In essence, the Fourth Industrial Revolution is the trend towards automation and data exchange in manufacturing technologies and processes which include cyber-physical systems (CPS), IoT, industrial internet of things,[22] cloud computing,[23][24][25][26] cognitive computing, and artificial intelligence.[26][27]

Former drawbacks summary

it can be evaded since it is based on IP addresses, a pre-processing phase is required to make it consumable by GNN algorithms, and it does not provide relevant topological information about distributed or multi-steps attacks.

3.3 Graph-Line Representation

L(G) is the representation of G(V, E, R, X)

4.2 Phase 1 : put forward a new graph structure

graph structure:

node: flow

edge: The edges’ weights aim to enhance the GNN-based models’ pattern recognition by providing information about the two connected nodes (i.e., the two connected flows).
