Access Control Policy

1. Administrative Access

BlindVault infrastructure is divided into two distinct security zones:

Web API (BVWA) Zone

  • Access: Requires Multi-Factor Authentication (MFA) via the corporate Identity Provider.
  • Scope: Restricted to deployment and application monitoring.
  • Key Service (BVKS) Zone

  • Access: Limited to a single system administrator.
  • Method: Access is only possible via SSH Key-based authentication on a non-standard port.
  • Hardening: Password-based authentication is globally disabled. All SSH keys are stored on hardware-backed security modules where possible.
  • 2. Separation of Duties

  • Developers are restricted from the BVKS environment.
  • Administrative access to the host OS does not grant access to the plaintext KSK, which remains inside a protected, non-swappable memory segment of the BVKS process.
  • 3. Access Reviews

    Quarterly reviews are performed to ensure all SSH keys and MFA permissions match current personnel records.
