Definition
Compliance refers to adhering to established rules, standards, laws, and regulations within an organization or industry, particularly concerning data security and privacy. It involves implementing and maintaining specific controls and processes to meet these external or internal requirements. In practice, compliance dictates how systems are designed, data is handled, and security measures are applied to avoid penalties and maintain trust. For example, the General Data Protection Regulation (GDPR) mandates strict rules for processing personal data of EU residents, requiring organizations to implement robust data protection measures. Compliance is often confused with security itself, but it is a framework for achieving security objectives rather than security in its entirety. Understanding compliance is crucial for roles covered by certifications like CompTIA Security+, CySA+, and CISSP.
