Orange County Tech-Security Conference

One day event, relax, easy and interesting. This is a smalll scale security conference, only have around 30 vendors for exhibition and about 8 keynotes speakers.
The conference place is doubletree hotel in orange, in the heart of orange county. Easy to find but difficult to park. It is better to call the hotel first to get directions for parking.
Most of the presentations are good, and the most impressive one was given by Peter Bybee, the CEO of Security on Demand. His speech is well organized, easy to understand, good coverage for current IT environment and future cloud computing. If I ever need any service, I will go to him.
I took some pictures with my iPhone while I was sitting next to the IT chief of Cal State Fullerton, but unfortunately I lost them all due to an unsucessful firmware upgrade.

DEATH OF PST FILE - a white paper

Is pst file a challenge for you? Maybe yes. If you are still on outlook 2000 or office xp, the 2gb quota must cause some chaos in your organization, because there are more and more multimedia files been send and received by outlook. And usually, their size is no small, like high resolution pictures, video clips, pdf files, etc.
Even with the 20gb quota in outlook 2003 and 2007 (outlook 2010 is better, size can grow up to 50gb), it still be filled up quickly. One of our designer filled up her 20gb in less than 45 days, even before the scheduled archive start working.  Anyway, read this white paper is help for your pst file security:
