VoIP systems offer several advantages over traditional phone systems, such as mobility, expandability and low maintenance costs. There are, however, some concerns about the security of cloud-based phone systems and how they’re perceived to be less secure than their analog counterparts. In this blog, business phone systems provider One Call shares an in-depth look at VoIP phone security.
Analog vs. DigitalIt’s important to note that both traditional phones and cloud-based phone systems have inherent vulnerabilities. Authorities, under certain circumstances, have the equipment to listen in on phone calls when needed. The same is also possible for digital systems, and with the level of virtualization afforded by cloud-based telephony, it’s possible for unscrupulous individuals to intercept data packets at certain points. In comparison, wiretapping analog phones is much more difficult, as it requires physical connections to accomplish.
Simply put, security risks are present in both systems. It’s important to note that these risks can be mitigated, avoided or even eliminated. There are laws against wiretapping that prevent people from casually using certain devices for this purpose. Regular security inspections can help detect the presence of such devices in traditional business communication systems.
Reducing VoIP Security RisksTaking the same preventive approach can also help minimize security risks to VoIP telephone systems. Here are some of the most common ones:
Denial of Service — A Denial of Service attack sends multiple requests to a system until it’s overwhelmed and forced to shut down. On a VoIP system, these requests can take the form of a virtual phone dialer that rapidly makes simultaneous calls and clogs the phone lines.
Eavesdropping — This is the VoIP equivalent of wiretapping, and involves tapping into unencrypted calls. It allows unscrupulous individuals to intercept sensitive information such as credit card numbers, security questions and passwords.
Malware — Viruses, trojans and other forms of malware have been around for as long as computers have existed. VoIP systems rely on an internet connection and are therefore susceptible to malware.
We mentioned before that all telephone systems are inherently vulnerable. This is where a combination of best practices, robust security software and a reliable service provider come in. Practices such as the use of randomly-generated passwords and activating two-factor authentication add a layer of security. Using Virtual Private Networks (VPNs) and using only trusted networks make it even harder to hack your communications system. Most importantly, working with a systems provider that maintains system security through tools that allow system monitoring, along with regular software updates and periodic training for end-users, can go a long way in addressing such vulnerabilities.
