VoIP security is an important aspect that you must consider constantly. Even a single second of negligence can cause trouble regarding VoIP vulnerability. You should never see "being careful" as a waste of time.
VoIP vulnerability refers to problems that could compromise your company's communication network. If your network is open to threats, you will encounter many security problems, such as DDoS attacks.
Why should you pay attention to VoIP vulnerability?
Security should be your top priority as long as there is an internet connection. VoIP allows you to make calls over the internet. Naturally, you want all the information you share to remain confidential, no matter what circumstances apply to your company.
As cyber security attacks increase, your data is more likely to be compromised than before. When you experience a data breach, the loss you will suffer may be much more than anticipated. Because your company's reputation is weakened.
The old days are gone now. Communication with standard telephone lines gave way to VoIP. If you care about your company's communications efforts, you should be prepared for potentially problematic situations such as VoIP vulnerability.
Top 6 VoIP vulnerabilities
When you think of VoIP vulnerability, options such as malware or spam may come to mind. Even though these options are vulnerabilities, it should not be ignored that attackers use various methods to infiltrate the system.
SPIT: It stands for spam over internet telephony. It is generally related to spam calls. Marketing and advertising calls are prime examples. In SPIT attempts, all calls are made automatically.
Vishing: It usually spoofs calls from a particular corporate place. Attackers make telephone calls to request personal information. Vishing methods can be complicated to confuse the victim.
VOMIT: A type of VoIP vulnerability that targets misconfigured and weakly-secured networks. It is a simple plan for spam or identity theft attacks. After the system is infiltrated, other methods are implemented.
Call tampering: It refers to unauthorized access to a phone call made over VoIP. The data of the call can be captured during the transfer. It is also possible to record a call without permission at the destination.
Toll fraud: It is a type of fraud that targets international calls. After the attackers infiltrate a VoIP network, they start calling premium rate numbers. They reflect the entire cost of the calls to the network owner.
DDoS attacks: It is a type of attack in which the VoIP network is busy through the heavy traffic generated. The network becomes almost entirely unusable. Even a few seconds of service interruption can cause the company to suffer losses.
Suppose you are not using a VoIP firewall. In that case, you allow malware and viruses to infiltrate the network. Because of the lack of security, VoIP vulnerability becomes a bigger problem for you.
