A well-constructed information security management system is an crucial to every business’s operations. It ensures compliance with laws, minimizes risk to acceptable levels and protects organizational and customer data. It also provides employees with clear policy documents, training and clear guidelines on how to spot and deal with cyber-attacks.
An organization may create an ISMS for various reasons, including to improve cybersecurity and compliance with regulatory requirements, or to seek ISO 27001 certification. The process involves conducting an analysis of risks, identifying the potential vulnerabilities, and selecting and implementing controls to minimize the risk. It also defines roles and responsibilities of committees and owners of specific security procedures and activities. It also creates a policy document, records it and implements an improvement program.
The scope of an ISMS depends on the information systems a company thinks are most crucial. It also considers any applicable regulations and standards, such as HIPAA for a healthcare organization or PCI DSS for an e-commerce platform. An ISMS usually includes methods for detecting and responding to threats, including identifying the source of a threat and monitoring access to data to track who is accessing the information.
It is crucial that all stakeholders and employees are involved in the process of establishing an ISMS. It is usually best to start with the PDCA (plan do, plan check and act) model. This will allow the ISMS system to be able to adapt to the latest cybersecurity threats and regulations.
