Encrypting and Sharing a fideAS File Privately

Top 5 methods to secure a fideAS file privately

  1. Use fideAS enterprise with centralized key management

    • Enforce policies via the fideAS server and Active Directory integration so only authorized users/groups can decrypt files.
    • Enable role separation (security vs. system admins) and key archival for safe recovery.
  2. Strong encryption algorithms & proper key lengths

    • Use AES-256 for symmetric file encryption and RSA-⁄4096 for asymmetric operations where available.
    • Prefer modern modes (e.g., AES-GCM/CFB per product support) and up-to-date hash functions (SHA-256+).
  3. Protect keys with hardware tokens or PKCS#11 smartcards

    • Store private keys on smartcards/USB tokens or HSMs instead of local software key stores to prevent key extraction.
    • Require multi-factor use (token + PIN) for high-sensitivity files.
  4. Apply access controls and multi-person approvals

    • Use file/folder ACLs, group policies, and the “four-eyes” (two-person) principle for exceptionally sensitive documents.
    • Log and audit accesses; alert on anomalous decryption attempts.
  5. Secure backup, transport, and endpoint hygiene

    • Encrypt backups and removable media with the same fideAS policies; use signed packages for transport.
    • Keep client/server software patched, enforce endpoint antivirus/EDR, and require disk encryption (BitLocker/FileVault) to protect keys and temp data.
