Cyber systems didn't get much love from the H/P kids back in the day :O http://phrack.org/issues/18/5.html
That said; NOS is one of the few mainframe systems ever really discussed in Phrack... MVS/TSO and VM/CMS you also see occasionally, but beyond that, it seems like most of the G-files were focused on midrange systems ... UNIX, VMS, MPE, PRIMOS, TOPS and the like. Very little discussion of many of the mainframe vendors ... There are a few Youtube videos where I guess people have done presentations at Defcon or something recently, about mainframe security ... kind of neat to watch ... of course, the z/OS they show has got all kinds of POSIX stuff grafted onto it and ... it's fairly indistinguishable from something older that I would recognize... like MVS 3.8J :O Best, Sean On Wed, Sep 16, 2015 at 2:29 PM, Paul Koning <paulkon...@comcast.net> wrote: > > > On Sep 16, 2015, at 2:10 PM, Chuck Guzis <ccl...@sydex.com> wrote: > > > > This brings up something that's always baffled me. > > > > Why does a user's (or worse, the entire system's) files have to be > immediately accessible to any application wanting to take a look. > > > > Take a legacy example, SCOPE or NOS on a CDC mainframe. ... > > Just remember that those older systems may well have had any number of > security issues of their own.
