The development of a virtual-machine monitor (VMM) security kernel for the VAX architecture is described. Particular focus is on how the system's hardware, microcode, and software are aimed at meeting A1-level security requirements while maintaining the standard interfaces and applications of the VMS and ULTRIX-32 operating systems. The VAX security kernel supports multiple concurrent virtual machines on a single VAX system, providing isolation and controlled sharing of sensitive data. Rigorous engineering standards were applied during development to comply with the assurance requirements for verification and configuration management. The VAX security kernel was developed with a heavy emphasis on performance and on system management tools. The kernel performs sufficiently well that all of its development can be now carried out in virtual machines running on the kernel itself, rather than in a conventional time-sharing system
