Do you mind if I ask what kind of networks you and your client have?
"room-temperature superconducting artificial neural network with the ability to learn" :rofl3
:popcorn
Actually the networks I work with are quite homogeneous; like the Internet and the world. The client is an IT outsourcer so they basically have a little bit of everything, kinda "your mess for less" - some of it is very-archaic by today's standards (e.g. VAX).
Desktops mostly Windoze. Servers are a mix of Windoze/Linux/Unix. Lot's of VMware virtualization thrown in.
The company I work for makes management/monitoring software for IT -- including for security. My background is security, though these days I work as an escalation point for Support to insure we meet our SLAs (service level agreements) with our clients and do not have outages such as the one being experienced with PSM.
Before that I was a security conslutant (typo intended for clarification of meaning; i.e. have laptop/will travel). Prior to that, I was the chief security officer for a couple of state agencies within TX.
:rant
When I ran information security at the Comptroller's Office, we never had any security breaches - especially like they recently had where they exposed taxpayer records in the open for several years. But then we were certified IT professionals and not the political must-hires that Susan Combs brought in when she was elected. The folks she hired might have known alot of managerial buzzwords but they couldn't spell PC or LAN... They also had no concept of GASP - other than gasping for air when something unexpected by them happened, i.e. jaw drop.
