VoIP (Voice over Internet Protocol) has been steadily replacing the traditional landlines and mobile phones for business use. VoIP for business is now becoming popular with small businesses and entrepreneurs preferring its cost-effectiveness and flexibility. But if you’re thinking about getting a VoIP phone system, you should also be aware of VoIP security issues.
Before getting a VoIP phone system for your business, it’s good to know about its advantages and disadvantages. The migration from legacy phone systems to VoIP is partly due to the inherent advantages of the technology and partly because of the changing demands of an increasingly remote workforce.
Remote-friendly solution: Traditional landlines are meant for physical offices or stores. Even with call forwarding, they’re at best sub-optimal. It’s difficult for customers or clients to reach businesses when employees work from their homes. But VoIP isn’t tied to a location or a device and can be used from any device as long as there’s an internet connection.
Lower installation and maintenance costs: Landlines and mobile phones require hardware. You need to buy the phone and associated hardware such as PBX if you want additional functionalities. You also have to pay high monthly fees. But it’s easy to add a business line to your smartphone with VoIP. All you need to do is download an app.
Higher scalability: If you want additional lines to your landline or mobile phone, you’ll have to buy more devices. When you use VoIP for business, you can give access to your team members, direct calls to multiple devices and easily add more numbers.
Enhanced features: The traditional systems cannot match VoIP phone systems in features. Without paying premium pricing, you can get auto-reply, business-friendly chat, voicemail and group broadcast.
While there are demonstrable advantages, VoIP for business also carries some risks. These are six of the most common VoIP security risks that businesses should be aware of:
Cybercriminals pose as representatives from banks or other institutions to get vital information from customers which would enable them to get into secured networks or get access to the individual’s bank account. Phishing usually happens over calls or messages and it is usually too late by the time users realise they have been under a cyber attack.
Distributed Denial of Service or DDoS happens when hackers overwhelm servers, making it impossible for you to use your VoIP system. Using multiple botnets or “zombie computers,” hackers render the system slow or congested by flooding it with requests for connection or data.
Another VoIP security risk is when hackers inject noise packets into a VoIP phone system’s network. This affects the quality of calls and makes it impossible to have seamless and clear conversations over the system. It would force people to disconnect the call and try again unsuccessfully.
Any application connected to the internet is at risk of malware and virus attacks. When injected into a VoIP phone system, these can take up network bandwidth and cause signal breakdowns. Other than corrupting the data, malware and viruses can also create Trojan entries for future attacks.
Voice over Misconfigured Internet Telephones (VOMIT) is the act of converting a phone conversation into a file to be transferred and used anywhere. This gives hackers access to private conversations and other crucial business data including usernames, passwords, call logs and financial information.
Spam over IP Telephony or SPIT is the VoIP version of email phishing attacks. Cybercriminals send pre-recorded voice messages to VoIP phone networks. While usually they clog the system, they can also lead to malware or virus attacks.
The VoIP security risks shouldn't suggest that the technology is unsafe for business use. With due diligence and a safety-first protocol, businesses can secure their VoIP phone systems from these cyberattacks.
Data encryption can help prevent hackers from gaining access to crucial business information. Using strong passwords will also make both individual access points and the network safer. Businesses should also train their staff to be on the guard against phishing attempts through messages or voice messages.
