Common Security Threats That VoIP Faces And How to Minimise Them

by Andrew Lope Business promotion

Irrespective of the size of the business, business owners are always searching for technologies and ideas to reduce business communication expenses. VoIP has emerged as a very cost-effective solution, as it does not incur too much expense. However, people are always very much concerned about the security of the VoIP network. Vendors of Jabra evolve 75 solutions also add that maximising and updating VoIP is essential to keep it secure and safe.

Why Is Voip Security Important?

No matter what business communication solution you are using for your business, security always remains the most significant factor. It also plays a prominent role in any business's success, and this applies to VoIP as well. The reason why VoIP is trending in the news is that it is flexible and dynamic and offers a hybrid working solution.

What Are The Main Threats That Voip Faces?

Common security threats that arise in VoIP are call interception, ID smoking and denial of service attacks. There are other risks as well, and we have explored the details in this post.

Malware

Vendors of Jabra evolve 2, and solutions like Jabra pro 920 say that just like several other unified communication solutions, VoIP is also exposed to malware-related threats. The original malware 'Wannacript' and all its derivatives have revealed that they are a significant threat to telephone systems and computer systems used in businesses. They can initiate ransomware attacks and can ensure maximum damage during cyber-attacks.

Malware attacks don't come from telephone systems but from a corrupted document or email or something similar opened on any devices connected to a unified communication solution. Vendors of Jabra evolve 75 advocate that with extra vigilance and awareness, businesses can minimise malware attacks to zero.

Denial Of Service

VoIP solutions also face the risk of 'denial of service attacks, and these attacks are designed to shut down the machine or the entire server. They are carried out by flooding the desired target with traffic or overloading it with information that can generate a complete server crash. Talking about VoIP, cybercriminals can initiate a 'denial of service' attack by sending high concentrations of information on the network, such as spamming phone calls.

Phishing Scams

You will find VoIP networks getting targeted by phishing scams where scammers contact users and leave a message about any suspicious activity. The victim is then taken on another call, where they are asked to verify their identity and hand over confidential details. Small businesses can easily avoid these attacks by training employees regularly about typical scamming tricks and ensuring that they flag every suspicious activity on the VoIP network.

Call Tempering

VoIP systems are always assumed as vulnerable to call tempering because hackers try to disturb real-time calls there. This can interrupt the call quality and cause long delays or periods of silence. During this time, they seek opportunities to share substantial amounts of data over the line.

Vomit

Another threat that small businesses face very commonly for VoIP networks is VOMIT or VOICE OVER MISCONFIGURED INTERNET TELEPHONE tools. In this attack, cybercriminals will steal voice snippets and also confidential and sensitive information from your business calls. These attacks are dangerous as cybercriminals can quickly gain access to your confidential data, and as a result, it becomes easier for them to eavesdrop on future calls and other communication solutions. Business owners can prevent these attacks by securing the data and sensitive information from cyber-criminals.

How To Secure Your Voip System?

VoIP is undoubtedly highly secure, but there is nothing wrong with boosting security and familiarising people with it. For example - Session Initiation Protocol or SIP can act as a more advanced and secure solution compared to PSTN or Public Switched Telephone Network or PBX or Private Branch Exchange. The following processes can also be used to make VoIP communication more secure for small businesses.

Encryption
