Compliance in IT security means establishing and operating safeguards, policies, processes, and governance practices that meet applicable legal, regulatory, contractual, customer, insurance, or framework requirements. Effective compliance is more than preparing documents for an assessment. It includes identifying risks, assigning control ownership, collecting evidence, monitoring control performance, addressing gaps, and maintaining the program as the organization and its obligations change.
