This study introduces a novel graph self-supervised learning approach for network intrusion detection, enhancing graph representation to improve detection accuracy with less labeled data.

Area of Science:

  • Cybersecurity
  • Machine Learning
  • Network Security

Background:

  • Existing intrusion detection systems (IDS) often require extensive labeled data.
  • Challenges include capturing complex network topologies and utilizing edge information.
  • Limitations in current IDS hinder effective detection of sophisticated network attacks.

Purpose of the Study:

  • To propose a semantic-guided edge enhancement approach for graph self-supervised learning in network intrusion detection.
  • To address the limitations of existing IDS, particularly the reliance on labeled data and the inability to capture complex network structures.
  • To enhance the discriminability of network flow graphs for improved intrusion detection.

Main Methods:

  • Introduced a node-edge-node attention algorithm for graph enhancement representation.
