HUD Secure Systems refer to a suite of online, protected systems used by the U.S. Department of Housing and Urban Development (HUD) for managing multifamily housing data, property management, tenant certifications, and housing assistance payments. These systems require user registration and role- based access, including Coordinators and Users, to ensure secure handling of sensitive information. Key HUD Secure Systems include:

• APPS (Active Partners Performance System) for business partner registration and vetting.
• EIV (Enterprise Income Verification System) providing income verification data.
• iMAX (Integrated Multifamily Access Exchange) for transmitting tenant certifications and vouchers.
• TRACS (Tenant Rental Assistance Certification System) for subsidy contract and tenant data management.

Users and organizations must register, designate coordinators who assign permissions, and obtain secure credentials (M-ID) to access these systems. Security protocols emphasize protecting passwords, safeguarding sensitive data, encryption requirements for portable devices, and authorized remote access only. HUD also enforces compliance with Privacy Act regulations and immediate reporting of security breaches.
