Yesterday was Day 4 of the RSA Security Conference in San Francisco, and U.S. Department of Homeland Security Secretary Janet Napolitano stole the show by challenging the private sector and individuals alike to come up with a way to educate the public on the necessity of cybersecurity. Some details, and the rest of the fourth-day highlights behind the jump.

If you're interested in sharing your ideas with DHS, the deadline is April 30th 2010. More information is available here, and a full video of Secretary Napolitano's remarks is available here.

Other highlights:
  • EMC is teaming with Intel and VMware to show off a proof-of-concept for a compliant, secure, controlled cloud platform. Of course, they say it has a ways to go before it's commercial, if ever it does.
  • McAfee revealed that the hackers behind the recent Google attacks had access to the search engine's source code after breaking into employees' PC's remotely.
And that's Day 4 - relatively quiet compared to the last few days. Will the conference end with a bang or a whimper? We'll know for sure later today.
