The best way in my opinion to make money legally in cybersecurity is to protect your networks. Think of all the common practices of accounting, marketing, economics, and demographics. Also, have all your documents for the Internal Revenue Service in case of an audit. If the finances are not legal proven by paperwork you can lose your business or company.
