What does "information security" focus on?

Information security primarily focuses on the protection of information systems from unauthorized access. This encompasses a wide range of practices and strategies aimed at safeguarding sensitive data, ensuring confidentiality, integrity, and availability. Organizations implement information security measures to defend against various threats, including cyberattacks, data breaches, and insider threats. By emphasizing the security of information systems, businesses can protect critical data assets, comply with regulations, and maintain trust with customers and stakeholders.

The other options do not capture the core focus of information security: integrating IT systems can enhance overall efficiency, speed of data retrieval processes addresses performance issues, and reducing IT costs may improve financial outcomes, but none directly relate to the fundamental goal of safeguarding information from unauthorized access. Hence, option B accurately reflects the essential purpose of information security.
