Magnetotelluric (MT) method is an electromagnetic technique that uses the earth natural field to map the electrical resistivity changes in subsurface structures. Because of the high penetration depth of the electromagnetic fields in this method (tens of meters to tens of kilometers), the MT data is used to investigate the shallow to deep subsurface geoelectrical structures and their dimensions....

A recent escalation of application layer Denial of Service attacks (DoS) on the Internet has quickly shifted the focus of the research community from traditional network-based denial of service. As a result, new varieties of attacks were explored: slow-rate and low-rate application layer DoS attacks. In this chapter, after a brief introduction of application layer DoS attacks, we discuss the ch...

Some of the hardest to mitigate distributed denial of service attacks (DDoS) are ones targeting the application layer. Over the time, researchers proposed many solutions to prevent denial of service attacks (DDoS) from IP and TCP layers instead of the application layer. New application Layer based DDoS attacks utilizing legitimate HTTP requests to overwhelm victim resources are more undetectabl...

meister eckhart is one of the christian mystics that christian orthodoxy and catholic church accused his thoughts in medieval ages and named him heretic. most important themes that disparate the theism of eckhart from his christian predecessors are belief to godhead beyond god, denial of possibility of knowing god, innovations about trinity, belief to apophatic theology and etc. he defended of ...

A high profile internet server is always a target of denial-of-service attacks. In this paper, we propose a novel technique for protecting an internet server from distributed denial-of-service attacks. The defense mechanism is based on a distributed algorithm that performs weight-fair throttling at the upstream routers. The throttling is weight-fair because the traffics destined for the server ...

Firewalls are critical security devices handling all traffic in and out of a network. When under heavy load of both malicious and legitimate traffic, firewalls may be overloaded and start discarding or permitting packets without checking firewall rules, which can cause huge revenue losses or security breaches. In this paper, we study Denial of Firewalling attacks, where attackers use well-craft...
