According
to numerous increasing of worm malware in the networks nowadays, it became a serious danger that threatens our computers. Networks
attackers did these attacks by designing the worms. A designed system model is
needed to defy these threats, prevent it from multiplying and spreading through
the network, and harm our computers. In this paper, we designed a detection
system model for this issue. The designed system detects the worm malware that
depends on the information of the dataset that is taken from Kaspersky company
website, the system will receive the input package and then analyze it, the Naïve
Bayesian classification technique will start to work and begin to classify the
package, by using the data mining Naïve Bayesian classification technique, the
system worked fast and gained great results in detecting the worm. By applying
the Naïve Bayesian classification technique using its probability mathematical
equations for both threat data and benign data, the technique will detect the
malware and classify data whether it was threat or benign. The results of the
experiments were 95% of worm detection accuracy and 98% of detection rate with
21% false positives, which makes it more accurate and effective to detect the
worm malware by using the proposed dataset for this work.
