Continuous Authentication: The Future of Security

Usernames and passwords act as a gateway to access a device. Inserting another authentication step on top of these credentials will make it harder for hackers to infiltrate. However, traditional authentication processes are not enough to provide robust security throughout a user work session. That’s where continuous authentication plays a crucial role in securing organizations’ sensitive data. In this article at infosecurity magazine, Sid Potbhare explains why organizations need continuous authentication and its benefits.

What is Continuous Authentication?

This continuous authentication is a combination of several authentication schemes to provide the best workflow for the end-users and the highest security level. It is a mechanism that regularly validates a user’s authenticity after the user has logged in for the session’s entire duration. “Continuous authentication targets the biggest risk factor in computer security – the people leaving the workstation unlocked and unattended,” explains Sid.

Types of Continuous Authentication

Presence-based authentication: Here, the computer continually scans the users’ presence through a wireless radio signal. When the employee leaves the computer’s vicinity, the machine locks automatically, thereby preventing any unauthorized access.

Biometric authentication: Facial recognition devices ensure the verified user is still present and lock the session when they move away. With modern video matching algorithms, biometric authentication can achieve high accuracy.

Behavior-based authentication: This can include using mouse movement, typing, or website activity to determine the employee’s presence. By building a user’s behavioral signature, authentication software will undoubtedly prevent access whenever real-time use of the computer starts deviating from the employee’s behavioral model.

How Is It Beneficial?

One of the benefits of continuous authentication from the users’ standpoint is that it doesn’t require employees to do anything extra to authenticate themselves during a session. The technology does validation automatically while the employees work. Besides, it provides high levels of security for organizations that are not feasible with current access systems.
