4. Access Control Mechanisms:

   • Details access control models and techniques, including role-based access control (RBAC) and discretionary access control (DAC). This section also addresses authentication techniques and the management of access control policies.

5. Software Security:

   • Explores security issues related to software, including common vulnerabilities like buffer overflows, SQL injection, and cross-site scripting (XSS). The book also covers secure software development practices to mitigate these risks.

6. Security in Operating Systems:

   • Explains the role of the operating system in managing security, covering topics such as security policies, kernel security, and trusted operating systems. It also addresses the protection of system resources.

7. Security Management:

   • Covers key security management topics, such as risk assessment, security policies, and disaster recovery planning. This section provides practical approaches for implementing and managing security in organizational contexts.

8. Emerging Threats and Technologies:

   • Discusses recent trends and emerging threats, including malware, advanced persistent threats (APTs), ransomware, and the rise of cyber warfare. The book also examines cloud security, IoT security, and privacy issues.

9. Legal and Ethical Issues:

   • Reviews the legal frameworks governing computer security, including laws related to cybercrime, privacy, and intellectual property. Ethical issues surrounding surveillance, hacking, and encryption are also discussed.

10. Hands-on Exercises and Case Studies:

    • Includes real-world case studies and hands-on projects to illustrate security challenges and solutions. These exercises help bridge the gap between theory and practical application.
