CAUTION: When importing certificates on servers that are not owned by NEOSYS you MUST NOT check the "allow certificate export" option otherwise anybody with access to the server can steal the NEOSYS certificate and pass off their own servers as NEOSYS certified.

NEOSYS has a very simple way of enabling https for all the clients. Every client has been set up with domain name " *.hosts.neosys.com " where "*" is the clientname.


[[image:sslwin2008-1.jpg]]
Pre prepared certificate for *.hosts.neosys.com web sites is present on the nl10r/win3 server. The certificate is signed by COMODO and supports SHA2 security algorithm. It is portable, ensures authenticity and is widely supported. Also refer to [http://itwiki.neosys.com/index.php/SSL_certificate SSL certificate]


If a client's URL is not as per NEOSYS standards, but has been in use for many years, do not change the URL without a good enough reason.


Execute selfssl.exe with the following parameters.

It is especially important to keep pfx files off clients own servers because they are commonly directly exposed to potentially infected employees computers and/or personal devices via the corporate LAN so they may be far less secure than NEOSYS own servers which are reasonably well isolated. If a pfx file is obtained by criminal hackers, perhaps using automated tools, and the pfx password guessed, brute forced, or broken in some way, the keys contained could in principle be used against us or our clients. If the pfx file is a wildcard that supports any subdomain, then loss in one place could affect others. The chances of all this happening is probably very low but NEOSYS needs to be prepared to pass IT audits and leaving keys around will be viewed as having a culture of low security standards.


=== Creating a site in IIS ===
==Setting up HTTPS for installations with more than 1 database==


All clients hosted on NEOSYS servers use the same IP address, but different unique HTTPS port numbers starting from 4431 onwards. Similarly HTTP ports are configured with unique port numbers starting from 8123 onwards. The unique port number should be one greater than the highest port number available on the server under IIS manager -> NEOSYS ->Sites.
In cases where there are multiple databases within the same installation, you can use the same website to access all the databases. In case the Client asks for separate domain names for multiple databases, use the same steps as explained in [[Setting_up_HTTPS#Setting_up_HTTPS_for_NEOSYS_website|Setting up HTTPS]] as the case maybe.


==== Creating a site in IIS in Windows 2008 ====
==Setting up HTTPS for installations where outside office access is usually restricted==


A port binding for HTTP is already created while configuring IIS.
During a new installation, support staff MUST import the certificate to IIS, bind the certificate to NEOSYS website (following the steps mentioned above in [[Setting_up_HTTPS#Creating_a_single_HTTPS_web_site_on_Windows_2008|Creating a single HTTPS web site]]) and test if NEOSYS can be accessed via https on the server (https://localhost:4430), so that no problems are faced in future if the client ever requests for outside access with their management's approval.


Follow the procedures as explained in [http://techwiki.neosys.com/index.php/Setting_up_HTTPS#Creating_a_single_HTTPS_web_site_on_Windows_2008 Creating a Site in Win 2008] and add a port binding for HTTPS.
Since the client management has informed that outside access is not required, close the server's port 4430 (i.e. remove 4430 from Windows Firewall exceptions). Do not remove the certificate binding in IIS.


==== Creating a site in IIS in Windows 2003 ====
If and when https access is required by the client, this can be enabled by unblocking the server's port 4430 and instructing the client to get their IT to configure the router to port forward port 4430 for https.
 
The https options are only available after running selfssl (see below).
 
[[Image:httpadvancedwebsitesetup.png]]
 
=== Testing access to the new HTTPS web site. ===
 
Make a subdomain '''clientname'''.hosts.neosys.com
 
Open "https://'''clientname'''.hosts.neosys.com:44XX/neosys" in IE where 44XX is the designated port number
 
If you get certificate error:
 
#check that the selfsll /n:CN='''clientname'''.hosts.neosys.com matches the domain name used in IE
#install the certificate into the client computer (double click the padlock, view certificates etc)
 
Closing all internet explorer versions and restarting is necessary for installed certificates to become effective.
===Export, Remove and Import Certificates ===
 
This step applies to both Windows 2003 and Windows 2008.
 
The EXPORT/REMOVE/IMPORT stage is necessary where there are multiple https sites on one server since any subsequent SELFCERT seems to destroy all other sites done with SELFCERT that have not been exported/REMOVED/imported.
 
Exporting and Importing certificates in Windows 2008 is just one part of the step to add certificates to sites and you need to follow the usual instructions to "bind" the certificate to a particular site.
 
Certificates must be saved in d:\hosts\certificates preferably by name for easy reference otherwise by site number. If this is not done then if certificates need to be regenerated then you have the pain of supporting re-import of certificates by all users.
 
#Export the certificate to a pfx file from IIS Manager > Click on Server Certificate > Export (to d:\hosts\certificates  - password to be set is in a text file in the same folder)
#Remove the certificate from IIS Manager
#Import pfx certificate back to IIS Manager
#*Use PASSWORD found in certificates folder
#*Make sure you select the "mark certificate as exportable" option <br>[[image:import-export.jpg]]<br>
 
==Setting up HTTPS for installations with more than 1 database==
 
In cases where there are multiple databases within the same installation, the website can be made accessible via different URLs, one for each database, like database1.hosts.neosys.com and database2.hosts.neosys.com, though they will finally be pointing to the same website. In order to assign multiple URLs to the same website, simply repeat the steps for Creating a Single website in [http://techwiki.neosys.com/index.php/Setting_up_HTTPS#Creating_a_single_HTTPS_web_site_on_Windows_2003 Windows 2003] or [http://techwiki.neosys.com/index.php/Setting_up_HTTPS#Creating_a_single_HTTPS_web_site_on_Windows_2008 Windows 2008] for each HTTPS URL that is required.

Setting up HTTPS for NEOSYS website

CAUTION: When importing certificates on servers that are not owned by NEOSYS you MUST NOT check the "allow certificate export" option otherwise anybody with access to the server can steal the NEOSYS certificate and pass off their own servers as NEOSYS certified.

NEOSYS has a very simple way of enabling https for all the clients. Every client has been set up with domain name " *.hosts.neosys.com " where "*" is the clientname.

Pre prepared certificate for *.hosts.neosys.com web sites is present on the nl10r/win3 server. The certificate is signed by COMODO and supports SHA2 security algorithm. It is portable, ensures authenticity and is widely supported. Also refer to SSL certificate

If a client's URL is not as per NEOSYS standards, but has been in use for many years, do not change the URL without a good enough reason.

Creating a single HTTPS web site on Windows 2008

To create a single HTTPS web site on Windows 2008, follow three simple steps:

  1. Copy the "*.hosts.neosys.com.pfx" certificate saved in d:\hosts\certificates on win3 to the server (password to be used is present in a text file in the same folder).
  2. Import the certificate to IIS without option to export and MUST be deleted after import. See Importing certificate in IIS for details.
  3. Click on Sites > Client Web Site > Bindings. In the Bindings section - click on Add and select https, All Unassigned IP addresses, port 4430 and select the certificate from the drop down and click OK.

Test the site from explorer to make sure it works.

Creating a single HTTPS web site on Windows 2003

  • Copy the "*.hosts.neosys.com.pfx" certificate saved in d:\hosts\certificates on win3 to the server. (password to be used is present in a text file in the same folder)
  • Click on Sites > Properties > Directory Security > Server certificate. Follow the steps in the wizard to import/bind the certificate to port 4430. See Installing imported certificate in Windows 2003 IIS for detailed steps to import.

Creating multiple HTTPS web sites on NEOSYS hosted server

All clients hosted on NEOSYS servers use the same IP address but unique HTTPS port numbers starting from 4431 onwards. The unique port number should be one greater than the highest port number available on the server under IIS manager -> NEOSYS ->Sites.

  • Click on Sites > Client Web Site > Bindings. In the Bindings section - click on Add and select https, All Unassigned IP addresses, port 4430 and select the "*.hosts.neosys.com.pfx" certificate from the drop down and click OK.

Since the http access is not required for any Client on NEOSYS hosted server, this step of https binding can be performed while creating the client website as shown in the screen shot below.

Steps to follow while importing certificate and why

  1. It MUST be imported WITHOUT OPTION TO EXPORT and
  2. It MUST be deleted after import.

It is especially important to keep pfx files off clients own servers because they are commonly directly exposed to potentially infected employees computers and/or personal devices via the corporate LAN so they may be far less secure than NEOSYS own servers which are reasonably well isolated. If a pfx file is obtained by criminal hackers, perhaps using automated tools, and the pfx password guessed, brute forced, or broken in some way, the keys contained could in principle be used against us or our clients. If the pfx file is a wildcard that supports any subdomain, then loss in one place could affect others. The chances of all this happening is probably very low but NEOSYS needs to be prepared to pass IT audits and leaving keys around will be viewed as having a culture of low security standards.

Setting up HTTPS for installations with more than 1 database

In cases where there are multiple databases within the same installation, you can use the same website to access all the databases. In case the Client asks for separate domain names for multiple databases, use the same steps as explained in Setting up HTTPS as the case maybe.

Setting up HTTPS for installations where outside office access is usually restricted

During a new installation, support staff MUST import the certificate to IIS, bind the certificate to NEOSYS website (following the steps mentioned above in Creating a single HTTPS web site) and test if NEOSYS can be accessed via https on the server (https://localhost:4430), so that no problems are faced in future if the client ever requests for outside access with their management's approval.

Since the client management has informed that outside access is not required, close the server's port 4430 (i.e. remove 4430 from Windows Firewall exceptions). Do not remove the certificate binding in IIS.

If and when https access is required by the client, this can be enabled by unblocking the server's port 4430 and instructing the client to get their IT to configure the router to port forward port 4430 for https.

A specified logon  session does not exist. It may already have been terminated.

If importing a certificate ONCE at the top level onto a NEOSYS controlled server with multiple web sites then you need to mark the "Allow this key to be exported" checkbox when importing the certificate to IIS.
