1.0 Introduction
SAP has done nothing less than
change the entire systems landscape for enterprises. The benefits it
can bring have led to widespread adoption across the globe. One of
the key benefits SAP brings to an enterprise is the ability to
integrate the data both within the enterprise, and between it and
it’s partners / competitors. In many cases organizations today are
both partners and competitors at the same time. Think of wholesalers
and distributors, SAP and Oracle, AT&T and BT, or two oil giants who
have an upstream joint venture. These companies use SAP to integrate
process between themselves for their mutual benefit. This ability to
integrate, however, brings with it a particular risk – that of
exposing their data to the un-authorized outside world.
Entire companies have been built
up around highly guarded intellectual property and process secrets
... and could easily fall if this was breached. Therefore, keeping
the security of the organization intact is one of the vital aspects
of any SAP implementation.
SAP BASIS addresses all security
issues by incorporating an authorization module. With increased
potential for security breaches in the computer systems around the
world, BASIS consultants face a tough task of maintaining the
integrity and administering the security of SAP systems.
Interoperability features of a SAP system makes this task a bit more
difficult.
2.0 SAP Security Components – The Big
Picture
SAP security in an integrated
environment can be viewed in the form of discrete components as
shown below (figure 1).

Figure 1
Tight security is required for
each of the above components (Network, Workstation, Operating System
and Database) as a breach made in one area can compromise the entire
system.
The scope of this article is SAP
Application Security, which can be achieved with the help of SAP’s
BASIS security application through the concept of authorization.
In SAP, security is administered for objects
(profiles and authorizations). Users are only authorized to see or
change the parts of the system required by their respective job
responsibilities.
