Security Center:Overview

Last Updated:Mar 14, 2024

Security Center displays the security operations information about your cloud assets, which can help you monitor the security of your cloud assets. The information includes the status of the cloud assets, security evaluation results, and real-time monitoring and alerting data on various security events. This topic describes how to view the security overview in the Security Center console.

Overview page

The Overview page displays the security data of cloud assets from various dimensions, including the security score, security risk overview, security operations trend, and asset information overview. Security Center also provides entry points to upgrades, renewal, and asset quota increase. This allows you to manage cloud assets in a centralized manner.

Page introduction

Log on to the Security Center console. The Overview page appears by default. You can click the Overview tab to view the security information about your cloud assets.

Description

Secure Score (marked 1 in the preceding figure)

Secure Score displays the security score of your assets. The security score is calculated based on the deduction items such as alerts and configuration risks. The security score ranges from 0 to 100. A higher score indicates fewer risks in your assets. The following list describes how the security score is calculated:

  • If the security score is greater than 60 after penalty points are endorsed but unhandled alerts are detected, the final score is still 60.

  • If the security score is greater than 80 after penalty points are endorsed but unhandled alerts or vulnerabilities are detected, the final score is still 80.

  • If the security score is greater than 90 after penalty points are endorsed but unhandled baseline risks are detected, the final score is still 90.

To improve the security of your cloud assets, you must handle alerts at the earliest opportunity. This helps improve the security score. For more information, see Improve the security score.

Help Center (marked 6 in the preceding figure)

This section displays the links to Security Center documentation. You can click a link to view details.

Improve the security score

The risks of cloud assets are classified into the following levels based on the security score: High risk (below 69), Medium risk (70 to 84), Risks (85 to 94), and Security (95 to 100). We recommend that you handle risks and alerts at the earliest opportunity to improve the security score. This helps ensure the security of your cloud assets.

  1. In the Secure Score section, click Process Now.

  2. In the Security Risk panel, view the penalty point for each risk item. If you want to handle a risk item, you can click Process Now to the right of the risk item to go to the page on which you can view the risk item. You can handle the risk item based on the risk details or the solutions that are provided on the page.

    The Security Risk panel displays the following types of risks that you must handle at the earliest opportunity:

    Note

    The risks displayed in the panel vary based on the edition of Security Center because different editions support different features that are used to detect risks.

Custom security score

By default, Security Center specifies a penalty point for each deduction item. You can customize the penalty points based on your business requirements.

  1. In the upper-right corner of the Secure Score section, click Custom Security Score.

  2. In the Custom Security Score panel, specify a penalty point for each deduction item and click OK.

    • The security score feature supports deduction modules such as Key function configure, Unhandled Alerts, and Unfixed Vul. The deduction threshold of each deduction module ranges from 0 to 100. The sum of the deduction thresholds of all deduction modules cannot exceed 100.

    • Each deduction module contains different deduction items. The penalty point of each deduction item ranges from 0 to the deduction threshold of the deduction module to which the deduction item belongs. The sum of penalty points of all deduction items in a deduction module cannot exceed the deduction threshold of the deduction module.

    Note

    If you have modified the security score settings, Restore to Default Settings is displayed in the Custom Security Score panel. You can click Restore to Default Settings to restore default settings.

FAQ

How do I view the version of the virus library of Security Center?

The update time of the virus library that is displayed in the Security Center console indicates the version of the virus library. You can view the update time of the virus library on the Overview page.

image.png

Security Center dynamically updates the virus library and the characteristics of viruses in the virus library based on the analysis results of engines. The engines include lexical analysis engines, virus detection engines, machine learning engines, deep learning engines, big data-based threat detection engines, threat intelligence engines, and abnormal behavior analysis engines. We recommend that you use Security Center to scan for vulnerabilities and viruses on a regular basis to protect your servers from viruses. For more information, see Scan for vulnerabilities and Use the virus detection and removal feature.

After I install the Security Center agent on my ECS instances, will the virus library of Security Center be installed on the instances?

No,

Security Center does not install the virus library on your Elastic Compute Service (ECS) instances or download the virus library to your ECS instances. The virus library is stored on and is updated by Security Center. Security Center updates the virus library in real time. Security Center checks whether your ECS instances are exposed to viruses based on the virus library.

What are the priorities to handle security events that I can access in the Secure Score section?

The following table describes the priorities to handle security events that you can access in the Security Score section. A smaller number indicates a higher priority. The number 1 indicates the highest priority.

How does the vulnerability scan level affect the security score?

If you focus only on high- and medium-level vulnerabilities and ignore low-level vulnerabilities, you can exclude the low-level vulnerabilities from the scope of the security score.

To exclude low-level vulnerabilities from the scope of the security score, perform the following operations: In the left-side navigation pane of the Security Center console, choose Risk Governance > Vulnerabilities. In the upper-right corner of the Vulnerabilities page, click Settings. In the Settings panel, configure the Vul scan level parameter. For more information, see Scan for vulnerabilities.

How does the baseline check level affect the security score?

If you focus only on high- and medium-level baseline checks and ignore low-level baseline checks, you can exclude the low-level baseline checks from the scope of the security score.

To exclude low-level baseline checks from the scope of the security score, perform the following operations: In the left-side navigation pane of the Security Center console, choose Risk Governance > Baseline Check. In the upper-right corner of the Baseline Check page, click Policy Management. In the Policy Management panel, configure the Baseline Check Item Level parameter. For more information, see Baseline check.
