When we talking about secure communication we consider communication that cannot intercept by a third party, two people can share their information without any third person involvement. In IP Communication security is a big issue naturally this is unsecured communication that can be protected by using some security tools. Securing or protecting communication is not a very easy task as like just on a firewall it is a multiple-step process that needs proper tools protecting from unwanted eyes.

Communication security threats are not new in IP Communication. we have familiar with them and known as Phone Phreakers. In the 1960s mechanism of communication-based on ISDN lines, these Phone Phreakers make a fool to phone companies and illegally facilitate people to do phone calls at cheap rates within the country and across the borders. But in IP Communication these Phone Phreakers are more powerful as before their target area is not a specific country they can target in any country where he found weak security measurements.

As we know that it is a challenging task to properly secure IP Communication. Let's see some common issue which becomes the cause of attacks.

Most companies and enterprises cannot use encryption in IP-based Communication for the reason of high performance and quality communication. These types of companies become easily the victims of hackers. Many tools are available on the internet that easily unencrypted these calls and hackers easily listen to their personal information.

Some hackers access your personal and sensitive data fraudulently by sending an email or text messages with some pitch like that Congratulation you have been winning the lottery for getting this prize money to send us your personal information such as bank account info, Name, DOB, etc. Through this way, they get your personal information and using this information for illegal activities.

Most of the companies and enterprises have a common practice they separated their voice traffic from other traffic. For separating this traffic they commonly use virtual networking. Hackers use virtual networks as a way to enter into the main system because hacking virtual network is easy a lot of tools freely available on the internet for hacking virtual networks.

We should consider these threats when we implement IP Communication in our companies, organization, or institutions. We should take security measurements to overcomes these threats.
