User permissions and two-factor authentication are essential components of a secure security infrastructure. They can reduce the risk of malicious or accidental insider threats, limit the impact of data breaches, and ensure regulatory compliance.
Two-factor authentication (2FA) requires users to input credentials from two different categories to sign into an account. It could be something the user knows (password, PIN code, security question) or something they already have (one-time verification code sent to their phone or an authenticator app) or something they have (fingerprint or face, retinal scan).
Most often, 2FA is a subset of Multi-Factor Authentication (MFA) which is comprised of more than two. MFA is a requirement in certain industries like healthcare banking, ecommerce, and healthcare (due to HIPAA regulations). The COVID-19 epidemic has brought new urgency to security for businesses that require two-factor authentication for remote workers.
Enterprises are living organisms and their security infrastructures are always evolving. New access points are created each day, roles change, hardware capabilities develop and complex systems reach the hands of users every day. It is crucial to regularly reevaluate the two-factor authentication strategies at regular intervals to ensure they keep up with the latest developments. One method to do this is to utilize adaptive authentication. It is a type of contextual authentication that will trigger policies based on how it is used, when and when a login request comes in. Duo provides a central administrator dashboard which allows you to easily monitor and set these types of policies.
