Barack Obama is still in the hunt for his Cyber Czar and maybe this could be the person for that position. According to reports Window Snyder (Go figure) is leaving for a start-up company. I guess Obama will still be fishing for his Cyber Czar.

Window Snyder, the head of security at Mozilla Corp., will resign her position at the end of the year, she said in a blog post Wednesday.

“I am sad to be leaving, but I am excited to go work on something I have always been passionate about,” Snyder wrote in the Mozilla security blog. “I wish I could tell you about it now, but that will have to wait for a while.”

She joined Mozilla in September 2006 from Microsoft, where she was a security strategist and worked on Microsoft’s security-focused Windows XP Service Pack 2 update.

Security has become more important for Mozilla as its Firefox browser has gained more users, making it a more attractive target for malicious hackers. Just last week it was being targeted by a new Trojan that tries to steal online banking passwords, according to security company BitDefender.

“It’s impossible to build a perfectly secure browser,” Snyder told Computerworld in an interview earlier this year. “That’s not the goal. The goal is to build the safest browser we can. It’s an ongoing process. It’s not a goal where we’ll say, ‘OK, we’re done.’”

The good news is she leaving Mozilla’s security in capable hands, naming several colleagues who will assume her duties.
