VoIP systems can be vulnerable to a range of attacks, including call hijacking, eavesdropping and denial of service (DoS) attacks. All of these can cost your business money, not only in terms of putting it right, but also missed customer calls - not to mention your reputation.
In this day and age, cyber security is a hot topic. Making sure your VoIP (Voice over Internet Protocol) digital phone system doesn’t fall victim to hackers and other security threats is essential to your business success.
So what can you do to secure your VoIP digital phone system? Let’s take a look.
First off, use strong passwords
Make sure that the devices you plan to use with your VoIP system, including your smartphone, tablet or PC, have strong, unique passwords. A good mix of numbers, special characters and letters is recommended. Ask other members of your team to do the same, avoiding any passwords that are very common or easily guessable.
Have a top-notch firewall and network segmentation
Check that your VoIP network is behind a secure firewall and that access to your network is restricted. Only allow traffic from sources you trust, and block known malicious IP addresses. Also, separate VoIP traffic from other data traffic by segmenting your network. This will limit how far an attack can spread, helping you contain any security breaches.
Enabling encryption protocols like Secure Real-Time Transport Protocol (SRTP) is always a good idea. It means if a hacker was to intercept a voice call, they won’t be able to eavesdrop.
Update and patch your VoIP digital phone system regularly
Keep all your VoIP equipment up to date, including phones, tablets, routers and other hardware. Check regularly to see if there are any updates or patches from your VoIP equipment provider (choose bOnline and we can help you with this!)
Implement strong authentication
Wherever you can, use multi-factor authentication (MFA). This adds another layer of security to user accounts and access. It’s also worth limiting the number of failed login attempts, as well as having a documented lockout policy.
If you employ any team members who will be accessing or administering your VoIP system, spend time explaining issues like phishing attacks and password security to them. Also, encourage them to speak up if they think there’s anything suspicious..
Again, if it’s not just yourself using your VoIP phone system, make sure you know exactly who has access at all times. Consider limiting the number of users you have too.
Carry out security audits
Conduct security audits and penetration testing regularly (again, this is something we can help with) so that any weaknesses can be fixed before they become a problem.
