Distributed File System - Security and Privacy

Authentication

  • Kerberos: Strong authentication
  • Token-based: Delegation tokens for jobs
  • User/Group: POSIX-style permissions
  • Service Authentication: Inter-service auth

Authorization

  • POSIX Permissions: User, group, other (rwx)
  • ACLs: Fine-grained access control
  • Quotas: Per-user/group storage limits
  • Namespace Isolation: Separate namespaces

Encryption

  • At Rest: Transparent encryption zones
  • In Transit: TLS for RPC and data transfer
  • Key Management: KMS integration
  • Per-File Encryption: Different keys per file

Data Privacy

  • Data Isolation: Tenant separation
  • Audit Logging: Track all operations
  • Data Deletion: Secure deletion
  • Compliance: GDPR, HIPAA support

Network Security

  • Firewall Rules: Restrict access
  • VPC Isolation: Private networks
  • DDoS Protection: Rate limiting
  • Intrusion Detection: Monitor anomalies

Best Practices

  • Enable Kerberos authentication
  • Use encryption zones for sensitive data
  • Regular security audits
  • Principle of least privilege
  • Monitor access patterns

This security guide ensures the distributed file system protects data and maintains compliance.
