Denial of Service(DoS) attacks pose a big threat to any electronic society. DoS and DDoS attacks are catastrophic particularly when applied to highly sensitive targets like Critical Information Infrastructure. While research literature has focussed on using various fundamental classifier models for detecting attacks, the common trend observed in literature is to classify DoS attacks into the br...

DoS attacks (Denial of Service) are one of the main problems on computer security field. Usually these attacks result in the loss of network connectivity due to excessive bandwidth-consuming and resource bottlenecks of the system attacked. DoS attacks can occur in various ways; however all of them have in common the use of IP protocol. This work presents the effects on network elements and secu...

Eletrodo de diamante foi usado para avaliar a interação dos nucleotídeos guanosina monofosfato (GMP) e adenosina monofosfato (AMP) com os pesticidas clorpirifós, metamidofós e monocrotofós. Observaram-se alterações nas correntes e potenciais de picos dos voltamogramas dos nucleotídeos na presença dos pesticidas dependendo da concentração de pesticida (de 5,0 × 10 a 5,0 × 10 mol L) e do tempo de...

Article history: Received 15 February 2015 Received in revised form 2 December 2015 Accepted 3 December 2015 Available online 23 March 2016 The modeling of the transient subgap density of states (DOS) for the investigation of trap densities in the oxidebased thin-film transistors is proposed. The study is based on both transient measurements and physical modeling. In history, the subgap DOS mod...

Malicious intruders may launch as many invalid requests as possible without establishing a server connection to bring server service to a standstill. This is called a denial-of-service (DoS) or distributed DoS (DDoS) attack. Until now, there has been no complete solution to resisting a DoS/DDoS attack. Therefore, it is an important network security issue to reduce the impact of a DoS/DDoS attac...

Diffuse optical spectroscopy (DOS) of breast tissue provides quantitative, functional information based on optical absorption and scattering properties that cannot be obtained with other radiographic methods. DOS-measured absorption spectra are used to determine the tissue concentrations of deoxyhemoglobin (Hb-R), oxyhemoglobin (Hb-O2), lipid, and water (H2O), as well as to provide an index of ...

In recent years, Wireless Voice over IP (WVoIP) has been one of the most popular telecommunication technologies. Quality of Service (QoS) and security are two important issues which determine the success of WVoIP. WVoIP QoS issues have been extensively studied. However, security issues of WVoIP are rarely addressed. In this paper, we study one important WVoIP security issue of Denial of Service...

Denial of Service (DoS) attacks can be easily launched in Wireless Sensor Networks (WSNs). Due to their resource constraints, namely limited energy, memory and bandwidth, WSNs are especially vulnerable to DoS attacks. This paper addresses a particular class of DoS attacks that overwhelm resources along a multihop data delivery path. Since WSNs are typically tree-structured, then a DoS attack on...

This paper addresses the security issue of networked control systems (NCSs) under DoS attacks. According to the level of attacks, DoS attacks are classified into two types: weak attacks and strong attacks. A recursive networked predictive control (RNPC) method based on round-trip time delay is proposed to compensate for the adverse effects introduced by the weak DoS attacks as well as the netwo...
