# GCP VPC subnet flow logs should be captured

> Checks that VPC subnet flow logs are enabled in GCP.

Checks that VPC subnet flow logs are enabled in GCP.

## About

When you connect Google Cloud Platform (GCP) to DSALTA, the platform retrieves the list of resources in your environment using read-only API access. DSALTA then checks whether this configuration is in place. If it is not, DSALTA activates this check so you can remediate it.

## Why This Matters

Without audit logs you cannot detect unauthorized activity, investigate an incident, or prove what happened during an audit. Comprehensive, retained logs are the forensic backbone of incident response and are mandated by SOC 2, ISO 27001, and HIPAA.

## How to Fix

**Before you begin**

* Ensure you have the appropriate **admin** role on the project.

**Configure logging**

1. Sign in to the [Google Cloud Console](https://console.cloud.google.com/).
2. For **VPC flow logs**, open **VPC network → Subnets**, edit the subnet, and enable **Flow logs**.
3. For a **log sink**, open **Logging → Log Router → Create sink** and choose a destination (BigQuery, Cloud Storage, or Pub/Sub).
4. Save the configuration.

Once logging is configured, DSALTA retrieves the change on the next sync and sets the check status to **Passing**.

## Frequently Asked Questions

<AccordionGroup>
  <Accordion title="How often does this check run?">
    This check runs automatically every 24 hours while the Google Cloud Platform (GCP) integration is connected. You can also trigger a manual sync from **Integrations** in the sidebar.
  </Accordion>

  <Accordion title="What happens if it keeps failing?">
    A failing check appears in your **Data Library → Tests** dashboard. Work through the steps above; once the underlying configuration is fixed, the status updates automatically on the next sync.
  </Accordion>

  <Accordion title="Can I exclude this check?">
    Yes. If it does not apply to your environment, mark it as **Not Applicable** with a justification. The exclusion is documented for auditors.
  </Accordion>

  <Accordion title="Does DSALTA change my Google Cloud Platform (GCP) configuration?">
    No. DSALTA uses **read-only API access** and never modifies, creates, or deletes resources. All remediation is performed by your team directly in Google Cloud Platform (GCP).
