As a more convenient and less expensive alternative to traditional phone services, Voice over Internet Protocol (VoIP) technology is now a business necessity. But as with any other piece of technology that can connect to the internet, VoIP can and will be exploited by cybercriminals. That’s why it’s important to take the necessary steps to protect your company’s VoIP systems, which include implementing the following vital security measures.
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. To avoid these security breaches, contract outsourced IT vendors to monitor network traffic for any abnormalities.
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 or SIP trunking, which is a recommended VoIP feature.
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.
VoIP systems that lack encryption can be easily broken into by hackers — even by amateur ones who can simply 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 won't be able to decode the file unless they have the decryption key.
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. Protecting the passwords themselves adds a layer of protection against threats. This can entail enabling multifactor authentication or using a password manager to generate and store an array of complex passwords.
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.
