PCI DSS Requirement 2: Securely Configure System Components
Blog post from Basis Theory
PCI DSS Requirement 2 aims to reduce the risk of system compromise by requiring organizations to replace vendor default credentials and settings, remove unnecessary accounts, software, services, protocols, and functions, and maintain secure configurations across system components. Its first section requires documented, current, and understood security policies, procedures, roles, and responsibilities; its second requires configuration standards that address vulnerabilities, protect administrative access with strong encryption, isolate functions with different security needs, and document safeguards for any insecure protocols that remain necessary. The requirement also addresses wireless environments connected to cardholder data systems or transmitting account data, requiring secure default settings and changes to encryption keys when authorized personnel leave or a compromise is suspected. Basis Theory states that its PCI Level 1-compliant platform can help businesses secure and handle cardholder data without bringing their own systems fully into PCI scope, though readers are directed to the PCI Security Standards Council for authoritative and current requirements.
