CCNA Security: IPsec VPNs

Created on: May 16, 2012 3:23 PM by wiliu - Last Modified:  Mar 14, 2014 1:54 PM by Nicole Pfeiffer


The Cisco Learning Network proudly presents a series of three video lectures on the topic of “CCNA Security: IPsec VPN’s”


Are you studying for your CCNA Security exam? If so, or if you are considering a certification in security, one of the main topics that you will need to master is IPsec. In this recorded series, Brad Graham, who many of you may know from our study and discussion groups, answers some of the most frequent IPSec questions he encounters there including operation, configuration, and troubleshooting.


For those new to IPsec, it is designed to protect traffic between two endpoints and is commonly deployed for point-to-point and remote access connections. It was developed to support IPv4 which was not originally designed for data integrity or encryption. It is an important topic covered in the CCNA Security exam.
