Cyber security is of great concern, especially because more and more sophisticated mobile devices are being added to the network. There is every possibility of things going awry as miscreants can exploit vulnerabilities in the system and network to create problems. Digital threats are equally applicable to individuals as well as organizations. VoIP too is not untouched by these threats because it uses the internet for transmitting the calls. However, the good news is that the threats to VoIP can be easily identified and negated. In this post, we are going to have a look at the most imminent risks and ways to mitigate them.
VoIP Security Threats
Cyber threats to VoIP include risk to the network as well as the machines connected to it and these threats include trojans, viruses and even hackers. These attacks can affect the VoIP system as well as other digital equipment that is attached to the system. IP telephony is equally vulnerable to such threats and if proper cyber security measures are not taken, then it can lead to a lot of damage.
Eavesdropping
Phone conversations are highly vulnerable to eavesdropping and this includes both the traditional PSTN phone systems as well as the VoIP systems. However, to eavesdrop on a traditional PSTN system, people have to tap the phone lines or the switch. In case of VoIP, if a hacker is able to compromise the network security, he will get access to all the data packets. Now, these data packets can be easily converted into WAV files that can be played and listened to like any other normal audio file. Thus, network security should always take precedence while installing VoIP systems. .
Hacking of Free Services
The network tools that are available for free can be easily hacked and accessed by the people who have even little knowledge about the vulnerabilities of these tools. VoIP tools are susceptible to potential threats that can sneak into the network and hack the data packets.
Call Interception
Once the network security is compromised, the hackers will be able to intercept the calls and even get them redirected to other phones. The hackers can redirect the calls and wreak havoc on an organization by answering the calls.
Hacking Confidential Information
Often VoIP systems are connected to the CRM or other business applications, which can lead to data pilferage. Confidential information pertaining to your organization can be easily accessed by hackers if they are able to get into your network. They will sneak into your network and even get access to the linked applications. Thus, the names, addresses, phone numbers and even billing information of customers and employees can be acccessed without any suspicion.
Now that we have learnt about VoIP security threats, here are a few ways to safeguard it:
Install Firewalls
It is imperative to equip your network with the appropriate firewall security system that would protect your VoIP suite from any kind of threats. You will have to check with your IT team or IT consultant to find out the best firewall that suits your VoIP usage. This will not only help you to protect your system from any kind of evesdropping but also secure the network over which the communication takes place.
Encryption Tools
There are a variety of VoIP encryption tool that are available in the market, which help you to encrypt the data packets being transmitted over the internet. The best thing about encryption is that even if the hackers manage to break into the network, they won’t be able to use the data packets.
Stop Using Soft phones
Softphones are the easiest way to break into your network system because they are applications, which might have coding loopholes. It is better to avoid the use of softphones as they are not easy to monitor.
