User permissions and two-factor authentication are a critical component of a robust security system. They decrease the risk of malicious insider activities as well as limit the effects of data breaches and help comply with regulatory requirements.
Two-factor authentication (2FA) requires the user to provide credentials from a variety of categories – something they know (passwords PIN codes, passwords and security questions) or have (a one-time verification code sent to their phone or authenticator app), or something they are (fingerprints or a retinal scan). Passwords alone no longer offer adequate protection against methods of hacking — they can easily be stolen, given to the wrong people, and are easier to compromise via phishing and other attacks such as on-path attacks and brute force attacks.
For sensitive accounts like tax filing and online banking websites as well as social media, emails and cloud storage, 2FA is essential. A lot of these services are accessible without 2FA, but making it available for the most sensitive and critical ones adds an extra layer of security that is hard to break.
To ensure the effectiveness of 2FA security professionals must to reevaluate their authentication strategy regularly to account for new threats and improve user experience. These include phishing attempts that trick users into sharing 2FA codes, or “push-bombing” that annoys users by sending multiple authentication requests. This results in being unable to approve legitimate logins because of MFA fatigue. These challenges, and many others, require an evolving security solution which provides visibility into user log-ins to identify anomalies real-time.
