    Predicting Network Attacks Using Ontology-Driven Inference

    Full text link
    Graph knowledge models and ontologies are very powerful modeling and re asoning tools. We propose an effective approach to model network attacks and attack prediction which plays important roles in security management. The goals of this study are: First we model network attacks, their prerequisites and consequences using knowledge representation methods in order to provide description logic reasoning and inference over attack domain concepts. And secondly, we propose an ontology-based system which predicts potential attacks using inference and observing information which provided by sensory inputs. We generate our ontology and evaluate corresponding methods using CAPEC, CWE, and CVE hierarchical datasets. Results from experiments show significant capability improvements comparing to traditional hierarchical and relational models. Proposed method also reduces false alarms and improves intrusion detection effectiveness.Comment: 9 page

    New advancement in the field of e-commerce software technology has also brought many benefits, at the same time developing process always face different sort of problems from design phase to implement phase. Software faults and defects increases the issues of reliability and security, that’s reason why a solution of this problem is required to fortify these issues. The paper addresses the problem associated with lack of clear component-based web application related classification of logical vulnerabilities through identifying Attack Group Method by categorizing two different types of vulnerabilities in component-based web applications. A new classification scheme of logical group attack method is proposed and developed by using a Posteriori Empirically methodology

    Cyber criminality activities are changing and becoming more and more professional. With the growth of financial flows through the Internet and the Information System (IS), new kinds of thread arise involving complex scenarios spread within multiple IS components. The IS information modeling and Behavioral Analysis are becoming new solutions to normalize the IS information and counter these new threads. This paper presents a framework which details the principal and necessary steps for monitoring an IS. We present the architecture of the framework, i.e. an ontology of activities carried out within an IS to model security information and User Behavioral analysis. The results of the performed experiments on real data show that the modeling is effective to reduce the amount of events by 91%. The User Behavioral Analysis on uniform modeled data is also effective, detecting more than 80% of legitimate actions of attack scenarios

    With the increasing number of network threats it is essential to have a knowledge of existing and new network threats to design better intrusion detection systems. In this paper we propose a taxonomy for classifying network attacks in a consistent way, allowing security researchers to focus their efforts on creating accurate intrusion detection systems and targeted datasets

    Using Domain Knowledge to Facilitate Cyber Security Analysis

    Network attack classification is an essential component in intrusion detection in that it can improve the performance of intrusion detection system. Several machine-learning methods have been applied in correlating attacks. There is one inherent limitation with these approaches that they strongly rely on datasets, and consequently their models for attack classification can hardly generalize beyond the training data. To address the above limitation, we propose to utilize domain knowledge in form of taxonomy and ontology to improve attack correlation in cyber security. In addition, we expect that the attack correlation results of machine-learning techniques can be used to refine the original attack taxonomy. The proposed methods are evaluated with several experiments. The findings of the experiments suggest that domain knowledge and machine-learning technique should be used together on attack classification tasks

    Taxonomies for Reasoning About Cyber-physical Attacks in IoT-based Manufacturing Systems

    The Internet of Things (IoT) has transformed many aspects of modern manufacturing, from design to production to quality control. In particular, IoT and digital manufacturing technologies have substantially accelerated product development- cycles and manufacturers can now create products of a complexity and precision not heretofore possible. New threats to supply chain security have arisen from connecting machines to the Internet and introducing complex IoT-based systems controlling manufacturing processes. By attacking these IoT-based manufacturing systems and tampering with digital files, attackers can manipulate physical characteristics of parts and change the dimensions, shapes, or mechanical properties of the parts, which can result in parts that fail in the field. These defects increase manufacturing costs and allow silent problems to occur only under certain loads that can threaten safety and/or lives. To understand potential dangers and protect manufacturing system safety, this paper presents two taxonomies: one for classifying cyber-physical attacks against manufacturing processes and another for quality control measures for counteracting these attacks. We systematically identify and classify possible cyber-physical attacks and connect the attacks with variations in manufacturing processes and quality control measures. Our taxonomies also provide a scheme for linking emerging IoT-based manufacturing system vulnerabilities to possible attacks and quality control measures

    Attack Taxonomy Methodology Applied to Web Services

    With the rapid evolution of attack techniques and attacker targets, companies and researchers question the applicability and effectiveness of security taxonomies. Although the attack taxonomies allow us to propose a classification scheme, they are easily rendered useless by the generation of new attacks. Due to its distributed and open nature, web services give rise to new security challenges. The purpose of this study is to apply a methodology for categorizing and updating attacks prior to the continuous creation and evolution of new attack schemes on web services. Also, in this research, we collected thirty-three (33) types of attacks classified into five (5) categories, such as brute force, spoofing, flooding, denial-of-services, and injection attacks, in order to obtain the state of the art of vulnerabilities against web services. Finally, the attack taxonomy is applied to a web service, modeling through attack trees. The use of this methodology allows us to prevent future attacks applied to many technologies, not only web services.Con la rápida evolución de las técnicas de ataque y los objetivos de los atacantes, las empresas y los investigadores cuestionan la aplicabilidad y eficacia de las taxonomías de seguridad. Si bien las taxonomías de ataque nos permiten proponer un esquema de clasificación, son fácilmente inutilizadas por la generación de nuevos ataques. Debido a su naturaleza distribuida y abierta, los servicios web plantean nuevos desafíos de seguridad. El propósito de este estudio es aplicar una metodología para categorizar y actualizar ataques previos a la continua creación y evolución de nuevos esquemas de ataque a servicios web. Asimismo, en esta investigación recolectamos treinta y tres (33) tipos de ataques clasificados en cinco (5) categorías, tales como fuerza bruta, suplantación de identidad, inundación, denegación de servicios y ataques de inyección, con el fin de obtener el estado del arte de las vulnerabilidades contra servicios web. Finalmente, se aplica la taxonomía de ataque a un servicio web, modelado a través de árboles de ataque. El uso de esta metodología nos permite prevenir futuros ataques aplicados a muchas tecnologías, no solo a servicios web
