MFA, Multi-Factor Authentication

Multi-factor authentication (MFA) is a multi-layered method of securing virtual and physical access, where the system requires the user to provide a combination of two or more authenticators to verify their identity when logging in. MFA enhances security because unauthorized users will not be able to gain access to the target even if one authenticator is compromised.

DESCRIPTION

How the MFA Works?

To gain access, users must provide at least two authentication factors at login to verify their identity. Each new element of authentication that is added to the login process increases security. In most cases, to use multi-factor authentication (MFA), a user must enter some combination of the following:

  • Something you know: for example, a password or personal identification number (PIN);
  • Something you have: for example, a smart card, mobile token or hardware token; and
  • A certain biometric factor (for example, fingerprints, palm or voice recognition).

For example, MFA may require customers to insert a smart card or bank card into a card reader and then enter a password or PIN. If the person holding the card does not know the password, they will not be able to log in. Similarly, without physical access to the card, the password is meaningless.

What Differs MFA From 2FA?

Multi-factor authentication (MFA) and two-factor authentication (2FA) use additional forms of authentication to protect your account. Any two-factor authentication is always MFA, but multi-factor authentication is not always 2FA. Multi-factor authentication (MFA) requires two or more authentication factors to be provided, while 2FA requires two to be provided. In today’s threat environment, 2FA and MFA are essential because a single password is no longer enough to protect against cyberattacks.

Below is an example of using 2FA:

  • The user tries to register in the online service using his username and password.
  • The system provides a second authentication factor, confirming the accuracy of the credentials.
  • The user generates a security code using the Google Authenticator app (possession factor) on their mobile phone.
  • On the login page, the user enters a code to access their account.

Is using MFA more secure than 2FA?

Because 2FA and MFA rely on more than just a password, they are much more secure than single-factor authentication (SFA). Multi-factor authentication (MFA) is generally considered more secure than 2FA because it offers the highest level of protection against cybercriminals. However, the reliability of a Multi-Factor Authentication (MFA) solution depends on the security of its additional authentication methods.
Codes sent by email and SMS are not as secure as other forms of authentication.The presence of phishing attacks on both platforms and the ability to compromise SIM cards increase cybersecurity risks. MFA works best when it relies on biometric authentication elements that are unique to each user and difficult to replicate.

The Intelligent IT Distribution company is a distributor of solutions from the world’s leading software manufacturers, so it will be able to offer a wide range of MFA solutions that will perfectly suit the needs of customers.

Why are 2FA and MFA important?

Most financial, healthcare, educational and government institutions offer their customers the ability to create accounts online. Personally Identifiable Information (PII), Protected Health Information (PHI) and other sensitive data are stored by these service providers. Previously, accounts were protected using Single Factor Authentication (SFA), which only required entering a password. Today, this is no longer enough.

Cybercriminals in today’s threat landscape specialize in gaining unauthorized access to sensitive data, especially through SFA logins. Hackers can obtain passwords and use users’ personal information for malicious purposes through a variety of strategies. The most common methods for obtaining passwords are:

  • Brute Force Attacks: In this type of cyberattack, a hacker “guesses” a user’s password until he finds the right combination. When users have weak passwords, such as birth dates, this method has a high success rate.
  • Data Leaks: A user/service accidentally posts sensitive data online, which a hacker finds and uses to gain unauthorized access, such as a birth date on LinkedIn. Despite serious security issues, many people still reuse the same passwords across multiple accounts. Attackers can use these compromised passwords across multiple accounts of the same user until they find a successful login combination.
  • Keyloggers: Hackers install this type of malware on unsuspecting users’ systems. Keyloggers record keystrokes and read clipboard data on compromised devices. This allows hackers to steal passwords and other information that could allow unauthorized access.
