VoIP Security Primer

Information security is a top priority for any business and VoIP technology aims to meet and exceed security needs. With an increasing amount of business communications, payments, and even offerings going online, it’s important to understand digital security.

Data and information security with VoIP rely on a combination of software and physical features. That said, the most important part of a security policy remains educating employees on how to handle interactions and to spot intrusions.

Take a look at this breakdown of the security features provided throughs VoIP service. 

Business Needs and VoIP Security 

Customers trust a business to keep their information from being leaked. Businesses walk the line between their responsibility to protect customer information and a desire to keep themselves profitable.

To mitigate the risks of data security, VoIP starts by providing protection through the very infrastructure that brings it into the office. This includes aspects of encryption and packet conversion that thwart signal interception from revealing actual information. 

Encryption requires a key to unravel the coded information. Even with the power of current computers, brute force cracking encryption is practically impossible. 

Packet conversion involves disassembling and reassembling of information according to precepts sent in the signal. This means that the signal needs to be sent and received in totality to be understood. Missing parts leave the information within inaccessible gibberish.

Additionally, VoIP uses identity management to send precursor signals that confirm the recipient identity. Precursor signals help the signal to travel without interruption. 

This is an example of how the foundation technology that powers VoIP to deliver clear calls also results in security. 

Security Components

VoIP doesn’t rely on one technology to secure a call but multiple, interconnected components. By layering defenses, VoIP provides more security to a transmission than any individual piece could alone.

These components are: 

  • IP Challenging
  • ISP Security
  • Network Points

IP challenging sends a request to confirm that a signal originates from the area it claims to. With mobile numbers being transportable these days, it gets harder to know if a call from an area code actual originates from that area. IP challenging susses out when signals are being bounced through IPs to disguise origins. 

IP challenging helps prevent anonymous calls from coming into the network. This also identifies when multiple attempts are made at a system from the same source. 

Network points work to keep information sent through VoIP out of the general feed of digital traffic. Mobile phones bounce signals to multiple towers to enhance connectivity. VoIP directly connects one point to another. 

This process, known as tunneling, shortens the path that a signal has to travel which keeps it secure by providing fewer chances of interception.

Finally, ISP security works independently of VoIP security. If a company is working with a quality ISP, they have additional security under that umbrella. 

A poor ISP creates vulnerabilities of access but not always of information. The layered protections continue to impede data access from becoming data loss. 

It is always recommended to review network accessibility and routinely change passwords at access points. The largest vulnerability to any system remains the people using it.  

Get Started

VoIP systems are always upgrading to meet the threats of the online world. 

VoIP provides more security than a landline. Even when a breech occurs, the technology enables a business to trace the source and to know when it occurred. Contact Vegas Telecom for additional information about how VoIP meets your security needs.
