The Framework Core consists of
five concurrent and continuous Functions—Identify, Protect, Detect, Respond, Recover.
This Framework is designed to protect critical infrastructure of the United States (utilities, police, fire, and other government functions)
Small business owners can learn some things as to what to do in the primary function of the framework: to Identify your risk and develop organizational understanding to handle this.
It seems that this framework is not very specific, and may be helpful to some companies which have not put the time into making Cybersecurity a priority.
