Iso27k Mapping Iso 27001 to Pci-dss v1.2
At CIS, we believe in collaboration - by working together, we find real solutions for real cybersecurity threats. Our cybersecurity best practices grow more integrated every day through discussions taking place in our international communities and in the development of CIS SecureSuite Membership resources. CIS Controls — Prescriptive, prioritized, and simplified set of cybersecurity best practices. The are the definition of an effective cybersecurity program. CIS Benchmarks — Consensus-developed secure configuration guidelines for hardening operating systems, servers, cloud environments, and more. There are more than CIS Benchmarks covering more than 14 technology groups. We are in a multi-framework era where organizations large and small, public and private, are tasked with complying with multiple cybersecurity policy, regulatory and legal frameworks.
