The 5 Stages of a Successful ISO 27001 and Why Each Stage Matters

Due to the increased number of data breaches and cyber threats in the world, organizations require more than firewalls and passwords to secure sensitive information. ISO 27001 is the world standard of information security management system (ISMS) which is designed to overlay a structure to protect data and ensure business integrity.

Getting through an ISO 27001 certification is not a single event, but a process comprising a number of stages. All the stages are crucial in establishing a good security culture in the organization. Here, we will take a closer look at the 5 stages of a successful ISO 27001 journey and why each actually matters.

Stage 1: Commitment and Planning

Commitment by the leadership is the beginning of every successful ISO 27001 implementation. Senior management should be on the same side of the issue of establishing an ISMS and be ready to provide resources that are needed in the process.

Why It Matters:

Without the support of the leadership to provide leadership buy-in, there will be the risk of (ISO 27001 implementation) becoming a mere compliance exercise rather than a real cultural shift. At this level, it is important to plan so as to make the project have goals, scope, and responsibilities.

Key activities at this stage are:

• Identifying functions, processes and systems to be covered by the ISMS (scope of the ISMS).
• Delegation of duties and responsibilities, e.g. an ISMS manager or steering committee.
• Establishment of To-Do objectives which is consistent with organizational objectives.
• Setting a Budget and Resources.

Stage 2: Risk Assessment and Gap Analysis

The role of the first stage is to detect information security threats and evaluate the current situation with controls. Organizations perform a gap analysis in order to compare what is currently being practiced against what should be being practiced (according to ISO 27001).

Why It Matters:

The risk assessment is useful in order to prioritize work so that the resources available are focused on the areas where there are high levels of vulnerabilities. It also gives a starting point in continuous improvement.

Common Steps Include:

• Determining the assets, like data, hardware and intellectual property.
• Examining possible threats and sources of weakness.
• The calculation of risk probabilities and consequences.
• Comparing the existing security controls to the requirements of ISO 27001.

Stage 3: Security Controls Implementation

As soon as gaps are detected, companies proceed to take proper measurements that are outlined in Annex A of ISO 27001. These can be technical, organizational, and procedural.

Why It Matters:

This step reconverts the analyzed risks into defensive acts. The implementation of good controls will mitigate risk exposure to an acceptable level and ensure security practices as per ISO standards.

Examples of security controls:

• Access rule sets
• Secure protection of confidential information
• Planning incident response
• Continuity solutions
• Training/awareness of the employees

Stage 4: Management Review and Internal Audit

The internal audit should be carried out before an external certification audit to test the effectiveness of a company’s ISMS. Before concluding the whole audit, there is a management review where top managers examine the results of the audit and make decisions on what should be done.

Why It Matters:

Internal audits help put a reality check on how far the truth is about your account. They also keep the company up to date with ISO 27001 requirements and the areas in which a company should be stronger by the time the formal certification audit is carried out. The management review illustrates a commitment to and accountability of leadership.

Stage 5: Continuous Improvement and Certification Audit

The last step is a certification audit, which is done by a certified certification body. It normally happens in two stages:

Stage 1 Audit – Review of documentation, ISMS design, and readiness.

Stage 2 Audit- A detailed examination of the controls put in place, their effectiveness, and adherence.

Organizations also need to be subjected to surveillance audits once certification has been attained.

Why It Matters:

An attainment of certification represents the fact that the organization has a superior ISMS. The process does not finish at this point; ISO 27001 demands continuous improvement, i.e., organizations need to constantly evolve their activities in order to address emerging security issues.

Final Words

The 5 stages of a successful ISO 27001 journey are a combination of system building that will toil to create a robust information security management system. The process of planning and risk assessment, applying of controls and carrying out auditing ensures that it is not only a compliant but also a prepared organization to counter the changing security threats.
