Controls Guide for ISO 27001 – Part 1

This article is part of our ISO 27001 compliance and certification hub page, created to help organizations understand the standard, its requirements, and its role in information security management. In this first part of the ISO 27001 controls guide, we explain the foundational controls that support risk management, data security, and a structured approach to protecting business-critical information.

An international standard called ISO/IEC 27001:2013 was developed to assist enterprises in managing the security procedures for their information assets. This standard offers a reliable framework for putting into place an ISMS, or Information Security Management System. Through its safe and efficient management procedures, this framework facilitates the Confidentiality, Integrity, and Availability of all crucial organizational data.

One of the most widely used and approved information security standards is ISO 27001. You can refer to our prior article for more information because we already covered everything you need to know about the ISO 27001 standard.

What are the audit controls for ISO 27001?

There are two sections to the ISO 27001 Audit Control Standards.11 clauses, ranging from 0 to 10, make up the first section, which is the required element. 114 control objectives and controls are outlined in the second section, known as Annex A. The Introduction, Scope, Normative references, and Terms and Definitions of the ISO 27001 standard are covered in Clauses 0 to 3.

Any business that wants to be in compliance with the Standard must adhere to the ISO 27001 requirements listed in Clauses 4 through 10.
