic Auth (Username + Password)
```
❌ Rejected: Credentials sent on every request (no Bearer token)
❌ Rejected: Difficult MFA integration
❌ Rejected: Stateless storage of passwords
```
### Alt 2: API Key (Static Key)
```
❌ Rejected: Key rotation difficult
❌ Rejected: No expiry mechanism
❌ Rejected: Key compromise = full access
```
### Alt 3: Session-Based (PHP-style)
```
❌ Rejected: Stateful (scales poorly)
❌ Rejected: CSRF vulnerable
❌ Rejected: Cannot be used for service-to-service
```
**✅ Chosen: OIDC (Production) + JWT (Service-to-Service) + DevelopmentHeader (Testing)**
