VoIP systems are susceptible to attacks from hackers and cybercriminals, just like any other internet-connected device. Fortunately, by using recommended practices to safeguard your VoIP system, these cybersecurity dangers may be reduced.
In this post, we’ll examine the main VoIP security issues, VoIP system cybersecurity implementation strategies, and corporate cybersecurity protection strategies.
What Are the Threats to VoIP Systems’ Cybersecurity?
VoIP may be used to spy on calls, steal confidential information about your business or clients, or rack up astronomical phone bills. VoIP systems are another attack vector used by cybercriminals to get access to your internal networks and do further harm.
Once they have access to your VoIP system, hackers may commit a variety of frauds. Here are a few examples of the risks you can encounter.
Ticket Fraud
International calls made by cybercriminals using your VoIP account are charged to your account. They sometimes dial numbers they’ve set up to bill you for each minute you’re connected.
False Business Imitation (Spoofing)
When threat actors fake your company using your phone number, it is another typical hoax. For instance, they can phone your consumers and request payment details. Customers may be more susceptible to fraud since they are familiar with your phone number and believe in you.
Eavesdropping
Cybercriminals could be able to listen in on your calls or even record them if your data isn’t secured. They could be able to listen to your voicemails and search for private information that could be utilized in crimes.
Other Types of VoIP Attacks
Other types of VoIP attacks include:
- Distributed Denial of Service (DDoS) to overwhelm servers
- Man-in-the-Middle attacks for intercepting data in transit
- Spam over IP Technology (SPAM) to send recorded messages
- Packet sniffing to steal and record unencrypted data
- Voice over Misconfigured Internet Telephone (VOMIT) to convert conversations into files.
How to Know If You’ve Been Hacked
Reducing the cost of your phone service is one of the major advantages of adopting VoIP. You typically receive a constant and predictable monthly fee, so if your bill suddenly increases, thoroughly review it to search for any unusual behaviour.
Another red flag can be if international numbers start appearing in your call history even if you don’t do any business abroad. You might also want to examine to see if there are any unusually high numbers of calls coming in after hours. Different time zones are used by international actors.
How to Protect Against Cybersecurity Threats
You can protect yourself against cybersecurity threats by being proactive. That starts with making sure you’re working with the right VoIP provider.
Ensure End-to-End Encryption
The best VoIP providers will have multiple layers of security built into their systems, including end-to-end encryption. Transport Layer Security (TLS) and Secure Real-time Transport Protocol (SRTP) work together to provide high-level security during calls. When data is encrypted on every layer, even if calls are intercepted, the information will be unusable.
Enforce Secure Password Guidelines
To access your system, just one hacker needs to guess a password. Make sure administrators and staff members use secure passwords to prevent giving the bad guys an advantage.
Despite the fact that default passwords for phone systems are easily accessible online, many users neglect to change them. Never use the default passwords.
Restrict Remote Access
A virtual private network (VPN) can assist keep calls secret while someone is working off-site because of the rising number of remote employees and distributed workforce teams. Even while utilizing public Wi-Fi, this offers extra encryption and masks IP addresses.
To control access across all of your endpoints, you might also wish to use an SD-WAN with integrated security.
Attacks through VoIP May Have Serious Repercussions
Hackers can not only harm your company and lose you money, but they can also put your compliance at danger. You might need to comply with laws like HIPAA, PCI-DSS, Sarbanes-Oxley (SOX), Gramm-Leach-Bliley Act (GLBA), GDPR, CCPA, and others, depending on your business. Significant fines may be imposed for failing to take the necessary precautions to secure protected information.
Take proactive steps to safeguard your VoIP system, networks, and staff.
