How To Comply With Iso 27001?

Imagine a world where cybersecurity threats are rendered futile; a utopia for businesses, big and small. This dream can become a reality, thanks to the robust frameworks provided by ISO 27001. However, complying with ISO 27001 is not as easy it may appear.

ISO 27001 is not just about deploying the best cybersecurity tools, but it also demands a methodical approach to managing and mitigating risks. A reported 43% of businesses had a data breach in 2019, underpinning the importance of ISO 27001 certification. Establishing and demonstrating the right information security management system becomes a cornerstone for long-term success in this digital era.

Understanding the Foundations of ISO 27001

In recent years, handling information security effectively has become paramount for organizations worldwide. One globally recognized standard that helps ensure this is the International Organization for Standardization’s ISO 27001. Now, the question that arises is, “how to comply with ISO 27001?” This article will guide youstep-by-step through the process.

Overview of ISO 27001 Standard

ISO 27001 is an international standard that sets the requirements for an Information Security Management System (ISMS). ISMS is a systematic approach consisting of processes, policies, and controls that helps to manage risks to the organization’s information thus ensuring secure business operations. By achieving ISO 27001 certification, an organization demonstrates that it has robust security measures in place to protect its information data.

Establishing an ISMS within an organization is not a trivial task. It requires understanding the risks associated with the organization’s data, identifying relevant security controls to address those risks, and implementing an effective risk management process. All these requirements are defined within the ISO 27001 standard.

The ISMS scope depends on the organization’s business requirements, objectives, and the size and structure of the organization. But no matter the scope, the intent remains unchanged – to protect information confidentiality, integrity, and availability.

ISO 27001 certification is not a one-time event, but a continuous process of maintaining and improving the organization’s information security. An external auditor reviews the implemented ISMS periodically to ensure the continuous effectiveness and improvement of the system.

Key Principles of ISO 27001

ISO 27001 revolves around several key principles which guides the organizations on their route towards compliance. Understanding these principles could aid a great deal in achieving a successful ISO 27001 implementation.

First and foremost is ‘Risk Assessment’. This involves identifying the assets, threats, vulnerabilities, impacts, likelihoods, and risk levels within an organization. It forms the foundation of the entire ISMS as it helps to identify where and how an organization might be at risk.

Another key element is the ‘Risk Treatment’. This translates to implementing controls to mitigate identified risks or accepting them, depending on their nature and potential impact. Risk treatment might also involve risk avoidance or sharing.

Process of ISO 27001 Compliance

Step 1: Define ISMS Scope, Policy, and Objectives

Defining the scope is the first step in ISO 27001 compliance. It involves identifying the business units, locations, and assets which are to be included within the ISMS.

After you define the scope, the next step is to establish an Information Security Management System (ISMS) Policy. This high-level policy should be aligned with the strategic context of the organization and should set out the management commitment and the objectives of the ISMS.

The objectives should be specific, measurable, achievable, relevant, and time-bound (SMART) and should support the ISMS policy. The performance against objectives should be monitored and reviewed regularly.

Beyond establishing policy and objectives, the organization should also establish roles and responsibilities for information security to ensure accountability at all levels.

Step 2: Conduct a Risk Assessment

Working on the basis of the defined scope and policy, the organization should conduct risk assessments systematically to determine the information risks it faces. Key aspects of risk assessment include risk identification, risk analysis, and risk evaluation. A risk owner should be identified for each identified risk.

As part of risk analysis, assets should be identified and their value or importance to the organization should be estimated. Threats to those assets and any existing vulnerabilities that may be exploited by the threats also need to be taken into consideration.

Risk evaluation should then be carried out to compare analysed risk levels against risk criteria to define whether risks are acceptable or need treatment.

Step 3: Implement Controls to Treat Risks

The next step in achieving ISO 27001 compliance is implementing controls to treat the unacceptable risks. ISO 27001 provides a catalogue of 114 controls in Annex A and guides on how and when to implement them. The organization, however, is free to select any additional controls necessary to address its specific risks.

The selection of controls is a crucial process and should be conducted in the context of the organization’s risk assessment. Apart from selecting controls, it also requires implementation of a risk treatment plan detailing what, who, when, and how of implementing the risk treatments.

The implementation might involve organizational, physical, or technological changes, and could potentially have cost implications, which need to be approved by management.

Once implemented, the effectiveness of these controls in managing the risks should be monitored and reviewed regularly, and improvements made if they are found to be ineffective.

Step 4: Launch an Employee Awareness Program

An employee awareness program is integral to the successful implementation of an effective ISMS. It is crucial that all employees understand what the ISMS is, why it is important, and the contribution that they are expected to make.

The awareness program should be ongoing and include all levels of staff within the organization, from executive management through to operational staff. The effectiveness of the awareness program should also be reviewed regularly.

Moreover, Improving employees’ skills in handling information securely, including how to handle password requests, what to do when they suspect an email is a phishing attempt, and understanding threats to data security, also forms part of this strategy.

Step 5: Continual Evaluation and Improvement

One of the key principles of ISO 27001 is that it should be a continual process. This means that once implemented, the ISMS should be monitored, reviewed, and evaluated for effectiveness and efficiency. Any non-conformities found should be addressed through corrective actions, and opportunities for improvement sought and implemented.

The system should be audited regularly to ensure that the controls are working as intended and achieving desired outcomes. This might be through internal audits, second or third party audits.

Further, management should review the system on a regular basis to ensure that it continues to be suitable, adequate, and effective in managing information security for the organization.

Facilitating Compliance with External Support

Enlisting Expert Assistance

Given the complexity and resource-intensive nature of implementing an ISMS and achieving ISO 27001 certification, many organizations choose to bring in external support. This could be in the form of consultancies specializing in ISO systems, training providers, or providers of easy-to-use tools and templates.

Such external resources can provide in-depth knowledge, experience and expertise in establishing an effective ISMS. They can help organizations view risks from multiple perspectives, suggest strategies for risk control, and provide insights into industry best practices.

Training can help empower employees, enhancing their understanding of information security threats and their ability to respond effectively. Through training, staff can also understand their role and responsibilities in maintaining the ISMS, creating a security conscious culture throughout the organization.

On the other hand, tools and templates can help streamline the process of establishing the ISMS, ensuring compliance with ISO 27001 requirements, tracking progress, and maintaining records for audit purposes.

Hiring a Certified Auditor

The ISO 27001 certification process involves a two-stage audit conducted by a Certification Body (CB). The CB should be accredited by a recognized body to certify against ISO 27001.

In Stage 1, the readiness of the organization to proceed to the full certification audit (Stage 2) is assessed. During this audit, the auditor will verify if the required procedures and controls have been developed as per the standard’s requirements. After the Stage 1 audit, a report is prepared that identifies any shortfalls in the organization’s ISMS.

Stage 2 involves a more detailed assessment of the ISMS, including testing the effectiveness of the controls. Once the auditor is satisfied that the organization has met all the requirements, they will recommend certification. Further surveillance audits are carried out subsequently to maintain the certification.

Implementing ISO 27001 is not just about compliance but about setting up a robust and effective system that protects your organization’s valuable information assets. Despite the complexity and hard work involved in achieving ISO 27001 compliance, the benefits such as enhanced security posture, increased business resilience, stakeholder trust, and compliance with legal and contractual requirements make it a worthwhile pursuit. Above all, an ISO 27001 certified ISMS will ensure a continual improvement approach to your organization’s information security, enabling you to stay prepared for evolving threats.
