Azure Security Center (ASC) is a cloud-based security management tool that helps organizations to detect, prevent, and respond to security threats in their Azure environment. One of the critical features of ASC is the Secure Score, which measures an organization’s overall security posture. This blog post will discuss some best practices for maintaining a high Secure Score in Azure Security Center for clients. We will cover the different areas that contribute to the Secure Score, as well as steps that can be taken to improve it.
1. Understanding the Azure Security Center Secure Score
The Azure Security Center Secure Score is a measure of an organization’s overall security posture. It is based on a set of security controls divided into three categories: foundational, adaptive, and advanced. The foundational controls are those that are considered essential for basic security, while the adaptive controls are those that are recommended for specific scenarios. Advanced controls are those that are recommended for advanced security scenarios. The Secure Score is calculated based on the number of controls enabled and configured correctly.
2. Enabling and Configuring Azure Security Center
The first step in maintaining a high Secure Score is to enable and configure Azure Security Center. This involves setting up the ASC service, creating and configuring the ASC policies, and configuring the ASC connectors. It is essential to ensure that all of the foundational controls are enabled and configured correctly, as these are the controls that will have the most significant impact on the Secure Score.
3. Implementing Azure Security Center Recommendations
ASC provides a set of recommendations for improving an organization’s security posture. These recommendations are based on the security controls that are enabled and configured correctly, as well as the organization’s overall security posture. It is essential to implement these recommendations as soon as possible, as they will have a direct impact on the Secure Score.
4. Continuously Monitoring Azure Security Center Alerts
ASC generates alerts when it detects potential security threats. It is essential to continuously monitor these alerts and take appropriate action to address them. This can include investigating the alert, implementing a security control, or creating a security incident response plan. By addressing alerts in a timely manner, organizations can improve their overall security posture and maintain a high Secure Score.
5. Regularly Reviewing and Updating Azure Security Center Policies
ASC policies are an essential part of maintaining a high Secure Score. These policies define the security controls that are enabled and configured correctly, as well as the organization’s overall security posture. It is essential to regularly review and update these policies to ensure they are up-to-date and aligned with the latest security best practices. It is also essential to ensure that all security controls and recommendations are met.
