A secure security system is built on user permissions as well as two-factor authentication. They lower the risk that malicious insiders will act and have a lesser impact on data breaches and help to comply with regulatory requirements.
Two-factor authentication (2FA) requires the user to supply credentials from several 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 even something they are (fingerprints or a retinal scan). Passwords alone no longer offer sufficient protection against various hacking techniques — they are easily 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 accounts that are highly sensitive like tax filing and online banking websites as well as social media, emails and cloud storage, 2FA is crucial. Many of these services are accessible without 2FA. However making it available on the most crucial and sensitive accounts adds an extra layer of security.
To ensure that 2FA is working cybersecurity professionals should regularly evaluate their strategies to take into account new threats. This can also improve the user experience. This includes phishing attacks that fool users into sharing 2FA codes or «push-bombing» that overwhelms users by submitting multiple authentication requests. This leads to them approving legitimate passwords due to MFA fatigue. These issues, as well as many others, require an constantly evolving security solution that gives the ability to monitor user log-ins and detect suspicious activity in real-time.
