Traditionally,
intrusion detection systems have proven unreliable when detecting stealthy or
low-rate types of attacks. Increasing numbers of cyber threats have accelerated
the need for better ways to monitor network activity. In this paper, we discuss
the advantages of analyzing NetFlow data in order to detect intrusion anomalies
without packet-level analysis. The methodology we propose is based on deep
learning and NetFlow data sets, applied to detect anomalies in a given network
environment. We will perform preprocessing on the flow data set and extract the
relevant attributes using Autoencoder and LSTM networks. Finally, our findings
reveal that this methodology exceeds performance through its enhanced ability
to detect subtle attacks. The framework offers a scalable and efficient
solution for improving real-time network security.
