Voice over Internet Protocol (VoIP) technology has vastly improved team collaboration. VoIP systems, however, are not immune to a variety of cyberattacks. And because VoIP-based threats are not as well-known as ransomware, phishing mail, and other more recognizable attacks, organizations tend to be lax toward securing their communications systems. Follow these tips to protect your devices and VoIP tools.
What many companies don’t realize is that valuable information moves across VoIP networks just like sensitive data is shared via email. In some cases, internet-based calls are more vulnerable to fraud, identity theft, eavesdropping, intentional disruption of service, and even financial loss. With numerous VoIP-based attacks, it’s crucial to implement these security measures now.
24/7 monitoring
VoIP security breaches usually take place outside operating hours. Attackers make phone calls using private accounts or access call records with confidential information on the sly. Contract outsourced IT vendors to monitor network traffic for any abnormalities to avoid these security breaches.
Virtual private networks
Virtual private networks (VPNs) create a secure connection between two points, as if they belong in the same closed network. It’s like building a safe secret tunnel between you and the person you’re calling. Using a VPN can also help overcome complications involving Session Initiation Protocol trunking, a recommended VoIP feature.
VoIP firewalls
Firewalls specifically designed for IP-based telephony curb the types of traffic that are allowed into your network. They ensure that every connection is properly terminated at the end of a session and identify suspicious calling patterns. Virtually every VoIP vendor provides these protocols, but you should always consult with your IT services provider as to how these protocols will be managed within your organization.
Encryption tools
Due to lack of encryption, VoIP systems can be easily broken into by even inexperienced hackers who can download and deploy tools to eavesdrop or intercept your calls. Some services claim to have built-in encryption, but companies still need to be vigilant and investigate how effective these are.
Using encryption ensures that even if hackers successfully download audio or video, they still can’t decode the file unless they have the decryption key.
Password protection
Using passwords to authenticate your access to private information is not as secure as it once was. Hackers can easily guess a password and use it for cyberattacks. This is why protecting the passwords themselves adds a great layer of protection against threats.
Employees should never divulge any compromising information during a VoIP call, as eavesdropping is one of the easiest and most common cyberattacks against VoIP networks.
VoIP is as important as any of your other network security considerations. It requires a unique combination of protection measures, and we’d love to give you advice on these. Give us a call today to get started.
