Technical Information
 
Citrix Receiver Client and Your Firewall
Citrix Receiver Client traffic uses the registered port 1494 with the TCP protocol.
Security
 
The information below is a brief description of Northern’s applications' security components. 
Secure Sockets Layer (SSL)
SSL is a protocol for transmitting private data via the Internet. SSL creates an encrypted (128-bit) connection between a client and a server, over which any amount of data can be sent securely. Both Netscape Navigator and Internet Explorer support SSL. Verisign Company, a leading provider of secure Internet communications, verifies the encryption.

 

Citrix Secure Gateway
Secure Gateway manages authentication and authorization and is responsible for creating a secure channel for the Citrix ICA protocol over SSL. With Secure Gateway, the data exchanged between the client device and servers is transmitted over the secure network.

 

Authentication
User authentication is required to gain access to Northern’s production applications. Strong password-complexity policies are implemented for increased customer protection. Transmission of both user IDs and passwords occurs over the secure and encrypted SSL connection.

 

Firewall
A firewall is a system designed to prevent unauthorized access to a private network or to restrict certain types of traffic from being sent via the Internet into a secure area.
All messages entering or leaving the intranet pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria.
Several layers of security are incorporated in the access of Northern's systems over the Internet:
SSL - security during external customer's communication with Northern's systems (128-bit encryption)
Citrix Secure Gateway - a secure channel for Citrix ICA
Citrix ICA (128-bit encryption)
User authentication with the strong password
Limited access through firewall technologies
Windows security
In summary, access to Northern applications over the Web utilizes several levels of security. In view of these considerations, Northern's applications should be considered a secure method for conducting gas pipeline transportation business over the Internet.
