Are you an aficionado of IBM's RACF, or CA's ACF2 or Top Secret? Then you've come to the right place. This group is a LinkedIn Networking site for we dinos who have seen the mainframe declared dead at least twice, but still persevere and secure the big iron. This is a starting point for those who wish to share ideas, network with other security professionals, exchange technical advice, and generally help each other find opportunities (for employment, learning, or even a good laugh). We're not RACF-L (well, not yet, anyway) but I'm eager to begin a dialog that will help create an (unofficial) CA-ACF2-L and CA-TOPSECRET-L someday which can benefit the totality of the group. Until then, this place should do.
