ISO 27001: Information Security Management System

ISO 27001 is an international standard for information security management systems and is the most widely accepted information security management standard worldwide. Compliance with this standard enables organizations to systematically manage their information security processes, control security risks, and ensure continuous improvement.

As the Istanbul-based BARLAS Cyber Security team, we provide end-to-end support in ISO 27001 consulting, information security management system (ISMS) setup, certification preparation, cybersecurity testing, and KVKK / GDPR compliance projects to organizations operating in Istanbul, Türkiye, and Europe.

What is ISO 27001?

ISO 27001 (Information Security Management System - ISMS) is an international standard that specifies requirements for establishing, implementing, maintaining, and continuously improving information security management systems. This standard is also known as ISO/IEC 27001:2013 and was published by the International Organization for Standardization (ISO).

ISO 27001 uses a management system approach based on the Plan-Do-Check-Act (PDCA) cycle. This approach enables organizations to systematically manage their information security risks.

ISO 27001 Core Principles

The ISO 27001 standard is based on the following core principles:

• Risk-Based Approach: Organizations should identify, assess, and apply controls to reduce information security risks to acceptable levels.
• Continuous Improvement: The information security management system must be continuously improved through regular reviews and improvements.
• Management Commitment: Top management must fully support the information security management system and provide necessary resources.
• Stakeholder Needs: The system must meet the information security needs of relevant parties (customers, employees, stakeholders).

ISO 27001 Main Components

The ISO 27001 standard consists of the following main sections:

1. Context and Scope

Determination of the organization's internal and external context, identification of interested parties and their needs, and determination of the scope of the information security management system.

2. Leadership

Top management's determination of information security policy, assignment of roles and responsibilities.

3. Planning

Risk assessment and preparation of risk treatment plan, determination of information security objectives.

4. Support

Provision of resources, competence and awareness training, documentation control.

5. Operation

Implementation of risk treatment plan and management of operational controls.

6. Performance Evaluation

Monitoring, measurement, analysis, and evaluation, internal audits, management review.

7. Improvement

Correction of nonconformities and continuous improvement activities.

ISO 27001 Advantages

ISO 27001 compliance provides organizations with the following advantages:

• Risk Management: Systematic identification and management of information security risks
• Legal Compliance: Facilitating compliance with data protection laws such as KVKK and GDPR
• Customer Trust: Increased trust of customers and business partners
• Competitive Advantage: Providing reliability and competitive advantage in the market

Relationship between ISO 27001 and ISO 27701

ISO 27701 is an extension of ISO 27001 and provides additional requirements for privacy information management systems. When ISO 27001 is used as a base, compliance with data protection laws such as KVKK and GDPR can be achieved with ISO 27701.

ISO 27001 Certification Process

The general process for ISO 27001 certification consists of the following steps:

1. Gap Analysis: Evaluation of current status according to ISO 27001 requirements
2. Planning: Design of ISMS and preparation of implementation plan
3. Implementation: Implementation of policies, procedures, and controls
4. Internal Audit: Verification of the system through internal audit
5. Management Review: Top management reviewing system performance
6. External Audit and Certification: Audit and certification by an independent certification organization
