- Aimed At
-
Technical professionals who implement, test, support, or trouble-shoot IPSec v2 and related protocols. The course will also benefit technical sales and sales support personnel needing a more in-depth understanding of IPSec v2 to support secure networks and the needs of certain government agencies.
- Prerequisites
-
To get the most out of the course, you should have a strong working knowledge of the IP protocol suite and an understanding of basic security concepts such as encryption, tunneling, and key management. These topics will be reviewed only briefly in this course.
- Course in a Nutshell
-
This is an in-depth, heavily hands-on workshop on the technical aspects of IPSec v2 with special emphasis on protocols, implementation, and operations as described in RFC 2401 and 2412. It includes four protocol analyzer labs that will help you understand the internal workings of IPSec v2. The labs cover Layer 2 Tunneling Protocol version 3 (L2TPv3), Encapsulating Security Protocol (ESP), Authentication Header (AH), and Internet Key Exchange, and Internet Security Association Key Management Protocol (IKE/ISAKMP).
- Customize It!
-
Customize this course to your group’s requirements at little-to-no added cost. We can teach distinct versions of this course tailored for audiences such as network engineers and technicians, equipment/application designers, and less technical audiences such as managers, sales/marketing specialists, and operations/support personnel. The specific topics discussed in the course, as well as the depth of treatment for each, can also be tailored to your need.
