Cybercrime, data leaks, legal requirements - the demands on information security are increasing. More and more companies are therefore relying on an ISMS in accordance with ISO/IEC 27001. But how do you start down this path in a professional and structured way? And what is really important at the beginning?
In this article, we show you the most important steps for introducing an information security management system - comprehensible, practical and focused on the essentials.
Why ISO 27001?
ISO/IEC 27001 is the globally recognized standard for information security. Companies that align themselves with this standard not only show customers and partners that they take responsibility - they also benefit internally from clear processes, fewer risks and greater transparency.
An ISMS helps to systematically identify information assets, assess risks and establish suitable protective measures. This not only strengthens IT security, but also trust in your company.
Preliminary step: Perform gap analysis
Before you start with the actual planning, a gap analysis is recommended. This involves systematically comparing the current state of information security in the company with the requirements of ISO/IEC 27001.
The aim of this analysis is to record existing measures, processes and documentation and identify potential gaps. The gap analysis creates transparency about the current level of maturity and forms a solid basis for setting realistic goals and priorities.
Step 1: Define responsibilities
The first step is to clearly define who will manage and be responsible for the introduction of the ISMS. This can be an information security officer - or an interdisciplinary project team.
It is important to note that the introduction of an ISMS is not an IT project, but a company-wide task that also involves management, specialist departments and, if necessary, external partners.
Step 2: Define objectives and scope
What exactly should the ISMS cover? Only IT? Or also specialist departments, service providers, mobile devices?
In this step, you define the so-called scope - i.e. the organizational and technical framework to which the ISMS should apply. At the same time, you formulate specific security objectives to which all measures are geared.
Step 3: Identify and assess risks
Risk management is a central element of ISO 27001. This involves identifying vulnerabilities, threats and the impact on information security - and deriving appropriate measures.
Typical risks can include a lack of access controls, insecure interfaces or human error. The aim is a structured assessment and prioritization in order to make the right decisions.
Step 4: Plan and document measures
Based on the risk assessment, you define specific security measures - both technical and organizational. These are documented in the Statement of Applicability (SoA).
Examples: Training for employees, encryption of data, emergency plans or the introduction of new processes for access control.
Step 5: Live and improve ISMS
An ISMS is not a one-off project - it is a living process. ISO 27001 requires regular audits, management reviews and improvements. After all, information security is never "finished", but must grow with the company.
