How multifactor authentication strengthens network security

With newsfeeds being filled with headlines about data breaches, hacked networks and encrypted data held at ransom, its little wonder businesses are seeking ways to better secure their networks — and rightly so.

Businesses large and small are actively seeking ways to be more secure. 
The implementation of better password practices, document shredding policies, network user education, new back up and disaster recovery systems and multifactor authentication (or MFA), just to name a few. In this article, we are going to look at MFA.

Why multifactor authentication?

While passwords are great at limiting network access and providing some security, these days they are too easily thwarted. That’s why there is multifactor authentication — to make sure that though in the wrong hands, a password will not allow unauthorized network access.

What is multifactor authentication?

MFA works by requiring users logging into a network/application/system to not only provide a password, but to provide additional verification through another medium (text, phone call or a mobile app … etc.).

Let’s look at an example of MFA. In this example, we will be using a mobile device as the secondary level of user verification. After a user enters a valid password, they are prompted to enter a code from an application or text message delivered to the mobile device they set up when they initially created their account. Only after the valid code is entered will the user gain access to the system they are attempting to log into. Please note: There are other ways, a phone call for example, by which this secondary authentication can be accomplished. However, the most common seems to be through a mobile app/text. 

The key to understanding MFA, as you can see from the above example, is in the M (multi) in MFA. By requiring multiple levels of authentication, we are creating a new level of complexity to keep out those bad actors/hackers and ensure the safety of our internal systems and data.

While the above example is a case of two-factor authentication, using a password and a mobile device as two separate factors, other factors can be added, such as PINs or personal facts only known to you, the presence of a key fob or an access card, or the use of your fingerprint, retinal pattern, voice and so on.


Any of these factors in conjunction with a password ensure far more network security than just a password. That’s why MFA is increasingly common as a cybersecurity measure.
