According to ISO/IEC 27001:2022, which specifies the requirements for establishing, implementing, maintaining and continually improving an information security management system (ISMS), an organization should select and implement appropriate controls to achieve its information security objectives1. The controls should be derived from the results of risk assessment and risk treatment, and should be consistent with the Statement of Applicability (SoA), which is a document that identifies the controls that are applicable and necessary for the ISMS1. The controls can be selected from various sources, such as ISO/IEC 27002:2013, which provides a code of practice for information security controls2. Therefore, if an auditor in training has been tasked with reviewing the technological controls listed in the SoA and implemented at the site of an organization that stores data on behalf of external clients, four controls that would be expected to review are:
How protection against malware is implemented: This is a technological control that aims to prevent, detect and remove malicious software (such as viruses, worms, ransomware, etc.) that could compromise the confidentiality, integrity or availability of information or information systems2. This control is related to control A.12.2.1 of ISO/IEC 27002:20132.
How the organisation evaluates its exposure to technical vulnerabilities: This is a technological control that aims to identify and assess the potential weaknesses or flaws in information systems or networks that could be exploited by malicious actors or cause accidental failures2. This control is related to control A.12.6.1 of ISO/IEC 27002:20132.
How access to source code and development tools are managed: This is a technological control that aims to protect the intellectual property rights and integrity of software applications or systems that are developed or maintained by the organization or its external providers2. This control is related to control A.14.2.5 of ISO/IEC 27002:20132.
The operation of the site CCTV and door control systems: This is a technological control that aims to monitor and restrict physical access to the premises or facilities where information or information systems are stored or processed2. This control is related to control A.11.1.4 of ISO/IEC 27002:20132.
The other options are not examples of technological controls, but rather organizational, legal or procedural controls that may also be relevant for an ISMS audit, but are not within the scope of the auditor in training's task. For example, the development and maintenance of an information asset inventory (related to control A.8.1.1), rules for transferring information within the organization and to other organizations (related to control A.13.2.1), confidentiality and nondisclosure agreements (related to control A.13.2.4), verification checks on personnel (related to control A.7.1.2), remote working arrangements (related to control A.6.2.1), information security within supplier agreements (related to control A.15.1.1), business continuity arrangements (related to control A.17), information deletion (related to control A.8.3), information security awareness, education and training (related to control A.7.2), equipment maintenance (related to control A.11.2), and how power and data cables enter the building (related to control A.11) are not technological controls, but rather organizational, legal or procedural controls that may also be relevant for an ISMS audit, but are not within the scope of the auditor in training's task.
