6 Tips for Boosting VoIP Security
Given the variety of threats imposed by attackers on VoIP systems, it’s necessary to optimize your VoIP security ASAP.
Here are 6 valuable tips to get you started.
TIP #1. SET UP A FIREWALL
Secure firewalls are necessary for all VoIP systems. It’s important to make your VoIP software and hardware firewalls scan information that goes in and out of the system to ensure it’s secure.
If spam or a threat comes your way, the firewall will identify and gain control over it. Shielding your system from the attack.
Also, a good firewall will allow the data packets you send to travel unhindered.
TIP #2. USE STRONG PASSWORDS
Your VoIP system is no different from any other software or platform you use for handling sensitive information. For this reason, it needs to be protected with strong and regularly updated passwords.
Aim for combinations of at least 12 characters, including numbers, upper- and lower-case letters, and special symbols. And for ultimate protection, go for passwords consisting of a random character series.
It’s crucial to set a password as soon as you configure your VoIP system. Otherwise, you’re likely to forget about it later.
Also, remember that some VoIP phones come with pre-set passwords, often available publicly. That’s why you should change yours as soon as you get a chance.
Ideally, try to change your passwords every three months.
TIP #3. RESTRICT CALLING
Many VoIP attacks happen due to toll fraud. So, if your business runs locally, there’s no need to have the international call option enabled. This allows you to be on the safe side and avoid paying expensive bills you weren’t even responsible for making.
You can let your VoIP service block certain numbers to avoid toll fraud.
TIP #4. ENCOURAGE YOUR TEAM TO REPORT SUSPICIOUS BEHAVIOUR
Many of the VoIP attacks arrive due to irresponsible behavior. To prevent this from happening, educate your team on how they can best do their job without affecting the system’s security.
For starters, they should know how to spot unusual network activity, handle passwords, and report suspicious behavior. They should also report ghost calls and missing voicemails whenever received. Staff also shouldn’t store voicemail for too long.
The reality is that sometimes, cybersecurity training during onboarding often isn’t enough. That’s why you should do periodical training to keep your VoIP safe at all times.
TIP #5. DEACTIVATE WEB INTERFACE USE
Ideally, you should deactivate the web interface used for your VoIP system.
Why?
Using phones on a desktop computer opens an area of weakness to attackers. It's enough for a single phone user falling prey to leave the whole system exposed to an external party. All your data can be stolen in text format as a result.
So, unless it’s absolutely necessary for you to use the web interface, be sure to secure it very strictly.
TIP #6. USE A VPN FOR REMOTE WORKERS
Virtual Private Networks (VPNs) are great software that encrypts traffic regardless of your employee’s location.
You can set up such a network for your remote staff to prevent data leaks and breaches. The good news is that using this service won’t degrade the call quality.
(Re)gaining Control Over Your VoIP Security
VoIP systems are a fantastic alternative to landlines. After all, they offer many more features and flexibility at a fraction of the cost. However, their reliability on the internet also makes them susceptible to cyberattacks.
If you have just set up a VoIP system for your company or are thinking of starting one, securing it should be your number one priority. Don’t risk falling prey to toll fraud, malware, phishing, and other attacks. Take some time to secure your business by following the tips from this article.
