VoIP has come a long way from its humble beginnings and established itself as a trusted component of mainstream communication. An ever-increasing number of individuals and businesses rely on this technology for its simplicity, versatility, flexibility, and affordability. However, as the technology evolves, so do the questions surrounding the risks of VoIP.VoIP goes through online networks rather than individual, physical phone lines. This means access to one employee’s credentials can threaten your entire work environment. A hacker can quickly install malware on devices that aren’t protected, and instantly access phone conversations and other customer data through the employee’s computer.
Risks of VoIPThe ability to connect has not only skyrocketed our productivity but also subjected us to increased vulnerabilities. Everyone from small businesses to large have shown that everyone is susceptible to attacks on their infrastructure. Examples of multi-billion dollar companies like Yahoo, Target, and JP Morgan Chase. While security breaches can happen to anyone, knowing how to handle them is key to having a successful modern business. As with all security risks, there are ways to minimize the impact and protect yourself from attack. We will tackle some of the biggest security issues involved in using VoIP technology. Also, finding out how to protect your business from attack.
Denial of Service (DOS)What it is: Denial of Service is one of the most common concerns for all business networks. The end goal of any DoS attack is to overwhelm a system with so many requests that it is eventually forced to shut down. This is most often seen on media streaming sites. An overwhelming demand can cause the system to slow down or stop entirely. Similarly, In a VoIP system, hackers use an automatic phone dialer that keeps rapidly calling and hanging up. This keeps your line too busy to accept other calls, essentially clogging your business phone lines. How to Prevent it: There are many new security protocols available that can help protect your communication infrastructure against attackers. One example is using Session Border Controllers (SBC)that act as a kind of VoIP firewall. SBC’s are able to protect your network by building a secure connection between you and your service provider while giving you more control over the VoIP calls and voice traffic your business handles.
EavesdroppingWhat it is: Eavesdropping is a classic technique made modern. Often used for identity theft, eavesdropping on VoIP calls usually involves tapping into an unencrypted call while it’s being transmitted over your internet or data network. Without encryption, cybercriminals can more easily intercept sensitive customer information such as names, birthdates, banking information, and passwords. How to Prevent it: These days it’s easier than ever to set up data and voice encryption on your VoIP systems. Here are a few simple ways:
- Transport Layer Security (TLS): This secures incoming and outgoing traffic between callers to prevent eavesdropping.
- Secure Real-Time Transport Protocol (SRTP): This encrypts data packets transmitted during calls so that eavesdroppers cannot decipher them.
- Virtual Private Networks (VPNs): VPN’s provide a secure, encrypted tunnel that allows you to transmit and receive data safely.
