Managing VoIP Security and Bandwidth

Updated on December 27, 2011

Emerging VoIP Security

It's one of the laws of computing that any new field insufficiently advanced attract its share of security vulnerabilities. White is no exception to stop in the early days, there simply wasn't enough volume to make it an attractive target to stop hackers and other malicious elements had better ways to invest their time and effort. But now, the story is very different. White has proliferated enough to make hackers sit up and take notice. With this increased attention, come new ways of exploiting the VoIP infrastructure. Attacks can range from using VoIP vulnerabilities in order to gain access to the larger network, or breaking in in order to get access to unlimited free international calling. Either way, it can prove disastrous for a company.

There are many approaches to dealing with this problem. Depending on the particular VoIP model in use, the burden of taking care of the security can be passed on to either the company itself, or the ITSP who provides the service. Regardless, there are certain security measures that must be taken no matter who bears the brunt of responsibility. One such example is the use of virtual LANs or VLANs which segregates VoIP traffic into a separate virtual network to which special security rules can be applied and which can be isolated from the rest of the corporate infrastructure.

Concentrating Security Efforts

If you're hosting your own VoIP system, you not only have to take care of configuring it correctly, maintaining the hardware, and hiring employees with technical know-how to take care of it, you also have to bear the burden of "hardening" it from attacks which originatefrom both inside and outside. Such expertise is not easily available since VoIP is a relatively new field. And it can prove too expensive to learn by experience alone. Large corporate houses can circumvent this problem by hiring specialists of their own. But small and medium-sized businesses cannot afford this luxury.

This is one of the special benefits of a hosted PBX system. The ITSP will help you in configuring an SIP account in such a way as to defy intrusion attempts. Keep in mind that those who are managing your VoIP system for you are professionals – it's their job. They will keep up with the latest technological advances and the best security practices in order to keep their customers safe. The SIP VoIP proxy server will be a single point of contact between your organization and the VoIP network, thereby acting as a kind of firewall all by itself. This concentrates the security efforts at a single point and eases the management.

Contact your ITSP today and find out how you can obtain quality mobile VoIP services in as little as 15 min. once you see the benefits which VoIP brings your organization, there's simply no going back.
