Providing Secure Access to Information Using the Internet

Historically, TransCanada PipeLines Limited, like most companies, has had a security policy that required its computing infrastructure (networks and computing systems) to be isolated from public networks, including the Internet. The existing infrastructure took advantage of this isolation when it was designed. New business opportunities require TransCanada to open up its computing infrastructure to public networks, particularly the Internet. The security policies have been revised to ensure that, while everyone who has a need to access TransCanada information can do so, individuals who do not have a legitimate reason to see TransCanada information cannot do so.
