In the present, many organizations place importance on achieving the ISO 27001 standard to gain confidence from their customers and staff in terms of information security quality. What exactly is ISO27001? Why is it important? And what components does it consist of? In this article, we will explore the answers
Meaning of ISO 27001 Standard
ISO 27001 is a standard for information security. It involves assessing risks and understanding vulnerabilities to allow organizations to systematically design information security measures. This starts from formulating, implementing, reviewing, and monitoring. Moreover, it also encompasses refining the system to keep it relevant to the current times, ensuring that the organization can adequately protect its information from theft.
The ISO 27001 standard employs the PDCA (Plan-Do-Check-Act) principle for its management approach. This involves considering and planning ahead before implementing according to the plan. Subsequently, the outcomes are checked to ensure they align with the initial plans. If the results don’t meet the expectations set out in the plan, corrective actions and improvements need to be made for the next planning cycle. Therefore, any organization that adopts the ISO 27001 standard is reflecting that it manages its information security according to international standards.
The benefits of ISO 27001 standard
1. Enhanced Confidence in the Organization:
Acquiring the ISO 27001 standard helps instill confidence in the organization from both customers and stakeholders, assuring that the information will be securely and effectively managed.
2. Increased Assurance in Information Management
When an organization can manage information with good confidentiality, it facilitates better management across various data aspects with assurance that information will not leak during operations.
3. Reduced Operational Risks
The ISO 27001 standard helps in reducing the risks of losses or damages caused by information leakage, preventing organizational operations from stalling and thereby ensuring smoother operations.
The four components of the ISO 27001 standard, as detailed from the given Thai passage, are as follows:
This step involves the actual execution of the plans made in the establishment phase. The operations are carried out according to manuals and work logs documented in forms. To ensure the implementation process is qualitative and yields good results, training should be provided to the team so they can follow consistent operational guidelines.
2. Monitoring and Review
This step focuses on assessing the outcomes of the actions from the implementation phase to determine if they align with the initial plans. Procedures for measuring outcomes and their frequency should correlate with the level of risk. If any part of the information is deemed high risk, more stringent monitoring and assessment measures are required. This ensures that the organization can quickly report unexpected incidents, enhancing its confidence in the system.
4. Continual Improvement
After conducting checks and identifying issues or abnormalities, involved parties must collaborate to resolve and prevent these issues from recurring in the future. Additionally, the involved team must find systematic ways to improve. High-level executives’ cooperation is essential to establish management policies that the team can adhere to in their practices.
In summary, ISO/IEC 27001 is a global standard for Information Security Management System (ISMS). Its focus is on protection, control, and continual enhancement of security management across all aspects, be it people, work processes, or technologies within an organization. This standard ensures that information within an organization is handled securely and with due diligence.
This involves setting up an information security management process. A suitable and sufficient team should be designated based on the volume of an organization’s data. This team is tasked with creating a system that aligns with the nature of the work and identifies vulnerabilities that could pose threats to the organization’s information.
