ISO 27001 is the internationally recognized standard for Information Security Management Systems (ISMS). During an ISO 27001 audit, organizations must provide verifiable evidence to demonstrate compliance with the standard’s requirements. The audit process evaluates how effectively the ISMS is implemented and maintained. To ensure success, organizations must prepare and present well-documented evidence that reflects the policies, processes, and controls aligned with ISO 27001.

This blog outlines the key types of evidence required and how businesses—especially those seeking ISO 27001 Certification in Bangalore—can prepare effectively with the support of ISO 27001 Consultants in Bangalore and ISO 27001 Services in Bangalore.

1. Information Security Policy and Objectives

One of the first pieces of evidence auditors look for is the organization’s information security policy. This document must be approved by top management and clearly communicate the organization’s objectives and commitment to information security.

Evidence includes:

  • Documented information security policy

  • Defined and measurable security objectives

  • Records of policy reviews and updates

2. Risk Assessment and Risk Treatment Records

Risk management is at the core of ISO 27001. Auditors will assess how the organization identifies, evaluates, and treats risks.

Required evidence includes:

  • Documented risk assessment methodology

  • Risk assessment results

  • Risk treatment plan

  • Risk acceptance records

  • Statement of Applicability (SoA)

3. Scope of the ISMS

Defining the scope is crucial to determine which assets and departments fall under ISO 27001 compliance.

Evidence includes:

  • ISMS scope document

  • Justifications for exclusions

  • Mapping of assets and systems within the scope

4. Internal Audit Reports

Internal audits help ensure that the ISMS is functioning as intended. Auditors will verify whether these are conducted regularly and effectively.

Required evidence includes:

  • Internal audit plan and schedule

  • Audit reports

  • Nonconformity reports and corrective actions

  • Records of auditor qualifications

5. Management Review Records

Management reviews ensure the ISMS remains aligned with strategic direction and is continually improved.

Evidence includes:

  • Meeting agendas and minutes

  • Input and output records (e.g., audit results, risk changes)

6. Training and Awareness Programs

Competence and awareness of employees are vital to ISMS success.

Required documentation includes:

  • Training schedules and materials

  • Attendance records

  • Competency evaluations

  • Awareness communication logs

7. Incident Management Records

Auditors will check how the organization identifies and manages security incidents.

Evidence includes:

  • Incident logs

  • Root cause analysis

  • Corrective and preventive actions taken

  • Communication with stakeholders (if applicable)

8. Monitoring and Measurement Records

To ensure that controls are effective, organizations must monitor performance regularly.

Documentation includes:

  • Monitoring logs (e.g., access logs, system activity)

  • Performance measurement results

  • Records of control evaluations

  • Evidence of continual improvement actions

9. Access Control and Physical Security Logs

Protection of physical and digital access is fundamental to ISO 27001.

Auditors will look for:

  • Access control policies and procedures
