Hi Stuart, I am involved as an IT architect in the deployment of SAS 9.4 M3 and asI am not a SAS expert, I had to build my expertise through a lot of readings. I successfully was able to develop a IT blueprint for sas deployment with an hybrid configuration mixing Linux VM and AIX LPAR. I noticed the graphic in your article (under https focus) and found it very pleasant and intresting as I had to create my own graphic based on my readings. Is there a way to get a copy of the drowing in VISIO or PPT format ? Thank you and keep on publishing security articles, regards Antoine
