VPN Training Fundamentals

Duration: 2-3 days

Introduction

A VPN is a communications environment in which access is controlled to permit peer connections only within a defined community of interest, and is constructed though some form of partitioning of a common underlying communications medium, where this underlying communications medium provides services to the network on a non-exclusive basis.

Virtual private networks have become an essential part of today’s business networks, as they provide a cost-effective means of assuring private internal and external communications over the shared Internet infrastructure. Virtual Private Networks: Technologies and Solutions is a comprehensive, practical guide to VPNs.

VPN Fundamentals includes VPN concepts and architectures,an in-depth examination of advanced features and functions such as tunneling, authentication, access control, VPN gateways, VPN clients, and VPN network and service management. This course presents the various technology components, concrete solutions, and best practices you need to deploy and manage a highly successful VPN.
