Como você mede e relata a eficácia dos controles da ISO 27001?

Utilizar métricas alineadas a la ISO 27001 es clave. Dentro de estas métricas yo incluiría - Número de incidentes de seguridad. - Tiempo de respuesta a incidentes. - Tasa de cumplimiento de políticas de seguridad. - Eficacia de las medidas de mitigación. Tales indicadores deben cumplir con los requisitos SMART de las métricas (específicos, medibles, alcanzables, relevantes y limitados en el tiempo) Estas métricas no solo deben alinearse con el estándar ISO 27001, sino principalmente con los objetivos de la organización. Un buen sistema de indicadores es clave para medir la eficacia de la norma.

This shouldn't be done for any standard. Focus on integrating security into the vision, strategy, behaviours and processes of the organisation and then measure the things that are important. Measuring for a standard means the standard and its objectives are treated as separate from what the company actually does, leading to duplication of effort and no change in behaviour for the company or its employees, etc.

Demonstrating the effectiveness of ISO 27001 controls necessitates a two-pronged approach. Firstly, implement control monitoring practices like regular assessments and relevant KPIs (Key Performance Indicators) to quantify control functionality. Secondly, evaluate the overall ISMS (Information Security Management System) through risk management reviews and management engagement. By combining control-level data with ISMS effectiveness analysis, organizations can generate reports that not only showcase a robust information security posture but also highlight areas for improvement. These reports prove valuable for internal decision-making and external stakeholders during audits.

Drawing from my experience, collecting and analyzing data involves methodically sourcing information from audits, surveys, logs, and reports to support metrics and indicators. Establishing reliable sources, methods, and frequencies of data collection is critical, ensuring the validity of the gathered data. Utilizing diverse analysis techniques like trend analysis and root cause analysis, honed through my professional background, allows for thorough assessment of the Information Security Management System (ISMS) and its controls. Effective data collection and analysis, informed by experience, empower organizations to make informed decisions and drive continual improvement initiatives.

Reporting and communicating results of data analysis is a pivotal step in information security management. Leveraging my extensive experience, I craft concise yet comprehensive reports and dashboards that distill key metrics, indicators, findings, and recommendations for stakeholders. Tailoring communication to meet diverse audience needs, I ensure clarity and consistency in language and presentation style. By highlighting critical insights and facilitating open discussion, I empower stakeholders to make informed decisions and drive continuous improvement initiatives. Additionally, I follow up to track progress and address any challenges encountered, ensuring effective implementation of recommendations.

Do not forget that information security is not only the concern of IT companies; it is relevant for any industry. If information is still stored, transmitted, and updated on non-electronic media, the level of digitalization and stakeholders' perception will be different. Therefore, it's essential to address risks first and then focus on control mechanisms. Achieving efficiency in control mechanisms will primarily result in risk reduction. This will be clear to any information consumer who is interested in the system's creation and functioning.

Reviewing and improving controls within ISO 27001 is a vital process in maintaining a resilient Information Security Management System (ISMS). Leveraging my experience, I conduct thorough evaluations to assess control effectiveness and alignment with organizational objectives and risks. Identifying gaps and opportunities for enhancement, I draw from industry best practices and lessons learned to develop actionable improvement plans. By implementing targeted actions and monitoring their impact, I ensure continuous enhancement of security measures, fostering adaptability and resilience in the face of evolving threats.
