# 10.5 Rename the manager application (Manual)

## Description

The manager application allows administrators to manage Tomcat remotely via a web interface. The manager application should be renamed to make it harder for attackers or automated scripts to locate.

## Rationale

By relocating the manager applications, an attacker will need to guess its location rather than simply navigate to the standard location in order to carry out an attack.

## Audit Procedure

Ensure `$CATALINA_HOME/conf/Catalina/localhost/manager.xml`, `$CATALINA_HOME/webapps/host-manager/manager.xml`, `$CATALINA_HOME/webapps/manager` and `$CATALINA_HOME/webapps/manager` do not exist.

## Remediation

Perform the following to rename the manager application:

1. Rename the manager application XML file:

```
# mv $CATALINA_HOME/webapps/host-manager/manager.xml \
$CATALINA_HOME/webapps/host-manager/<new-name>.xml
```

2. Update the docBase attribute within `$CATALINA_HOME/webapps/host-manager/<new-name>.xml` to `$CATALINA_HOME/webapps/<new-name>`

3. Move `$CATALINA_HOME/webapps/manager` to `$CATALINA_HOME/webapps/<new-name>`

```
# mv $CATALINA_HOME/webapps/manager $CATALINA_HOME/webapps/<new-name>
```

## Default Value

The default name of the manager application is `manager` and is located at:

```
$CATALINA_HOME/webapps/manager
```
