# 9.1 Disabling auto deployment of applications (Automated)

## Description

Tomcat allows auto deployment of applications while Tomcat is running. It is recommended that this capability be disabled.

## Rationale

This could allow malicious or untested applications to be deployed and should be disabled.

## Audit Procedure

Perform the following to ensure `autoDeploy` is set to `false`.

```
# grep "autoDeploy" $CATALINA_HOME/conf/server.xml
```

## Remediation

In the `$CATALINA_HOME/conf/server.xml` file, change `autoDeploy` to `false`.

```
autoDeploy="false"
```

## Default Value

`autoDeploy` is set to `true`.
