Computer networks can be characterized by their size as well as their purpose. The size of a network can be expressed by the geographic area they occupy and the number of computers that are part of the network. Networks can cover anything from a handful of devices within a single room to millions of devices spread across the entire globe. For example, telephone lines may connect communications equipment within the same building or within a home. Networks also may citywide and even international, using both cable and wireless connections. In this topic, we will discuss the different types of computer networks. 2.

    Unexpected-Behavior Detection Using Topk Rankings for Cybersecurity

    applied sciences Article Unexpected-Behavior Detection Using TopK Rankings for Cybersecurity Alvaro Parres-Peredo * , Ivan Piza-Davila and Francisco Cervantes Electronic, Systems and Informatics Department, ITESO, The Jesuit University of Guadalajara, Tlaquepaque 45604, Mexico; [email protected] (I.P.-D.); [email protected] (F.C.) * Correspondence: [email protected]; Tel.: +52-33-3669-3517 Received: 16 August 2019; Accepted: 8 October 2019; Published: 17 October 2019 Abstract: Anomaly-based intrusion detection systems use profiles to characterize expected behavior of network users. Most of these systems characterize the entire network traffic within a single profile. This work proposes a user-level anomaly-based intrusion detection methodology using only the user’s network traffic. The proposed profile is a collection of TopK rankings of reached services by the user. To detect unexpected behaviors, the real-time traffic is organized into TopK rankings and compared to the profile using similarity measures. The experiments demonstrated that the proposed methodology was capable of detecting a particular kind of malware attack in all the users tested. Keywords: cybersecurity; intrusion detection system; profiling; network security; TopK ranking 1. Introduction The Internet has been growing at a very high rate, becoming the primary global media. Due to the development of novel computing technologies and the “As Service” model, the Internet has also become the operations center of many organizations. At present, a wide variety of data is traveling on the Internet: from simple email to the entire operations data of a company. This makes computer network security more critical than ever. Day after day, information systems suffer from new kinds of attacks.
