Fundamentals of Security introduces essential concepts from the CompTIA Security+ SY0-701 exam, crucial for understanding cybersecurity before delving into technical details. Cybersecurity professionals face challenges from both hackers and internal threats, often complicated by the tension between security and usability.
Using a home network example, the book illustrates the balance between convenience and security, as users frequently change complex default passwords to simpler ones, weakening security.
In an organizational context, balancing stringent security measures and productivity is key to preventing costly data breaches. The book defines critical terms like information security (protecting data) and information system security (protecting systems that process data).
Key security concepts covered include the CIA Triad (confidentiality, integrity, availability), non-repudiation (ensuring actions can't be denied), and authentication (verifying identity). The AAA framework (authentication, authorization, accounting) is explained for comprehensive understanding.
The book categorizes security controls into technical, managerial, operational, and physical, detailing types like preventative (firewalls), detective (intrusion detection), and corrective (backups). It also explores the Zero Trust model, which assumes no inherent trust and requires continuous verification.
Fundamentals of Security offers a clear, concise guide to these foundational concepts, essential for anyone pursuing the CompTIA Security+ SY0-701 certification and a career in cybersecurity.
