A continuous information security monitoring program can best reduce risk through encompassing people, process, and technology. A continuous information security monitoring program is a process that involves maintaining the ongoing awareness of the security status, events, and activities of a system or network, by collecting, analyzing, and reporting the security data and information, using various methods and tools. A continuous information security monitoring program can provide several benefits, such as:
Improving the security and risk management of the system or network by identifying and addressing the security weaknesses and gaps Enhancing the security and decision making of the system or network by providing the evidence and information for the security analysis, evaluation, and reporting Increasing the security and improvement of the system or network by providing the feedback and input for the security response, remediation, and optimization Facilitating the compliance and alignment of the system or network with the internal or external requirements and standards A continuous information security monitoring program can best reduce risk through encompassing people, process, and technology, because it can ensure that the continuous information security monitoring program is holistic and comprehensive, and that it covers all the aspects and elements of the system or network security. People, process, and technology are the three pillars of a continuous information security monitoring program, and they represent the following:
People: the human resources that are involved in the continuous information security monitoring program, such as the security analysts, the system administrators, the management, and the users. People are responsible for defining the security objectives and requirements, implementing and operating the security tools and controls, and monitoring and responding to the security events and incidents.
Process: the procedures and policies that are followed in the continuous information security monitoring program, such as the security standards and guidelines, the security roles and responsibilities, the security workflows and tasks, and the security metrics and indicators.
Process is responsible for establishing and maintaining the security governance and compliance, ensuring the security consistency and efficiency, and measuring and evaluating the security performance and effectiveness.
Technology: the tools and systems that are used in the continuous information security monitoring program, such as the security sensors and agents, the security loggers and collectors, the security analyzers and correlators, and the security dashboards and reports. Technology is responsible for supporting and enabling the security functions and capabilities, providing the security visibility and awareness, and delivering the security data and information.
