Abstract
This chapter addresses the vital “four Ss” for maintaining a successful corporate portal—security, scalability, synchrony, and speed. Security is paramount and the need for robust, fail-safe security measures to safeguard portal resources and the other information technology (IT) systems accessible from the portal is obvious and inescapable. Synchrony refers to the art and science of keeping portal content up-to-date, accurate, coordinated, and linked. Portal speed and scalability, though separate issues, go hand in hand, because they are both influenced by many common factors. Portal speed refers to the response times experienced by end users, while scalability relates to the ability of the portal to grow to accommodate increasing user populations and workloads. Some issues of authentication that pertain to corporate portal security such as digital certificate, public key infrastructure (PKI), secure sockets layer (SSL), intrusion detection, IP Security (IPSec), lightweight directory access protocol (LDAP) directories are also discussed.
