What We’ll Cover

Ogilvy Overview

Ogilvy Overview

In 1948, David Ogilvy found the agency that has since become one of the most prominent

marketing communications brands in the world, Ogilvy. David’s legacy and three core pillars are

something we continue to live by today:

For nearly 70 years, Ogilvy has helped build some of the most valuable and iconic brands in the

world including American Express, Ford, and Dove, and more recently, IBM

1. A focus on the quality and diversity of our people

2. A commitment to quality of service and class of operation, as he often said, “Only first-class business,

and that in a first-class way”

3. A rooted belief in brands; David Ogilvy famously said, "We Sell or Else"

Our work is not just about selling products; it is more importantly about helping to carve out a

voice, reason and permission for our clients to exist in their target audiences' lives, and we do

this by “Making Brands Matter”

Challenges We Faced

66

Challenges Faced Prior to Implementing GRC

Unreliable process for user access provisioning

• Paper based user access request forms with multiple levels of reviews, causing delays

• No ability to simulate the effect of additional access assignments and/or role updates

Excessive user access due to lack of firefighter management process

Difficulty in detecting SODs within new and existing roles

• SOD analysis was only being performed at transaction level, resulting in multiple false positives

Role creation process only took into account critical SODs which were manually referenced from an

offline matrix

SAP Access Control Implementation

Approach

88

Implementation Approach

Big Bang Approach Phased Approach

Considerations

• Full functionality of GRC provided

together

• Issues can grow quickly

• Significant learning curve in short

period of time

• Single "go-live"

• Faster access to key benefits such as

firefighter and ruleset

• Fewer issues at one time

• Allows time for lessons learned for

future phases

• Improves business acceptance of

change

• Team

• Scope and Time

• Implementation Partner

Advantages of Phased Approach

• Encourage promulgation of well thought-out specification

• Reduction of risk at multiple levels

• Complexity of planning is reduced

• Maximize control through the use of formal phase reviews

• Thorough progress reviews

• Better management of time and resources, especially of business partners

• Better change process management

• Helps overcome resistance to change

• Allows for lessons learned in early phases to be incorporated in later phases

Automated GRC Reports

1212

GRC Reports

UAR Report

• This report allows

periodic review of

access assigned to

users

• It also shows the

frequency of role

usage for each user

Action Usage by User

Report

• This report lists the

number of times a

specific transaction

was executed by a

user

Action Usage by Role

Report

• This report lists the

number of times a

specific transaction

was executed within a

role

Consolidated Log

Report

• This report contains a

log of all actions

executed during a

firefighter session

• It includes executed

transactions, changes,

system, and OS

command

1313

UAR (User Access Review) Report

The UAR reviewer will review this screen and determine whether the indicated user requires the associated

roles

Here the reviewer can

see the roles have no

usage which may

indicate that they can

be removed

1414

Action Usage by User Report

The reviewer can view the user’s executed transactions during a specific time period

Here the reviewer can

see the number of

times the action was

executed

1515

Action Usage by Role Report

The reviewer can view the number of times each transaction in a role was executed within a specific time

frame

Here the reviewer can

see that these actions

were not executed

1616

Consolidated Log Report

This report shows an activity log of all transactions executed during a firefighter session

Here the reviewer can

see additional session

details

1717

Interpretation of Action/Role Usage

Reports

1818

Role Remediation Process

We utilize the Role Level

Risk Analysis to identify

roles with inherent SOD

conflicts

Once the conflicting actions

are identified within a role, we

leverage the Action Usage by

Roles report for more insight• If the conflicting actions are

not frequently executed, the

action(s) can be removed

from the role entirely

• If the action usage is high, we

consider moving the action(s)

to a different/new role

1919

Role Level Risk Analysis

The reviewer can see which actions within the role are causing a SOD conflict

Here the reviewer can

see the actions

causing SOD risks

2020

Action Usage by Roles

The reviewer can leverage the Action Usage by Roles report to see the number of times each action was

executed in the system

Here the reviewer can

see the conflicting

actions are not being

executed and can be

removed from the role

2121

Ensuring Roles Remain Conflict Free

Going forward, the Business Role Management (BRM) module is being used for the

creation and maintenance of roles within GRC

• Prior to role generation, a risk analysis is performed to ensure the role is SOD free

• The role creation/update methodology includes a role approval step

• All role updates are logged within GRC

2222

License Audits

2323

What is a SAP License Audit

All SAP customers are contractually obligated to perform a SAP User License Audit

This process compares the number of users actively using the system and the number

of licenses the customer has purchased

GRC reports have helped Ogilvy reduce the number of unnecessary licenses and

update users to lower ranked license types

• Depending on the user’s access, the user will be categorized into different license

types which vary in cost

• Reduced 10% of licensing cost

2424

License Report

We use the USMM License Report to view the number of active licensed users currently in the system

Here is a count of the

number of users

actively using the

system

2525

Our Process to Review and Reduce the number of SAP Licenses

UAR report is run and sent to reviewer

Reviewer leverages the Action Usage reports along with the UAR report to conduct the review

Access marked for removal is removed by HR / IT Security

USMM report is run, indicating a reduction in number of SAP licenses

Any unnecessary or unused access is marked for removal

x

2626

Advantages of Using GRC Reports to Prepare for License Audits

GRC reports enable administrators to proactively remove user access prior to running

the USMM report

• GRC consolidates data in a single location, that would otherwise need to be pulled

manually and manipulated from the backend

• UAR and Action Usage reports are leveraged to easily determine the frequency of

transactions executed by individual users

• By removing excess user access, total SAP licensing costs is reduced

⬧ Some user’s license types are moved to a lower rank

⬧ SAP licenses for users not utilizing SAP are removed

Key Points to Take Home

A phased implementation approach will allow for:

⬧ Quicker adoption of key functionality

⬧ Improved business acceptance of change

GRC reports can be leveraged to help with role remediation efforts

Upon completion of role remediation process, BRM can be used on an ongoing

basis to ensure roles remain SOD free

GRC reports can be utilized outside of their conventional use

⬧ Leverage GRC to proactively remove unnecessary user access prior to

performing the license audit, which may lead to a drastic reduction in

licensing costs
