Risk-based authentication assesses login attempts based on factors like device, location, network, and sensitivity. It enhances security and reduces unauthorized access.
Understanding risk-based authentication
With cyberattacks becoming increasingly sophisticated, organizations must employ effective authentication methods to protect their sensitive data and systems. One such method gaining traction is risk-based authentication (RBA). RBA utilizes real-time intelligence to gain a holistic view of the context behind each login attempt, allowing organizations to make informed decisions about granting access.

How does risk-based authentication work?
Risk-based authentication analyzes various factors to assess the level of risk associated with a login attempt. These factors include:
- Device: Is the user logging in from a known computer or a mobile device that has never been used before?
- Location: Is the user accessing the system from the same building or a different time zone?
- Network: Is the user logging in from a familiar IP address or an unknown source?
- Sensitivity: Is the requested file necessary for the company or relatively unimportant?
The risk-based authentication system can decide regarding the login attempt by considering these factors. The user may either be allowed to enter normally using a familiar system like a password or be required to provide additional verification to gain access.
Sophisticated risk-based authentication systems also analyze file requests. Even if users have access to the system, they may still need to verify their identity to access important files.
Benefits of risk-based authentication
Implementing risk-based authentication offers several benefits for organizations:
Widespread use
Government agencies widely use and promote risk-based authentication, making it familiar to many users.
Few deployments
Properly configured risk-based authentication systems only require additional steps from users in high-risk scenarios, ensuring a seamless user experience for most transactions.
Enhanced security
Risk-based authentication provides an extra layer of security by assessing the risk associated with each login attempt, reducing the likelihood of unauthorized access.
Proven compliance
Industries such as banking require stringent security measures. Adopting risk-based authentication principles helps organizations demonstrate their commitment to security and compliance.
However, organizations must carefully consider potential drawbacks before implementing risk-based authentication:
Deployment planning
Risk-based authentication requires careful planning and testing to ensure a predictable budget and avoid user access issues.
User training
Some users may need help adapting to new security measures. Effective communication and training are important to minimize user frustration.
Configuration considerations
Improperly configured risk-based authentication systems may lock users out of the applications they need or compromise security by allowing unauthorized access.

Key capabilities to look out for
When selecting a risk-based authentication solution, it is important to consider certain key capabilities:
Real-time threat data
The solution should have access to real-time threat data to identify potential security hazards and make informed risk assessments.
Contextual analytics
The ability to analyze the user's context, such as their device, location, and network connection, is significant in determining the risk level of a login attempt.
Flexible authentication procedures
Configuration policies should allow administrators to set up authentication procedures that are more secure than traditional password-based systems.
Integration with threat intelligence
Pairing risk-based authentication with threat intelligence solutions enhances risk assessment capabilities by analyzing data from various sources to uncover potential risks.
