QPR ProcessAnalyzer Security Hardening

The following list provides recommendations for improving (hardening) the security of QPR UI installation.

Add X-XSS-Protection and X-Frame-Options HTTP Response Headers to IIS

This step applies only when traffic is routed through IIS.

1. In Internet Information Services (IIS) Console, click ui folder in the left side hierarchy, double-click HTTP Response Headers, click Add... on the right side pane, and define the following:
   • Name: X-XSS-Protection
   • Value: 1; mode=block
2. Similarly, add the following HTTP Response Header:
   • Name: X-Frame-Options
   • Value: deny

Remove X-Powered-By HTTP Response Header in IIS

This step applies only when traffic is routed through IIS.

1. In Internet Information Services (IIS) Console, click ui folder in the left side hierarchy
2. Double-click HTTP Response Headers
3. Click on the X-Powered-By header
4. Click Remove on the right side pane to remove it from the response.

Disable TLS 1.0

Transport Layer Security (TLS) is used to authenticate and encrypt connections with external clients such as browsers. Browsers connect to QPR UI using TLS over HTTPS. TLS is an improved version of SSL (Secure Sockets Layer). Versions of SSL 2.0 and 3.0 are no longer considered to be adequately secure communication standards. We recommend that you only allow external clients to connect with TLS 1.2.

In addition, we recommend that TLS 1.0 and TLS 1.1 are disabled on QPR UI server. However, before you disable a specific version of TLS, verify that the browsers that your users connect to QPR UI support TLS 1.2. You may need to preserve support for TLS 1.1.

Disable Weak Ciphers

The Triple-DES cipher suite is no longer considered adequate to encrypt sessions on the internet. Specifically, running Triple-DES ciphers leaves the server vulnerable to information disclosure and denial of service attacks. You can learn more at the National Vulnerability Database webpage for CVE-2016-2183.

Allow Incoming Requests only from Localhost

This step applies only when traffic is routed through IIS. In GlassFish allow incoming requests only from localhost.

Change Glassfish Administrator Password

Change GlassFish administrator password.

Disable 8.3 File Name Creation

In order to disable short names creation, add a registry key named NtfsDisable8dot3NameCreation to HKLM\SYSTEM\CurrentControlSet\Control\FileSystem and set its value to 1. Note that in the computer, there may be applications that require 8.3 file names and thus may stop working.

Check That Latest Java is Installed

Check that the latest version of Java 8 is installed.

Other Instructions to Hardening GlassFish Security

• The response headers contain some information which should not be disclosed to the public to prevent targeted attacks.

Server: GlassFish Server Open Source Edition 4.1

X-Powered-By: Servlet/3.1 JSP/2.3 (GlassFish Server Open Source Edition 4.1 Java/Oracle Corporation/1.8)

You can disable this by turning off the XPowered By: header with your http-listener and by adding a JVM-Option -Dproduct.name="".

• The application may leak sensitive data via application errors.

Configure the Logger Settings in Glassfish from the GlassFish Administration Console :

1. In the navigation tree, expand the Configurations node.
2. Under the Configurations node, click the server instance or cluster configuration for which you want to configure Logger Settings.
3. The Configuration page opens.
4. On the Configuration page, click Logger Settings.
5. The Logger Settings page for the selected configuration target opens.
6. Select the desired log level
