You know I read about this story this morning, and it actually contained Mojtaba Ahmadi's official title which I can't remember right now but it certainly wasn't "cyberwarfare czar". That makes him sound like some fuckin' cocaine-fueled warlord demanding ransoms out of a cave, and not a government official.
An ombudsman, in Canada at least, is an independent official appointed to oversee and investigate the provincial government based on feedback from the public. Every province has their own ombudsman.
I think the idea behind the "czar" title is that the official has more authority to change the underlying organization and it lets the government pretend it's not a giant bureaucracy.
