The hackers aim to search through the range of IPv4 and IPv6 IP addresses, looking for VoIP services to target different forms of attacks. Once a VoIP service is revealed, additional types of attacks can then follow.

FREMONT, CA: At the moment, security is one of the most commonly talked about topics, yet the significance of securing Voice Over Internet Protocol (VoIP) is hard to overstate. Due to the progress of VoIP, it is essential to understand some of the common threats. Each device and service are, in part, accountable for offering a secure VoIP solution, but there are a few different ways to install a secure VoIP solution.

Conventional telephony delivered by means of analog or digital encompasses transmission over some physical medium. Security attacks to traditional telephony like eavesdropping need physical presence with access to the physical lines.

Employing Security Best Practices and Why is It Essential

Toll fraud over traditional telephony has numerous forms; one standard attack is to hairpin telecom traffic. This occurrence is when inbound calls into a voice network were sent back out to a substitute destination. Now that voice networking has combined with computer networking; there is an end of geography. Physical presence is no longer essential to gain access to a voice system. Computer networking is an open network system, as any IP Address can connect with any other IP Address.

IP Protocol (IPv4 RFC 791 and IPv6 RFC 8200) and IP Addresses are vital in both public and private networks used in daily communications for both data and voice. This facet leads to computer networking outbreaks having enormously more access and tools available to conduct malicious attacks on VoIP infrastructures.

The hackers aim to search through the range of IPv4 and IPv6 IP addresses, looking for VoIP services to target different forms of attacks. Once a VoIP service is revealed, additional types of attacks can then follow. Therefore, it is best to recognize the tools and methods employed to discover VoIP Services that can merely detect these methods and not acknowledge the VoIP service back to the hacker. If the hacker does not know there is VoIP service, they will most likely overlook and move on.
