# 6.4 Ensure secure is set to true only for SSL-enabled Connectors (Automated)

## Profile Applicability

• Level 1

## Description

The `secure` attribute is used to convey Connector security status to applications operating over the Connector. This is typically achieved by calling `request.isSecure()`. Ensure the `secure` attribute is only set to `true` for Connectors operating with the `SSLEnabled` attribute set to `true`.

## Rationale

Accurately reporting the security state of the Connector will help ensure that applications built on Tomcat are not unknowingly relying on security controls that are not in place.

## Audit Procedure

Review the `server.xml` and ensure the secure attribute is set to `true` for those Connectors having `SSLEnabled` set to `true`. Also, ensure the `secure` attribute is set to `false` for those Connectors having `SSLEnabled` set to `false`.

## Remediation

For each Connector defined in `server.xml`, set the `secure` attribute to `true` for those Connectors having `SSLEnabled` set to `true`. Set the `secure` attribute to `false` for those Connectors having `SSLEnabled` set to `false`.

```xml
<Connector SSLEnabled="true"
  …
  secure="true"
  …
/>
…
<Connector SSLEnabled="false"
  …
  secure="false"
  …
/>
```

## Default Value

The `secure` attribute is set to `false`.
