Security standards are a set of guidelines, best practices, and requirements that define how organizations should implement security controls and protect their information assets. Security standards provide a common language and framework for information security, allowing organizations to evaluate their security posture against industry-recognized benchmarks and compliance requirements. Some examples of security standards include the Payment Card Industry Data Security Standard (PCI DSS), the National Institute of Standards and Technology (NIST) Cybersecurity Framework, and the ISO 27001 standard.
