Vulnerabilities findings

Security Health Analytics and Web Security Scanner detectors generate vulnerabilities findings that are available in Security Command Center. Your ability to view and edit findings is determined by the Identity and Access Management (IAM) roles and permissions you are assigned. For more information about IAM roles in Security Command Center, see Access control.

Detectors and compliance

This section describes the mapping between supported detectors and the best effort mapping to relevant compliance standards.

CIS Benchmarks

Security Command Center supports two versions of the CIS Benchmarks for Google Cloud Platform Foundation:

• CIS Google Cloud Computing Foundations Benchmark v1.1.0 (CIS Google Cloud Foundation 1.1)
• CIS Google Cloud Computing Foundations Benchmark v1.0.0 (CIS Google Cloud Foundation 1.0)

The CIS Google Cloud Foundation 1.1 and 1.0 mappings have been reviewed and certified by the Center for Internet Security for alignment with CIS Google Cloud Computing Foundations Benchmark v1.1.0 and v1.0.0, respectively.

While both CIS 1.1 and CIS 1.0 are supported, we recommend that you use or transition to CIS 1.1, if possible. CIS 1.1 expands coverage to additional Google Cloud services and refines instructions and guidance for complex benchmarks.

Additional standards

Additional compliance mappings are included for reference and are not provided or reviewed by the Payment Card Industry Data Security Standard or the OWASP Foundation. You should refer to Payment Card Industry Data Security Standard 3.2.1 (PCI-DSS v3.2.1), OWASP Top Ten, National Institute of Standards and Technology 800-53 (NIST 800-53), and International Organization for Standardization 27001 (ISO 27001) for how to check for these violations manually.

This functionality is only intended for you to monitor for compliance controls violations. The mappings are not provided for use as the basis of, or as a substitute for, the audit, certification, or report of compliance of your products or services with any regulatory or industry benchmarks or standards.

For instructions on viewing and exporting compliance reports, see the Compliance section in Using the Security Command Center dashboard.

Security Health Analytics

Security Health Analytics detectors monitor a subset of resources from Cloud Asset Inventory (CAI), receiving notifications of resource and Identity and Access Management (IAM) policy changes. Some detectors retrieve data by directly calling Google Cloud APIs, as indicated in tables later on this page.

Security Health Analytics scans run in three modes:

• Batch scan: All detectors are scheduled to run for all enrolled organizations two or more times a day. Detectors run on different schedules to meet specific service level objectives (SLO). To meet 12- and 24-hour SLOs, detectors run batch scans every six hours or 12 hours, respectively. Resource and policy changes that occur in between batch scans are not immediately captured and are applied in the next batch scan. Note: Batch scan schedules are performance objectives, not service guarantees.

• Real-time scan: Supported detectors start scans whenever CAI reports a change in an asset's configuration. Findings are immediately written to Security Command Center.

• Mixed-mode: Some detectors that support real-time scans might not detect changes in real time in all supported assets. In those cases, configuration changes for some assets are captured immediately and others are captured in batch scans. Exceptions are noted in the tables on this page.

The following tables describe Security Health Analytics detectors, the assets and compliance standards they support, the settings they use for scans, and the finding types they generate. You can filter findings by detector name and finding type using the Security Command Center Vulnerabilities tab in the Google Cloud Console.

For instructions on fixing issues and protecting your resources, see Remediating Security Health Analytics findings.

Note: Not all detectors are enabled by default. To turn on inactive detectors, see Enable and disable detectors.

VM Manager

VM Manager is a suite of tools that can be used to manage operating systems for large virtual machine (VM) fleets running Windows and Linux on Compute Engine.

If you enable VM Manager and are subscribed to Security Command Center Premium, VM Manager writes findings from its vulnerability reports, which are in preview, to Security Command Center. The reports identify vulnerabilities in operating systems installed on VMs, including Common Vulnerabilities and Exposures (CVEs).

Vulnerability reports are not available for Security Command Center Standard.

Findings simplify the process of using VM Manager's Patch Compliance feature, which is in preview. The feature lets you conduct patch management at the organization level across all of your projects. Currently, VM Manager supports patch management at the single project level.

VM Manager findings

Preview

This feature is covered by the Pre-GA Offerings Terms of the Google Cloud Terms of Service. Pre-GA features may have limited support, and changes to pre-GA features may not be compatible with other pre-GA versions. For more information, see the launch stage descriptions.

Vulnerabilities of this type all relate to installed operating system packages in supported Compute Engine VMs.

Assets excluded from scans: SUSE Linux Enterprise Server (SLES), Windows operating systems Findings appear in Security Command Center shortly after vulnerabilities are detected. Vulnerability reports in VM Manager are generated as follows: For most vulnerabilities in the installed OS package, the OS Config API generates a vulnerability report within a few minutes of the change. For CVEs, the OS Config API generates the vulnerability report within three to four hours after the CVE is published to the OS.
