Making Your VoIP Network Bulletproof (Six Tips to Protect Your VoIP from Cyberattacks)

Chris Provencher on April 25, 2022

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.

The Critical Importance of Virtualized Infrastructure Security (And 4 Ways to Enhance It)

Chris Provencher on April 20, 2022

A torn-down virtual infrastructure creates risks for any business. And it can have a significant impact on how quickly you can retrieve your data and resume operations following an attack.

These days, many businesses use virtualized infrastructure for more straightforward data storage. It’s because this approach is superior to physical solutions due to enhanced flexibility, straightforward provisioning, and affordable pricing. 

However, this model also requires a comprehensive approach to security. 

There’s a much greater risk of data loss, as many tools and practices for physical data protection are nearly useless in the virtual setting. Virtual threats are different, that’s why you need to think beyond traditional perimeter protection. 

So, if you’re using a virtualized infrastructure for data storage, keep reading. 

This article discusses the risks of improper virtualized infrastructure security and talks about ways you can improve it. 

Don’t Leave Your Virtualized Infrastructure to Chance

Virtualization security is crucial for every business’s security strategy. After all, we now live in a world of virtualized environments and need to apply security to all its layers. 

Let’s explore three of the most common virtualization security issues. 

Issue #1. External Attacks

These are a real threat to virtualized infrastructure. 

If hackers enter your host-level or server management software, they can easily access other crucial parts of your system. They can create a new user, assign admin rights, and then use that power to extract or destroy your company’s sensitive data. 

Issue #2. File Sharing and Copy-Pasting

Host and virtual machine (VM) sharing is normally disabled. The same goes for copy-pasting elements between the remote management console and the VM. You can tweak the default settings by tweaking the ESXi host system, but this action isn’t recommended. 

Why?

Because if a hacker gains access to your management console, they’d be able to copy data outside your virtual environment or install malware into your virtual machine. 

Issue #3. Viruses

Virtual machines, or VM, are prone to many attacks, with ransomware being among the most popular ones. For this reason, it’s crucial to keep regular backups of your website data and store them off-site at a place where they can’t be encrypted by hackers. 

If you fail to perform backups, you may find yourself in a situation where hackers could ask you for money to decipher your data. 

Restoring a VM is quite tricky even if you perform regular backups. Therefore, you need to educate your team members on alleviating the risk of getting ransomware and other viruses. 

Optimizing Your Virtualized Infrastructure Security

Now that you’re aware of the 3 common issues a business can face if they have an unprotected virtual infrastructure, here are 4 tips on bolstering its security.

Tip #1. Managing Virtual Sprawl 

Virtual sprawls are often associated with growing virtual environments. The concept simply means that the more you expand, the bigger the need to keep your VMs secure. However, the number of machines can outgrow your ability to do so. 

To manage your virtual sprawl, consider doing the following:

  • Create an inventory of all your machines at all times
  • Set up lookouts featuring multi-location monitoring
  • Monitor IP addresses that have access to your VMs
  • Look for table locks
  • Don’t use database grant statements to give privileges to other users
  • Keep both on- and off-site backups
  • Assess your virtual environment regularly and determine which machines you need and which ones aren’t necessary
  • Have a central log of your systems and log all hardware actions
  • Create a patch maintenance schedule for all machines to keep them up to date

Tip #2. Focusing on Virtual Configuration Setup

If you use virtual servers, you risk major configuration defects. 

That’s why it’s essential to make sure initial setups are free from security risks. This includes unnecessary ports, useless services, and similar vulnerabilities. Otherwise, all your virtual machines will inherit the same problems. 

The truth is that many businesses have poor virtual network configurations. You can avoid being one of those by ensuring all virtual applications that call the host (and vice versa) have proper segmentation. This includes databases and all web services. 

It’s also worth mentioning that most virtualization platforms only offer three switch security settings: forged transmits, MAC address changes, and promiscuous mode. There’s no protection for virtual systems that connect to other network areas. 

So, make sure to investigate each virtualization platform that allows this kind of communication, including all memory leaks, copy-paste functions, and device drivers. You can also tweak the system monitoring assets to look out for these pathways. 

Tip #3. Securing All Parts of the Infrastructure

It’s imperative that you properly secure all of your infrastructure’s parts. This includes its physical components (switches, hosts, physical storage, routers) and virtual and guest systems. Don’t forget about all your cloud systems as well. 

When it comes to protecting different infrastructure parts, here are some things you can do:

  • Install the latest firmware for your hosts. Virtualized infrastructure needs to have the latest security patches. So, keep all your VMware tools updated. 
  • Your active network elements such as routers, switches, and load balancers should use the latest firmware.
  • Patch all operating systems with automatic updates. Schedule patch installations outside of your work hours and include automatic reboots. 
  • All virtualized environments should have reliable anti-malware and antivirus software installed (and regularly updated). 

Tip #4. Having a Robust Backup Plan

Proper disaster recovery (DR) and backup plans are crucial in ensuring your business can continue operating after an attack. It’s because both your physical and virtual components can equally suffer from damage done by hacker attacks, hurricanes, etc. 

Ideally, you want to have a DR site located at a faraway data center or in the cloud. This way, you’ll alleviate the risk of being shut for a long time if your vital data gets compromised. 

Also, make sure to back up your VMs and your physical servers. Fortunately, you can back up your physical systems that operate on Windows or Linux, as well as your VMs that run on any OS. 

Additionally, you want to make at least three copies of your data and store two of them in different virtual places. And make sure to keep one backup off-site. 

If you want to take things to another level, you can replicate your VMs to a different data center for emergencies. 

Prioritize the Security of Your Virtual Infrastructure

If you never gave much importance to virtualized infrastructure security, doing so should be your priority now. Given the number of possible threats, protecting your VMs from unauthorized data sharing, viruses, and other types of attacks is crucial. 

All aspects of your physical and virtual components need to be protected to avoid issues. If this topic is all Greek to you, you’re not alone. The reality is that many business owners have struggled with the same problem. 

However, you can reach out to us for a 10-15-minute chat where we can discuss how you can bring the security of your virtualized infrastructure to the next level.

OneNote is not just a powerful tool for note-taking. It’s also a useful tool that allows you to perform various functions for easy information processing. 

Some of its main benefits include:

Benefit #1. Promoting Real-Time Collaboration

OneNote is part of Microsoft’s fully-cloud based Office 365 suite. This means OneNote users can share files with other team members or clients in real-time. Multiple people can view and edit their notes simultaneously, allowing for a seamless collaboration anytime. 

A great thing about real-time editing is that you can track all changes to the file. You can even restore the previous version of a document in case of accidents.

Businesses that run in multiple locations can benefit from this feature as well. It’s because people located across the country can work on the same project without affecting team collaboration. 

Simply put, there’s no need to trade emails and waste time waiting for responses – managers can have an easy time collaborating with their team instantly without ever leaving the office. 

Benefit #2. Securing Sensitive Information

Doing business online and sharing sensitive data comes with security risks. This is especially true for notebook software. Fortunately, OneNote comes with a set of security features that protect your data from being exposed to third parties. 

For example, you can lock specific sections with passwords while having all your information secured with 3DES encryption at all times. And if your password-protected documents remain inactive for a long time, the software will automatically lock them to prevent data leaks. 

Benefit #3. Integration With Other Software

Like other Office 365 suite apps, OneNote has great integration abilities. You can sync your OneNote with Outlook to send email information directly to the app and vice versa. 

What’s more, you can integrate this software with non-Microsoft apps as well. Some notable plugins include Zapier, Slack, Trello, Evernote, Dropbox, Salesforce, and many others. And all your essential apps will be synchronized, allowing your team to be more productive each day. 

Benefit #4. Project Management

OneNote has dozens of uses for general business. However, it’s especially suitable for project management. 

Project managers often deal with issues such as team member misunderstandings, communication delays, or project bottlenecks. But thanks to Microsoft’s note-taking tool, many of these issues are quickly alleviated. 

Project management can become more straightforward. It’s because OneNote makes it easy for the manager to track each team member’s achievements. They can update timelines, check off completed tasks, or assign new ones with ease. 

Take OneNote to the Next Level 

If you have never used OneNote before, you may be interested to learn about some tips to help you get the most out of the software.

Tip #1. Creating Quick Notes

Quick Note is a great feature that lets you write down a thought when you’re out having lunch or away from the office. 

Imagine being in the store and remembering you haven’t responded to an important email. You can take your phone, open the One Note app, and create a Quick Note reminding you of this task. 

The next time you open OneNote on your computer, you’ll see the message there. 

This feature is similar to Sticky Notes, as it lets you jot down any idea or thought in a matter of seconds. All your notes will be saved in the “Unfiled Notes” section of your “Quick Notes” notebook, a place where all your notes are saved by default. 

Tip #2. Searching Across All Notes

Searching for notes becomes more challenging as time passes. If you’re an active user, you can find yourself storing hundreds of notes in a matter of months. But don’t worry, as there are tons of options to organize your notes as well as search for it. 

OneNote has a built-in search option to make note finding easier. 

All you need to do is click on the magnifying glass or hit “Ctrl” (or “Command” for Mac) + “F” on your keyboard and look for a phrase or word. The software will go over all your typed, handwritten, and even picture notes. 

You can further narrow the search by selecting the drop-down arrow and choosing the desired option. You’ll see all matching results highlighted in your notes. 

As you find the note you needed, you can close the search by pressing “X” on the right-hand corner. 

Tip #3. Using Pre-Made Templates

OneNote is designed to have a blank canvas for each new note. And it’s what gives users a whole lot of flexibility. However, you can find this approach to be too basic sometimes. So, why not add some style, structure, and color to the app?

Thankfully, there are tons of pre-made templates to choose from. You can download a template with decorative backgrounds, to-do lists, planners, and more. 

Note that you can use the templates only on new OneNote files. The ones that already contain text won’t work since most designs require content to appear in a specific place on the page. 

If you need to add a template to your existing note, simply create a new one, then copy the existing text over. 

Tip #4. Scanning Documents from Your Smartphone

Do you need to take notes from a scanned document? That’s not an issue for OneNote. You can use the Microsoft Lens: PDF Scanner App (available for Android and iOS) to take high-quality scans of multiple documents using your phone and upload them to OneNote. 

Become the Master of Note-Taking

Digital note-taking tools have helped thousands of workers and managers become more productive. OneNote is one such software that seems to have it all – abundant features, flexibility, and ease of use. 

Whether you’re a business owner who wants to boost your team’s performance or a project manager that needs better tracking of the project timeline, OneNote has something in store for everyone. 

If you’d like to learn more about how this powerful tool can help you make your business better, feel free to reach out to us. We can have a 10-15-minute chat about this topic.

Office 365 Hacking: What you need to know!

What is a Compromised Email Account in Microsoft 365?

Access to Microsoft 365 mailboxes, data and other services, is controlled by using credentials, for example a user name and password or PIN. When someone other than the intended user steals those credentials, the stolen credentials are considered to be compromised. With them the attacker can sign in as the original user and perform illicit actions.

Using the stolen credentials, the attacker can access the user’s Microsoft 365 mailbox, SharePoint folders, or files in the user’s OneDrive. One action commonly seen is the attacker sending emails as the original user to recipients both inside and outside of the organization. When the attacker emails data to external recipients, this is called data exfiltration.

 

How to secure and restore email function to a suspected compromised Microsoft 365 account and mailbox.

Even after you’ve regained access to your account, the attacker may have added back-door entries that enable the attacker to resume control of the account.

You must do all the following steps to regain access to your account the sooner the better to make sure that the hijacker doesn’t resume control your account. These steps help you remove any back-door entries that the hijacker may have added to your account. After you do these steps, we recommend that you run a virus scan to make sure that your computer isn’t compromised.

Step 1 Reset the user’s password

Step 2 Remove suspicious email forwarding addresses

Step 3 Disable any suspicious inbox rules

Step 4 Unblock the user from sending mail

Step 5 Optional: Block the user account from signing-in

Step 6 Optional: Remove the suspected compromised account from all administrative role groups

Step 7 Optional: Additional precautionary steps

 

Secure Microsoft 365 like a cybersecurity pro

Your Microsoft 365 subscription comes with a powerful set of security capabilities that you can use to protect your data and your users.
