PER USE CASE
Continuous authentication is a method for authenticating users and granting access to corporate resources. It’s based on the level of risk and contextual information about the user, such as role, location, and type of device.
Unlike traditional authentication methods, this mechanism is enforced from login through the end of the user session.

Continuous authentication works by assessing user behavior patterns on an ongoing basis. Unlike traditional authentication, which evaluates users just once at login, continuous authentication considers changing risk factors such as location, device posture, and other behavioral data.
Continuous authentication provides security for hybrid workforces by allowing authentication to the corporate network while restricting access if suspicious activity is detected.
Authentication methods can be categorized according to different factors. Here are some common authentication methods:

Continuous user authentication goes beyond traditional authentication methods to take security to the next level. Authentication scores are continuously assessed based on factors like device posture and location, which help indicate when suspicious activity or attempts at unauthorized access are taking place. If the authentication score doesn’t show a sufficient confidence level, the system requests another type of authentication. You can set different confidence scores according to the type of action or resource involved.
Adaptive authentication allows scanning of end user devices both before and throughout a user session to corporate applications. Based on location, device posture assessment, or user risk score, an admin can define how a user is authenticated and authorized to access their apps. With adaptive authentication, these risk factors are evaluated continuously so admins can enforce (and adapt) policies as needed.
Risk-based authentication uses AI to gain a real-time view of the context of any login. The solution responds to a user's request for access by analyzing factors such as the type of device, location, the network used, time of log-in, and the sensitivity of the requested resources to make a risk assessment for the user—a risk score. If the request doesn’t meet the requirement, the system will ask for more information. The additional information may include a temporary code, a security question, biometric data, or codes sent to a smartphone.
What are the use cases where organizations may need continuous authentication? Here are some potential areas continuous authentication can help address:
Attack vectors in hybrid and remote workforces: Hybrid and remote work environments have increased cybersecurity risks. Whether users bring their own BYOD devices or use work laptops, it can be challenging for IT departments to maintain the security of unmanaged devices. Poorly protected networks can allow attackers to access the system, causing data leaks and intrusions. Employees using unsecured or weak Wi-Fi networks can be infected by malware or botnets.
Continuous authentication solutions prevent unauthorized users from accessing the system by detecting access requests from non-secure networks or devices.
Insecure passwords for remote employees’ accounts: Allowing employees to choose passwords for work-related accounts may seem convenient, but it can also create vulnerabilities. Allowing employees to use inadequate passwords, recycled passwords, or passwords shared with coworkers is a risky practice common in organizations. With most data breaches leveraging compromised credentials, securing passwords is critical.
By analyzing the entire context surrounding the user access request—and not only validating the password—continuous authentication solutions provide a more secure alternative.
A good user experience increases productivity and improves workflows. However, when users need to log in again every time they switch applications, the result is often lowered productivity. With continuous authentication, employees can log in once and gain access to all their normal applications and resources. Behavioral continuous authentication not only discourages attackers, imposters, and bots, but it does so without affecting the user experience.
In several industries, such as finance, continuous authentication is used to prevent fraud. The system collects data from different components of a customer’s session or interaction with mobile devices, such as swipe patterns or keystrokes. This information is used to develop a user profile. When the system finds a deviation from this pattern, it alerts or requests further user identity verification.
Continuous authentication enables the profiles to work with the bank’s risk solution. This integration helps determine the most accurate risk score to detect fraud. The advantage of continuous risk-based authentication is that it allows security teams to match the risk to the transaction requested. When combined, the authentication system and anti-fraud technology can expand the security coverage over a more extensive attack surface.
