The main design decisions are:
Access to MQSeries queues is protected by Access Manager for Business
Integration using the Access Manager authorization engine. Certificates of
internal users are also stored in the IPlanet directory.
Messages between the intranet and internal production network are
encrypted by Access Manager for Business Integration.
Access to Siebel applications is protected by WebSEAL. Additionally
WebSEAL is configured to provide single sign-on. Internet users and internal
users need only a single user ID and password to access applications in
ABBC’s production environment.
Different authentication methods are supported by WebSEAL. Among others,
digital certificates can be used to authenticate users. Certificates are stored in
the IPlanet Directory. An external certificate authority (CA) is not involved. Up
to now, only representatives of ABBC are required to have a certificate.
