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.
1. Set up a firewall
If spam or a threat comes your way, the firewall will identify and gain control over it, shielding your system shielded from the attack. A good set-up will allow the data packets you send to travel unhindered.
2. Use strong passwords
Use randomly generated passwords consisting of at least 12 characters
including numbers, upper- and lower-case letters and symbols. Most VoIP phones come with pre-set passwords, often available publicly,change these immediately.
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. You should also block 1-900 numbers to avoid toll fraud.
4. Encourage your team to report suspicious behavior
You should hold periodical Cybersecurity Training to keep your environment safe at all times. Train your employees how to spot unusual network activity and report suspicious behavior.
5. Deactivate web interface use
Unless it’s absolutely necessary fornyou to use the web interface, be sure to secure it very strictly. 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.
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. A well configured VPN won’t degrade the call quality.
