# CIS Apache Tomcat 7 - 1.1 Remove extraneous files and directories (Scored)

## Profile Applicability

- Level 2

## Description

The installation may provide example applications, documentation, and other directories which may not serve a production use.

## Rationale

Removing sample resources is a defense in depth measure that reduces potential exposures introduced by these resources.

## Impact

Removal of example applications and documentation reduces available attack surface.

## Audit Procedure

Perform the following to determine the existence of extraneous resources:

1. List all files extraneous files. The following should yield no output:

```bash
$ ls -l $CATALINA_HOME/webapps/js-examples \
    $CATALINA_HOME/webapps/servlet-example \
    $CATALINA_HOME/webapps/webdav \
    $CATALINA_HOME/webapps/tomcat-docs \
    $CATALINA_HOME/webapps/balancer \
    $CATALINA_HOME/webapps/ROOT/admin \
    $CATALINA_HOME/webapps/examples \
    $CATALINA_HOME/server/webapps/host-manager \
    $CATALINA_HOME/server/webapps/manager \
    $CATALINA_HOME/conf/Catalina/localhost/host-manager.xml \
    $CATALINA_HOME/conf/Catalina/localhost/manager.xml
```

## Remediation

Perform the following to remove extraneous resources:

1. The following should yield no output:

```bash
$ rm -rf $CATALINA_HOME/webapps/js-examples \
    $CATALINA_HOME/webapps/servlet-example \
    $CATALINA_HOME/webapps/webdav \
    $CATALINA_HOME/webapps/tomcat-docs \
    $CATALINA_HOME/webapps/balancer \
    $CATALINA_HOME/bin/webapps/ROOT/admin \$CATALINA_HOME/webapps/examples
```

If the Manager application is not utilized, also remove the following resources:

```bash
$ rm -rf $CATALINA_HOME/server/webapps/host-manager \
    $CATALINA_HOME/server/webapps/manager \
    $CATALINA_HOME/conf/Catalina/localhost/host-manager.xml \
    $CATALINA_HOME/conf/Catalina/localhost/manager.xml
```

## Default Value

Depending on your install method, default extraneous resources will vary.
