Answer:
Nonobvious relationship
Explanation:
Cyber security can be defined as a preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
A nonobvious relationship can be defined as a process which typically involves combining data obtained or generated from multiple sources so as to help an individual and business detect hidden (obscure) connections that could help identify and unravel unscrupulous elements such as hackers, criminals or terrorists.
Just like its name, a nonobvious relationship exists between member nations or groups and it may not be exposed to nonmembers.
