9 Best Practices to Strengthen Business VoIP Security

As VoIP becomes the standard for business phones, voice infrastructure is facing increased risk from attacks by cybercriminals and scammers. Vishing, DDoS attacks, hacking, malware and keystroke detection are just some of the network vulnerabilities being exploited by bad actors.

There are a lot of very good reasons why more businesses are moving to VoIP solutions. VoIP is cheaper, has greater functionality and can be integrated with many other digital applications, including those in the cloud. However, like any technology that involves the transfer of data over the Internet, it can be intercepted.

Cybercriminals understand that because security personnel are more focused on preventing attacks on other business-related infrastructure, voice networks are often overlooked. The Mutare Voice Network Threat Survey found that nearly half of all organisations experienced a vishing or other social engineering attack in the previous year.

Which is why every business should take appropriate steps to ensure that voice networks are just as protected as other connectivity infrastructure.

The importance of VoIP security cannot be understated. However, there is plenty you can do right now to ensure your business phone infrastructure is protected.

1. Training

First and foremost, as part of an overall cybersecurity awareness initiative, make sure all your people understand the dangers posed to voice networks, are able to recognise the signs of potential attacks and are required to report incidents. Many of the following practices for safeguarding your voice systems will only help if your employees fully contribute to your efforts.

2. Use multi-factor authentication

Staff should adopt best practices when setting passwords. Adding expiration dates for passwords, so they’re regularly updated, along with two-factor authentication will greatly increase VoIP security.

3. Firewalling

Just like other business critical devices and systems, your VoIP and associated voice network infrastructure should be shielded behind your corporate firewall. That should allow you to monitor and block any unauthorised activity.

4. Keep software updated

Updating your software is vital when it comes to online devices. That applies to VoIP phone systems too. Updates often contain important security upgrades to mitigate against known and emerging threats.

5. Monitor call logs

One of the best ways to protect your VoIP system is to monitor it. By analysing call logs, you can see where threats or suspicious behaviour may be coming from and take action to block it.

6. Remote workers should use a VPN

Employees working from home open up an array of security vulnerabilities. If logging into a company phone system, a VPN will protect remote workers from external threats.

7. Encryption

While most VoIP solutions come integrated with encryption capabilities, not all offer full end-to-end encryption. Talk to your provider about the VoIP security capabilities available within your solution and make sure you’re protected. If not, look to communications providers, such as DigitalWell, that can tailor your solution to the security needs of your business.

8. Don’t neglect compliance

Regulatory rules are constantly being updated. Make sure your provider can help you stay compliant, based on the needs of your sector.
