How to Protect a VoIP Phone System?

To protect your voice over IP phone system, you must first understand the common threats that VoIP systems face. Then, you can identify the signs of a VoIP security attack and take steps to resolve it.

VoIP System Vulnerabilities

Since small business VoIP or voice over IP systems work over the internet, they are more susceptible to hackers than traditional phone systems. However, thankfully, there are ways to keep your system secure even as it runs over the internet. So, what are some VoIP vulnerabilities to be aware of? Read on to learn more.

1. The wrong security systems
The tendency with new devices is to use default settings and passwords. However, that can leave room for security breaches. Configure VoIP credentials accurately and securely.

2. Using VoIP over random WiFi networks
Using VoIP on public or shared WiFi or internet networks can allow for easy hacking and security attacks. Use a secure home or office WiFi or business network for VoIP security.

3. VoIP phishing schemes
Phishing or scam VoIP calls occur when a caller pretends to be from a credible and legit business and inquires about sensitive information regarding your company. Avoid giving sensitive information over the phone to any party not directly affiliated with your business and report scams to your IT department.

4. Attacks on your business network
Similar to attacks via WiFi, a company’s business network can be hacked as well. Attacks on a business’s communication or internet network affect their voice over IP phone system security.

5. Viruses attacking the system
The internet is generally prone to malware and viruses, making its applications, software, files, and VoIP system vulnerable. To combat this, invest in reliable anti-virus and anti-malware software and ensure these are up to date.

6. Remote eavesdropping
When a system’s security has been breached, the hacker has the ability to listen in on calls and obtain sensitive data and information. This is referred to as “remote eavesdropping.” Data collected this way can later be used against your company.

Recognize Signs of VoIP Attack

So, how do you determine if your VoIP security has been breached and if you have been attacked or hacked? Here are some signs of a VoIP phone system security breach:

1. Huge and unexpected monthly bills
Hackers can make calls using an IP similar to your VoIP system’s IP. This lets them make calls that are charged to your account. And so, if you notice your phone bill has dramatically increased or has unexpected rates, then you need to check your system and account.

2. Unaccounted call history
Building on the above, checking your call history every few weeks or every month is essential. Unknown calls or random contacts need to be verified as a hacker might be using your VoIP system to make calls.

3. Internet searches redirected to random pages
Lastly, if your web searches end up on unknown or unwanted pages, then there’s a good chance there has been a security breach.

VoIP Security Strategies

Keeping all of this in mind, you may be wondering what you can do to maintain security and keep your VoIP system safe. Here are some helpful tips:

  1. Subscribe to a reliable VoIP service provider.
  2. Teach users to log out of their systems when they are done using them.
  3. Add strong passwords and update them every few months.
  4. Encrypt voice traffic and your WiFi.
  5. Use a business VPN that remote workers can also securely access.
  6. Purchase reliable anti-malware software and keep the software as well as equipment up to date.
  7. Run regular security checks on your entire system.
  8. Report suspicious activities.
  9. Educate users about VoIP security.

Keep Your Business Communication System Safe
Keeping your business phone system safe begins with education. Teach users and employees about safe internet usage and what activities can lead to breaches. Next, provide them with the right tools and updated software to keep their devices safe. Together, your company can avoid breaches and loss of sensitive information.
