Objectives of an Information Security Management System
- Protect customer and employee data
- Reduce the likelihood of security breaches
- Ensure business continuity
- Improve control over information assets
- Comply with legal and regulatory requirements

Reducing Security Risks
The standard helps identify threats and vulnerabilities and implement appropriate controls to minimize their impact.
Regulatory Compliance
It supports compliance with data protection and privacy laws, particularly in sensitive and regulated sectors.
Clarifying Roles and Responsibilities

Steps to Implement ISO/IEC 27001
Application Form Completion
The process of obtaining ISO/IEC 27001 certification begins with completing the certification application form submitted to the certification body. This form includes basic information about the organization, such as the nature of its activities, number of employees, locations, and the scope of the Environmental Management System to be certified.
Preparation of the Audit Plan
After reviewing the application form, an audit plan is prepared outlining the audit dates, scope, covered processes, and the names of the audit team members. The purpose of this plan is to organize the audit process and ensure that all requirements of the standard are fully covered.
Audit – Stage 1 (Audit Stage 1)
The objective of the Stage 1 audit is to assess the organization’s readiness for certification. This includes reviewing environmental documentation and policies, verifying understanding of ISO/IEC 27001 requirements, and confirming their initial implementation, while identifying any gaps that need to be addressed before proceeding to the next stage.
Audit – Stage 2 (Audit Stage 2)
At this stage, the actual on-site audit is conducted. Auditors review the implementation of the Environmental Management System within the organization and verify full compliance with ISO/IEC 27001 requirements. If there are no major nonconformities, or after they have been closed, a recommendation is made to grant the certification.
