Securing Virtual Unified Communications Solutions

Siemens Enterprise Communications Chooses Trend Micro Deep Security™

Siemens Enterprise Communications can look back on a long history of excellence in voice and data communications – no less than 160 years. Today, the company is one of the world’s leading providers of unified communications (UC) infrastructures. It has over 10,000 staff in 90 countries providing customers with enterprise communication solutions and services. Companies can choose between an implementation of the system at their premises; a managed service delivered by Siemens Enterprise Communications; or the new cloud-based option. Trend Micro’s Deep Security ensures the security of the UC environments that are virtualized using VMware.

Software-based voice, UC and contact center solutions, along with Enterasys Networks’ solutions for network infrastructure and security, form the company’s technological cornerstone. Its customers have the flexibility to choose how to migrate to IP-based unified communications as well as how to deploy it. At Siemens Enterprise Communications, the focus is on helping companies of any size to implement unified communications. The UC and collaboration package uses the OpenScape UC Server platform which can be integrated into an existing network and includes multiple applications. Customers can choose to run these within their own infrastructure, entrust them to Siemens’ Managed Services division, or opt for Siemens Enterprise Communications’ new cloud-based security service.

“In virtualized environments – such as our voice over IP solutions – it’s of crucial importance to use tailored UC security solutions to protect virtual borders,” emphasizes Frank Semmler, Head of Solution Management Security at Siemens Enterprise Communications. These UC security solutions include firewalls, session border controllers, NAC, user provisioning, access management and single sign-on along with virus and malware protection. As a service provider, Siemens Enterprise Communications deals with a very wide range of security requirements, depending on the size of the company as well as on the type of service needed. An antivirus and anti-malware solution is included as standard for all UC applications.

Up until recently, Siemens Enterprise Communications implemented virus and malware protection on the UC application servers that was personalized for each customer – often using different solutions from different vendors. There were two main disadvantages to this approach. The first was technical, in the sense that the company had to work with multiple different management consoles and ensure that the relevant technical expertise was available in-house. The second disadvantage was financial, with the high cost of supporting multiple solutions.

Why Trend Micro

“Our goal for the implementation of UC solutions was to provide a high standard of security at a reasonable cost, but we clearly weren’t going to achieve that with the approach we had,” explains Frank Semmler. As a result, Siemens set about finding a standardized solution that was repeatable yet adaptable to each customer’s needs, available globally, and easy and cost-effective to implement. The security software also needed to be able to support a wide range of applications for different operating systems and be optimized for these applications running in VMware-based virtual environments as well as in both private and public clouds.

“We soon realised that the only solution available that fulfilled all our requirements was Deep Security from Trend Micro,” says Frank Semmler. Deep Security provides advanced protection for servers in dynamic data centers, whether physical, virtual or web-based. It combines detection and blockage of intrusion attempts with firewall, integrity monitoring and protocol checking functions in a centrally-managed software agent. The solution enables companies to detect suspicious activities and take preventive measures, ensuring the security of the data center.

“Another reason why Deep Security is ideal for our unified communications solutions is that it is the only one to protect virtualized environments with no need to make changes to the systems needing protection,” comments Frank Semmler. Trend Micro’s security software works without installing agents on the target systems. The advantage of this agentless approach is that it facilitates implementation – not only in the applications themselves, but also in time-critical hardware components in telephone systems. Changes made in this area can sometimes result in voice quality being compromised and even in malfunctions. This is where the agentless Deep Security solution can really shine, because it protects these components without affecting the way they work.

In January this year, the two companies started implementing the Deep Security virus and malware solution in Siemens Enterprise Communications’ own OpenScape Cloud Solutions. The goal of the implementation projects is to ensure protection against viruses and malware for all server-based UC applications and management servers on both Windows and Linux systems. The first project was completed in June this year, enabling Siemens Enterprise Communications to provide UC in the form of a public cloud service. The antivirus and anti- malware software from the Deep Security solution is an integral part of the new service’s security infrastructure.



“Now that we’ve standardized the security offering for the Siemens Enterprise Communications UC solutions, customers benefit from a higher level of security at significantly less cost compared to the individual virus protection we used to provide,” explains Frank Semmler. But customers are not the only ones to benefit. The solution gives Siemens Enterprise Communications itself a competitive advantage - with fast, reliable solutions built on deep expertise as well as with a competitive cost structure.

“Deep Security will provide us with further business opportunities, because its modular architecture enables us to gradually implement additional security functions in virtualized environments that go beyond the virus protection functions provided as standard,” notes Frank Semmler. He says the company plans to extend its collaboration with Trend Micro and is currently looking at leveraging Deep Security’s support for multi-tenancy – an important consideration for cloud-based solutions. The company is also planning to implement other Deep Security functions in its own products in a phased approach, notably virtual IPS and the virtual firewall.
