Description

The introduction explains that information security (InfoSec) has become a critical concern in the digital age because individuals, organizations, and governments increasingly depend on computers, networks, and digital information. As technology advances, security threats such as unauthorized access, data theft, malware, and system attacks continue to evolve, making effective protection strategies essential.

The authors introduce information security as the practice of protecting information and information systems from threats while ensuring that data remains reliable, available, and accessible to authorized users. The introduction emphasizes that security is not only a technical issue but also involves people, processes, policies, and organizational awareness.
