Overheard – WAN accelerator

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
It might take one or two hundred round trips to do a transaction. If that’s over a LAN and you have a delay or one or two milliseconds, nobody notices. Take that application and run it over a WAN … you get a delay of 10 to 20 seconds. That’s not acceptable.

Overheard – Active man in the middle attacks

Margaret Rouse Margaret Rouse Profile: Margaret Rouse

• The target is entirely controlled by the attacker, rather than being limited by the extent of the victim’s browsing activity

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
CoCo consists of 92 detailed security questions, some of which deal with endpoint protection and encryption…”Some questions had to be answered by people with a mix of skills — the network guys, the server team, the installation guys.

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
