Tips to Maximise the Effectiveness of MFA Implementation
30 March 2023

In today’s digital world, authentication is the new entry point into our networks, and it’s critical to ensure maximum security. With the rise of cyberattacks, simply changing passwords periodically and implementing two-factor authentication (2FA) is no longer enough. Attackers can use approval fatigue to bypass 2FA prompts and gain access to cloud resources by using the user’s credentials. Therefore, it’s essential to implement effective multifactor authentication (MFA) strategies to safeguard your network and cloud resources.

In this blog, we’ll discuss various tips to enhance your MFA implementation and maximize its effectiveness.

Evaluate and Adjust Your MFA Implementation:

If you have an MFA implementation in place, it’s time to evaluate and see if it needs further adjustments. Microsoft is updating its recommendations for 2FA and introducing a new number-matching methodology in February 2023. Therefore, it’s better to test and implement these changes now.

Avoid MFA Implementation Fatigue:

Attackers use MFA notification fatigue to trick users into approving false prompts. To avoid this, we recommend setting up groups and enforcing 2FA across your network. We also suggest adding a geographic location to the MFA prompt to indicate where it’s coming from, as it raises awareness and prevents spamming attacks. The Cybersecurity and Infrastructure Security Agency (CISA) recommends implementing phishing-resistant MFA techniques such as FIDO/WebAuthn authentication and Public Key Infrastructure (PKI)-based MFA that includes physical tokens like YubiKey.

Prioritize Deployments:

It’s critical to prioritize the deployment of MFA to roles and cloud applications that need the most protection. Review your risk analysis and identify the most at-risk assets.

Use Number Matching:

CISA provides a white paper on using number matching-based MFA authentication to enhance your cloud application’s protection. Several vendors, including Duo verified push and Okta TOTP, are implementing these additional protection methodologies.

Review Audit Logs:

It’s essential to review audit logs regularly and encourage staff to report any unusual MFA prompts they receive. Forensic staff can then review logs and investigate the failed MFA authentication.

Update Defaults on Azure Active Directory:

If you’re using Azure Active Directory, we recommend updating the default settings on MFA implementation to “enabled.” This way, you can choose specific groups where number matching will be enabled. Leaving the timing to Microsoft can cause confusion among your end-users and may lead to more friction and frustration.

In conclusion, it’s critical to implement effective MFA strategies to safeguard your network and cloud resources. By following these tips, you can maximize the effectiveness of your MFA implementation and prevent cyberattacks. Remember to prioritize deployment to key roles and cloud needs to ensure that the most at-risk assets are protected.
