EnterCard delivers smart payment and financing solutions to

customers. We have over 50 card products and 2 million

customers across Scandinavia

• There are requirements and use cases for EA modeling in many

areas – solution design, work instructions, IT planning,

knowledge management, training, master data, project

management, business transformation, incident management,

risk management and more.

• There is currently no single modeling standard that covers all of

this.

• So, we have combined severel EA standards into a larger

framework, with modeling conventions independent of any

particular tool. (We use ARIS.)

• Our main effort so far has been as-is documentation in relation

to Business Continuity Management and impact analysis, but

we are also proceeding in other areas.

This presentation is about how the EA framework we have

developed so far could cover risk modeling going forward. Note

that this presentation does not cover how EnterCard is actually

working with risk management today.

First, some considerations regarding risk mangement vs. EA...

Introduction

• “For too long, information security has been considered a

separate discipline, isolated from the enterprise architecture”

• “Operational risk and its relevance to enterprise architecture

– why incorporating the concept of operational risk is

essential to modern enterprise architecture design. “

• “This White Paper is intended to guide enterprise and

security architects in fully integrating security and risk

management into enterprise-level architectures “

SABSA and TOGAF - “Integrating security and risk

management into enterprise-level architectures”

EA 5

The SABSA Operational Risk Model

“The IT security and information security industry has evolved over its lifetime a

view of operational risk that is concerned only with threats, vulnerabilities, and

loss events (negative impacts)--- This negative approach to risk management

has also found its way into the ISO/IEC 27005:2011 standard…“

“Arguably, the sole role of the enterprise architect is to create an operational

environment in which operational risk can be optimized for maximum business

benefit and minimum business loss.”

• “In SABSA thinking these operational capabilities are the

primary assets at risk… examples… Production capability,

Service delivery capability... Capability to build and sustain

brands and reputation…”

• «In traditional information and IT risk management

frameworks … the assets at risk are usually classified as

information assets (databases, files, documents, etc.) and IT

assets (computer hardware, software, communications

networks, etc.). These are regarded in SABSA as secondary

assets, supporting the primary assets of business capability

• “SABSA risk assessment, risk measurement, and risk

monitoring focuses on the primary assets…”

• “In this respect SABSA is leading-edge thinking, challenging

the traditional IT view of operational risk management, but

aligning operational risk with true business risk.”

Risk & Impact viewpoint (custom)

18

Asset at risk: Any object,

including capability

Planned enhancements:

• Threat agent

• Opportunity

Assets at risk

19

SABSA view: The output of architecture work

is the creation of operational capability.

These operational capabilities are the

primary assets at risk.

Example: Capability to build and sustain

brand and reputation

SABSA based view of primary

vs. secondary assets:

«Indirect impacts»:

Example: An incident related to e.g. an IT

system «indirectly» impacts «Reputation» Either way, we can model it

Example impact viewpoint

Keep it simple – risk attribute for BPMN tasks

© EnterCard, 18 December, 2012

BPMN process modelers can choose to specify

a Risk attribute, in which case an «attribute

symbol» is automatically inserted.

More advanced modelers can create

connected Archimate models (with

extensions)

Change management is key

Anticipated extensions to the modeling framework

• Building on the Archimate metamodel enables us to

consistenly model the entire enterprise architecture with full

traceability between risks and assets.

• This modeling framework supports traditional risk modeling

with a focus on threats and negative impacts as well as e.g.

the SABSA approach which also deals with opportunites and

positive impacts.

• Consequently, architecture and risk go hand in hand and

marries business improvement
