Department of Homeland Security Secretary Janet Napolitano acknowledged Friday her Luddite-like ways, despite the fact her position puts her in a critical leadership role when it comes to defending the nation's infrastructure from cyberattacks.

Napolitano said she does not use email "at all."

"For a whole host of reasons. So, I don't have any of my own accounts and that, you know, I'm very secure," Napolitano noted at a Washington conference about cyber security.

"Some would call me a Luddite but you know. But that's my own personal choice and I'm very unique in that regard I suspect," Napolitano added.

The Obama administration has been pushing Congress to revisit legislation that would have given DHS authority to enforce security standards. Legislation faltered earlier this year over concerns that it was too intrusive in requiring business to share data about intrusions, rather than it being voluntary.

In the meantime, an executive order is being drafted by the Obama administration that would help clarify security standards, Napolitano said. She said President Barack Obama has not reviewed it yet.

Napolitano said legislation would not dictate to companies how to run their security but rather would be a public-private partnerships to defend critical infrastructure.
