Context of the organization 4. Leadership 5. Planning 6. Support 7. Operation 8. Performance evaluation 9. Improvement While the Clauses 1 to 3 are merely introductory, proper implementation of the Clauses 4 to 10 is mandatory to achieve compliance with the standard. The ISO requirements offer a risk-based approach to implementation and continuous improvement of corporate information security strategy based on a multifaceted ISMS, capable to adequately mitigate technical, physical, human and legal risks to the acceptable level.
Remarkably, under the standard, risk assessment and consequent risk mitigation plan may be unique for each organization: ISO does not dictate how to conduct risk assessment, neither sets a minimum bar for risk acceptance or tolerance.
This unique feature of ISO provides covered companies with a fairly broad flexibility, adjustable to their specific business context, needs and priorities. Of course, no ISO auditor in sound mind will agree with a risk treatment plan that contradicts common sense or is obviously at odds with the existing industry regulations or law.
Organizations looking for sound risk assessment and treatment methodologies may consider ISO standard that provides detailed guidelines on risk management. By the virtue of Clause 6. There are no specific security controls in the standard and the organizations are free to select their own security controls to mitigate the risks.
This gap is compensated by the Annex A to the ISO standard, which contains a non-exhaustive list of recommended but non-obligatory security controls aimed to provide more specific technical guidance to the organizations. Implementation of these security controls are elaborated by ISO The wide spectrum of security controls, spanning from physical safeguards and security training to supply chain risk management and meeting regulatory requirements, makes ISO one of the most comprehensive data protection standards.
For instance, the control A. The next control A. Privacy legislation is covered by the control A. It is important to note that the foregoing controls from the Annex A may be excluded if irrelevant for the ISMS scope or non-applicable for the organizational context. For instance, the A. Nonetheless, it is a good practice to consider all of the controls, avoid exclusions and properly document risk mitigation controls in case a currently non-applicable control becomes necessary one day.
One should also bear in mind that the controls from the Annex A is not a ceiling but rather a bottom line. When risk assessment requires supplementary security controls in order to adequately mitigate the identified risks to the acceptable level, additional controls must be implemented even if they are not expressly mentioned in the Annex. Cybersecurity professionals commonly follow divergent checklist approaches to tactical implementation of the ISO standard that may vary by country, industry or size of the certified business.
The underlying strategy is, however, pretty similar and consistent. First, the organization wishing to be ISO certified, shall analyze and agree on the underlying needs and the desired outcomes of the ISMS within the context of its business Clause 4. When doing so, the organization shall likewise consider legitimate needs and concerns of the so-called interested parties Clause 4.
The interested parties may include clients, partners, employees or regulators who may be positively or negatively affected by the ISMS implementation. For instance, customers will certainly appreciate more assurance that their data is adequately protected, while suppliers may give a cold welcome to additional due diligence requirements.
Commonly, small and medium-sized organizations select their entire infrastructure to be in the ISMS scope, while large international businesses may exclude some offices or locations where no sensitive data is processed or stored to reduce costs. Any unjustified or overbroad exclusions e. The next step is to obtain a long-term commitment from the organizational leadership Clause 5. The Clause 5. Eventually, organization shall unambiguously assign roles and responsibilities, and grant necessary authority to employees to fulfill their ISMS-related duties pursuant to the Clause 5.
In a nutshell, the subclauses 6. During this phase, the Statement of Applicability SoA comes into the game. This foundational ISMS document shall contain the list of necessary controls, justifications for their inclusion and implementation status, as well as justifications for exclusions if any. When properly managed it allows you to operate with confidence and extend this confidence to your customers.

However, without the ISO Information Security Management System ISMS , controls tend to be somewhat disorganized and disjointed, having been implemented often as point solutions to specific situations or simply as a matter of convention.
Security controls in operation typically address certain aspects of IT or data security specifically, leaving non-IT information assets such as paperwork and proprietary knowledge less protected overall.
Moreover, business continuity planning and physical security may be managed quite independently of IT or information security while Human Resources practices may make little reference to the need to define and assign information security roles and responsibilities throughout the organisation.
