Introduction

Welcome to CCNA Security! Scott Empson had an idea to provide a summary of his engineering journal in a portable quick reference guide. The result is the Portable Command Guide series. These small books have proven to be very valuable for anyone studying for Cisco certifications or as a handy quick reference resource for anyone tasked with managing Cisco infrastructure devices.

The CCNA Security Portable Command Guide covers the security commands and GUI steps needed to pass the 640-554 IINS (Implementing Cisco IOS Network Security) certification exam. The guide begins by summarizing the required fundamental security concepts. It then provides the CLI commands and the Cisco Configuration Professional GUI screenshots required to secure an ISR. Examples are included to help demonstrate the security-related configuration.
