Vulnerabilities in your VoIP security can place your organization’s data and systems at considerable risk.
Though conducting regular audits can be frustrating, it goes a long way in safeguarding VoIP systems. However, not knowing what to look for can make efforts to secure your servers and data networks a lot more challenging.
Fortunately, we are here to help.
In this article, we share six of the most common VoIP security issues and how to prevent them, highlighting the benefits of using VoIP-hosted PBX by TelcoSolutions.
Not every organization worries about the details of its private network. However, every business needs to be aware of the risks its network faces.
In fact, learning about potential security vulnerabilities is one of the best things you can do for your organization’s longevity.
Here are six VoIP security issues and the steps you can take to prevent them.
Denial of service attacks occur when an individual ties up your network’s bandwidth and overwhelms it with fraudulent user requests. Eventually, your network will be unable to handle the overload and will shut down.
Such attacks can severely impact your company’s day-to-day operations and, ultimately, its bottom line.
Unfortunately, DoS attacks are becoming common since executing them has become cheaper and faster. However, you can implement various measures to protect your organization, including:
Like other internet-based applications, Voice Over Internet Protocol (VoIP) systems are vulnerable to malware.
For instance, hackers could infect your system with a virus, making it unusable. In extreme cases, certain malware can give cyber criminals complete access to your system, enabling them to steal sensitive information with relative ease.
The good news is that you don’t need special tools to protect your system from viruses and malware. The key lies in thinking ahead and developing a plan.
Consider implementing safety protocols, conducting routine audits, and ensuring your employees always comply with security measures. Monitoring traffic and using antivirus software and firewalls are other excellent ways of avoiding the damage malware causes.
VoIP vishing attacks seek to solicit a victim’s sensitive information through voicemail messages.
Picture one of your employees getting a call requesting them to visit a link to update their password. Your employee looks at the number, recognizes it, and decides to follow the instructions, not knowing an attacker spoofed the ID.
Before they know it, the employee has provided the attacker access to sensitive information that could compromise your organization.
The best way to protect your company from vishing scams is to always verify incoming call requests, including those that seem to be coming from within.
Additionally, educate your employees on the dangers of disclosing sensitive information over the phone without their supervisor’s expressed consent. You should also train your agents to ask for contact numbers and then call back as an extra layer of VoIP security.
Call tampering happens when a cybercriminal disrupts ongoing calls by delaying data transmissions or sending large amounts of data along the call path. These disruptions result in choppy connections and extended periods of silence, hindering your ability to conduct business.
The first step to protecting your telephony operations from such attacks is to enhance your authentication and encryption efforts.
For instance, your phones should have strong passwords and authentication codes. Additionally, ensure to encrypt all voice streams you send and receive.
Besides stealing sensitive information or compromising your network, attackers can also steal VoIP services. Once an attacker gains access to your VoIP phone system, they can use the service freely and leave you to cover the costs.
For instance, they can employ toll fraud, where they artificially generate high volumes of international calls to premium rate numbers and collect the revenue. Others may steal your billing information and use it to purchase expensive services.
Fortunately, you can put several measures in place to protect your system from VoIP service theft, such as:
Your company likely transmits sensitive information over the phone. For instance, your employees could ask customers for their credit card data and address.
Picture the damage an attacker could cause if they were to get access to such data.
One thing you can do to prevent eavesdropping is to ensure your calls have end-to-end encryption. In such a case, even if a hacker breaks into your system, they will be unable to decipher the data you transmit.
