Two-Factor Authentication (2FA)

Providing an additional layer of protection for your network.

2FA ensures only trusted users have access to your network and data.

What Is Two-Factor Authentication (2FA)?

Two-factor authentication (2FA) is becoming increasingly prevalent in today’s business environment. One of our preferred 2FA/MFA vendors is Duo. With cybercriminals gaining access to networks and data by merely guessing commonly used user passwords, 2FA incorporates an additional layer of protection into your existing security strategies to ensure users really are who they say they are.

2FA works by requiring users to enter an additional code upon login to verify their identities. When a user tries to log in, a unique code is sent to their email address or their mobile device. They are then prompted to enter that code before being granted login access. Because the unique code changes every time a user attempts to log in, it becomes virtually impossible for a hacker to gain access, even if they know the user’s password.

As with any network security platform, 2FA is not foolproof. If a cybercriminal has access to a user’s cell phone or email account, they may be able to circumvent 2FA security by intercepting the authentication code. However, users will be alerted of the attempted login and may be able to flag the account before network data are compromised.

Ensure users really are who they say they are.

2FA confirms a user’s identity before granting network access.

Two-Factor Authentication Platforms

History has shown that passwords aren’t always enough. Cybercriminals can guess commonly used passwords, find passwords that have been written down or shared, or deploy brute force attacks that use a script to enter all possible password combinations. 2FA works to mitigate these threats by adding an additional layer of identity verification. The most common platforms for deploying a 2FA solution include:

Verification Codes

As mentioned above, when a user attempts to log in to your network, they are prompted to enter the unique code that’s sent to their email address or mobile device. Upon entering the correct code, the user is granted network access. The user may also have the option to label the device they’re using as trusted, so they won’t have to repeat the process every time they log in on that device. However, if logging in on a new, unrecognized device, they will be prompted to re-verify their identity. That means anytime a cybercriminal attempts to log in, they would also have to have email or cell phone access to infiltrate your network.

Authenticator Apps

Authenticator applications work similarly to verification codes. Users download an authentication application to the mobile device of their choice and link their accounts to the application. Whenever they attempt to log in, they will be prompted of an attempted login, the location of the attempted login, and given a code to verify that they are an authorized user. An authenticator app also allows for multiple accounts to be synced on one device, making it easier for your team to verify logins if they depend on multiple network platforms for day-to-day operations.
