Original Process

• System based (30 production systems)

• Many visits for the same users

– For each system

– For each role

• Access changes requested and processed manually.

Very Repetitive…

Role 1

Excel Based

• Export role allocations from SAP to Excel

• Add role owner information from SQL

• Add team structure information from HR

• Sent to team leaders by role owners by e-mail

• LAO were taking 3 months to complete a review

How to fix the Audit Finding?

Risk Based Reviews

• Over 30,000 roles globally

• Not all roles need reviewing

• Only review the ‘important’ roles

• Assess risk of each role.

Role Classification

• Role owners often unaware of some of risk

• Wanted a ‘scientific’ approach

• Key transactions

– Critical / Sensitive functions

– Critical authorisation values

– Key business processes

– Contributing to SoD concerns.

Confidential or Internal

• Confidential

– Roles contain important access or could contribute to a segregation of duties concern

– Role allocations must be reviewed.

• Internal

– If role allocations not reviewed, these would not expose Kimberly-Clark to any significant risk.

Use of Virsa

• Assess role contents at role change time

• Technical checks if critical values being introduced

• SoD contributing transactions

• Role classification updated as necessary.

Virsa Process

Assess current risks

in role

Change role contents

Re-Assess to see if risks

have changed

• Internal roles changing their classification

• Confidential roles rarely lose access

• Internal roles won’t be reviewed.

• As part of role change management

Classifications into SAP Role Database

A New Process for Access Reviews

• Fewer roles to review

– Still more than we expected!

• Fewer users to review

– Some only have Internal roles

• Reduced effort to manage review process

• GRC 10.0 didn’t exist in 2009.

Because of our SAP history

• Fire fight and Virsa

• Developed in-house solution

• Caters for some unique K-C issues

• Most cost effective, given planned initiatives.

The SAP Access Review System

• SQL database, with Intranet based pages

• Weekly extracts of data

– SAP (AGR_USERS table)

– active directory

– contractor database and

– Education Management System

• Data in .CSV format, leveraging old process.

A True Team Structure

• Permanent employees

– Based on HR organisation structure

• Contract staff

– Not in HR structure

– Have a K-C sponsor

– Sponsor considered their team leader.

Review History

Delegating the Task

• Team Leaders have the responsibility to ensure their team reviewed

– Can delegate to a member of their team

– Can delegate to a ‘trusted’ third party

– Team leaders can set 2 delegates

• People can request to be a delegate

• Admin can set their delegates to any team.

Reporting – Role Centric View

Orphans

• Team members without a team leader

• Some due to ‘timing’ issues in team structure

• Some truly missing a manager

• Contractors moving teams

• Team leaders leaving.

Orphan User Report

Built-In Help / Tutorial

Some Numbers

• 4,140 Team Leaders

• 35,000 Team Members

• Initially 700+ Orphans!

• Over 500,000 user-role allocations

• 95% completion in active regions.

Chasing Up

• Team leaders responsible for completing reviews

• Regional Internal Controls oversee process

• Some changes needed to system, as not designed to be administer centrally

• Culture change necessary to stop ‘handholding’.

Lessons Learnt

• Organisation data for many teams wrong

• Time wasted on correcting team info, not doing reviews

• Some team leaders would complain longer about doing a review than review took them!

Future Changes

• Workday being rolled out globally

– ‘true Global’ HR system

– K-C employees

– Contract staff

• CA Identity Manager

– Managing user accounts

– SAP role allocations.
