This article provides recommendations for improving (hardening) the security of QPR ProcessAnalyzer Server installation. In addition to the server hardening, there are also hardening instructions for [[QPR_ProcessAnalyzer_ScriptLauncher#Hardening_ScriptLauncher_Security|QPR ScriptLauncher]] installations.


== Add X-XSS-Protection and X-Frame-Options HTTP Response Headers to IIS ==
== Disable SSL, TLS 1.0 and TLS 1.1 ==
This step applies only when [[Routing_Through_IIS_in_QPR_UI|traffic is routed through IIS]].
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 it's recommended to only allow clients to connect with TLS 1.2 or TLS 1.3 (preferred). 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.
# 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'''
# Similarly, add the following HTTP Response Header:
#* Name: '''X-Frame-Options'''
#* Value: '''deny'''

== Remove X-Powered-By HTTP Response Header in IIS ==
<pre>
This step applies only when [[Routing_Through_IIS_in_QPR_UI|traffic is routed through IIS]].
New-Item -Path "HKLM:\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.0\Client\" -Force

New-Item -Path "HKLM:\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.0\Server\" -Force
# Click on the '''X-Powered-By''' header
Set-ItemProperty -Path "HKLM:\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.0\Server\" -Name Enabled -Type Dword -Value 0
# Click '''Remove''' on the right side pane to remove it from the response.

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.
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
</pre>


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.

While it's easiest to run QPR ProcessAnalyzer with a database user assigned the [https://docs.microsoft.com/en-us/sql/relational-databases/security/authentication-access/database-level-roles?view=sql-server-ver15 db_owner] permissions, it's more safe to restrict the database permissions only to needed. The minimum permissions for QPR ProcessAnalyzer are the following:
In GlassFish allow incoming requests only from localhost.
* db_datareader fixed database role
* db_datawriter fixed database role
* user defined role with the following permissions:
** VIEW DATABASE STATE
** EXECUTE on TYPE::PA_TABLETYPE_BigInt
** EXECUTE on TYPE::PA_TABLETYPE_NVarCharMax
** ALTER
** REFERENCES


== Change Glassfish Administrator Password==
Configure QPR ProcessAnalyzer to run with minimum permissions as follows:
Change [[GlassFish Configuration in QPR UI#Changing Glassfish Administrator Password|GlassFish administrator password]].

This article provides recommendations for improving (hardening) the security of QPR ProcessAnalyzer Server installation. In addition to the server hardening, there are also hardening instructions for QPR ScriptLauncher installations.

Disable SSL, TLS 1.0 and TLS 1.1

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 it's recommended to only allow clients to connect with TLS 1.2 or TLS 1.3 (preferred). 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 to disable TLS 1.0 and TLS 1.1 and enable TLS 1.2:

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

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

Use only cipher suites that are considered secure. The up-to-date information regarding security of specific ciphers can be checked here: https://ciphersuite.info/ (use only the ciphers that are classified as recommended or secure). The up-to-date list of the recommended ciphers (maintained by Mozilla) are also available as json format: https://ssl-config.mozilla.org/guidelines/5.6.json (use only the ciphers in the modern and intermediate sections).

Database User Least Privileges

While it's easiest to run QPR ProcessAnalyzer with a database user assigned the db_owner permissions, it's more safe to restrict the database permissions only to needed. The minimum permissions for QPR ProcessAnalyzer are the following:

  • db_datareader fixed database role
  • db_datawriter fixed database role
  • user defined role with the following permissions:
    • VIEW DATABASE STATE
    • EXECUTE on TYPE::PA_TABLETYPE_BigInt
    • EXECUTE on TYPE::PA_TABLETYPE_NVarCharMax
    • ALTER
    • REFERENCES

Configure QPR ProcessAnalyzer to run with minimum permissions as follows:

  1. In the QPR ProcessAnalyzer database, click Security > Roles > Database Roles > Create Database Role....
  2. Give a name to the role (e.g. AdditionalPermissions) and click OK.
  3. To give permissions to the role, run the following commands:
GRANT VIEW DATABASE STATE to AdditionalPermissions
GRANT EXECUTE on TYPE::PA_TABLETYPE_BigInt to AdditionalPermissions
GRANT EXECUTE on TYPE::PA_TABLETYPE_NVarCharMax to AdditionalPermissions
GRANT ALTER to AdditionalPermissions
GRANT REFERENCES to AdditionalPermissions

4. Assign needed roles to the database user by clicking Security > Users and double click the database user. Go to Membership tab and check that following roles are assigned:

  • db_datareader
  • db_datawrite
  • user defined role created earlier

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 other applications that require 8.3 file names and thus may stop working.

Example Powershell script to disable 8.3 file name creation:

Set-ItemProperty -Path HKLM:\SYSTEM\CurrentControlSet\Control\FileSystem -Name NtfsDisable8dot3NameCreation -Value 1

More information: https://support.microsoft.com/en-us/help/121007/how-to-disable-8-3-file-name-creation-on-ntfs-partitions

White-list allowed source IP addresses

Security can be improved by restricting (white-listing) from which source IP addresses connections to the QPR ProcessAnalyzer UI and API can be established. This restriction is typically set in the firewall which can be part of the network infrastructure or it can be in the server machine. If taking this method into use, considered the effort to maintain the up-to-date list of allowed IP addresses versus the gained benefit of the restriction.

HTTP Response Headers

This chapter contains information about security related HTTP response headers that are added or removed in QPR ProcessAnalyzer. Thus, no actions are required regarding these HTTP response headers.

Added HTTP Headers

Following security related HTTP headers are set:

  1. Content-Security-Policy
    • Name: Content-Security-Policy
    • Value: default-src 'none';script-src 'self' 'unsafe-eval';style-src 'self' 'unsafe-inline';img-src 'self' data: blob:;connect-src 'self';font-src 'self' data:;manifest-src 'self';child-src 'self';frame-src *;
  2. Strict-Transport-Security (Note: HTTPS is required)
    • Name: Strict-Transport-Security
    • Value: max-age=31536000; includeSubDomains
  3. X-Frame-Options:
    • Name: X-Frame-Options
    • Value: sameorigin
  4. X-Content-Type-Options:
    • Name: X-Content-Type-Options
    • Value: nosniff

Removed HTTP Headers

By default, IIS returns the X-Powered-By HTTP response header that has been removed in QPR ProcessAnalyzer. More information: https://blogs.msdn.microsoft.com/varunm/2013/04/23/remove-unwanted-http-response-headers/

By default, IIS 10.0 returns Server header in http response that has been removed in QPR ProcessAnalyzer. More information: https://www.saotn.org/remove-iis-server-version-http-response-header/#removeserverheader-requestfiltering-in-iis-10-0
