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 broad consequences
  • 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 administration areas
  • 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)

Sectors Dependencies (2)
11
CI Administration Areas (2nd Dimension)
  • 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
Sector vers. Administration
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
