Train Signal – Cisco CCNA Security 640-553:IINS raining


You cannot be a Cisco Network Administrator without knowing Cisco . Today, security knowledge is no longer a luxury, it is a necessity in nearly any IT position. Any job applicant, from the most experienced network admin to the entry level junior admin will be required to demonstrate a substantial amount of knowledge concerning security elements.

Passing the CCNA Security exam and proving your security knowledge is difficult. That’s why I have created this comprehensive course that shows you how to tackle the diverse security issues that you will face on the exam and in the real world.

As with all courses, this CCNA Security course presents the same combination of clearly explained theory and an abundance of "real world" lab examples using the new Security Device Manager (SDM) and the Command Line. This exciting course contains over 13 hours of video instruction where I break down network security theory as you work hands on with real Cisco routers & switches… and secure your own network!
