Answer:
c. NSTISSI No. 4011
Step-by-step explanation:
NSTISSI is an acronym for National Security Telecommunications and Information Systems Security Institute.
It is one of the standards set by the Committee on National Security Systems (CNSS), an intergovernmental agency saddled with the responsibility of setting policies for the security of the IT (information technology) security systems of the United States of America.
NSTISSI No. 4011 presents a comprehensive model for information security and is becoming the evaluation standard for the security of information systems.
Generally, all information technology institutions and telecommunications providers are required by law to obtain a NSTISSI-4011 certification or license because it is a standard for Information Systems Security (INFOSEC) professionals.
