Today, organizations of all sizes face many
difficulties in protecting their data, systems, and tools. One
issue of particular concern is the insider threat. Insiders seek
to use their privileges to undermine data confidentiality,
validity, and availability. Any sabotage committed by
someone within a company significantly harms the
company’s integrity, credibility, and financial profits.
Automated feature extraction methods face challenges when
used to classify data due to their tendency sometimes to
return inaccurate results, leading to overfitting. Furthermore,
analyzing irregular data requires extensive manual feature
detection. We propose an algorithm that represents an expert
system that detects insiders and determines their risk level as
well. After that, the decisive step will be to intersect the
results obtained from a classification using multiple
algorithms with those obtained from the internal detection
algorithm using expert rules. This research uses several
classification methods that can deal with this type of data to
predict the status of insiders within a computer network. The
main goal of this study is to improve the accuracy and
efficiency of identifying insiders within a computer network.
Model performance evaluation includes important
parameters such as precision, recall, and F1 score. The
highest classification accuracy is obtained at 0.99, and after
combining these results with the results of the proposed
algorithm, the accuracy is 100%. These results highlight the
remarkable ability of these models to detect internal states
accurately, providing encouraging possibilities for improving
cyber security within a computer network.
