VoIP Security Dangers to Watch Out For

A modern security firewall scans data to ensure it is safe, but an older model makes the process much longer than it needs to be.

FREMONT, CA: Today, Voice Over Internet Protocol (VoIP) technology provides a new way for hackers to listen to it, which is why companies need to use the best security protocols for their communications networks. There are usually obvious signs of a VoIP breach, but what flaws might one be looking for in their centralized communications or business VoIP calling systems?

Security Risks

1. Internet Bound Traffic

The VoIP phone system uses internet telephony to provide information. The VoIP traffic that passes through these lines is automatically less secure, and packet loss is easily triggered by packet sniffers that aim to steal information. To help make the internet lines more stable, use a reliable VPN SMB alternative or a virtual private network to transfer files. It takes some time to set up and operate, but it guarantees that the information is secure.

2. VoIP Network Firewalls

Software and hardware firewalls are configured to secure the device, but when it comes to VoIP, firewalls are limited. Old firewalls will not accept VoIP facilities so that the firewall will block VoIP protocols from the system incorrectly. A modern security firewall scans data to ensure it is safe, but an older model makes the process much longer than it needs to be. Get a firewall that deals with VoIP phones, and run performance checks to ensure the IPs run a firewall without having performance problems. An up-to-date firewall scans information without triggering packet loss or slows down.

3. SPIT

SPIT, which is Spam Over IP Telephony, is close to the spam one receives in their emails. SPIT is pre-recorded messages sent to VoIP phone networks. These calls are typically an annoyance that connects one's virtual phone numbers, but spam brings other threats, such as viruses, ransomware, and other harmful attacks on a company. A reliable VoIP approach helps to ensure the spam is not detrimental to the phone device. There is no way to avoid SPIT entirely, so using a firewall helps detect the spam as it comes and monitors it not to overload the system.
