dbGSS

dbGSS is a software framework designed to provide integration of the Generic Security Services API (GSS-API) into database client–server communications. It enables authentication, data integrity, and confidentiality for database requests and responses by leveraging standard security mechanisms such as Kerberos and other GSS-API providers. By abstracting the security negotiation from database protocol logic, dbGSS aims to improve interoperability across different database systems and client platforms.

The architecture of dbGSS typically comprises a core security engine, protocol adapters, and plug-in modules for clients and servers. The core manages security context establishment, token exchange, and session lifecycle. Protocol adapters translate between the underlying database transport and the GSS-API calls, allowing drivers and servers to participate in a uniform security model. The design supports both middleware deployments and direct embedding as plugins within database engines or drivers, enabling secure configurations without altering application code.

In usage, dbGSS is adopted in environments where enterprise authentication policies require centralized credentials and, where possible, single sign-on. Administrators configure acceptable mechanisms, key material, and trust relationships, while developers rely on the library’s API to integrate with existing database drivers. The project emphasizes compliance with GSS-API standards and seeks to minimize performance overhead through efficient token handling and context caching.
