Title: Critical Infrastructure Modelling

1
Critical Infrastructure Modelling
• 28th April 2003, Brno
• Ludek Novák, BDO ITludek.novak_at_bdo-it.com

Agenda
• CI Basic Terms
• Dependencies
• CI Modelling
• CI Layer Model
• CI Element Chain Model
• CI Simulation and Scenarios
• Conclusion

3
Basic Terms
• Large Complex Critical Infrastructure (CI) all
systems and assets whose incapacity or
destruction would have a debilitating impact on
the national security, and the economic and
social well being of a nation
• Large global interconnection
• Complex wide variety of services
• Critical Infrastructure Protection (CIP)measures
to secure critical infrastructure

4
Basic Terms (2)
• Critical Information Infrastructure (CII) the
totality of interconnected computers and networks
and their critical information flows
• Critical Information Infrastructure Protection
(CIIP) a subset of the CIP focuses on the
protection of ICT systems and assets.

5
Dependencies
• Intra-dependency within CI (strong dependency)
• Inter-dependency between CI (weak dependency)
• Escalating Effect disruption of one CI means
worse situation for others (delivery time)
• Cascading Effect disruption in one CI causes
disruption in a second CI
• Common Cause disruption of 2 or more CIs at the
same time e.g. natural disaster

6
CI Modelling
• Modelling involves the use of mathematical
relationships to describe a system. The user
needs to have a solid understanding of the
system specially the relationships between
events, factors and variables within the model,
and secondly the magnitude of those
relationships.

7
CI Layer Model
• The model shows parts of CI and their
relationship/dependencies
• 1, 2 or 3 dimensions
• CI sectors
• CI management fields

8
CI Sectors (1st Dimension)
• Information and Communication Services
• Electric Power Services
• Gas and Oil Services
• Banking and Finance Services
• Transportation Services
• Water and Food Services
• Emergency and Health Services
• Government Services

9
Sectors Dependencies (1)
10
Sectors Dependencies (2)
11
• Private Area home and family
• Municipal Area local government, small
organizations
• Regional Area regional government, middle
organization
• National Area state government, large
organization
• International Area cross-board cooperation,
world-wide organization

12
13
CI Management Fields(3rd Dimension)
• Social Field political and economical influence
• Organization Field management structure,
policies and regulations
• Information Field critical information exchange
• Application Field integrated functional complex
• Technological Field basic functional blocks
• Feature Field surrounding environment

14
CI Element Chain Model
• Detail description of a critical service (CIS)
• CIS Customer needs CIS
• CIS Provider offers CIS
• CIS Operator distributes CIS
• CIS Management Structure regulation
• CIS Support Structure necessary environment

15
CI Element Chain Model
16
Simulations and Scenarios
• CIs are very complex environment
• Models need solid understanding the relation
between elements, factors etc.
• We have limited knowledge on CIs
• Necessity to include implicit knowledge based on
scenarios (what-if thinking)

17
Simulations and Scenarios
18
CI Model Architecture in EU
19
Conclusion
• CI Models help us to understand the CI complexity
and CI interdependencies
• CI Models have limited applicability
• Better understanding needs a combination of
different models, simulations and scenarios
• EU have a global approach to CI Modelling
