User Permissions and Two Factor Authentication
User permissions and two-factor authentication are essential components of a strong security infrastructure. They can reduce the chance that malicious insiders will take action to cause security breaches and help meet regulatory requirements.
Two-factor authentication (2FA) requires the user to provide credentials from a variety of categories – something they are familiar with (passwords, PIN codes and security questions) or something they have (a one-time verification code sent to their phone or authenticator app), or something they’re (fingerprints or a retinal scan). Passwords aren’t sufficient protection against various hacking techniques — they are easily stolen, shared with wrong people, and are more vulnerable to compromise through frauds such as on-path attacks or brute force attacks.
For accounts that are sensitive, such as tax filing and online banking websites as well as social media, emails and cloud storage, 2FA is essential. Many of these services can be used without 2FA. However making it available on the most sensitive and crucial ones adds an extra layer of security.
To ensure that 2FA is working, cybersecurity professionals must regularly revisit their strategy to keep up with new threats. This can also improve the user experience. This includes phishing attacks that trick users into sharing 2FA codes, or “push-bombing” that annoys users by sending multiple authentication requests. This can lead to them approving legitimate passwords because of MFA fatigue. These issues, as well as many others, require an evolving security solution that gives visibility into user log-ins to detect suspicious activity in real-time.
