Projecte seguretat en xarxes i sistemes : Detecció d'intrusions amb Snort
L'objectiu principal del projecte serà implementar i conèixer a fons com funciona un IDS, i poder monitoritzar el tràfic de xarxa i/o les activitats d'un sistema per tal de detectar i evitar comportaments maliciosos, que podrien posar en perill la integritat, la confidencialitat o la disponibilitat …

A novel intrusion detection system (IDS) architecture. Attack detection based on snort for multistage attack scenarios in a multi-cores environment.
Recent research has indicated that although security systems are developing, illegal intrusion to computers is on the rise. The research conducted here illustrates that improving intrusion detection and prevention methods is fundamental for improving the overall security of systems. This research …

Network-Based Detection and Prevention System against DNS-Based Attacks
… system against the open-source detection system, Snort intrusion detection system (IDS). We evaluated the two detection systems using a confusion matrix, including the recall, false-negatives rate, accuracy, and others. The detection system detects all case scenarios of the attacks while Snort …

Research and development of a reference model for intrusion handling systems in wireless LANs
… for their evaluation. Analyses of the IHSs (Snort Wireless, Bro and Kismet) for WLANs performed in this work have shown that they are all built as proprietary systems. These IHSs do not consider the existence of other IHSs nor do they try to determine ways to establish inter-IHS collaboration …

An Architecture for Blockchain-based Collaborative Signature-based Intrusion Detection System
… and developed a prototype using Hyperledger and Snort. Our preliminary evaluation on a bench mark showed the proposed architecture offers a solution by addressing the issues of trust, data sharing and insider attacks in the network environment of CIDSs. The implications and limitations of this …

LIDS: An Extended LSTM Based Web Intrusion Detection System With Active and Distributed Learning
… detection systems has grown. Various IDSs like Snort, Zeek, Solarwinds SEM, and Sleuth9, detect malicious intent based on existing patterns of attack. While these systems are widely deployed, there are limitations with their approach, and anomaly-based IDSs that classify baseline behavior and …

Detecting exploit patterns from network packet streams
… Intrusion Detection Systems (NIDS), e.g., Snort, Bro or NSM, try to detect malicious network activity such as Denial of Service (DoS) attacks and port scans by monitoring network traffic. Research from network traffic measurement has identified various patterns that exploits on today's …

Detecting advanced botnets in enterprise networks
… encryption on three security systems, including Snort, Suricata and BotHunter (BH) using the encrypted botnet traffic generated by BotTalker. The results show that encryption foils these systems greatly. Then, we introduce a method to detect encrypted botnet traffic based on the fact that …

Multi-Vector Portable Intrusion Detection System
… mediums for malicious packet streams, the Snort-Based Wi-Fi and Bluetooth Attack Detection and Signature System (BADSS) modules were introduced. MVP-IDS illustrates that IC anomalies, representing attacks, can be correlated with wireless attack traffic through a collaborative and …

Walking Toronto's Red Road: The Story Pathways of Indigenous Social Workers
… Trickster says, slapping his knee. Cackle. Snort. Phew. After regaining some composure, he looks up off the page and back towards the reader. Tap. Tap. ‘Storytelling and land are interconnected with each other and to this anti-colonial endeavour’ Trickster says, eyebrow raised. ‘Somewhere …

An Interactive Distributed Simulation Framework With Application To Wireless Networks And Intrusion Detection
… fast lookups of network packets in the existing SNORT-based intrusion rule-set. Experiments were performed using the intrusion data from MIT Lincoln Laboratories studies, and executed on a cluster computer utilizing our distributed simulation system.

The predictive validity of the Short test of educational ability for three Virginia community colleges
… predictive validity should be determined. The Snort Test of Educational Ability (STEA) is a scholastic aptitude test score available to all Virginia Community Colleges. The STEA score is currently transmitted to the college via the student's high school transcript. Because the 1975 Virginia …

Methods for speculatively bootstrapping better intrusion detection system performance
… rates. A rudimentary prototype based on the Snort IDS, 'Probabilistic Flowbits', is described. Experimental results are then given which show substantially decreased error rates while simultaneously decreasing system overhead. In conclusion, a case is made for expanding IDS coverage and …

Developing an Advanced IPv6 Evasion Attack Detection Framework
… Intrusion Detection Systems (NIDSs) which are Snort and Suricata against some of IPv6 evasions and attack methods. The results show that both NIDSs are unable to detect most of the methods that are used to evade detection. This thesis presents a detection framework specifically developed for …

Information-fusion-based methods to improve the detection of advanced cyber threats
… alerts than a state-of-the-art rule-based IDS, Snort. We then introduce a novel technique to detect malicious lateral movement (LM). The LM attackers use the already compromised entities (e.g., hosts, accounts, and services) as stepping stones for reaching critical segments. The process of …
