Sorting Through the Hype of Ubiquitous Secure Remote Access and SSL VPNs If I told you that I could give you a car, exactly like the car you already own with the exception that it gets 1,000 miles/gallon and would have no maintenance costs for 10 years, would you start asking me about adding cup-holders? I doubt it-I sure wouldn’t. However, if I told you that I could replace your existing remote access solution with one that provides the exact same capability, but has increased deployment flexibility, increased security options, a lower TCO and faster ROI-I am constantly questioned about whether it can provide "ubiquitous" access. The short answer is "No." The real answer is "No. You shouldn’t expect it to, don’t really want it to and don’t really need it."

Communicating Through The Tunnel Information security has emerged as one of the most important segments of the computing industry. Corporations around the world are finding themselves adopting new Internet based approaches to enhance communication and customer satisfaction at reduced costs. Security enables these technologies to be suitable for these organizations because of the advent of authentication, digital certificates, various encryption methods, hardware, and software and network appliances. Theses technologies, along with others are entering the mainstream of business computing, advancing many corporations into the next generation.

Building a Secure Enterprise Grade VPN The rising popularity of Virtual Private Networks (VPN) has given birth to a new technology architecture from Cisco Systems that takes these same VPN concepts and encompasses the additional voice and video requirements into a technology called Voice and Video Enabled IPSec VPN or V3PN. This V3PN concept is in fact just a combination of Voice over IP (VoIP) technologies, Quality of Service (QoS) technologies, and Security services into one architectural view. The purpose of this paper is to demonstrate a secure, scalable, and redundant V3PN architecture that can be used as a model for implementation in the Enterprise.

IP Security Protocol-based VPNs IP Security Protocol (IPSec) defines a set of protocols and cryptographic algorithms for creating secure IP traffic sessions between IPSec gateways. Enterprises can no longer keep pace with ever changing technology; legacy networks such as ATM and Frame Relay are examples of such technologies that are not able to keep up with the technological advances. Flexibility, scalability, global reach, and security are critical network components that help to define an enterprise's success. IPSec Virtual Private Networks (VPNs) allow enterprises to leverage the speed, ubiquity, and flexibility of the Internet, while gaining security beyond that which is Provided by legacy network technologies. There have been many improvements in the internet including quality of service, network performance and inexpensive technologies such as DSL. But, one of the most important advances has been in security.

HOW-TO Securely Use SNMP on a BGP/MPLS VPN Network Let us consider the case of an IP/MPLS Service Provider offering extra-net connectivity, along with access to services. The Service Provider manages its MPLS network and in some cases the Customer Edge (CE) routers. The network operations are made possible by its Operations and Business Support System (OSS/BSS) devices, hosted behind some of its own CE routers. Some value may be added by on-demand services hosted behind CE routers on managed servers. All these components can be managed using SNMP; we will see how to make the components interact safely.

Nortel Instant Internet 100-S VPN Configuration This paper will discuss the configuration and use of the Nortel Instant Internet 100-S as a VPN client in our network environment. The Instant Internet 100-S has evolved from the BayStack Instant Internet product. Nortel acquired this product line when it purchased Baynetworks in 1998. A general description of the product can be found in a n article in the Network World publication dated 11-01-1999 (URL below).

Securing Remote Users VPN Access to Your Company LAN This paper is intended to be an introduction to the Security issues you face and the solutions you can choose between, when you want to give your remote users access to your Company Network via VPN. This topic is very broad, and has many aspects. This paper only focuses on the security aspects of the remote users pc, not including the security of different VPN-solutions, encryption techniques or other aspects related to the VPN-tunnel itself. It assumes a basic understanding of VPNs, IDS technology and common Industry terms and acronyms.

What is a MPLS VPN anyway? This paper is about a new technology, MPLS VPN, that is being offered by service providers to compete with Frame Relay and ATM networks. When a company wants to connect its geographically different sites they don't have to purchase a Frame Relay circuit, or purchase an ATM circuit, or lease a dedicated telco line. They can now go to their Internet service provider and purchase a MPLS VPN to connect their geographically different sites. This paper will give a basic understanding of how a MPLS VPN works.

Knock Knock... Who's there? Do you know who is accessing your VPN? A virtual private network is several security technologies. These include encryption, authentication, and key management. The idea of the virtual private network is to give users of your data access securely whether they are across town or on the other side of the world. While VPNs secure data by encrypting the data across public networks, potential information security risks are your remote users' networks, PCs, systems, etc. How do we know who is on the other end of the VPN? How can we make sure that the person or device on the other end is who they say they are? The answer is strong authentication.

Comparing BGP/MPLS and IPSec VPNs Network managers have many options for site-to-site connectivity. Traditional leased lines, Frame Relay, and ATM based connectivity solutions are giving way to newer VPN technology. Two types of modern VPNs, BGP/MPLS and IPSec are becoming increasingly attractive to network managers. This paper gives an overview of MPLS and then discusses the mechanisms used to provide VPNs based upon BGP/MPLS and IPSec. The paper assesses the security provided by both solutions and suggests guidelines for network managers to assist in evaluating these two options.
