QPR ProcessAnalyzer Security Hardening

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

System Hardening

Disable SSL, TLS 1.0 and TLS 1.1, Ensure TLS 1.2 Enabled

Transport Layer Security (TLS) is used to encrypt connections with clients, such as web browsers. SSL 2.0, SSL 3.0, TLS 1.0 and TLS 1.1 are no longer adequately secure, so we recommend to only allow clients to connect with TLS 1.2. However, some client devices might not support TLS 1.2, so you might need to keep TLS 1.0 and/or TLS 1.1 enabled.

Here is a Powershell script example to disable TLS 1.0 and TLS 1.1 and enable TLS 1.2:

#Disable TLS 1.0 and TLS 1.1
New-Item -Path "HKLM:\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.0\Client\" -Force
Set-ItemProperty -Path "HKLM:\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.0\Client\" -Name Enabled -Type Dword -Value 0
New-Item -Path "HKLM:\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.0\Server\" -Force
Set-ItemProperty -Path "HKLM:\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.0\Server\" -Name Enabled -Type Dword -Value 0
New-Item -Path "HKLM:\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1\Client\" -Force
Set-ItemProperty -Path "HKLM:\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1\Client\" -Name DisabledByDefault -Type Dword -Value 1
New-Item -Path "HKLM:\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1\Server\" -Force
Set-ItemProperty -Path "HKLM:\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1\Server\" -Name DisabledByDefault -Type Dword -Value 1

#Enable TLS 1.2
New-Item -Path "HKLM:\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client\" -Force
Set-ItemProperty -Path "HKLM:\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client\" -Name DisabledByDefault -Type Dword -Value 0
Set-ItemProperty -Path "HKLM:\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client\" -Name Enabled -Type Dword -Value 1
New-Item -Path "HKLM:\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Server\" -Force
Set-ItemProperty -Path "HKLM:\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Server\" -Name DisabledByDefault -Type Dword -Value 0
Set-ItemProperty -Path "HKLM:\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Server\" -Name Enabled -Type Dword -Value 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.

Here is an example of Powershell script to disable 3DES cipher suite:

#Disable Weak Ciphers
New-Item -path "HKLM:\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Ciphers\Triple DES 168" -Force
Set-ItemProperty  -path "HKLM:\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Ciphers\Triple DES 168" -Name Enabled -Type Dword -Value 0

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.

Here is an example of Powershell script to disable 8.3 File Name Creation:

#Disable 8.3 File Name Creation
Set-ItemProperty -Path HKLM:\SYSTEM\CurrentControlSet\Control\FileSystem -Name NtfsDisable8dot3NameCreation -Value 1

Check That Latest Java is Installed

Check that the latest version of Java 8 is installed.

IIS Hardening

Add X-XSS-Protection, X-Frame-Options, and X-Content-Type-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
3. Finally add also:
   • Name: X-Content-Type-Options
   • Value: nosniff

Here is an example of Powershell script to add X-XSS-Protection, X-Frame-Options, and X-Content-Type-Options HTTP Response Headers:

#Add X-XSS-Protection, X-Frame-Options, and X-Content-Type-Options HTTP Response Headers to IIS
Add-WebConfigurationProperty -pspath 'MACHINE/WEBROOT/APPHOST/Default Web Site/ui'  -filter "system.webServer/httpProtocol/customHeaders" -name "." -value @{name='X-XSS-Protection';value='1; mode=block'}
Add-WebConfigurationProperty -pspath 'MACHINE/WEBROOT/APPHOST/Default Web Site/ui'  -filter "system.webServer/httpProtocol/customHeaders" -name "." -value @{name='X-Frame-Options';value='deny'}
Add-WebConfigurationProperty -pspath 'MACHINE/WEBROOT/APPHOST/Default Web Site/ui'  -filter "system.webServer/httpProtocol/customHeaders" -name "." -value @{name='X-Content-Type-Options';value='nosniff'}

• https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Frame-Options
• https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Content-Type-Options

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.

Here is an example of Powershell script to remove X-Powered-By HTTP Response Header:

#Remove X-Powered-By HTTP Response Header in IIS
Remove-WebConfigurationProperty  -pspath 'MACHINE/WEBROOT/APPHOST/Default Web Site/ui'  -filter "system.webServer/httpProtocol/customHeaders" -name "." -AtElement @{name='X-Powered-By'}

Glassfish Hardening

Change Glassfish Administrator Password

Change GlassFish administrator password.

Here is an example of Powershell script to change Glassfish Administrator password:

#Change Glassfish Administrator Password (CMD popup will ask for password. Default glassfish admin credentials: admin/admin)
Start-Process -FilePath "C:\Program Files\QPR Software Plc\QPR UI\Glassfish\bin\asadmin" -ArgumentList "change-admin-password" -Wait
Start-Process -FilePath "C:\Program Files\QPR Software Plc\QPR UI\Glassfish\bin\asadmin" -ArgumentList 'set configs.config.server-config.http-service.virtual-server.server.property.errorReportValve=""' -Wait

Allow Incoming Requests only from Localhost

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

Remove server information from Response Headers

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="".
