By following the principles outlined in Clause 8.2, organizations can systematically identify, assess, and manage information security risks in a manner that aligns with their business context and objectives.
The organization shall perform information security risk assessments at planned intervals or when significant changes are proposed or occur, taking account of the criteria established in 6.1.2 a).
This clause emphasizes the importance of performing information security risk assessments at planned intervals or when significant changes are proposed or occur. Let’s break down the key components:
- Planned Intervals:Organizations need to establish a systematic and regular schedule for conducting information security risk assessments.The frequency of risk assessments should be determined based on the organization’s risk appetite, the pace of change in the business environment, and the effectiveness of current risk controls.
- Significant Changes: Whenever significant changes are proposed or occur within the organization, a risk assessment should be conducted.This includes changes such as the introduction of new technology, modifications to processes, changes in the business environment, or any other factors that may impact the information security risk landscape.
- Criteria Establishment: Criteria for the risk assessment process must be established. These criteria define how risks are identified, assessed, and treated.The criteria consider factors such as the organization’s risk tolerance, legal and regulatory requirements, and the potential impact on information assets.
- Practical Implementation:
- Risk Assessment Schedule:Develop a schedule that outlines when routine risk assessments will be conducted. The schedule should be based on the organization’s needs and risk landscape.
- Trigger Events:Define specific events or conditions that would trigger an ad-hoc risk assessment. This could include the introduction of new systems, changes in business operations, or other significant events.
- Criteria Definition:Establish clear criteria for conducting risk assessments. This includes the identification of assets, assessment of threats and vulnerabilities, and the evaluation of potential impacts.
- Documentation:Maintain documentation that outlines the schedule for routine risk assessments and the criteria used in the risk assessment process.
- Communication:Communicate the risk assessment schedule and criteria to relevant stakeholders. Ensure that employees are aware of the importance of reporting significant changes that may trigger an ad-hoc risk assessment.
- Integration with Change Management:Integrate the risk assessment process with the organization’s change management procedures. This ensures that changes are assessed for their potential impact on information security.
- Continuous Monitoring:Implement continuous monitoring mechanisms to stay vigilant for changes or events that may necessitate a risk assessment outside the planned intervals.
By adhering to these practices, organizations can establish a proactive and adaptive approach to managing information security risks. Regular risk assessments, combined with a responsiveness to significant changes, contribute to the ongoing effectiveness of an Information Security Management System (ISMS).
The organization shall retain documented information of the results of the information security risk assessments.
