# LDAP is configured to use an unencrypted channel

## Rule Details

| --------------------- | -------------------- |
| Cortex AppSec Rule ID | APPSEC\_CICD\_47     |
| Category              | System Configuration |
| Severity              | MEDIUM               |

## Impact

The LDAP protocol is used in the Jenkins instance for the authentication of users. This instance is communicating with the remote LDAP server over an unencrypted channel. This allows attackers to perform a Man In The Middle attack and intercept the LDAP traffic, which may lead to bypassing the authentication mechanism and gaining control over the Jenkins instance.

## Recommended Solution - Buildtime

Encrypt all LDAP data in transit flowing to and from the Jenkins instance, by using the secure LDAPS protocol.

## 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/ci-cd-security/system-configurations/appsec-cicd-47.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.
