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. 

If you need more insight into protecting the security of your printers, get in touch with us today. We can set up a 10-15-minute chat to discuss how you can implement these changes and keep cybercriminals away.

Making the most of your Microsoft 365 apps requires you to adopt appropriate security measures.

Microsoft 365 is one of the best collaboration and productivity tools around. It provides users with seamless communication, scalability and supports remote work with various features. The security is also solid due to a wide array of defense mechanisms. 

But this doesn’t mean you’re impervious to cyberattacks. 

Data leakage, unauthorized access, and malware can still jeopardize your system and offer ideal entry points for hackers. Should your business fall victim, the consequences can be dire, ranging from operational disruptions to severe reputational damage. 

The only way to fend off hackers is to take your Microsoft 365 data protection to the next level. And this article will list the 11 most effective security measures to help shield your data in Microsoft 365.

The 11 Effective Security Measures

Security Measure #1 – Activate Multi-Factor Authentication

Microsoft 365 users have just one method of verifying their identity when using a username and password. Unfortunately, many people don’t follow robust password protocols. If you’re doing the same, you’re exposing your organization to intrusions. 

That’s where multi-factor authentication (MFA) comes into play. 

It can boost your Microsoft 365 security with one-time passphrases or other factors to verify user identity. Best of all, this measure is easy to apply. 

However, enabling MFA should only be your first step. The next one is to activate Security Defaults, a Microsoft feature that enforces MFA in each administrator account. 

Another great idea is to implement MFA in all accounts without administrator permissions. It’s because these accounts can still endanger services and apps in your ecosystem. 

Security Measure #2 – Use Session Timeouts

Many employees fail to log out of their accounts and lock their mobile devices or computers. This can grant hackers unlimited access to enterprise accounts, enabling them to compromise your data. 

Incorporating session timeouts into internal networks and accounts automatically logs users out after a certain inactivity period. That means hackers can’t take over their devices and access sensitive information.

Security Measure #3 – Refrain From Public Calendar Sharing

Calendar sharing enables your employees to synchronize and share schedules with colleagues. While this facilitates team collaboration, it can also give hackers insight into your operations and vulnerable users. 

For example, if your security administrator is on vacation and this information is publicly available, attackers can use this window to launch malware. 

Security Measure #4 – Employ Advanced Threat Protection

Advanced threat protection (ATP) is a robust solution that recognizes and prevents advanced threats that usually bypass antivirus and firewall defenses. 

It grants access to a database that receives real-time updates, allowing users to understand the threats and integrate the data into their analysis. 

ATP notifies you about attacks, the severity, and the method that stopped them, regardless of the source. It’s especially effective at preventing phishing. 

It relies on machine learning and a massive database of suspicious sites notorious for malware delivery or phishing attempts. 

Security Measure #5 – Leverage Policy Alerts

Microsoft 365 lets you establish your policy notifications in the compliance center to meet your company’s security needs. For example, they send your employees tips on sending sensitive information whenever they’re about to send a message to a contact outside your network. 

These warnings can safeguard against data leaks while educating your team on safe data sharing methods. 

Security Measure #6 – Secure Your Mobile Access

Your team often uses smartphones to access work email, contacts, documents, and calendars, especially if they work remotely. So, securing their devices should be your top priority when protecting data. 

The best way to do so is to install Microsoft 365 mobile management features. They can let you manage your security policy, permissions, restrictions, and wipe crucial information from stolen or lost devices.

Security Measure #7 – Deactivate Legacy Protocol Authentication

It’s worth noting that legacy protocols don’t support several security features in Microsoft 365 that reduce the chances of intrusion, such as MFA. This can make them perfect gateways for adversaries who want to target your organization. 

That said, your best bet is to deactivate legacy protocols to mitigate risks. 

However, you may not want to disable legacy authentication if your team needs it for older email accounts. The good news is that you can still make your network safer by restricting access to users who don’t need this protocol. 

Security Measure #8 – Integrate Role-Based Access Control

Access management is a convenient security feature that can limit the flow of private information across your business. It allows you to establish the users who can access data in your company. 

For instance, you can minimize data leaks by preventing rank-and-file team members from reading and editing executive-level files.

Security Measure #9 – Rely on Unified Audit Log 

Unified audit log (UAL) includes logs from several Microsoft 365 services, such as Azure AD, SharePoint Online, OneDrive, and Microsoft Teams. Enabling it can give the administrator insight into malicious activity and actions that violate organizational policies. 

You may also want to incorporate your logs into an existing SIEM (Security Information and Event Management) tool. Doing so enables you to connect logs with current log monitoring and management solutions to reveal abnormal activity. Plus, it can improve the overall security of your Microsoft 365 suite. 

Security Measure #10 – Encrypt Emails

Encrypting sensitive data is often the last resort when dealing with data breaches. But if cyber attackers access your emails, robust encryption tools can make them unreadable. That’s why email encryption is something worth looking into.

This feature is essential for Microsoft 365 users who share emails and files regularly. 

Security Measure #11 – Train and Educate Your Employees

The above measures are undoubtedly effective, but they may amount to nothing if you leave your employees out of the picture. In fact, human error is the leading cause of most data breaches.

One of the best ways to prevent security breaches in your business is to schedule employee security training and education. It can raise their awareness of potential threats and guide them on how to address them. 

This is especially important when recruiting employees. Make sure they undergo in-depth security training before granting them access to sensitive data and organizational devices. 

Don’t Leave Your Business’s Data Protection to Chance 

Microsoft 365 offers a bunch of intuitive and convenient tools. The experience can be so smooth that you may even forget about protecting your data. 

However, you’re taking a huge gamble in doing so, as it leaves your system open for hackers. 

With that in mind, applying the defense mechanisms mentioned in this article will dramatically decrease security threats to your business.
