OpenVPN and the SSL VPN Revolution
IPSec VPNs are either too expensive or too difficult to use securely. IPSec is dense and contains too many options to be configured and administered securely by non-expert personnel. It also operates in kernel space providing the opportunity for catastrophic failure. OpenVPN rejects the complexity of IPSec by using the battle tested SSL/TLS protocol and cryptographic libraries to provide equal or better function in a simpler package. OpenVPN also operates in user-space increasing security and stability.

Understanding Virtual Private Networks
Enter another no-brainer application for the Internet environment: Virtual Private networks (VPN). It's a nobrainer in terms of its low-cost, easy-to-implement, and convenient solution for mobile and remote business networking. However, the technology it employs is nothing short of brilliant. This primer is written as a high-level overview of VPN to introduce less technical readers to this innovative WAN application. The publication is divided into four major sections: VPN History, VPN Technologies, VPN Applications, and VPN Products. Armed with this information, you should be well-poised for educated inquiry into the VPN service option for your own remote networking implementations.

VPN Project: Remote Access to a Novell Network
Our IT department has often been praised for accomplishing much with limited resources. We often put unique, specialized solutions in place while keeping costs as low as possible. Providing top service to our internal clients has always been our primary objective, and the majority of our resources and time would be allocated to ensure our clientele's visible requirements were met. As a result, some remote services had been put in place without adequate security measures. This problem was identified and we began to focus on tightening the security of our externally accessible IT services and resources. As a senior network administrator, I became project leader and was responsible for directing our security initiative to replace our existing remote access facilities with encrypted Virtual Private Networking (VPN) technology.

MPLS - VPN Services and Security
This paper will focus on the issues related to providing VPN services in a MPLS environment. The paper will discuss traditional routing and ATM in a service provider network. It will discuss the MPLS architecture and security issues and its benefits in providing a scalable connection oriented networking solution. This will provide the foundation for the discussion on providing scalable VPN services in a MPLS environment.

Network Based VPNs
This paper focuses on this particular type of VPN. First, it provides a short history on the evolution of VPNs, then it explains what is meant by Network based VPNs. To best present this concept, I will use a standard company network for which a CPE and a Network Based Solution is proposed and I will compare the 2 alternatives. Such an approach will allow identifying the differences in design and addressing some fundamental pre-requisites for the implementation of Network Based VPNs. I will review some important security issues to address when an ISP deploys such IP Service Switches. To finish up, we will be giving a list of the major PROs and CONs of Network Based VPNs.

Multiprotocol Label Switching Virtual Private Networks and the enterprise - Do they fit in the security model?
Multiprotocol label switching virtual private networks have gained press as a new service provider method to provide a secure path in the public Internet space. The question arises if this technology is the latest marketing ploy of the service providers or if this is a valid option for the enterprise within the security framework? If this is a valid option for the enterprise security framework is it a WAN technology only or does it have a place within the MAN or LAN environments? The first part in looking at the issue it to first understand if multiprotocol label switching virtual private network technology is a virtual private network and to determine how it works. A determination of what security is provided or not provided; also looking at what flaws it may have as a virtual private network. If the technology is found to be acceptable as a virtual private network, a look at how different enterprise customers can take advantage of this technology.
