ANALYSIS OF MALICIOUS MENACE

Capturing the specific features of malicious threat:

Threath & attack: off-line and on-line analysis;

Modelling
strategic
interaction
of
attacker
defenders;

Theories & models: game theory and Multi agent
systems;
EXTENDED TOPOLOGICAL APPROACH

We propose an extended approach able to capture
those behaviours that can not be described by pure
topological approach.
 The main purpose is to keep the dominance of
topological approach in studying from general and
statistical perspective, but also to take into account
the physical and operation constraints that affect
considerably the assessment of power system
vulnerability.
 The traditional metrics provided by CN (Efficiency,
Betweenness, Distribution of Connectivity) need to be
revised.
