There will always be those who seek to use a technology’s notoriety for nefarious ends whenever a new one emerges. This is commonplace with smartphones running the most popular operating systems, such as Android and iOS, and is now also becoming commonplace with VoIP systems. Depending on the expertise and will of the hackers, there are numerous ways to exploit a VoIP system. The versatility and strength of VoIP phones create multiple entry points for criminals and competitors who wish to harm your firm by severing your communications.

There are numerous vectors for attacking computer systems. However, in most cases, hackers will not gain anything by attacking random businesses. Even if they succeed in stealing sensitive information, it may not be immediately beneficial to them. However, because a compromised VoIP system can benefit anyone, every business is at risk of being attacked. Criminals often focus their efforts on international calls, and when they break into your communications and start using your VoIP systems, the resulting costs can be enormous.

Instances of similar violence are occurring all around the globe. Additionally, unlike the traditional telephone system, which was more restricted to a certain area, VoIP is Internet-based, making it vulnerable to attacks from anywhere in the world. While VoIP phones are incredibly powerful, that same strength can be used against it if the network is not “hardened,” as was described above.

The actions of competitors are another cause of VoIP hacking. The impact of a disruption to a company’s communications infrastructure is much greater than that of a website outage. When your website is down, you may still be able to serve customers. To do this, hackers frequently employ distributed denial of service (DDoS) assaults, in which they overwhelm a server with fake requests.

For Those Who Are Unfamiliar, What Is VoIP?

The term “Voice over Internet Protocol” (VoIP) refers to a protocol that allows for transmitting voice and other types of multimedia communications over the internet. Making and receiving calls and text messages using an internet connection rather than a standard phone line is supported.

Security for VoIP calls is crucial since it helps to ensure that all VoIP calls remain private, intact, and accessible at all times. VoIP security can be compromised in a number of ways.

Eavesdropping:

In the case of voice-over-Internet protocol (VoIP) discussions, eavesdropping happens when an unauthorized third party listens in on the conversation without the parties’ knowledge or consent.

Spoofing:

An example of spoofing is when an attacker gains access to the VoIP system while pretending to be a legitimate user.

Denial of service (DoS) attacks:

In an effort to render the VoIP service unavailable, attackers sometimes resort to denial of service (DoS) operations.

Defense Against Threats

Multiple safeguards can be set up to counteract these dangers:

Encrypting VoIP communications:

Protection against eavesdropping is bolstered by encrypting VoIP transmissions. As this makes it exceedingly challenging for third parties to intercept and decipher the talks.

Implementing authentication:

By demanding a username and password from users before they can use the VoIP system. Authentication helps reduce the risk of spoofing.

Deploying firewalls:

Firewalls, which filter out malicious traffic, can be set up to help against denial-of-service assaults.

In addition, it is crucial to always have the most up-to-date security updates installed on your VoIP software and hardware.

Final Words

Of course, VoIP phones network can be secured in several ways. You have the option of segmenting traffic, enforcing stringent password requirements, etc. However, you’ll need in-depth technical understanding and ongoing monitoring to stay ahead of the current threats to VoIP systems. The vast majority of companies just do not have the means or the manpower to devote to such an endeavor. Because of this, a hosted VoIP system is the best option for most businesses. When you outsource your infrastructure, experts will manage it and take on the burden of difficult security tasks on your behalf. This allows you to concentrate on running your company and satisfying your clients.
