The good news is that hackers can be kept out of a company’s VoIP system. And if you’ve already put something like that in place at your company, it isn’t too late to safeguard it. Continue reading to learn about the most frequent network risks and how to avoid them.
THE REQUIREMENT FOR VOIP PROTECTION
To work successfully, all VoIP system needs reliable internet connectivity. Unfortunately, their online dependability renders them subject to various security vulnerabilities.
Some of the more common ones are:
SECURITY RISK #1. REJECTION OF SERVICE
Denial of Service (DoS) is a prevalent threat to VoIP systems that consists of assaults attempting to shut down a computer or network and render it inoperable.
Authorized VoIP users can also not access their information systems and devices if this occurs. Reduced audio quality, availability, and delay can also damage call centres.
SECURITY RISK #2. WAR DIALLING
War dialing is a type of attack in which the attacker takes charge of the company’s private branch exchange (PBX) and hunts for alternative phone networks. This implies that hackers can call numbers, connect to modems, and use other extensions.
SECURITY RISK #3. TOLL FRAUD
Toll fraud is a risk that involves making calls to external numbers using a company’s current infrastructure.
For example, hackers may dial expensive foreign lines to rack up toll costs against your company.
SECURITY RISK #4. PHISHING
This is a prevalent risk in which attackers send false communications to deceive victims into disclosing important information. Frequently, the naïve victims would provide passwords, internal IP networks, and other confidential material.
SECURITY RISK #5. MALWARE
It’s a danger in which attackers send harmful software to victims through email or phone. A file or code is sent over a network to infect, steal, or examine the information stored within a system.
After compromising the system with malware, VoIP hackers might infiltrate your network and obtain critical business information.
SECURITY RISK #6. INTERCEPTION OF CALLS
The call interception attacker intercepts Session Initiation Protocol (SIP) communication, which is used to begin, manage, and discontinue real-time voice and video connections through unprotected networks.
.A victim of a call interception assault could, for example, be diverted to a hacker-hosted line.
6 WAYS TO IMPROVE VOIP SECURITY
Given the range of vulnerabilities attackers provide to VoIP systems, it is critical to enhancing your VoIP security as soon as possible.
Here are six helpful hints to get you going.
TIP #1. A FIREWALL SHOULD BE SET UP
All VoIP systems require secure firewalls. Your VoIP software and hardware firewalls must check every piece of data that enters and exits the strategy that ensures its security.
If you get spam or danger, the firewall would recognize it and seize command of it, protecting your system from the attack.
Also, a good firewall will allow the data packets you send to travel unhindered.
TIP #2. USE A SECURE PASSWORD
Your VoIP system isn’t unique from any other piece of software or platform you employ to handle sensitive data. As a result, it must be safeguarded by secure and periodically changed passwords.
Consider making 12 character combinations, comprising numbers, upper- and lower-case letters, and special symbols. Furthermore, for maximum security, use passwords made up of a randomized sequence of characters.
It’s critical to create a password when you set up your VoIP system. Otherwise, you’ll probably forget about it afterward.
Also, remember that certain VoIP phones come with pre-set, frequently public passwords. That is why you should alter yours as soon as possible.
Passwords should be changed every 3three months.
TIP #3. CALLING RESTRICTIONS
Toll fraud is the cause of many VoIP cyberattacks. So, if your company operates locally, you don’t need to activate the overseas call option. This helps you be extra cautious and avoid paying exorbitant costs for which you were not even liable.
To minimise toll fraud, you can have your VoIP provider restrict 1-900 numbers.
TIP #4. INSTRUCT YOUR TEAM TO INVESTIGATE ANY QUESTIONABLE BEHAVIOUR.
Many VoIP assaults are the result of the careless activity. To avoid this, educate your personnel on accomplishing their jobs without jeopardizing the system’s security.
First, they should understand how to detect odd anomalous network activity, manage passwords, and report questionable conduct. They must also identify any phantom calls or missed voicemail messages. Employees must also avoid keeping voicemails for an extended period.
The fact is that cybersecurity awareness at onboarding isn’t always sufficient. That is why you should be conducting regular training to maintain your VoIP security.
TIP #5. DISABLE THE USE OF WEB – A BASED INTERFACE
The web interface for your VoIP system should preferably be turned off.
Why?
Using phones on a computer exposes a vulnerability to hackers. It just takes one phone user to fall victim to revealing the entire network to an outside entity. Consequently, all of your data in text format might be taken.
So, unless it becomes essential for you to utilise the web-based interface, be careful about keeping it as safe as possible.
TIP #6. REMOTE WORKERS SHOULD USE A VIRTUAL PRIVATE NETWORK.
Virtual Private Networks (VPNs) are excellent software applications that secures data irrespective of where your personnel is located.
You can set up a network like this for your remote employees to avoid data leakage and intrusions. The incredible thing is that using this service will not impair voice quality.
