PCI-DSS requirement 2.2 guide organizations to: “develop configuration standards for all system components. 1.3. Reducing available ways of attack typically includes changing default passwords, the removal of unnecessary software, unnecessary usernames or logins, and the disabling or removal of unnecessary services. Five Steps to Comply with PCI DSS Requirement 2.2, 1: Understand that you are not secure right out of the box, Make sure servers have not more than one primary role, PCI DSS Requirement 2.2 does not have a Quick Button to fulfill, Additional tips to consider about PCI DSS requirement 2, International Organization for Standardization (ISO), SysAdmin, Audit, Network, and Security (SANS) Institute, National Institute of Standards and Technology (NIST). For hardening or locking down an operating system (OS) we first start with security baseline. Windows Server Preparation. The PCI DSS requirements apply to all system components, including people, processes and technologies that store, process or transmit cardholder data or sensitive authentication data, included in or connected to the cardholder data environment. There are several important steps and guidelines that your organization should employ when it comes to the system or server hardening best practices process. PCI DSS Requirement 2.2 portion is kind of like training a race car. A hardening standard is used to set a baseline of requirements for each system. To ensure that business critical or necessary functionality is not compromised, it is essential to conduct testing during the hardening process. National Institute of Standards and Technology, nor is it intended to imply that the entities, materials, or equipment are necessarily the best available for the purpose. The firewall rule base must be reviewed at least quarterly and the change management process created to add and push the policy to the firewall. The PCI DSS, and particularly PCI Requirement 2.2, does not have an easy button. The goal is to enhance the security level of the system. The level of classification defines what an organization has to do to remain compliant.
