Objective of Control 8.9

The objective of this control is to ensure that configurations of hardware, software, services, and networks are securely established, documented, monitored, and maintained throughout their lifecycle. This protects the organization’s IT assets from unauthorized modifications and aligns them with the organization’s security requirements.

Purpose of Control 8.9

The purpose of this control is to ensure that your hardware, software, services, and networks operate seamlessly with the necessary security settings. Proper configuration management prevents unauthorized or erroneous modifications, reducing the risk of downtime, data breaches, or compliance violations.
Configuration management also supports your organization’s overall information security by enabling proactive monitoring and enforcement of secure settings.

Main Requirements of ISO 27001 Control 8.9

To implement effective configuration management, your organization should:

  • Establish and Document Configurations: Define secure configurations for all IT assets, considering industry best practices and vendor recommendations.
  • Implement Processes and Tools: Use automated tools to enforce configurations, ensuring consistent application across systems.
  • Monitor and Review Configurations: Regularly verify and update configurations to address emerging threats and maintain alignment with your organization’s security policies.
  • Manage Changes: Ensure all configuration changes follow a structured change management process to avoid unauthorized modifications.

Standard Templates for Secure Configuration

Using standard templates ensures consistency and security across your IT environment. Here’s how your organization can benefit from these templates:

  1. Leverage Industry Best Practices: Use  templates from vendors and security organizations to define configurations.
  2. Address Specific Security Needs: Customize templates based on your organization’s risk tolerance and regulatory requirements.
  3. Regular Updates: Periodically review and update templates to address new vulnerabilities, threats, or updates in hardware and software.

Key considerations for secure templates:

  • Minimize privileged access.
  • Disable unnecessary services.
  • Enforce time-out settings for inactive sessions.
  • Immediately change default passwords upon installation.

Managing and Recording Configurations

Through integrating configuration management with asset management, you gain better visibility and control over your IT infrastructure. Effective configuration management involves defining configurations and maintaining records:

  • Maintain Logs: Keep a detailed log of all configurations and changes, including asset ownership and the date of the last modification.
  • Secure Storage: Store configuration records securely to prevent unauthorized access.
  • Version Control: Track configuration template versions to ensure accurate implementation.

Monitoring and Auditing Configurations

Monitoring configurations is a proactive way to ensure that your systems remain secure. Tools like enterprise management software, backup solutions, and infrastructure monitoring utilities can help:

  • Regular Audits: Compare actual configurations against defined templates to identify discrepancies.
  • Address Deviations: Resolve deviations promptly through automated enforcement or manual corrective actions.
  • Comprehensive Reviews: Periodically assess password strengths, configuration settings, and system activities to maintain a robust security posture.

Automation in Configuration Management

Automation is an effective way to improve your configuration management. It establishes consistency and reduces the risk of human errors. Tools like infrastructure-as-code enable your organization to automate configuration enforcement, making it easier to manage security settings across multiple systems. Automated solutions also simplify monitoring and streamline compliance reporting.
