Cisco is one of the premier vendors for network equipment and certifications. With their line of security appliances and security intelligence, Cisco has become a one-stop-shop for all your needs, from routers and switches to network security appliance for threat prevention and mitigation. The CCNA Security (210-260) certification validates whether a network security professional is able to identify, prevent, and mitigate existing and newly emerging threats and vulnerabilities using Cisco's switches, routers, and security appliances on the network infrastructure.

This book teaches you the basic to advanced stages of security configurations of the Cisco switches, routers and the Adaptive Security Appliance (ASA), from understanding key concepts to the configuration and implementation of the devices on the network. The hands-on approach ensures that you get the experience you need to be a network security professional.

By the end of this book, you'll be able to understand the concepts of both offensive and defensive security, identify and mitigate threats and vulnerabilities, secure a network using Cisco switches and routers, and configure and deploy the Cisco Adaptive Security Appliance (ASA).
