The information below is a brief description of Northern's applications' security components.

Transport Layer Security (TLS)

TLS is a widely adopted security protocol designed to facilitate privacy and data security for communications over the Internet. A primary use case of TLS is encrypting the communication between web applications and servers, such as web browsers loading a website.​


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 TLS connection.​


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:

  • TLS - security during external customer's communication with Northern's systems
  • User authentication with a 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.​
