Social Network Analysis – Network Theory Problem.

While reading up on outlier
cohesion analysis in collaborative social networks, I came across this article which
I found pretty interesting in the security niche; “Structural Analysis and
Destabilizing Terrorist Networks” by  N.
Memon et al. The article discusses key areas in network analysis such as

(i)                  cohesion analysis (such as cliques, ncliques, n-clans
and k-plex) to determine familiarity, robustness and reachability.
(ii)                role analysis (such as position role index) to
determine critical nodes and
(iii)               power analysis (such as degree centrality, Eigenvector centrality and dependence centrality)

This work has further
been refined and published as IEEE conference on intelligence security and ADMA

From
a generic covert network perspective, there has been previously a lot of work
done for darkNet exploration, automated discovery for nodes with case studies
in Allpeers, anoNet, Freenet, GNUnet, I2P , Tor, Turtle F2F and WASTE.

A good
overview can be found here.

The problem of network
outliers is not only crucial in intrusion detection but also an interesting
network theory problem where a leaf node posses attributes out of the ordinary.
As discussed by N. Memon et al for the social aspect of network; “The analysis
of the interaction structures that is involved in social network analysis is an
important element in the analysis of the micro-macro link, the way in which individual
behavior and social phenomena are connected with one another. In this
perspective, social networks are both the cause of and the result of individual
behavior.”
