Any device which is connected to the internet is susceptible to be hacked by the hackers. Voice over Internet Protocol (VoIP) is a transmission technology of sending voice communications and multimedia sessions over the internet. Therefore, VoIP telephone systems are also susceptible to attacks by the hackers. Hackers can institute denial-of-service attacks, record conversations, harvest customer data etc.
There are some legal issues, which have to be considered when planning to implement VoIP (Voice over Internet Protocol). Incorporating or switching to VoIP technology for your organization’s voice communications, can raise technological as well as legal issues. Voice over IP technology has also enlarged security concerns because VoIP technologies have made it more complicated for the government to decide where a target is actually located when communications are being interrupted, and that creates a lot of new legal issues.

A firewall is a computer program which is intended to block unauthorized access to the computers or networks. A firewall was developed in response to a number of major internet security breaches, when the first internet virus Morris Worm was detected in the late 1980s. Although Morris Worm was not malicious, it originated multiple vulnerabilities in the computers (machines).
