The security community converged on London today for the kick off of Infosecurity Europe 2010.

Over the past few weeks we’ve been following almost 500 security voices on Twitter (ranging from vendors to journalists to bloggers). Each afternoon of the show we’ll be posting a summary of the top stories being talked about online.

We’re compiling this round-up using a range of social media tools such as Twitter Times, Twittermeme and Hootsuite.

Aside from multiple tweets on hangovers and collapsing keynote stages, here are the top stories from #Infosec today…

VMforce: VMWare and Salesforce announced plans to launch VMforce Enterprise Java Cloud, which will provide more than 6 million enterprise Java developers with an open path to cloud computing – @vmforce posted this blog from Steve Herrod.

McAfee: After last week’s flawed signature update McAfee said that it will offer compensation to home and home office users – and unveiled next generation firewall (along with @watchguardtech and @sonicwall).

Cisco expanded its content security arsenal: Cisco launched a data loss prevention and web security service as part of its Secure Borderless Network initiative (by @phil_V3).

There’s been lots of talk about the seizing of Gizmodo editor Jason Chen’s computers last Friday in California. And a number of security watchers also returned to an article from 2007, for insight in how to get ahead in information security.
