Key ISO Standards in Information Security​

Here are the most widely used ISO standards that every cybersecurity professional should know:

ISO/IEC 27001: Information Security Management Systems (ISMS)​

The ISO/IEC 27001 standard sets the foundation for managing information security through a structured Information Security Management System (ISMS).
It helps organizations:

• Identify and mitigate risks
• Protect confidentiality, integrity, and availability of data
• Align with global compliance frameworks (like GDPR or HIPAA)

ISO/IEC 27002: Security Controls​

This companion standard provides practical guidelines and examples for implementing security controls. It’s like a “how-to” guide for achieving the goals of ISO 27001.

It covers areas like:

• Access control
• Cryptography
• Asset management
• Human resource security

ISO/IEC 27017 & 27018: Cloud Security and Privacy​

As cloud computing dominates modern IT environments, ISO 27017 and ISO 27018 focus on protecting data stored and processed in the cloud.
They help cloud service providers and clients ensure that privacy, confidentiality, and data governance are handled responsibly.

Compliance: Meets international legal and regulatory requirements.
Continuous Improvement: Encourages regular audits and updates to security policies.

Steps to Get ISO 27001 Certified​

1. Conduct a gap analysis to identify missing security measures.
2. Build your ISMS documentation (policies, risk assessments, controls).
3. Train your employees and raise awareness .
4. Perform an internal audit.
5. Undergo a third-party audit for certification.

Once certified, maintain and improve your ISMS continuously to retain compliance.
