Clarke spoke at a Tuesday event where she called for the swift appointment of a White House cyber czar and highlighted the urgent need for collaboration and information-sharing among federal agencies, academia, and industry. She will host two additional events this month sponsored by the National Cyber Security Alliance. They will take place Tuesday, Oct. 27 and Friday, Oct. 30. The events are primarily geared toward members and staff to promote good cyber hygiene on congressional networks.

Clarke said earlier this week that ignorance about safe computing "creates vulnerabilities right here on Capitol Hill." October is National Cybersecurity Awareness Month.
