Understanding the Security Score

The Security Score on the Overview page provides a rough estimate of how secure your system is.

  1. From the Cloud Guard options panel on the left, select Overview.
  2. View the Security Score tile in the top-left corner.
    • The numeric security score indicates the percentage of resources that Cloud Guard has examined which it did not flag as potential problems.
    • A higher security score is better. A security score of 100 would mean that no problems were detected for any resources.
    Note

    The security score reflects monitoring for the past 30 days. Cloud Guard updates the security score calculation continuously.

Understanding the Risk Score

The Risk Score on the Overview page provides a rough estimate of the risk level to your environment that's posed by the problems that Cloud Guard detects.

The risk score is related to the number and severity of problems. In general, organizations with many more resources are likely to have more problems, and thus a higher risk scores. The risk score is closely related to the "potential surface area" of risk. If you have many OCI resources, you might have an excellent security score (overall assessment) and still have a higher risk score.

Viewing the Risk Score

  1. From the Cloud Guard options panel on the left, select Overview.
  2. View the Risk Score tile in the top center.

How the Risk Score is Calculated

  • The numeric risk score is updated every 15 minutes, and reflects the total number of problems that Cloud Guard has detected, the risk level of each problem, and the types of resources involved.

    Different categories of resources are more sensitive to security threats and that sensitivity weights the scoring. For example, users (IAM) and buckets are considered more sensitive, based on factors such as how easy they are to access and how they can be used as a target of attack.

  • The raw risk score that’s calculated is normalized to fall within the range of 0-9,999. A risk score of zero would mean that no problems were detected for any resources.

    A high risk score generally means there are a larger number of problems that have higher risk levels (HIGH or CRITICAL). If the problems and the resources involved are less sensitive, a large number of problems doesn’t produce a high risk score.

  • Best practice for security is to give priority to addressing the problems with the highest risk levels, that Cloud Guard detects on the most sensitive resources. Following this best practice also produces the greatest reduction in the risk score.
Note

The risk score reflects monitoring for the past 30 days. Cloud Guard updates the risk score calculation continuously.

Interpreting the Trendline Charts

The trendline charts show the change over time in the Security Score number, the Problems Snapshot total number, and total number reflected in Security Recommendations.

  1. From the Cloud Guard options panel on the left, select Overview.
  2. On the Overview page, scroll to the bottom to view the trendline charts.

    Each trendline chart tracks a number displayed in one of the tiles at the top of the Overview over time:

    • Security Score Trendline - tracks the Security Score number.
    • Problems Trendline - tracks the Total number in the Problems Snapshot tile.
    • Remediation Trendline - tracks the total number of open recommendations you would see if you click View All Recommendations on the Security Recommendations tile.
  3. Click the Start Date and End Date controls to change the time period that's covered.
    The default is the last 30 days.
  4. To see a breakdown of the information going into a data point, move your mouse pointer over that data point in any chart.
  5. In the New Problems Trendline chart, click a data point to view all the new problems for that data point on the Problems page.

Processing Security Recommendations

Follow links from the Security Recommendations tile to implement Cloud Guard recommendations for resolving the highest priority problems that have been detected.

  1. From the Cloud Guard options panel on the left, select Overview.
  2. View the Security Recommendations tile in the top-right corner.

    The Security Recommendations tile provides links to suggestions to improve your security and risk scores. Only the top two are listed in the tile.

  3. Click View Recommendations to see the full list.
    The full list of recommendations is displayed on the Recommendations page.

Processing Problems from the Problems Snapshot

View a breakdown of problems by severity level and drill down to see the list of problems from each severity level on the Problems page.

  1. From the Cloud Guard options panel on the left, select Overview.
  2. View the Problems Snapshot tile, just below the Security Score tile in the top-left corner.

    The Problems Snapshot tile shows the breakdown of detected problems by severity level in a pie chart, with the total number of problems displayed in the center. This chart is updated continuously.

    Cloud Guard categorizes problems by these severity levels;

    • Critical - the most serious problems detected, which should be your highest priority to resolve.
    • High - the next most serious problems.
    • Medium - problems that are a bit less serous.
    • Low - problems that are still less serious.
    • Minor - the least serious problems detected; they still need be resolved eventually, but can be your lowest priority.
  3. To see the number of problems in that severity level, move your mouse pointer over one of the color sections.
  4. Click a color section in the pie chart to open the Problems page, filtered to display the list of problems in that severity level.
