## Impact

This rule identifies GCP Vertex AI Workbench user-managed notebooks that have Integrity monitoring disabled.

Integrity Monitoring continuously monitors the boot integrity, kernel integrity, and persistent data integrity of the underlying VM of the shielded user-managed notebooks. It detects unauthorized modifications or tampering, enhancing security by verifying the trusted state of VM components throughout their lifecycle. It provides active alerting allowing administrators to respond to integrity failures and prevent compromised nodes from being deployed into the cluster.

It is recommended to enable integrity monitoring for user-managed notebooks to detect and mitigate advanced threats like rootkits and bootkit malware.

## How to Fix

## Ensure that integrity monitoring is enabled for your Shielded Vertex AI Notebook Instances by setting the `enable_integrity_monitoring` argument to `true` in your Terraform configuration. This setting helps improve the security posture of your Notebook Instances by ensuring that the integrity of the instance is monitored. \[source,go]

resource "google\_notebooks\_instance" "example" { ... shielded\_instance\_config {

* enable\_integrity\_monitoring = false } }

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/appsec-rules/iac-security/ai-and-machine-learning/appsec-gcp-127.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
