The Changing Role of Session Border Controllers

Audio : Download file (TS-375368.mp3)

Guests: Steven Johnson, President and Product Support Director Scott Beer of Ingate Systems AB, a Stockholm, Sweden based high-tech company that designs, develops, manufactures and markets data communications products for trusted Unified Communications. Ingate designed the world’s first Session Initiation Protocol (SIP)-capable firewalls and SIParators, products that enable Unified Communications over the Internet.

The Ingate SIParator® is a device that connects to an existing firewall to seamlessly allow the traversal of SIP-based communications. Ingate SIParators are compatible with all existing firewalls and operating systems.

The Changing Role of Session Border Controllers:  Ingate’s SIP-capable E-SBCs protect and enable SIP networks worldwide.  E-SBCs used to just serve a primary role of security.

We will be discussing the following pooints:

- Talk about the security role E-SBCs play.  One question many people ask us is, “Why have an E-SBC in a SIP trunk deployment if the service provider is taking on security?”  There is an excellent answer to this, one that every end-user needs to know.

- Address common security mistakes we see in SIP implementations.

- Discuss how E-SBCs enable SIP trunking and other SIP-based applications, like video, citing case studies

- Talk about Unified Communications.

Tim will try to describe (with help from OpenBTS’s David Burgess) the technical, regulatory and logistical challenges that we faced before we could make the first call.

Beginning OpenVPN 2.0.9

OpenVPN_2.0.9
The VPN topic will be of interest to all on the VUC so we’re inviting Markus Feilner, author of “Beginning OpenVPN 2.0.9“.

Two copies of this book to give away today

The following is from the preface of the book, co-authored by Norbert Graf:
OpenVPN is an outstanding piece of software that was invented by James Yonan in the year 2001 and has steadily been improved since then. No other VPN solution offers a comparable mixture of enterprise-level security, usability, and feature richness. We have been working with OpenVPN for many years now, and it has always proven to be the best solution. This book is intended to introduce OpenVPN software to network specialists and VPN newbies alike. OpenVPN works where most other solutions fail and exists on almost any platform. Thus, it is an ideal solution for problematic setups and an easy approach for the inexperienced.
On the other hand, the complexity of classic VPN solutions, especially IPsec, gives the impression that VPN technology in general is difficult and a topic only for very experienced (network and security) specialists. OpenVPN proves that this can be different, and this book aims to document that.
I want to provide both a concise description of OpenVPN’s features and an easy-to-understand introduction for the inexperienced. Though there may be many other possible ways to success in the scenarios described, the ones presented have been tested in many setups and have been selected for simplicity reasons.
