Some cool Riverbed Upgrades and Additions

Gnomes on Redbull

When ever I hear of new products and features, I put the statement through the paces to see if it’s total BS, or something worthwhile. This morning, an email caught my eye. Riverbed made their announcement of upgrades and product line additions.

I love what Riverbed can do for their customers. I won’t lie. No product is perfect, but It’s just been too damn useful for think bad about anything of it. And when they bough CACE, and turned Wireshark into something even better, and that Riverbed Pilot is like Wireshark on crack with some redbull-fed gnomes for historical analytics… well I am even happier with the offerings.

Wish I went to DEFCON :(

Well another DEFCON is done.  I couldn’t make it this year due to work, finances, and life.  I miss all my DC buddies, especially my great friend @SecEvangelism!

You can’t look back, only forward.  My main reason for going to DEFCON, besides hanging with people I know online and rarely see in real life, is the lock picking village.  I truly enjoy teaching there (in a totally unofficial capacity).  Just hanging out in the air conditioning, picks in hand, fresh batches of new people all the time to talk to!

I did end up finding myself in the DEFCON20 Documentary for a few seconds.  I really wish they would have put more of an emphasis into the LPV in the movie.  It is a huge piece of DEFCON, where everybody who enters sees a little bit of applicable security (or lack their of) in their daily lifes.

Heck, I even had the documentary crew filming next to me when i was teaching some of the kids how to get out of handcuffs!

I hope to see all my security friends soon!  Maybe out here in NYC or DC sometime!
