Learn how Rublon MFA can secure all access to Cardholder Data Environment (CDE) with a cutting-edge multi-factor authentication tailored for securing payment systems ensuring regulatory compliance with PCI DSS v4.0.
Scenario
A business handling payment card data needs to secure its Cardholder Data Environment (CDE) to comply with the updated PCI DSS 4.0 requirements, specifically Requirements 8.3 and 8.4.2, which mandate the use of Multi-Factor Authentication (MFA) for all access to the CDE.
Challenge
With the introduction of PCI DSS 4.0, the requirements for MFA have expanded beyond just administrative access. Now, all users who need access to the CDE must be challenged with MFA every time they attempt to access the environment, regardless of whether the request originates from within the same network or remotely. This means that MFA must be implemented for various system components, including cloud environments, hosted systems, on-premises applications, network security devices, workstations, servers, and endpoints. Enabling multi-factor authentication (MFA) for all these resources can be complex and time-consuming, but it is essential for maintaining compliance and protecting sensitive cardholder data.
Solution
Implement Rublon MFA across all access points to the Cardholder Data Environment (CDE). Rublon MFA can ensure that every user is challenged with MFA whenever they attempt to access the CDE. This includes using protocols like RADIUS, LDAP(S), and SAML, as well as dedicated plugins, connectors, and SDKs to apply MFA to all system components that interact with the CDE, such as cloud environments, hosted systems, on-premises applications, and network security devices. Rublon’s comprehensive MFA solution simplifies compliance with PCI DSS 4.0 by ensuring that all access to the CDE is secured.
Benefits
Rublon MFA ensures that the organization meets the stringent requirements of PCI DSS 4.0 by securing all access to the CDE with strong, repeated MFA challenges. Rublon’s MFA solution ensures that every access attempt to the CDE, whether from an internal or external source, is authenticated through a rigorous, multi-layered process. This continuous authentication model significantly mitigates the risk of credential-based attacks, such as phishing or session hijacking, by requiring users to prove their identity every time they access sensitive data.
