A secure security system is built on user permissions and two-factor authentication. They can reduce the chance that malicious insiders will act to cause data breaches, and assist in helping meet regulatory requirements.

Two-factor authentication (2FA) requires the user to provide credentials from a variety of categories – something they know (passwords, PIN codes and security questions), something they own (a one-time verification code sent to their phone or authenticator app) or something they’re (fingerprints or a retinal scan). Passwords by themselves are not adequate protection against various hacking techniques – they are easily stolen, shared with incorrect people, and easier to compromise via attacks like phishing as well as on-path attacks or brute force attacks.

For sensitive accounts like tax filing and online banking websites and emails, social media and cloud storage, 2FA is vital. A lot of these services are available without 2FA, however making it available for the most sensitive and critical ones adds an extra security layer that is tough to get over.

To ensure that 2FA is effective security professionals need to regularly revisit their strategy to keep up with new threats. This will also enhance the user experience. These include phishing attempts that trick users into sharing 2FA codes, or “push-bombing” which frightens users by sending multiple authentication requests. This leads to users approving legitimate requests because of MFA fatigue. These challenges, as well as others, require an constantly evolving security solution that provides an overview of user log-ins in order to detect any anomalies important site in real time.
