Secure Remote Access
26 Portal Server 6 2005Q1 • Deployment Planning Guide
If the portal does not contain sensitive information (deploying public information
and allowing access to free applications), then responses to access requests by a
large number of users is faster than secure mode.
Figure 1-1 shows Portal Server configured for open mode. In this figure, Portal
Server is installed on a single server behind the firewall. Multiple clients access the
Portal Server system across the Internet through the single firewall, or from a web
proxy server that sits behind a firewall.

Portal Server in Secure Mode
In secure mode, Portal Server is installed with SRA. Secure mode provides users
with secure remote access to required intranet file systems and applications.
NOTE You can provide secure access to users of web-enabled resources by
running Portal Server in open mode with the HTTPS protocol.
However, without SRA, you cannot provide secure remote access to
file systems or TCP/IP applications.
