What is the primary focus of Information Systems Security Management?

The primary focus of Information Systems Security Management is ensuring the confidentiality, integrity, and availability of information systems. This triad, often referred to as the CIA triad, represents the foundational principles required to protect information assets.

Confidentiality ensures that sensitive information is accessed only by authorized individuals, which is crucial in preventing data breaches and unauthorized disclosures. Integrity involves maintaining the accuracy and completeness of data, ensuring that it is not altered or tampered with by unauthorized parties. Availability ensures that information and resources are accessible to authorized users when needed, preventing downtime that could disrupt business operations.

Each of these elements is essential for safeguarding an organization’s information assets against various threats, both internal and external. Thus, focusing on the CIA triad directly addresses the core responsibilities of Information Systems Security Management, making it the correct answer.
