Security Checklist

Security checklist for enterprise deployments.

Security best practices for RustFS. Review this checklist during deployment to ensure system security and reliability.

Authentication & Access Control

  • Use S3-Compatible Key Authentication RustFS uses AWS Signature V4. Make sure that all requests are signed with a valid access key and secret key.

  • Policy-Based Access Control Define access policies based on the principle of least privilege. Explicitly define allowed operations; deny all others by default.

Encryption (TLS/SSL)

  • Enable TLS/SSL Configure valid TLS certificates. We recommend using different certificates for external and internal access, and enforcing TLS 1.2+.

  • Certificate Management Use certificates from trusted CAs. Protect private keys with strict file permissions.

  • Multi-Domain and Cipher Suites Use separate certificates for each domain. Use strong key algorithms (for example, RSA 2048-bit or ECDSA P-256).

Credential Protection

  • Change Default Credentials Never keep the example placeholders (<your-access-key> / <your-secret-key>) in production. Set a unique access key and a strong, random secret — e.g. generate one with openssl rand -base64 24 — immediately after initialization.

  • Secure Storage Do not hardcode credentials. Use environment variables or secrets management systems (e.g., Kubernetes Secrets).

Logging & Auditing

  • Enable Audit Logs Export audit logs to external systems (HTTP Webhook, Kafka, ELK, Splunk).

  • Log Collection Collect logs with standard tools (journald, Docker, Kubernetes) and analyze them with ELK or Grafana Loki.

  • Monitoring and Alerts Set alerts for abnormal behavior (login failures, unusual access patterns, mass deletions).

  • Observability Monitor request latency to identify performance issues.

API Security

  • Restrict Network Access Restrict access to the S3 API (port 9000) and Console (port 9001) using firewalls or security groups.

  • Network Isolation Use reverse proxies (e.g., Nginx) instead of exposing storage nodes directly.

  • Close Unnecessary Ports Disable unused ports and do not expose management interfaces to the public internet.

WORM Compliance

  • Versioning and Object Lock Enable versioning and object locking to meet regulatory requirements.

Updates

  • Apply Patches Regularly check for and apply RustFS updates.

  • Non-Disruptive Upgrades Use the rolling restart process for zero-downtime upgrades.

  • OS and Dependencies Keep the operating system and dependencies (e.g., OpenSSL) updated.


Review this checklist regularly to maintain a secure RustFS deployment.
