OpenScape - VOICE/UC / Unified communications Video
« on: January 31, 2009, 11:44:17 pm »
With desktops, laptops, PDAs and mobile phones, our communication systems have become fragmented. David Leach, senior public consultant for Siemens Enterprise Networks, explains how unified communications integrates these existing tools and devices into a single platform.

Mit einer aufgebohrten Laptop-Karte für 23 Euro lassen sich laut Sicherheitsexperten Telefonate auf Basis des weit verbreiteten Standards Digital Enhanced Cordless Telecommunication einfach abhören.
Wer vertrauliche Telefongespräche führen will, sollte besser nicht zu einem der gängigen schnurlosen Fernsprecher auf Basis des DECT-Standards (Digital Enhanced Cordless Telecommunication) greifen. Wie Sicherheitsexperten auf dem 25. Chaos Communication Congress (25C3) in Berlin ausführten, lassen sich derartige Kommunikationen leicht abhören. Erforderlich ist demnach allein eine aufgebohrte, eigentlich für die Internet-Telefonie gedachte Laptop-Karte für 23 Euro und ein Linux-Rechner. Keine Probleme mit dem Abfangen von DECT-Ferngesprächen habe diese Vorrichtung, wenn ­ wie sehr häufig ­ eine Verschlüsselung überhaupt nicht aktiviert werde. Aber auch bei einem anfangs verschlüsselten Informationsaustausch könne die Steckkarte eine Basisstation vortäuschen und die Kryptierung dabei deaktivieren.

Das vom European Telecommunications Standards Institute (ETSI) genormte DECT-Verfahren wird weltweit am häufigsten genutzt für schnurloses Telefonieren. Darüber hinaus kommt der Standard auch in Babyfonen, Notrufen- und Türöffnungssystemen, schnurlosen EC-Kartenleser oder gar in Verkehrsleitsystemen zum Einsatz. Die Zahl der aktiven DECT-Endgeräte wird allein hierzulande auf 30 Millionen geschätzt. Für die Authentisierung der Basis und der zugehörigen Endgeräte sowie für die mögliche Verschlüsselung der Datenübertragung nutzt DECT standardisierte Kryptoverfahren.

Die eingesetzten Algorithmen sind dabei in den Geräten fest verdrahtet und werden allesamt gegenüber der Öffentlichkeit geheim gehalten. Das Stammnetzwerk verlassen verwendete Schlüssel nicht. In der Theorie sehe das alles recht solide aus, erklärte Erik Tews, einer der an der Entdeckung beteiligten Forscher von der TU Darmstadt. Die Praxis weise aber diverse Umgehungsmöglichkeiten und Angriffsflächen auf.

Nachdem die Hacker zunächst einen recht teuren und hohe Prozessorleistungen voraussetzenden DECT-Sniffer gebaut hatten, fanden sie laut Mitstreiter Andreas Schuler mit der ComOnAir-Karte eine "andere schöne Hardware" zum Empfang des Datenverkehrs. Nach einem Reverse Engineering, dem Nachbau des Schaltplans, dem Auffinden der Fimware und dem Anlöten einiger zusätzlicher Leitungen sei nach einem knappen Monat der gesuchte, etwa aus einem vor einem Haus geparkten Auto einsetzbare Sniffer fertig gewesen.

Den Tüftlern sei damit rasch aufgefallen, führte Tews weiter aus, dass manchmal überhaupt kein Authentisierungs- oder Verschlüsselungsprozess zwischen der Sendestation und dem Handgerät aktiviert werde. Vielfach authentisiere sich das Telefon nur gegenüber dem Netzwerk wie beim Mobilfunkstandard GSM, auch wenn sich bei DECT prinzipiell zudem das Netzwerk gegenüber der Empfangseinheit gleichsam ausweisen könne. Bei anderen Geräten erfolge zwar eine Authentisierung, allerdings ohne Verschlüsselung. In all diesen Fällen habe die PCMCIA-Karte mit einem speziellen Linux-Treiber aktive Gespräche aufspüren, die Daten extrahieren, auf ein Speichermedium schreiben und einem Audio-Player zuleiten können. Es sei möglich gewesen, jede Konversation in einem derart schlecht abgesicherten DECT-Netzwerk aufzuzeichnen.

Falls das Handset Gespräche verschlüsselt habe, sei der Fall auch nicht viel schwieriger gewesen, betonte Tews. Mithilfe eines modifizierten Treibers und eines Skripts habe man den Sniffer als Basisstation ausgeben sowie den Datenverkehr dank der VoIP-Unterstützung auf einen Asterisk-Server umleiten und ebenfalls aufnehmen können. Ein Brechen von Schlüsseln sei nicht nötig gewesen, da beim Aussenden eines Signals, dass Verschlüsselung nicht unterstützt werde, auf Kommunikation im Klartext umgestellt worden sei. "Das funktioniert bei allen Systemen, die wir hierzulande gefunden haben", unterstrich der Darmstädter Wissenschaftler die Anfälligkeit üblicher DECT-Implementierungen.

Auch beim Verschlüsselungssystem selbst fanden die Hacker erste Knackpunkte. Laut Tews gelang es ihnen, ein Reverse Engineering des zentralen DECT Standard Authentication Algorithm (DSAA) beziehungsweise seiner vier Unterausführungen durchzuführen. Ein Forschungsbericht dazu ist auf der Projektseite dedected.org zu finden, Implementierungen und Quellcode für die Programmiersprachen C und Java sollen bald folgen. Ganz gebrochen ist der DSAA bislang aber noch nicht.

Auf den ebenfalls geheim gehaltenen DECT Standard Cipher (DSC) gibt es gemäß Ralf-Philipp Weinmann aus dem Forschungsteam ebenfalls noch keinen wirksamen Angriff. Ein Patent, das Alcatel in Spanien und in den USA beantragt habe, sei aber hilfreich gewesen beim Aufspüren möglicher Schwachstellen des Codes. Als wenig robust hätten sich ferner die Generatoren für die zur Verschlüsselung benötigten Zufallszahlen erwiesen, sodass man auch darüber Handsets simulieren und verschlüsselte Gespräche entschlüsseln könne. Nicht zuletzt kündigte Weinmann an, dass der WLAN-Sniffer Kismet in seiner nächsten Version ebenfalls DECT unterstützen werde.

[update]
Der Umweg über die Com-On-Air Karte wird sich dadurch allerdings nicht erübrigen. Auch die Software Kismet, die jetzt zum Scannen von DECT-Netzen benutzt werden kann, benötigt die Com-On-Air Karte. DECT und WLAN funken in unterschiedlichen Frequenzbereichen, so ist es mit üblicher WLAN-Hardware nicht möglich, sie zum DECT-Scannen zu mißbrauchen.

The new multi-tenancy licensing option in its OpenScape Contact Center solution opens up new markets for the company, says one analyst.

With ever-increasing customer demands for improved service and mandates from the boardroom to keep down costs and streamline processes, large enterprises with multiple business units and separate contact centers are feeling the pinch. Looking to alleviate these concerns, Boca Raton, Fl.-based enterprise solutions provider Siemens Communications unleashed its latest version of OpenScape Contact Center (OSCC), available with multi-tenancy licensing.

Ross Sedgewick, director of global marketing for large enterprises at Siemens Communications, explains that many of his company's larger customers would have to set up individual contact centers for each of its business units, even with a private branch exchange (PBX) switch and separate server for each of their discrete operations. Click here to learn more! Click here to learn more!

He gives three different typical scenarios for these siloed implementations. First, particularly in the financial services industry, it was a regulatory necessity to maintain separate databases and administrative access. Second, compliances including the Health Insurance Portability and Accountability Act in the healthcare space require specific privacy provisions and regulations. Sedgewick concludes by explaining that there are multiple business entities-including customer service, direct marketing response, and internal information technology help desks-that have a need to maintain separate databases, reporting, routing, administration, and security.

While necessary, it was a pain point for many organizations. "Our customers would have to go through separate installations of a contact center solution which was more complex to manage and expensive to own over time," Sedgewick recalls. "Now we can deploy once in one centralized data center ... and be able to service multiple business unit entities from one installation."

Joe Outlaw, a principal analyst in the contact center space for San Antonio, Tex.-based research firm Frost & Sullivan, explains that while multi-tenancy licensing is not a new innovation, it is an important one for the company to drive home its value proposition. "This allows you to partition off the contact center application in a way that there's no compromise to data and the people can have what looks to be their own system in the midst of a [centralized] one," he says. "That's a way to have economies of scale that the service providers often find important."

Other features in the latest version of OSCC include:

    * bolstered scalability with up to 1,500 active agents supported by a single server;
    * support for multiple time zones;
    * a manager desktop providing business-level permissions and system access; and
    * enhanced security, including a new permissions hierarchy aimed at a more secure way to grant this to administrators without also giving access to routing, reporting, and monitoring views of other business entities.

Sedgewick stresses this release opens up a new market for the company-namely outsourcers and service providers. "This type of solution is excellent for them to partition and manage one common system and scale up to manage multiple client operations on one solution," he says.

Outlaw echoes Sedgewick's sentiments, explaining that it shows a shift in strategy. "Siemens' contact center business historically targeted midsized to some large companies, not service providers," he says. "Also, ease of use hasn't been a priority in the past, but the company sees it as important as it enters the enterprise market. If you look at OpenScape, a lot of effort was taken to redesign the application to make it easy to use ... and that carries through."

Gartner Positions Enterasys and Siemens Enterprise Communications in Wireless LAN Magic Quadrant.

Enterasys and Siemens Enterprise Communications announced the company was positioned in the visionaries quadrant in the Gartner Magic Quadrant for Wireless LAN Infrastructure 2008 report (Gartner ID Number G00163188).

According to the report, "A vendor in the Visionaries quadrant demonstrates an ability to increase features in its offering to provide a unique and differentiated approach to the market. A visionary will have innovated in one or more of the key areas of WLAN technologies (convergence, security, management or operational efficiency)."

"Differences in WLAN architecture, enhanced security and management features separate the offerings from each vendor," the report said. Moreover, "Although WLAN vendors continue to innovate more rapidly on the technology front, the traditional wired infrastructure vendors are marketing increasingly compelling arguments for combined application services such as management of wired and wireless networks."

Published 26 November 2008, the Gartner report said, "While all vendors continue to support basic end-user connectivity, additional requirements for security, management, voice capabilities, and integration with management or security appliances continue to drive vendor selections."

"We are pleased by our positioning in Gartner's Magic Quadrant and believe that this is confirmation that our convergence, security, management and operational efficiency are fundamental strengths," said Chris Crowell, Enterasys EVP Operations and CTO. "Capital savings can result from competing the combined wired and wireless business between multiple vendors in a challenging economic environment. Our integrated switching, management software, and security across wired and wireless networks enable IT to complete their projects on-time within the constraints of a reduced budget."

Enterasys this week is expected to announce integration of the Siemens Enterprise Communications WLAN portfolio with its switches and management systems.
Enterasys is now offering Siemens Enterprise Communications' HiPath 802.11n products. Enterasys is also unveiling a wireless controller network expansion module, which integrates wireless switching into the Enterasys Matrix N-Series LAN switches.

The new C20N wireless controller is a daughtercard within the switch so it does not occupy a chassis slot, Enterasys says. The C20N is an addition to the current C20, C2400C and C2400E controllers Enterasys already offers for office, campus and enterprise deployments. Enterasys says users can now configure and power dual-band 3x3 MIMO 802.11n HiPath access points via a standard IEEE 802.3af PoE port found on many deployed LAN switches. Integration between Enterasys' NetSight software and the HiPath products provides visibility of HiPath access points, controllers and wireless clients from a NetSight console, Enterasys says.

Enterasys says it also now provides integrated wired and wireless security management by now including Siemens' HiGuard software, which provides embedded wireless intrusion prevention and location-based services; and by unifying NAC identity-based policy privileges across the wired and wireless infrastructure to deliver role-based access control. The C20N wireless controller can support of up to 64 access points per blade – or 7,000+ users per chassis -- in a high-availability deployment, or 32 access points per blade in a standard configuration, Enterasys says.HiPath Wireless Manager is integration component for Enterasys NetSight included as part of the annual maintenance agreement.

Press Briefing which introduces OCC Product.

Siemens Enterprise Communications introduced the OpenScape Contact Center, a comprehensive voice, unified communications and customer interaction software solution designed to work with virtually any existing telephony environment. It is based on Siemens’ innovative new unified communications software foundation, OpenScape Unified Communications (UC) Server, which removes the artificial legacy barriers between today’s traditionally separate voice, video and unified communications systems to enable a comprehensive suite of UC applications.

The OpenScape Contact Center offering builds on the presence-enabled HiPath ProCenter Enterprise contact center application to provide a platform to enhance customer interactions across multiple segments of an enterprise, on virtually any existing communication or network infrastructure. Coupled with the OpenScape Voice Application, this robust solution supports environments of up to 7,500 active agents and includes optional voice and contact center server redundancy with automated fail-over to help ensure availability of mission critical customer interaction systems.

Leveraging the OpenScape UC Server foundation, it can provide agents with an aggregated, unified desktop client view of all contact center personnel and enterprise users’ presence and availability. This enables agents to specifically address urgent, complex, or sensitive customer interactions requiring escalation beyond the contact center and drives up first contact resolution by tapping the knowledge and expertise across the enterprise in real-time.

The OpenScape Contact Center also addresses the traditional limitations of the hardware intensive site-based contact center by migrating to SIP and providing the new OpenScape UC Application, Personal Edition, soft phone and productivity desktop for each agent. This SIP-based contact center virtualization capability makes every agent a UC user, while enabling agents to work in any location equipped with just headsets and minimally configured desktops. This easy, software-based expansion of ‘on-demand’ agents offers enterprises dramatic opportunities to leverage their distributed resources across multiple sites, branch offices, remote or home-based locations with secure IP network access.

Also announced today, the new IP-based Voice Portal application complements the OpenScape UC Server and adds to Siemens’ already robust offering by delivering a comprehensive, natural speech enabled self-service solution. The open standards-based Voice Portal solution can help enhance the experience of customers calling in to a contact center by providing enhanced self-service options as well as seamless integration with the contact center routing engine and virtual agents. It can help improve the opportunity to resolve issues on the first call while optimizing the use of agents and technology.

“The OpenScape Contact Center solution is further evidence of Siemens’ ongoing transformation into a software-oriented company and is an important piece of the OpenScape UC Server platform,” said Al Baker, Vice President Global CRM/CI Solutions, Siemens Enterpise Communications. “This solution rounds out Siemens’ suite of UC applications by delivering a comprehensive, robust offering that demonstrates the value of Open Communications in customer interactions.”

Computacenter, an IT service & solution provider that recently migrated its contact centre service to the OpenScape Contact Center, saw the new solution as a means to help achieve their stated goals as a multi-national service provider. “We saw this as a way to increase our scalability, flexibility and resiliency. We are vitalizing operations across multiple European and offshore locations using a highly scalable and more cost effective software deployment model. We are looking to expand our presence and collaboration capabilities into the virtualized enterprise,” said Gavin McLachlan, UK IS director at Computacenter.

The OpenScape Contact Center packaged offering, which includes the OpenScape UC Server, OpenScape Voice, HiPath ProCenter Enterprise, and OpenScape UC Application, Personal Editions, will be generally available June 30, 2008. The package starts at €31,500 for 100 voice users, 10 agents and 1 manager. The new Voice Portal solution is currently available, with pricing based on customer configuration starting at €23,070 based a 48-port configuration.
