Updating Policies, Procedures, and Controls

Lesson 28/30 | Study Time: 15 Min
Course: ISO 27035 Incident Management Fundamental Course Online

Regularly updating policies, procedures, and controls is a fundamental aspect of maintaining an effective and resilient incident management program.

These updates ensure that organizational frameworks remain aligned with evolving cyber threat landscapes, technological advancements, regulatory requirements, and lessons learned from past incidents.

ISO/IEC 27035 emphasizes continuous improvement through systematic revisions that address identified gaps and emerging risks, thereby enhancing preparedness and response capabilities.

Importance of Updates

Regular updates are essential to ensure that policies, procedures, and controls remain aligned with evolving business objectives, regulatory requirements, and threat landscapes. Below are the key areas that highlight why continuous review and adaptation are necessary.


1. Policies provide overarching principles and should reflect current organizational goals, legal mandates, and industry standards.

2. Procedures offer detailed, actionable steps that must adapt to new tools, threats, and operational learnings to remain practical and effective.

3. Controls, including technical, administrative, and physical safeguards, require periodic reassessment and enhancement to mitigate changing vulnerabilities.

Key Drivers for Updates


AspectDescription
Incident Lessons LearnedPost-incident reviews often reveal weaknesses or process inefficiencies requiring procedural refinements or policy adjustments.
Regulatory and Compliance ChangesNew laws or standards necessitate policy realignment and control enhancements to avoid penalties and ensure continued compliance.
Technological DevelopmentsAdoption of new technologies or security tools calls for corresponding updates to procedures and controls.
