Private API Channel Configuration

Configure DeepWikiOpen to use private API channels for enhanced security and control.

API Gateway Setup

# api-gateway-config.yaml
apiVersion: v1
kind: ConfigMap
metadata:
  name: deepwikiopen-api-config
data:
  api-config.json: |
    {
      "channels": {
        "private": {
          "endpoint": "https://api-internal.company.com/deepwiki",
          "protocol": "https",
          "port": 443,
          "timeout": 30000,
          "retryPolicy": {
            "maxRetries": 3,
            "backoffMultiplier": 2
          }
        }
      },
      "routing": {
        "defaultChannel": "private",
        "fallbackEnabled": false
      }
    }

Environment Configuration

# .env.production
DEEPWIKI_API_CHANNEL=private
DEEPWIKI_API_ENDPOINT=https://api-internal.company.com/deepwiki
DEEPWIKI_API_KEY_ROTATION_DAYS=30
DEEPWIKI_API_RATE_LIMIT=1000
DEEPWIKI_API_BURST_LIMIT=2000

Network Isolation

# network-policy.yaml
apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
  name: deepwikiopen-api-isolation
spec:
  podSelector:
    matchLabels:
      app: deepwikiopen
  policyTypes:
  - Ingress
  - Egress
  egress:
  - to:
    - namespaceSelector:
        matchLabels:
          name: api-gateway
    ports:
    - protocol: TCP
      port: 443

Custom Base URL Setup

Configure custom base URLs for corporate proxy environments.

Proxy Configuration

// config/proxy.js
module.exports = {
  production: {
    baseUrl: process.env.CORPORATE_BASE_URL || 'https://deepwiki.company.com',
    proxy: {
      host: process.env.PROXY_HOST || 'proxy.company.com',
      port: process.env.PROXY_PORT || 8080,
      auth: {
        username: process.env.PROXY_USERNAME,
        password: process.env.PROXY_PASSWORD
      },
      protocol: 'https'
    },
    bypassList: [
      'localhost',
      '127.0.0.1',
      '.company.internal'
    ]
  }
}

Reverse Proxy Setup (NGINX)

# nginx.conf
upstream deepwikiopen_backend {
    least_conn;
    server backend1.internal:8080 weight=5;
    server backend2.internal:8080 weight=5;
    server backend3.internal:8080 weight=5;
    
    keepalive 32;
    keepalive_requests 100;
    keepalive_timeout 60s;
}

server {
    listen 443 ssl http2;
    server_name deepwiki.company.com;
    
    ssl_certificate /etc/nginx/certs/company.crt;
    ssl_certificate_key /etc/nginx/certs/company.key;
    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_ciphers HIGH:!aNULL:!MD5;
    
    location / {
        proxy_pass https://deepwikiopen_backend;

        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        
        # Corporate headers
        proxy_set_header X-Company-User $http_x_company_user;
        proxy_set_header X-Company-Department $http_x_company_department;
        
        # Security headers
        add_header X-Content-Type-Options nosniff;
        add_header X-Frame-Options DENY;
        add_header X-XSS-Protection "1; mode=block";
        add_header Strict-Transport-Security "max-age=31536000; includeSubDomains";
    }
}

Authorization Mode Configuration

Implement robust authorization modes for enterprise environments.

RBAC Configuration

# rbac-config.yaml
apiVersion: v1
kind: ConfigMap
metadata:
  name: deepwikiopen-rbac
data:
  roles.json: |
    {
      "roles": {
        "admin": {
          "permissions": ["read", "write", "delete", "admin"],
          "resources": ["*"]
        },
        "developer": {

        }
      },
      "defaultRole": "viewer",
      "superAdmins": ["admin@company.com"]
    }

  }, (issuer, profile, done) => {
    // Map corporate groups to DeepWiki roles
    const roles = mapCorporateGroups(profile.groups);
    return done(null, {
      id: profile.id,
      email: profile.email,
      roles: roles,
      department: profile.department

      maxAge: 8 * 60 * 60 * 1000, // 8 hours
      sameSite: 'strict'
    }
  }
};

// auth/api-key-manager.js
class EnterpriseAPIKeyManager {
  constructor(config) {
    this.rotationDays = config.rotationDays || 30;
    this.keyVault = config.keyVault;
  }
  
  async rotateKeys() {
    const keys = await this.keyVault.listKeys();
    const now = Date.now();
    
    for (const key of keys) {
      if (now - key.createdAt > this.rotationDays * 24 * 60 * 60 * 1000) {
        // Generate new key
        const newKey = await this.generateSecureKey();
        
        // Store in vault
        await this.keyVault.store({
          id: key.id,
          key: newKey,
          createdAt: now,
          previousKey: key.key,
          rotatedAt: now
        });
        
        // Notify administrators
        await this.notifyKeyRotation(key.id);
      }
    }
  }
  
  async generateSecureKey() {
    const crypto = require('crypto');
    return crypto.randomBytes(32).toString('base64');
  }
}

Compliance Considerations

GDPR Compliance

// compliance/gdpr.js
class GDPRCompliance {
  constructor() {
    this.consentManager = new ConsentManager();
    this.dataProcessor = new PersonalDataProcessor();
  }
  
  async handleDataRequest(userId, requestType) {
    switch (requestType) {
      case 'access':
        return await this.exportUserData(userId);
      case 'rectification':
        return await this.correctUserData(userId);
      case 'erasure':
        return await this.deleteUserData(userId);
      case 'portability':
        return await this.exportPortableData(userId);
      default:
        throw new Error('Invalid request type');
    }
  }
  
  async anonymizeData(data) {
    // Implement data anonymization
    const anonymized = {
      ...data,
      email: this.hashEmail(data.email),
      name: 'ANONYMIZED',
      ipAddress: this.anonymizeIP(data.ipAddress)
    };
    return anonymized;
  }
}

Audit Logging

// compliance/audit-logger.js
class AuditLogger {
  constructor(config) {
    this.storage = config.storage;
    this.encryption = config.encryption;
  }
  
  async log(event) {
    const auditEntry = {
      timestamp: new Date().toISOString(),
      userId: event.userId,
      action: event.action,
      resource: event.resource,
      result: event.result,
      ipAddress: event.ipAddress,
      userAgent: event.userAgent,
      department: event.department,
      metadata: event.metadata
    };
    
    // Encrypt sensitive data
    const encrypted = await this.encryption.encrypt(auditEntry);
    
    // Store with integrity check
    await this.storage.store({
      data: encrypted,
      hash: this.calculateHash(encrypted),
      signature: await this.sign(encrypted)
    });
  }
  
  async generateComplianceReport(startDate, endDate) {
    const entries = await this.storage.query({
      startDate,
      endDate
    });
    
    return {
      summary: this.summarizeActivity(entries),
      accessPatterns: this.analyzeAccess(entries),
      anomalies: this.detectAnomalies(entries),
      privilegedActions: this.filterPrivileged(entries)
    };
  }
}

Security Best Practices Summary

  1. Zero Trust Architecture: Never trust, always verify
  2. Principle of Least Privilege: Grant minimum required permissions
  3. Defense in Depth: Multiple layers of security controls
  4. Regular Security Audits: Quarterly penetration testing
  5. Incident Response Plan: Documented and tested procedures
  6. Encryption Everywhere: In transit and at rest
  7. Continuous Monitoring: Real-time threat detection
  8. Patch Management: Automated security updates
  9. Access Reviews: Regular audit of user permissions
  10. Security Training: Regular employee security awareness
