Understand the Requirements of ISO/IEC 27001 Information Security Management System

Maximum organizations have a number of information security controls. However, without an ISO/IEC 27001 information security management system, controls tend to be somewhat disorganized, having been implemented often as point solutions to precise situations as a matter of convention. Security controls in operation typically address confident aspects of information technology or data security precisely; leaving non-IT information assets less protected on the whole. Moreover, business continuity planning and physical security may be accomplished quite independently of IT or information security while Human Resources practices may make little reference to the essential to define and assign information security roles and responsibilities throughout the organization.

Requirements of ISO 27001:

The main requirements of the ISO 27001 standard are addressed below:

The Organization and its Context: The ISO 27001 requirements is about understanding the organization and its context. Always recommend this is where an organization starts with its ISO 27001 implementation.

The Scope of the Information Security Management System: ISO 27001 standard contains setting the scope of Information Security Management System. This is a critical part of the ISMS as it will tell stakeholders, with senior management, consumers, auditors and staff, what areas of business are covered by ISMS. Organization should be able to rapidly and simply define scope to an auditor.

Leadership & Commitment: This leadership focused of ISO 27001 emphasizes the importance of information security being supported, both evidently and materially, by senior management. This identifies precise aspects of the management system where top management are probable to demonstrate both leadership and commitment.

Information Security Policy: The ISO/IEC 27001 needs that top management establish an information security policy. This requirement for documenting a policy is pretty straightforward. However, it is what is private the policy and how it relates to the bigger ISMS that will give interested parties the confidence they want to trust what sits behind the policy.

Organizational Roles, Responsibilities & Authorities: This is all about top management confirming that the roles, responsibilities and authorities are clear for the ISMS. This does not mean that the organization wants to go and appoint some new staff or over engineer the resources complicated – it’s an often-misunderstood expectation that puts smaller organizations off from accomplishing the standard.

Actions to Address Risks and Opportunities: the ISO 27001 necessities is about planning, and precisely the planning of actions to address risks and opportunities. Risk management is pretty straight forward however it means different things to different people, and it means something precise to ISO 27001 auditors so it is significant to meet their requirements.

Information Security Objectives & Planning to Achieve them: Probably know why want to execute ISMS and have some top line organization goals around what success looks like. The business case builder materials are a beneficial aid to that for the more strategic outcomes from management system. Starts to make this more assessable and relevant to the activities around information security in particular for protecting confidentiality, integrity and availability of the information assets in scope.

Resources: The establishment, implementation, maintenance, and ongoing improvement of the information security management system must be supported with an acceptable number of resources, according to ISO 27001 requirements. As previously mentioned with regard to the leadership resources, ISO 27001 only requires that the roles, responsibilities, and authorities are clearly defined and owned – presuming that the appropriate level of resource will be applied as necessary. It does not actually require that the ISMS be staffed by full-time resources.

Competence: ISO/IEC 27001 essentially says that the organization will confirm that it has:

• Determined the capability of the people doing the work on the ISMS that could affect its performance.
• People that are considered competent on the basis of the relevant education, training or experience.
• where mandatory, taken action to acquire the essential competence and evaluated the effectiveness of the actions.
• Retained evidence of the above for audit purposes.

Documented Information: Anyone familiar with operating to a recognized international ISO 27001 standard will know the importance of documentation for the management system. One of the chief requirements for ISO 27001 is therefore to define information security management system and then to prove how its intended outcomes are accomplished for the organization. It is very important that everything related to the ISO 27001 documents Information Security Management System and well maintained, easy to find, if the organization wants to accomplish an independent ISO 27001 certification form a body like UKAS. ISO certified auditors take great assurance from good housekeeping and maintenance of a well-structured information security management system.

Operational Planning & Control: This is very easy to demonstrate evidence against if the organization has already ‘showed its workings’. In developing the information security management system to obey with necessities and in particular where the whole ISMS is well structured and documented. It is about planning, implementation and control to confirm the outcomes of the information security management system are accomplished.

Information Security Risk Assessment: ISO 27001 that gets automatically accomplished where the organization has already evidenced its information security management work in line with requirements and in particular where the whole ISMS is clearly documented. The organization must perform information security risk assessments at planned intervals and when changes require it – both of which essential to be clearly documented.

Information Security Risk Treatment: The requirement is for the organization to execute the information security risk treatment plan and retain documented information on the results of that risk treatment. This requirement is therefore concerned with confirming that the risk treatment process defined, are actually taking place. This should contain evidence and clear audit trials of reviews and actions, showing the movements of the risk over time as results of investments emerge.

Management Review: It is the responsibility of senior management to conduct the management review for ISO 27001. These assessments should be pre-planned and often enough to confirm that the information security management system remains to be effective and accomplishes the goals of the business. ISO itself says the reviews should take place at strategic intervals, which usually means at least once per annum and within an external audit surveillance period. However, with the pace of change in information security threats, and a lot to cover in management reviews, our recommendation is to do them far more regularly.

Continual Improvement: A huge part of running an information security management system is to see it as a living system. Organizations that take improvement seriously will be measuring, testing, reviewing and measuring the performance of the ISMS as part of the broader led strategy, going beyond a ‘tick box’ regime. There are some mechanisms already covered within ISO 27001 for the constant evaluation and improvement of the ISMS.
