Data security: Whose job is it really?

By Andrew Jaquith
Despite years of investments in technology and processes, protecting enterprise-wide data remains a maddeningly elusive goal for chief information security officers (CISOs). Software-as-a-service (SaaS), Web 2.0 technologies, and consumerized hardware increase the number of escape routes for sensitive information. Regulations, statutes, and contractual expectations drown CISOs in audit requests and ratchet up the pressure to do something about the problem.

“The dean of the security deep thinkers,” “security luminary, ” and “risk-management pioneer” are all phrases that have been used to describe Dan Geer. Considered one of the foremost leaders in information security, his resume includes time as president and chief scientist at Verdasys Inc, a critical role in Project Athena at MIT, and a now famous firing from @Stake for co-writing a paper warning that a Microsoft monoculture threatened national security.
These days Geer, a 2009 CSO Compass Award winner, is CISO with In-Q-Tel, a non-profit venture capital firm that invests in security technology in support of the intelligence community. Geer recently spoke with CSO [csoonline.com] and explained why, despite all he has accomplished in his past, his sights are still set toward the future of security. Read the full Q&A interview.

In my appearance on the ‘Partial Disclosure Dilemma’ Panel at SOURCEBoston this year, I found myself surrounded by great minds who most certainly do not think alike.  While there was some agreement and common ground between all parties on the dais, namely wanting to make the Internet safer and protecting people, there was little agreement on the best way to accomplish that goal.
