Ways to protect against VoIP threats

Every business today uses Voice over Internet Protocol (VoIP) technology to enhance team collaboration. But while the benefits of VoIP continue to ease the burdens of business communications, there are VoIP threats and security risks associated with using it. Unsecure VoIP platforms may be harming your computer networks without you knowing it.

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 threats and 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 THREATS: 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 work within your organization.

Encryption tools for VOIP THREATS

Due to lack of encryption, VoIP systems can be easily broken into by hackers who can 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, in fact, adds a great layer of protection against VoIP 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.
