ISO 27001 is an internationally recognised standard that sets the requirements for a best-practice information security management system (ISMS).
As we have previously discussed in detail in our previous blog, "What is the ISO 27001 Information Security Standard?", the standard guides organisations, regardless of size or industry, on how to build, manage, and protect vulnerable corporate data and information against various risks.
How do Security Domains form part of ISO 27001?
The Compliance Council explains that "ISO 27001 provides organisations with 10 clauses that serve as information security management system requirements and a section titled Annex A that outlines 114 controls that should be considered".
The 114 controls are then divided across 14 security domains, which provide the best practices for an information security management system (ISMS). These security domains help organisations perform a gap analysis to identify any areas of risk in their ISMS, as well as specify appropriate controls to address them.
While ISO 27001 is the most widely known ISMS standard, it is important to note that specific organisations (such as providers of employment skills training and disability employment services) may be required by the Australian Government to submit additional controls in order to gain certification.
In this article, we take a look at the 14 security domains specific to ISO 27001.
The Compliance Council details the Security Domains as below:
