Carbon Black Cloud Workload User Guide for vSphere admins

Carbon Black Cloud Workload Overview

VMware Carbon Black Cloud Workload Protection provides vulnerability assessment and inventory management for workloads hosted on vSphere. The VMware Carbon Black Cloud Workload Protection vulnerability solution provides shared information on vulnerabilities that is available in Carbon Black Cloud as well as in the native vCenter administration client.

 

Prevention and threat hunting capabilities can be extended beyond vSphere workloads to your endpoints (desktops, laptops, servers, VMs, etc.).

This document provides the vSphere administrator with a foundational body of knowledge concerning the Carbon Black Cloud Workload Plug-in and how it is utilized in the overall Carbon Black Cloud Workload Protection architecture.

Section 1: Introduction to Cloud Workload Protection

VMware Carbon Black Cloud Workload Protection provides vulnerability assessment and inventory management for workloads hosted on vSphere. The VMware Carbon Black Cloud Workload Protection vulnerability solution provides shared information on vulnerabilities that is available in Carbon Black Cloud as well as in the native vCenter administration client. Workload protection capabilities are fully integrated into the world’s leading cloud management platform for complete data center visibility and protection. The solution combines vSphere and VMware Carbon Black Cloud in a purpose-built, operationally simple solution with minimal overhead and performance impact.

VMware Carbon Black Cloud Workload Protection solution is the only vSphere vCenter workload protection platform for enterprise virtualization and security teams that delivers the most secure virtual infrastructure, while also providing the same visibility and capabilities within the public cloud as well.

The Carbon Black Cloud Workload Protection solution reduces the attack surface by giving Infrastructure, DevOps, and Security teams visibility into the operating system and application vulnerabilities right from within the vCenter Management plane as well as within the Carbon Black Cloud Management Console.

Cloud Workload Protection Architecture

A Carbon Black plug-in within vCenter allows for a shared truth on vulnerabilities and risk for those residing in vSphere/infrastructure as well as team members more focused on security or the Carbon Black Cloud console. Through this unique approach, we can eliminate the trade-off between security and operational simplicity by providing a single source of truth for Infrastructure and Security teams to accelerate response to critical vulnerabilities and attacks, while enabling collaboration and reducing friction. The Carbon Black Cloud Workload Plug-in provides deep visibility into your data center inventory and end-to-end life-cycle management for the components.

VMware Carbon Black Cloud Workload Protection contains two Carbon Black Cloud Workload Protection components:

  • Carbon Black Cloud Workload Protection Plug-in in vCenter
  • Carbon Black Cloud Management Console

Vulnerabilities Tab

The Vulnerabilities page displays vulnerabilities present in your vSphere environment. Click "Vulnerabilities" to navigate the vulnerability page.

An overview of vulnerabilities is shown at the top of the page - including filters based on vulnerability severity. Severity scoring allows for administrators to understand and mitigate risks in a prioritized, realistic method. Higher severity scores indicate that the vulnerability should be prioritized. There are four severity categories… 

  • Low: Score from 0.0 – 3.9 
  • Moderate: Score from 4.0 – 6.9 
  • Important: Score from 7.0 – 8.9 
  • Critical: Score from 9.0 – 10.0

As a vCenter Server administrator, you want to have visibility of known vulnerabilities in your environment to understand your security posture and schedule maintenance windows for patching and remediation. With the help of vulnerability assessment, you can proactively minimize the risk in your environment. 

Vulnerabilities can be viewed in Asset View or Vulnerability View:

  • Asset View displays workloads covered by CWP and allows you to look at all vulnerabilities affecting the workload of interest. 
  • Vulnerability View displays all vulnerabilities based on type (Windows OS, Windows App, etc.).

Carbon Black investigates vulnerabilities related to:

  • Operating System (OS) of the virtual machine.
    • Windows OS: Displays OS-level vulnerabilities for Windows VMs. The system looks for OS details and the security patches applied on each VM. When the security patch associated with the vulnerability is not applied, the VM is flagged as vulnerable.
    • Linux OS: Displays OS-level vulnerabilities for Linux VMs. The system looks for OS details with the list of all installed packages. The system determines the vulnerable packages installed on the VM and reports the CVEs against those packages.
  • Applications are installed on the virtual machine.
    • Windows Apps: Displays application-level vulnerabilities for the Windows VMs.
    • Linux Apps: Displays application-level vulnerabilities for the Linux VMs.

Inventory Tab

The Inventory page displays workloads for which you have enabled and not enabled CWP. You can manage workloads from this page. 

CWP provides a streamlined sensor deployment process. The Carbon Black sensor installer is provided as part of the VMware Tools package. Deployment to workloads is simplified to a ‘click to enable’ process. Simply select the workload for which you would like to enable CWP and click ‘Enable’. Initial assessment begins within 24 hours of enabling, and then occurs daily, automatically from that point forward.

Major sensor updates can be pushed by selecting workload(s) and clicking the ‘Update’ button. Only major sensor updates need to be manually done from the vCenter plugin or Carbon Black Cloud console. Updates can be done individually or on multiple/all workloads.

How Carbon Black Measures Risk

Carbon Black Cloud partners with Kenna Security to leverage the largest database of vulnerability, exploit, and event threat data in the industry. This data is distilled into three main measures of risk:

  • Active Internet Breach: Presence of near-real-time exploitation.
  • Malware Exploitable: Availability of an exploit module in a weaponized exploit kit.
  • Easily Exploitable: Availability of a recorded exploit.

There are metrics defined for Common Vulnerability Scoring System (CVSS). A few of the metrics are about the attack method itself, whereas the others depend on how the application assesses impact - the direct consequence of a successful exploit. To learn more about CVSS, visit https://www.first.org/cvss/specification-document.

Risk Score

Every vulnerability is assigned a risk score of between 0.0 (no risk) and 10.0 (maximum risk). The risk score range and severity are defined as follows.

Score Range

Severity

0.0–3.9

Low

4.0–6.9

Moderate

7.0–8.9

Important

9.0–10.0

Critical

To learn more about how the risk is calculated, refer to the Kenna Security documentation available at https://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/docs/vmwcb-whitepaper-understanding-the-kenna-security-vulnerability-risk-score.pdf.

 

 

Section 3: Identifying Risks with vCenter Carbon Black Cloud Workload Plug-in

VMware Carbon Black Cloud Workload Protection consolidates multiple datacenter security capabilities with an easy deployment experience on vSphere and a single lightweight sensor used throughout your workload environment. VMware Tools includes the Carbon Black sensor installer, facilitating the installation process and eliminating management by providing native security capabilities as a service that IT infrastructure owners can provide. 

Workload protection allows us to discover and view any risks that have been identified by our vulnerability assessment capability. With this capability there is no scanning involved because we are already collecting the data, we are leveraging the same single data stream to query and populate this data within the vCenter management plane.

Looking into a Critical Vulnerability

While logged into vCenter, click on the Menu button at the top of vCenter and then navigate to and click on the Carbon Black plug-in. For more information on accessing and navigating the plug-in see section 2.2.

Navigate to the Vulnerabilities page within the plugin. The Vulnerabilities page displays information on vulnerabilities affecting the environment with intuitive filtering capabilities to give administrators a prioritized, realistic method to look at risk and threat.
