The Cisco CCNA Security curriculum provides a comprehensive overview of contemporary network security, helping Cisco Networking Academy students systematically prepare for the latest CCNA Security exam. While extensive on-line study resources are available, many students and instructors have requested a low-cost printed resource that can be used to study in places where Internet access may not be available. This booklet is that resource.
