# Port 22 is exposed misconfiguration detected in code

## Impact

This rule detects whether port 22 is exposed in Dockerfiles. Exposing port 22 in Docker containers poses security risks by potentially allowing unauthorized users to gain SSH access. Therefore, avoid exposing port 22 and use more secure methods for managing and accessing your containers.

## How to Fix

To mitigate this issue, remove any EXPOSE instructions related to port 22. Consider using more secure alternatives to SSH for managing your containers.

## Example: \[source,go]

* EXPOSE 22 + # Do not expose port 22 ...

## 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/public-exposure/appsec-docker-1.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.
