The intrusion detection system (IDS) is critical in identifying abnormalities and assaults on the network, which have grown in size and pervasiveness. The paper proposes a novel method for network intrusion detection using multistage deep learning image recognition. The dataset network features are normalized and transformed into four-channel (Red, Green, Blue, and Alpha) images. The images are used to train and test the pre-trained deep learning model ResNet50. The proposed approach is evaluated using two benchmark datasets, UNSW-NB15 and BOUN Ddos. On the UNSW-NB15 dataset, the proposed method achieved 99.8% accuracy in the detection of the Generic attack. On the BOUN DDos dataset, the suggested method achieves 99.7% accuracy in the detection of the DDos attack and 99.7% accuracy in the detection of the normal traffic.
