# 10.4 Force SSL when accessing the manager application via HTTP (Manual)

## Description

Use the transport-guarantee attribute to ensure SSL protection when accessing the manager application.

## Rationale

By default when accessing the manager application via HTTP, login information is sent over the wire in plain text. By setting the transport-guarantee within `web.xml`, SSL is enforced.

Note: This requires SSL to be configured.

## Audit Procedure

Ensure `$CATALINA_HOME/webapps/manager/WEB-INF/web.xml` has the `<transport-guarantee>` set to `CONFIDENTIAL`.

```
# grep transport-guarantee $CATALINA_HOME/webapps/manager/WEB-INF/web.xml
```

## Remediation

Set `<transport-guarantee>` to `CONFIDENTIAL` in `$CATALINA_HOME/webapps/manager/WEB-INF/web.xml`:

```xml
<security-constraint>
  <user-data-constraint>
    <transport-guarantee>CONFIDENTIAL</transport-guarantee>
  </user-data-constraint>
</security-constraint>
```

## Default Value

By default this configuration is not present.
