How to Secure VoIP Communications for Business Continuity
Business VoIP communications are subject to security issues similar to online cyber attacks although at narrower scale. Taking preemptive measures to secure VoIP calls and data transfer is a good method to mitigate risks and limit the possible damages from a cyber attack on your business VoIP communications.
Common Security Breaches
The most widespread security issues may include phishing attempts. Usually, attackers are after confidential information or credentials to help them compromise other systems. Attackers may also use weak spots to upload malware on your computers and then use it for further attacks. You can eliminate the risk associated with malware up to 100 percent by switching to a cloud VoIP provider who takes full care about the antivirus security of the entire VoIP system.
Attacks that are specific to the VoIP niches pertain mostly to call hijacking or service theft. In a call hijacking scenario, an attacker would route calls to another location or would track your VoIP communications. The chance is good these data to be handed into the hands of competitors. Service theft is an activity where hackers route your service to an obscure service provider. You usually end up locked out of your VoIP account.
Just like in the case of malware, you can easily avoid call hijacking and service theft by using a hosted VoIP platform. In this case, the provider takes countermeasures against such attacks. If you are a VoIP service provider yourself, then you need to adopt advanced security tools to monitor for and counter any hacking attempts.
Adopt Encrypted VoIP Communications
A good number of VoIP providers offer encrypted messaging and data transfer for both business and personal communications. Even in this case you will make a wise move by encrypting further all business-critical communications. By encrypting your VoIP and data transfer over Internet protocols, you markedly minimize the risk of falling victim to call hijacking, ID spoofing, and service theft.
Another preemptive measure is to secure your wireless networks. Many businesses use Wi-Fi services as alternative to cable connections while a growing number of enterprises employ mobile staff where using Wi-Fi on mobile devices is unavoidable. You can prevent ID spoofing and hijacking by implementing only secured Wi-Fi connections. You can also introduce a mobile device management system to lock and block any stolen or lost device.

Your VoIP platform handles sensitive conversations and transmits sensitive business data all the time after all. The first step is to protect any sensitive options and user accounts with passwords.

The most crucial VoIP-related accounts are your VoIP service account, server access, and voice mails. Nonetheless, you must protect all related accounts to have completely secure VoIP service.
Most businesses are shifting to cloud-based VoIP services, so using a firewall to protect your side of the network is mandatory. The firewall will perform deep packet inspections (DPI) over all your communication packages. This way it identifies potential malware, viruses, spam, and even advanced tools such Trojan viruses.
Last but not least, educate your stuff do identify possible phishing attempts. They are aimed at persuading your employees to click on malicious links or reveal sensitive corporate information such as login credentials or access codes. VoIP systems are secure enough and cloud VoIP platforms offer advanced protection levels. No one can protect you against revealing credentials yourself, however.
Choose a reliable business VoIP provider to avoid potential data breaches due to poor configurations or unreliable software but bear in mind that taking preemptive measures is the best way to secure the VoIP service you use. Remember that a secure VoIP system is one of the components of your business continuity plan.
