Yesterday we discussed security features within cloud hosted VoIP such as firewalls, passwords and WiFi. Now, let’s delve into a few more important security features to consider when weighing your options of cloud hosted VoIP as a telephone service option.
DDoS
One of the worst security threats is a DDoS (or a Distributed Denial of Service). A DDoS usually comes with infected Trojans and are used to target sole systems. In terms of VoIP, a DDoS usually manifests a ‘busy signal’ on your IP business phone system. VoIP relies on continuous and reliable packet flows. When your company becomes the victim of a DDoS, availability becomes a real problem.
Fortunately, there are a few options that will help: SIP and H.323. If you have VoIP, these two protocols are great tools for guaranteeing your sensitive data will not be comprised when it is transmitted over the Internet.
Phantom Calls
How would you feel if you got a call on your IP phone from a mysterious extension and you only heard silence when you picked up? Annoyed, right? These are called phantom calls, and alas, they can be more than just annoying if you don’t have the proper firewall set up. A true phantom call is made by a “port scan” by hackers fishing for a vulnerable phone network in which to gain access to. As long as your firewall and firmware is kept up to date though, you should be safe.
Is VoIP service secure?
VoIP certainly comes with its risks, but at the end of the day, if you remain vigilant in your security procedures the risk can be minimal. Proper planning and effective security procedures ensure that IP telephony is both convenient and safe.
