How to prevent VoIP threats

Now that digital collaboration is an integral part of any business, VoIP has become indispensable. Unfortunately, as it becomes more widespread, so do the threats against it. These attacks may not be as serious as ransomware or phishing, but they’re just as dangerous to SMBs. Here are five ways to protect your VoIP network against these threats.

Since the majority of VoIP services involve live communications, people might think that it’s safer than stored data, which can be stolen at any time. What companies don’t realize is that valuable information moves across VoIP networks the same way sensitive documents are 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.

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. Contracting outsourced IT vendors to monitor network traffic for any abnormalities is the best way to avoid these security breaches.

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 they are.

Using encryption ensures that even if hackers successfully download individual audio or video, they still can’t decode the file unless they have a separate decryption key.

Virtual private network

Virtual private networks or VPNs create a secure connection between two points, as if they are occupying the same closed network. It’s like building a secret tunnel between you and the call receiver. Aside from encryption, establishing a VPN can help overcome complications involving Session Initiation Protocol trunking, a recommended VoIP feature.

Password protection

Using passwords to authenticate your access to private information is not as secure as it once was. Hackers can easily find or guess a password and use it for cyberattacks. This is why protecting the passwords themselves is a great layer of protection against threats.

Employees should be instructed never to give 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.

ThreatLocker:

ThreatLocker is a zero-trust endpoint security tool giving companies control over what software can run, by whom, and what data can be accessed.

It keeps a full detailed audit of what applications are used and data accessed/transferred/deleted and by what users (signature tracking, etc.) If something unusual happens, such as a signature change, or a user opens an application that is out of their normal routine the administrator is alerted. This is a crucial tool in identifying malware threats, as well as helping organizations identify if users are accessing applications and/or data/ files they should not be.

ThreatLocker provides a solution that allows businesses to control the content that runs on their network. Unlike AntiVirus software ThreatLocker is not looking for known viruses or malware. ThreatLocker uses a complex set of rules to determine what can be executed on a network and stops anything that has not been approved before it can even execute.

Huntress:

Huntress is a supplement to SentinelOne. Hackers are becoming more sophisticated, and Huntress actively seeks out these threat actors with a "defend forward" mentality. This software combines both advanced security tools along with human intervention to ensure even the most advanced hackers can't penetrate your network.

SentinelOne:

SentinelOne is a comprehensive enterprise security platform that provides threat detection, hunting, and response features that enable organizations to discover vulnerabilities and protect IT operations. SentinelOne integrates static artificial intelligence (AI) to provide real-time endpoint protection and reduce false positives that derail investigations or make threat detection a capital-intensive process. This will replace Webroot in your current environment.
