The IT security field today is wide open: anyone can hang out a shingle and declare him/herself a security pro. That may change in the U.S., in light of the Cyber Security Act of 2009, which will place a massive mantle of regulation on companies that provide "critical network infrastructure" and requires cybersecurity professionals to be certified and licensed.

Prepare for a shake-up in the security industry if this law passes. In the beginning, it would only be illegal to engage in the business of cybersecurity or be employed as a cybersecurity provider if you provide those services to federally designated "critical infrastructure networks," but we all know there's a good chance that would eventually expand to cover all networks.
