5 Vital VoIP measures to implement

Voice over Internet Protocol (VoIP) technology is a flexible, scalable, and highly efficient communication solution that more and more modern businesses are relying on. However, a large user base makes VoIP an attractive cybercrime target, which means VoIP users face increasing risks. Here are five effective security measures you can implement to protect your business’s VoIP systems and devices from various threats.

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. 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.

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

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.

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. 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.

What you need to know about telephony DoS

Hackers launch denial-of-service (DoS) attacks to render IT systems and networks inaccessible to intended users. Large corporations’ web servers used to be frequent targets, but nowadays, every business can become a victim. Hackers have also started launching attacks on Voice over Internet Protocol (VoIP) systems. This brief guide on telephony DoS attacks can help you become better prepared.

Denial-of-service attacks

The end goal of any DoS attack is to overwhelm a system with so many requests that it is eventually forced to shut down. Telephony DoS (TDoS) attack is a subcategory leveled at VoIP systems. Alarmingly, this attack is commonly used against hospitals and 911 phone lines. Some TDoS attackers even demand a ransom to halt the attack, which is similar to ransomware attacks. They take advantage of cryptocurrencies and caller-ID spoofing to make it incredibly difficult to identify attackers.

TDoS attacks generally employ fewer resources than the DoS attacks that are designed to cripple IT systems, which include networks, servers, and software. At its most basic, a TDoS attack requires only an automated phone dialer that calls a target phone number and hangs up — over and over. That very simple strategy can stop anyone else from getting through the line.

What organizations need to do

While your first instinct may be to lock down your VoIP system with complicated security measures, doing so will only do more harm than good. Most businesses can’t operate if they can’t communicate with their customers, business partners, and other third parties.

Although VoIP may be a digital resource similar to other components within your IT systems, the very nature of phone lines makes hiding them behind firewalls and other protections impossible. Fortunately, there are now new security protocols that can protect your communication infrastructure against those who try to use force to gain access to your directory information. These protocols can also identify, reroute, and filter calls coming from known attackers. Get in touch with our team to learn more about these protocols.

If you’re experiencing any abnormalities with your VoIP system, or if you want to deploy the most advanced solution that the market has to offer, our expert team of IT professionals is ready to help you at the drop of a hat — just call today.
