Blume: Revenue working to restore credibility

The director of South Carolina's tax collection agency says the department is working to restore its credibility following last fall's massive hacking of taxpayers' personal data.

Bill Blume said Tuesday the Department of Revenue has finished encrypting stored data and outfitting laptop computers to require a second password from workers logging into the system remotely. Those are the two things that computer forensic firm Mandiant determined could have prevented the theft.

Blume spoke about the agency's progress at Gov. Nikki Haley's Cabinet meeting.

Other recommendations by Mandiant are under way. All should be completed by next summer.

Blume says the agency's new focus on security includes rules barring employees from using their computers during lunch or after hours for anything not business-related.
