virtual private networks

This course examines all aspects of virtual private networks (VPN), which are networks that add privacy features to public networks such as the Internet to better serve mobile workers and other remote users. Various VPN issues are identified, including security threats from hackers and quality of service (QoS) concerns such as delay and jitter. Security issues are examined in depth and VPN solutions identified, including cryptography, authentication, and digital certificates. Security techniques and protocols are detailed.

The course continues with a survey of VPN tunnelling protocols such as PPTP, L2TP, and IPSec. Aspects of corporate VPNs are investigated, including the use and configuration of firewalls and proxy servers, especially as they relate to remote access and site-to-site connectivity over the Internet. The course concludes with a look at VPN service offerings, strategies, and deployment issues.

The key topics explored include:

• Introduction to VPNs
• Parameters and network classes of service
• Security and Cryptography
• Remote Access Authentication Protocols
• Tunnelling Protocols
• Firewall Use in VPNs
• VPN Services and Applications

This course is recommended for:

• Telecommunications professionals involved in the sale or implementation of VPN-related products or services
