The chapter discussed how the security paradigm is changing and that security solutions today
are no longer product based. Instead, they are more solution oriented and designed with business objectives in
mind. The chapter also discussed the core principles of security??”the CIA triad of confidentiality, integrity, and
availability??”followed by brief discussion of aspects of security policies: standards, procedures, baselines,
guidelines, and various security models. The chapter takes a detailed look at the perimeter security issue and
the multilayered security approach. The chapter concludes with the Cisco security wheel paradigm involving five
cyclical steps.
