ISO 27001 Information Security Management System
Sparta Cyber Security’s Lead Auditors and ISMS Consulting Team are ready to provide end-to-end guidance for organizations looking to establish or enhance an Information Security Management System (ISMS). By delivering tailored solutions that address your organization’s specific needs, we help you successfully implement and maintain an ISO 27001-compliant ISMS. Our goal is to support our clients in protecting assets, minimizing risks, and ensuring compliance by applying proven strategies and international best practices.
What is ISO/IEC 27001 ISMS?
ISO/IEC 27001 ISMS represents a structured framework for managing sensitive information securely. Its primary objective is to safeguard critical data, including employee information, digital assets, and business processes.
It is the most widely recognized international standard used to establish, operate, maintain, and continually improve an organization's information security management practices. The standard outlines essential principles for launching, implementing, and refining ISMS initiatives.
For sector-specific security controls and implementation methods, organizations are expected to refer to harmonized international standards such as ISO/IEC TR 27019, NIST SP 800 series, or IEC/TS 62443, depending on their operational context.
Within ISO/IEC 27001, the PDCA (Plan–Do–Check–Act) model is applied to manage and improve the ISMS lifecycle, including design, operation, monitoring, review, and continual improvement.
Purpose and Benefits of ISMS
To ensure the protection and effectiveness of organizational data, systems, and infrastructure, a structured set of policies, procedures, control mechanisms, and analysis tools must be in place. Prior to certification, various preparatory activities in line with ISO/IEC 27001 must be carried out internally.
To meet this need, Sparta’s team begins by analyzing the vulnerabilities and threats revealed during offensive security testing. We assess potential risks to your critical systems and data, then develop security policies, procedures, documentation, asset inventories, and risk analyses in full compliance with ISO/IEC 27001. Utilizing the PDCA methodology, we prepare your organization for formal certification audits with a comprehensive and practical approach.
Who is Required to Implement an ISMS?
Legal requirements for ISMS implementation are outlined in various national regulations. If your institution or company falls within the scope of the following mandates, establishing an ISMS is mandatory:
- Public Sector Institutions: Government agencies must implement an ISMS to comply with the “Minimum Security Requirements for Joining the KamuNet Network.”
- Electronic Communications Sector: Capital-based companies operating electronic communication networks and infrastructures are required by the Information and Communication Technologies Authority (ICTA/BTK) to be ISO/IEC 27001 certified since July 20, 2010
- Customs and Trade: Exporters and importers applying for Authorized Economic Operator (AEO) certification must obtain ISO/IEC 27001:2013 certification under the Trade Facilitation Regulation.
- Electricity Distribution Companies: As mandated by the Energy Market Regulatory Authority (EPDK), electricity distributors must be certified in ISO/IEC 27001. Furthermore, the regulation published in the Official Gazette dated February 2017 (No. 29989) requires these companies to reference ISO/IEC TR 27019 in addition to the ISO/IEC 27002 Implementation Guide while developing their ISMS.
- Elektrik Dağıtım Şirketleri: Elektrik Piyasası Düzenleme Kurulu (EPDK) tarafından TS ISO/IEC 27001 Bilgi Güvenliği Yönetim Sistemi Belgesi alınması zorunlu hale getirilmiştir. Ayrıca Şubat 2017 tarihli ve 29989 sayılı Resmi Gazetede yayımlanan yönetmelik değişikliği ile elektrik dağıtım şirketlerinin TS ISO/IEC 27001’e göre kuracakları Bilgi Güvenliği Yönetim Sisteminde TS ISO/IEC 27002 Uygulama Rehberine ek olarak ISO/IEC TR 27019 rehber dokümanını da referans almaları zorunludur.
