Dynamics)?
•
How many people actually use SAP?
•
How many people use a GRC tool for Segregation of Duties (SoD) Analysis
– such as SAP GRC, Oracle GRC, or Fastpath?

There are several security related backend tables and configuration that are critical to
maintaining a controlled security environment that are often overlooked or maintained which
could become a significant security risk.

User Provisioning
Key Risks

Documenting appropriate approvals
for compliance purposes
•
Delay in provisioning or deprovisioning
•
Selection of correct roles
•
User access reviews
Root-Causes
•
•
•
•
16
The user does not know the appropriate role to select due to current naming convention
User provisioning is a manual process
Approvals are documented offline or via email
Master data has not been maintained appropriately

User Provisioning
GRC automates the SAP access request and provisioning
process by providing customizable workflow options that
integrate seamlessly with the SoD Risk Analysis
Solution Enhancements
Key Benefits
• User Provisioning:
− Integrates with SAP to prevent
SoD Violations
− Customizable access request
workflows
− Template based access requests
− Complete audit trail to satisfy
compliance requirements
− Eliminates manual provisioning
to end users
• Workflows also available for:
− User Access Reviews
− FF Log Review
− SoD Remediation
− Mitigating Control Assignment /
Review
• Standardized on SAP Business
Workflow Technology
• Business workflow reduces
manual tasks and streamlines
access request processing
• Gain visibility of User Access
Risks before entering a production
environment
• Faster and easier for users to
request the roles they need
• Leverage existing resources for
workflow administration and
configuration
• Utilize existing HR structure for
automated and compliant position
based role assignment
• Improved security and richer
request context

Segregation of Duties (SoD)
Key Risks
•
A user with excessive or sensitive
access within the system has the
ability to perform fraudulent activity
•
Internal controls may be circumvented
by excessive access
Root-Causes
•
•
•
•
18
Over the course of time a user may switch job functions
It may be necessary for the user to have the access within SAP to perform both business
functions during the transition period
After the transition period is over the user may still retain this excessive access
SoD violations can quickly spiral out of control because in some organizations users submit
access requests by replicating a user performing the same job function

SoD / Sensitive Access Monitoring
SoD / Sensitive Access Monitoring
• Products such as SAP Access Control can be used to monitor
SoD Violations, as well as Sensitive Access.
• A custom “rule set” containing function conflicts (e.g., Create
Vendor vs. Manual Payments), as well as sensitive
transactions/objects can be tailored to your specific risk
environment.
• Simulations and “what if” analyses can be run before actual
security changes are made.
• Can be integrated into the user provisioning and role creation
process.

Customizing Your Ruleset
It is import to customize your own ruleset by reviewing with all of
the key stakeholders:
–
Risk Relevance - Inactive vs. active
–
Criticality Level - Low, medium, high, or critical
–
Modify Rules – There are authorizations which need to be
adjusted to ensure accuracy for your organization and to
remove false positives
–
Review Custom Transactions and Tables – All new custom
transactions and programs should be reviewed for inclusion in
the ruleset

Management of Temporary / Emergency Access
Key Risks
•
Superuser or privileged access should
be approved and reviewed in a timely
manner
•
A user can perform critical actions
either accidentally or maliciously to
interrupt system availability
Root-Causes
•
•
•
•
21
Certain sensitive or critical transactions are necessary to keep the system running smoothly
Restricting and monitoring sensitive access within the system is a top audit concern
Log review is a very tedious and time consuming process
Some users are assigned the profile SAP_ALL granting unrestricted access

Management of Temporary / Emergency Access
Emergency Access Management
• SAP Access Control or Firefighter, can be used to effectively handle
temporary and elevated system access.
• All activity and the changes performed within Firefighter are logged for
review/signoff.
• Log review can be integrated into workflow to automatically route and
track Firefighter log approvals.
• Provisioning of Firefighter IDs can be integrated into Access Request
(ARQ).
• Centrally managed across all systems (end-user does not need an ID
in the target system, only the GRC system).

How Firefighter Works?
The workflow functionality within SAP GRC can provide an automated and auditable process for:
–
–
–
–
Requesting elevated access
Routing request for approval
Automatically assigning approved access for the specified time period
Logging and routing the activity logs to the Firefighter Controller for review.
• Reduces the effort required to grant and provision emergency access to multiple systems. Provides a structured,
documented process around emergency access
• Enables documented account of the controller’s review

Control Optimization
•
Sometimes we cannot avoid certain risks within the ERP systems we manage.
•
Luckily, SAP has many configurable controls that can be enabled to help mitigate some of these risks.
•
For example:
–
Check for duplicate invoices
–
