## Impact

This rule detects whether the Ansible \`dnf\`\` module is used to install packages without GPG signature verification. GPG signatures provide assurance that the packages have not been tampered with, and originate from trusted sources.

## How to Fix

*Module:* dnf

* *Attribute:* disable\_gpg\_check

To mitigate this risk, ensure that the disable\_gpg\_check attribute in your DNF tasks is either set to 'false' or not specified (defaulting to false). This ensures that GPG signature checks are performed, preventing the installation of potentially compromised or untrusted packages.

Secure Code Example:

## In the example above, thedisable\_gpg\_check attribute is explicitly set to false, ensuring that the DNF module verifies GPG signatures, aligning with this rule's requirement for secure package management. \[source,go]

* name: Example ansible.builtin.dnf: name: nginx state: latest disable\_gpg\_check: 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/compute/appsec2-ansible-4.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.
