Credential theft is now at an all-time high and is responsible for more data breaches than any other type of attack.

With data and business processes now largely cloud-based, a user’s password is the quickest and easiest way to conduct many different types of dangerous activities.

Being logged in as a user (especially if they have admin privileges) can allow a criminal to send out phishing emails from your company account to your staff and customers. The hacker can also infect your cloud data with ransomware and demand thousands of dollars to give it back.

How do you protect your online accounts, data, and business operations? One of the best ways is with multi-factor authentication (MFA).

It provides a significant barrier to cybercriminals even if they have a legitimate user credential to log in. This is because they most likely will not have access to the device that receives the MFA code required to complete the authentication process.

What Are the Three Main Methods of MFA?

When you implement multi-factor authentication at your business, it’s important to compare the three main methods of MFA and not just assume all methods are the same. There are key differences that make some more secure than others and some more convenient.

Let’s take a look at what these three methods are:

SMS-based

The form of MFA that people are most familiar with is SMS-based. This one uses text messaging to authenticate the user.

The user will typically enter their mobile number when setting up MFA. Then, whenever they log into their account, they will receive a text message with a time-sensitive code that must be entered.

On-device Prompt in an App

Another type of multi-factor authentication will use a special app to push through the code. The user still generates the MFA code at login, but rather than receiving the code via SMS, it’s received through the app.

This is usually done via a push notification, and it can be used with a mobile app or desktop app in many cases.

Security Key

The third key method of MFA involves using a separate security key that you can insert into a PC or mobile device to authenticate the login. The key itself is purchased at the time the MFA solution is set up and will be the thing that receives the authentication code and implements it automatically.

The MFA security key is typically smaller than a traditional thumb drive and must be carried by the user to authenticate when they log into a system.

Now, let’s look at the differences between these three methods.

Most Convenient Form of MFA?

Users can often feel that MFA is slowing them down. This can be worse if they need to learn a new app or try to remember a tiny security key (what if they lose that key?).

This user inconvenience can cause companies to leave their cloud accounts less protected by not using multi-factor authentication.

If you face user pushback and are looking for the most convenient form of MFA, it would be the SMS-based MFA.

Most people are already used to getting text messages on their phones so there is no new interface to learn and no app to install.

Most Secure Form of MFA?

If your company handles sensitive data in a cloud platform, such as your online accounting solution, then it may be in your best interest to go for security.

The most secure form of MFA is the security key.

The security key, being a separate device altogether, won’t leave your accounts unprotected in the event of a mobile phone being lost or stolen. Both the SMS-based and app-based versions would leave your accounts at risk in this scenario.

The SMS-based is actually the least secure because there is malware out there now that can clone a SIM card, which would allow a hacker to get those MFA text messages.

A Google study looked at the effectiveness of these three methods of MFA at blocking three different types of attacks. The security key was the most secure overall.

Percentage of attacks blocked:

SMS-based: between 76 – 100%
On-device app prompt: between 90 – 100%
Security key: 100% for all three attack types

What’s in Between?

So, where does the app with an on-device prompt fit in? Right in between the other two MFA methods.

Using an MFA application that delivers the code via push notification is more secure than the SMS-based MFA. It’s also more convenient than needing to carry around a separate security key that could quickly become lost or misplaced.

Looking for Help Setting Up MFA at Your Company?

Multi-factor authentication is a “must-have” solution in today’s threat climate. Let’s discuss your barrier points and come up with a solution together to keep your cloud environment better secured.

Smartphones and tablets are often the preferred device for communications, web searching, and accessing many types of apps. They’re more portable and can be used from anywhere.

We’re seeing the takeover of many activities that used to be performed on traditional computers. Now, people are using mobile devices instead.

For example, Microsoft estimates that up to 80% of the workload in many enterprise organizations is now done via mobile devices. Over half of all web searches are also now conducted from a mobile device rather than a desktop PC.

This has caused mobile devices to become more targeted over the past few years. As hackers realize they’re holding many of the same sensitive information and app access as PCs, they’ve been creating mobile malware and other exploits to breach mobile devices.

In 2020, approximately 36.5% of organizations were impacted by mobile malware and 2.5 million people unknowingly downloaded multiple mobile adware apps.

It’s important to start treating mobile devices in the same way as you do computers when it comes to their security. Smartphones and tablets need the same types of security precautions in place, including:

Antivirus/anti-malware
DNS filtering
Automated OS and app updates
Managed backup

You need to be on the lookout for the most prevalent mobile device threats that allow your data to be leaked or breached. Here’s a roundup of what those are.

1. Mobile Malware Hidden in Apps

It’s not easy at first glance to tell the difference between a legitimate free app and one that has malware hidden inside.

Scammers will use the same types of flashy graphics, and the app may even have a high star rating (most likely boosted through suspicious means). The app may even do what it says it will do when downloaded.

But malware can be hidden in the background, infecting a device as soon as the app is installed. And many of these apps will hide once on your phone or tablet by using the icon of a common default system app (like settings or calendar).

Mobile malware can include all the same types of malware that can infect a computer, such as ransomware, adware, spyware, trojans, and more.

2. Unprotected Communications

Have you ever sent someone a password or credit card details over a text message or messaging app? Did you check to see if the communication was encrypted?

Many users will use various methods of communication from their mobile devices without knowing how secure those methods are. If sensitive information is transmitted and it’s not encrypted, then a hacker could easily intercept it.

3. Public Wi-Fi & Man-in-the-Middle Attacks

Public Wi-Fi has long been known to be non-secure, yet people still use it when it’s available. They want to save their mobile minutes or get a faster connection.

75% of people admit to connecting to email when on public Wi-Fi. Other activities people will do is sign into apps (even sensitive ones like online banking), and shop online, entering credit card details.

If you’re on public Wi-Fi, then you’re at high risk of a man-in-the-middle attack. This is when a hacker connects to the same network and looks for victims with unprotected communications. They can then capture any type of data they’re transmitting.

One way to safely connect to public Wi-Fi is to use a VPN app, which will encrypt your communications.

4. Juice Jacking on Public USB Charging Stations

Another public mobile breach danger is public USB charging stations. These are often welcome sights especially if you’re low on battery power. However, hackers can infect public USB charging ports with malware and set up fake charging stations in public areas.

Then, when you insert your USB cord to charge your device, the malware is copying all the data on your phone and/or infecting it with malicious code. See, USB cables aren’t just for charging, they are also used for data transmission.

It’s best to avoid public USB charging ports and charge with your power adapter that plugs into an outlet instead. You can also buy a “charge-only” USB cord to use if USB charging is your only option.

5. Non-Updated Devices

Approximately 40% of Android devices are running outdated operating systems that no longer get vital security updates.

When your mobile device is not kept updated, then it’s easier for a hacker to use an exploit that takes advantage of a code vulnerability in the OS or one of the installed apps.

Many companies aren’t paying attention to how many employees’ work devices are running current operating systems, which puts their networks at higher risk of a breach.

You should ensure that all your apps and your OS are kept updated because many of these updates include critical security patches.
