The Importance of Multi-Factor Authentication (MFA)

20 June, 2024, by Madison Shaw

As organisations worldwide face an escalating number of cybersecurity threats, securing access to digital resources has never been more crucial - particularly in identity and access management (IAM). One key component of IAM that has emerged as a foundational layer of security is Multi-Factor Authentication (MFA). MFA can be implemented using several different methods, from one-time passcodes (OTPs) to biometric authentication, and as such is an easy and flexible way to significantly reduce the risk of unauthorised access.

Why MFA Matters

Each year, Verizon release their Data Breach Investigations Report, analysing security incidents and breaches in various industries worldwide. The 2019 version of this report highlighted that a significant number of data breaches were a result of stolen or misused passwords, meaning that these breaches could have been prevented entirely through the use of MFA; by implementing an additional authentication step, organisations can block access from attackers even if they have obtained compromised credentials.

Choosing the Right MFA Methods

Selecting the appropriate MFA method is crucial to balancing security with user convenience. Here are some common options:

• One-Time Passcodes (OTPs): Sends a single-use passcode to the user's mobile device or email. While convenient, they are susceptible to interception by cybercriminals.
• Authenticator Apps: These generate time-based OTPs. Apps from companies like Google and Microsoft provide a more secure alternative to SMS or email.
• Hardware Tokens: Physical devices that generate a passcode at the push of a button, offering high security without reliance on a user's personal device.
• Biometric Verification: Uses unique biological traits like fingerprints or facial recognition. This method is highly secure and user-friendly but requires appropriate hardware.

Implementing MFA in Your Organisation

To ensure user compliance and minimise resistance, it's important to choose MFA methods that align with the technical comfort and accessibility of different user groups. Education and clear communication about the benefits and operation of MFA can further ease the transition.

The rollout of MFA should be strategic and phased:

• Assessment: Evaluate the current security posture and identify the systems where MFA will have the most significant impact.
• Pilot Programme: Begin with a subset of users or critical applications to gauge the effectiveness and gather user feedback.
• Full Rollout: Expand the implementation across all users and systems, continually adapting based on feedback and evolving security needs.
• Continuous Review: Regularly review the MFA setup to adapt to new security challenges and technological advances.
