There is provided a method for adapting components of a network, comprising: providing graphs each indicative of a respective sequential snapshot of a dynamic graph obtained over a historical time interval, wherein nodes of the graphs denote entities, and edges of the graphs denote interactions between the entities over a network, computing community graphs according to the graphs, computing meta-community graphs according to the community graphs, analyzing dynamics of the community graphs to detect changes between two temporally adjacent community graphs, analyzing dynamics of the meta-community graphs to detect changes between two temporally adjacent meta-community graphs, identifying at least one entity corresponding to node(s) of the dynamic graph according to a predicted likelihood of performing an anomalous action during a future time interval, and generating instructions for adapting component(s) of the network for ensuring availability of network resources for interactions between entities during the future time interval.
