If you are running a small business, you want to make it harder for cybercriminals to break into your systems and steal data. But stopping them? That’s not always easy. Multi-factor authentication helps to place a larger barrier between you and criminals, so you can shut down their attempts to access your data.
The Importance of Multi-Factor Authentication
Have you ever been prompted to enter letters, numbers, and symbols when creating a new password? For a long time, these combinations were enough to keep cyber thieves out of your systems. But not anymore. Criminals are sneaky, and cracking “hard” passwords is now easier.
MFA challenges your employees to prove who they are before accessing your systems. MFA requires a second and maybe even a third test for users to help keep criminals out. And these tests are critical, since over half of security breaches are directly traced back to stolen credentials.4
Cybercriminals want an easy target, and using MFA helps ensure that your business isn’t that target.
Two-Factor Authentication (2FA) vs. Multi-Factor Authentication (MFA)
Unsure of the difference between 2FA and MFA? At first glance, they look similar. 2FA requires exactly two forms of authentication, such as your login credentials and a code sent to your cell phone. MFA also requires at least two factors, but it sometimes requires more.
So, is MFA better than 2FA? That’s a great question. With every additional layer of security, you’re keeping hackers a step further away from your data. For example, if 2FA requires you to enter your login credentials and a code sent to your email address, but MFA requires these two factors plus your fingerprint, MFA is putting a larger buffer between you and criminals.
Benefits of Multi-Factor Authentication
You’ve used passwords for years to keep criminals away from your data, but today’s passwords provide little protection against risk. Stealing passwords may be easy for hackers, and once they have those passwords in hand, breaking into your systems is a simple task.
The benefit of MFA is that it helps to provide your business, employees, and customers with better security. People who know that you use MFA understand that you take security seriously. And you’re at far less risk for the brute-force attacks that make headlines.
How Does MFA Work?
MFA requires up to three different authentication factors to verify your identity. The first is often your username and password. The second is usually a code sent to your email or smartphone. And the last is the hardest – such as a fingerprint or facial scan.
Stealing your username and password? That’s easy for hackers. But passing the other two tests is much more difficult, which helps to keep fraudsters locked out.
Types of Authentication
MFA uses a few different categories to make sure that anyone who logs in to your system has legit access. This includes something your employee knows (knowledge), something they have (possession), and something they are (inherence). Let’s break it down.
When you successfully enter your username and password, you’ve passed the first factor: knowledge. Another example of knowledge-based criteria is correctly answering personal security questions, such as “What was your first dog’s name?” or “What is the name of your birth city?”
You correctly entered your login credentials, so you passed the first test. Now MFA gives you a new test: You must enter a code sent to your cell phone. Alternatively, it might send that code to your email address.
If you meet the first two criteria, it’s unlikely that you’re a hacker. But MFA is diligent, and it wants to be certain. So, it checks something personal it can recognize, such as your fingerprint, retina, face, or voice.
MFA for Cloud Computing
There are two different ways that MFA technology can be deployed. It can be on premises (physically at your company), or it can operate in the cloud.
The benefit of cloud MFA is that it’s more cost effective than on-premises options. You don’t need to buy expensive equipment to get it up and running, and it’s easy to scale as your business grows. With so many employees working remotely, cloud MFA comes with fewer administration and hardware costs compared to on-premise options.
Also, hackers are constantly designing new threats to attack your business. Cloud MFA helps you stay up to date on these threats without the internal resources that on-premises options require.
