Please. Try running the A/UX CMW version. Validated B1(+) level system. Also had a secure X Window system (no cut-and-paste between windows with different security labels, etc.). My first "real" job was with SecureWare, the company that wrote it (and similar systems for HP, DEC, Tektronix, etc.). And, yes, we wrote the C2 subsystem for SCO Unix. People who want to run C2 & B-level systems almost never know what they are getting into. Ken Seefried, CISSP
