Extranets An extranet is similar to an intranet but it enables the firm’s business partners (e.g., suppliers or customers) to access the firm’s intranet Once an organization links its network to the Internet theoretically anyone can access the firm’s network. With respect to an extranet, firms want to restrict access to business partners. A virtual private network provides the security mechanism for accomplishing this. A VPN uses a combination of public and private lines to build a secure extranet. The link between the firm’s network and the Internet is often called a “tunnel.” A VPN provides a secure tunnel. VPNs are also required for firms with extensive intranets (multi- site firms) 40
