Detection of denial-of-service attacks based on computer vision techniques
A Denial-of-Service (DoS) attack is an intrusive attempt, which aims to force a designated resource (e.g., network bandwidth, processor time or memory) to be unavailable to its intended users. This attack is launched either by deliberately exploiting system vulnerabilities of a victim (e.g., a …

Denial-of-service attack modelling and detection for HTTP/2 services
… caused by the adversary class. A malicious attack that can prevent establishment of Internet connections to web servers, initiated from legitimate client machines, is termed as a Denial of Service (DoS) attack; volume and intensity of which is rapidly growing thanks to the readily available …

Denial-of-Service Attacks on Battery-Powered Mobile Computers
A Denial of Service (DoS) attack is an incident in which the user is deprived of the services of a resource he is expected to have. With the increasing reliance on mobile devices like laptops and palmtops, a new type of DoS attack is possible that attacks the batteries of these devices, called …

On modeling and mitigating new breed of dos attacks
Denial of Service (DoS) attacks pose serious threats to the Internet, exerting in tremendous impact on our daily lives that are heavily dependent on the good health of the Internet. This dissertation aims to achieve two objectives:1) to model new possibilities of the low rate DoS attacks; 2) to …

Detection of Denial of Service Attacks on the Open Radio Access Network Intelligent Controller through the E2 Interface
… volumetric application layer Denial of Service (DoS) attacks exploiting the E2 interface and the E2 Application Protocol (E2AP). We design a DoS attack agent capable of orchestrating a signaling storm attack and a high-intensity resource exhaustion DoS attack on the Near-RT RIC platform …

Security in home IoT environments
… papers on the topic and to run several malicious attacks based on the read material on an IoT environment. After running the different attack tests on the environment, the next step is remediating the security issues. The IoT environment is a home experiment environment, which is set up by using …

Security threats to the MAC-layer in wireless networks
… often ignore two other threats to security: attacks against availability and incorrect implementation of MAC protocol and driver routines. The former can prevent a user from communicating at all, whereas the latter can have consequences ranging from dropped packets to complete host …

A security evaluation of the salsa anonymous communication system
… the techniques that are used to combat active attacks on the lookup mechanism dramatically increase information leaks and increase the efficacy of passive attacks. Thus there is a tradeoff between active and passive attacks. We find that, by combining both passive and active attacks, anonymity …

Enhancing ISP-consumer security notifications
… of Things devices engage in denial of service (DoS) attacks and ransomware holds data on personal and commercial systems hostage. Many of these threats are relatively opaque for an end user. An end user may not know that their smart device is participating in a DoS attack at all, unless they …

Statistical anomaly denial of service and reconnaissance intrusion detection
… System (RIDS); the former is denial-of-service (DoS) attack detector while the latter is a scan and probe (P&S) reconnaissance detector; both are statistical anomaly systems. The HIDE is a packet-oriented, observation-window using, hierarchical, multi-tier, anomaly based network intrusion …

A model to study cyber attack mechanics and denial-of-service exploits over the internet's router infrastructure using colored petri nets
… is vulnerable to targeted denial-of-service (DoS) attacks. Protecting this infrastructure‟s stability is a vital national interest because of the dependence of economic and national security transactions on the Internet. Current defensive countermeasures that rely on monitoring specific router …

Evaluation of Moving Target IPv6 Defense and Distributed Denial of Service Defenses
A Denial-of-Service (DoS) attack is a network attack from a single machine that attempts to prevent the victim, the targeted machine, from communicating to other devices on the network or perform its normal tasks. The extension of these attacks to include many malicious machines became known as …

Machine learning-based intrusion detection system in advanced metering infrastructure
… is vulnerable to serious threats. To detect attacks, many authors recommend using Intrusion Detection Systems (IDSs). An IDS use a classifier to distinguish between known and unknown threats. It is challenging to choose the proper IDS category, however, as no single category can accurately …
