If you are looking to get into Cyber Security be per causus. Look for a firm like IBM and not a department in a company. Hackers are light years ahead of CS departments. If you get hacked you can be fired. If you don't have 10 years experience and ccissp cert you won't be hired.

People just getting into any field of IT I would recommend trying to get an entry level position before thinking of going to college. Most employers want years of experience. Also it is making money even if as low as 8 dollars an hour vs pay tens of thousands of dollars and no experience.
