Hardly any phone call system in a business beats VoIP when it comes to efficiency and flexibility. However, it’s not immune to cyberattacks. Discover how you can secure your VoIP ASAP.

What kind of communication system are you using for your business?

I asked because many modern-day businesses have now switched to the Voice Over Internet Protocol (VoIP). This technology allows employees to perform voice calls using only their internet connection. 

It’s often a wise choice considering that using VoIP comes with several benefits to a business.

Among its benefits include lower operating costs, greater convenience than traditional services, increased accessibility, higher scalability, and the ability to multitask. VoIP also comes with advanced features for teams of all sizes, is completely portable, and offers superior voice quality. 

However, VoIP systems also have limitations, with cyberattacks being their number one downside. 

The good news is that it’s possible to protect a business’s VoIP system from hackers. And if you already implemented this in your business, it’s not too late to secure it.

Read on to discover the most common threats to your network and tips on preventing them.

The Need for VoIP Protection

All VoIP systems require a stable internet connection to function properly. Unfortunately, their reliability on the internet makes them vulnerable to various security issues.

Some of the most frequent ones include:

Security Issue #1. Denial of Service

Denial of Service (DoS) is a common threat to VoIP systems comprising attacks designed to shut down a machine or network and make it inaccessible for use. 

When this happens, legitimate users of VoIP technology may not be able to access their information systems and devices. And call centers can be affected by lower call quality, uptime, and latency. 

Security Issue #2. War Dialling

War dialing is an attack that controls the company’s private branch exchange (PBX) and scans for other phone networks. This means hackers can dial numbers and connect to modems and other extensions.

Security Issue #3. Toll Fraud

Toll fraud is a threat that consists of making calls to outside lines from a company’s existing system. 

For example, hackers will dial costly international numbers intending to rack up toll charges to your business. 

Security Issue #4. Phishing

This is a common threat wherein attackers send fraudulent messages designed to trick victims into revealing sensitive information. Often, the unsuspecting victims would divulge information about passwords, internal IP networks, and similar data. 

Security Issue #5. Malware

It’s a threat where attackers install malicious software via email or phone. A file or code gets delivered over a network and has the goal of infecting, stealing, or exploring the information contained within a system. 

After infecting the system with malware, VoIP hackers can enter your network and access critical business information. 

Security Issue #6. Call Interception

The call interception attacker uses unsecured networks to intercept the Session Initiation Protocol (SIP) traffic that serves to initiate, maintain, and terminate real-time voice and video sessions. 

A victim of a call interception attack can be redirected to another line hosted by the hacker, for example.

6 Tips for Boosting VoIP Security

Given the variety of threats imposed by attackers on VoIP systems, it’s necessary to optimize your VoIP security ASAP. 

Here are 6 valuable tips to get you started.

Tip #1. Set Up a Firewall 

Secure firewalls are necessary for all VoIP systems. It’s important to make your VoIP software and hardware firewalls scan information that goes in and out of the system and ensure it’s secure. 

If spam or a threat comes your way, the firewall will identify and gain control over it, shielding your system shielded from the attack.

Also, a good firewall will allow the data packets you send to travel unhindered. 

Tip #2. Use Strong Passwords 

Your VoIP system is no different from any other software or platform you use for handling sensitive information. For this reason, it needs to be protected with strong and regularly updated passwords. 

Aim for combinations of at least 12 characters, including numbers, upper- and lower-case letters, and special symbols. And for ultimate protection, go for passwords consisting of a random character series. 

It’s crucial to set a password as soon as you configure your VoIP system. Otherwise, you’re likely to forget about it later. 

Also, remember that some VoIP phones come with pre-set passwords, often available publicly. That’s why you should change yours as soon as you get a chance. 

Ideally, try to change your passwords every three months.

Tip #3. Restrict Calling

Many VoIP attacks happen due to toll fraud. So, if your business runs locally, there’s no need to have the international call option enabled. This allows you to be on the safe side and avoid paying expensive bills you weren’t even responsible for making. 

You can let your VoIP service block 1-900 numbers to avoid toll fraud. 

Tip #4. Encourage Your Team to Report Suspicious Behaviour 

Many of the VoIP attacks arrive due to irresponsible behavior. To prevent this from happening, educate your team on how they can best do their job without affecting the system’s security. 

For starters, they should know how to spot unusual network activity, handle passwords, and report suspicious behavior. They should also report ghost calls and missing voicemails whenever received. Staff also shouldn’t store voicemail for too long. 

The reality is that sometimes, cybersecurity training during onboarding often isn’t enough. That’s why you should do periodical training to keep your VoIP safe at all times. 

Tip #5. Deactivate Web Interface Use 

Ideally, you should deactivate the web interface used for your VoIP system. 

Why?

Using phones on a desktop computer opens an area of weakness to attackers. It’s enough for a single phone user falling prey to leave the whole system exposed to an external party. All your data can be stolen in text format as a result. 

So, unless it’s absolutely necessary for you to use the web interface, be sure to secure it very strictly.

Tip #6. Use a VPN for Remote Workers

Virtual Private Networks (VPNs) are great software that encrypts traffic regardless of your employee’s location. 

You can set up such a network for your remote staff to prevent data leaks and breaches. The good news is that using this service won’t degrade the call quality. 

(Re)Gaining Control Over Your VoIP Security

VoIP systems are a fantastic alternative to landlines. After all, they offer many more features and flexibility at a fraction of the cost. However, their reliability on the internet also makes them susceptible to cyberattacks. 

If you have just set up a VoIP system for your company or are thinking of starting one, securing it should be your number one priority. Don’t risk falling prey to toll fraud, malware, phishing, and other attacks. Take some time to secure your business by following the tips from this article.

Printing devices are often overlooked when it comes to security. But the reality is, cybercriminals can hack your printer to get confidential information.

Your printer is probably the last piece of computer equipment you thought needed protection from cybercriminals. 

But the truth is very different. 

Attackers actively try to locate the weakest links in security to gain access to and exploit valuable data. And among the weakest links is the printer.

The thing with printers nowadays is that they have access to your devices, network, and the internet. This new open-access functionality makes them an ideal target for cyberattacks. 

Unfortunately, many business owners overlook the importance of securing their printers and mainly focus on computers and mobile phones. 

Most people still perceive printers as internal devices that serve basic functions. For this very reason, they are an easy target for cybercriminals.

Other than performing unauthorized print jobs, hackers can access confidential information as well as all connected computers and networks all through a printer. 

You may also not be aware of the amount of valuable data your printer can store about you – tax files, bank details, financial records, employee information, personal information, etc. All a hacker needs to do is get into the operating system of your printer, and they can collect this sensitive data. 

If you’ve just realized the importance of securing your printer, keep reading. This article shares eight tips to help you do just that.

The 8 Tips

Tip #1. Make Sure Your Printers Are Configured Correctly

Many things can make a printer vulnerable to cyber threats and security breaches. So, you want to get the basics right to ensure the attacks don’t happen to you. 

To start with, make sure to change the default password on your printer. Since anyone can access a printer remotely, a simple “123456” code won’t suffice. 

Second, make sure you’re using your own router to print files remotely. Never connect to “Guest” networks.

Tip #2. Inspect Print Trays Regularly

This one is a no-brainer, but everyone could use it as a reminder. Make sure to check your print trays and get rid of unused pages carrying sensitive information. There’s no easier way to prevent data leaks than this. 

Alternatively, you can get a shredder for your office and shred the papers you don’t want anyone to see.

Tip #3. Install Malware and Firmware Updates

Invest time and effort to ensure that your malware and firmware protection are up to date and can handle all types of hacks. 

The good news is that many printers come with pre-built malware protection. 

HP, for example, installs the HP “SureStart” software in their printers that monitors approaching targets when the printer is on. The software can shut down the device if an attack comes its way. This is a great way to prevent attacks from spreading further within the network. 

Tip #4. Limit Access to the Network

Unprotected printers in a network are an extremely easy target for cybercriminals. Sure, businesses and offices require printers to access networks to perform remote prints. But if you can do the job by disabling the network access, make sure you do that. 

If not, tweak the printer and network settings to only allow the device to take print jobs from the network you trust. This will help avoid outside interference and security breaches. 

Tip #5. Update Your Printers

Updating a printer is equally as important as updating your phone to the latest software. Much in the way iOS developers look for bugs and fix them in a new update, printer manufacturers work toward known device vulnerabilities and update the software for added protection. 

Look for printer updates so you can easily overcome known threats to the printer. Ideally, update your printers every quarter to get the most out of the security benefits. 

Tip #6. Install a Firewall

If you run an office, chances are you already have a firewall. But in case you missed this requirement, now’s the time to do it. 

Using a reliable firewall helps keep printers safe from cybercriminals. 

Your computers most likely come with pre-built firewalls, and all you need to do is keep them enabled. But there are also specialized firewalls for homes and offices that offer advanced security and make it virtually impossible for anyone to break in. 

Tip #7. Encrypt Your Storage

Printers with shared networks can perform distance printing. And when a print job is in transit and travels from a computer to a printer, hackers can intercept the data and exploit it. 

To keep this from happening, encrypt your print jobs. Also, make sure the sensitive data on your printer’s hard or internal drive is encrypted as well.

Keep in mind that when you print a document, that file is often stored as an image within the printer and makes it an easy target for hackers. It’s why you should use an encryption tool to protect your data. Luckily, many modern printers have this tool pre-built. 

You can use the tool to set up a secure password that allows printer storage encryption, remove user IDs and ex-employee access, delete documents from the print queue once they’re printed, and much more.

Tip #8. Educate Your Employees

If you work in an office, chances are you aren’t the only person using the printer. Everyone that has access to it needs to be aware of the responsibilities that come with its usage. Make sure to talk to your employees about ways to ensure both the physical and virtual safety of the printers. 

Your staff should also be careful when using their mobile devices to print, as smartphones are easier to hack. Explain to them what phishing scams are and how they can avoid being the victim. 

Finally, make sure it’s clear to them how they can use confidential information in your company.

It’s Time to Ensure Printer Security

Printers are the most overlooked devices when it comes to security. Given how most business owners consider them as merely internal devices whose sole function is to print documents, it’s no wonder they are a weak spot security-wise. 

Whether you use printers in your office or at home, take a moment to see how you can enhance its security before your next printing job.

As cybercriminals are a growing concern, each of us is responsible for protecting our data. Luckily, the tips from this article will help you bring your printer’s security to another level.
