Practical VoIP Security

VoIP Security is one of the most important issue because we use this technology to communicate, in other words we actually exchange information through VoIP. If we are dealing any business through VoIP and somehow due to some sort of security holes someone accesses it then that could be disaster to any business man and that information could be miss use in different ways.

I mention business because VoIP is cost cutting solution and many companies are replacing regular telephone because of cheap VoIP services. But let’s take another example. Guess you are using VoIP for just personal purpose to communicate with your friends, families and love ones. But still you should concern about VoIP security issues because recently there are countless websites and companies formed just to get your personal and sell it.

Your call can be tracked and recorded due to many reasons some for example: may be any government issues or if you are experiencing time or someone is spying on you. When you join anyyou will find long page of privacy and security policy but such pages won’t help you all the time.

Assume that you are calling to conventional telephone line through VoIP but in such situation you have two types of security threads both in analog signals as well as in digital signals because when you call to conventional line through VoIP than your data will transfer through many complicated path reaching from routers to multiple servers and at last to your conventional line reaching through analog signals.

Because your data travels through different routes and paths it becomes possible to crack it, if tech savvy pissed on you then it can give a hard time.


Beside all the issue about VoIP security there is one way out. VoIP security best practice is to encrypt your calls. Encryption is very useful method which changes the entire data in to a form that actual data cannot be extracted unless you’re got accesses to thesecurity key. Encryption has different levels like 128 bit, 256 bit and so on. 256 bit is widely used middle level encryption which cannot be broken easily unless the government starts giving full concentration in your data, but still it takes time and most of the time it’s impossible because most of the country don’t’ have such technology. Hence, you can consider 256 bit encryption a secure practice.

Actually, there is one VoIP Service Provider which use 256 bit AES (Advance Encryption Standard) and that is Skype. But the other provides like Google Voice and Yahoo won’t practices suchsecurity.

Well no one can deny the power of 256 bit encryption but most of the time encryption is not a sole method to stay safe because if your PC is infected or malfunctioned than there is not much to help. You might hear about programs which installed automatically in your systems and send your confidential video audio as well as keyboard activities to its source. For example: if that software is recording your keyboard activity and you entire your username, password, your name, address, credit card numbers etc. all these information are send from your computer to the source through internet.

If you want to secure your information than make sure that your software stays update and if your computer has good system configuration then let antivirus run in background all the time or else scan your computer once in every week. Make sure that you antivirus are full version with complete internet protection suite. Hence, this following this you can at least 60% safe.

There is nothing which can make your VoIP calls 100% secure but following the mentioned procedure will definitely help you.
