On packet marking and Markov modeling for IP Traceback: A deep probabilistic and stochastic analysis

Abstract

From many years, the methods to defend against Denial of Service attacks have been very attractive from different point of views, although network security is a large and very complex topic. Different techniques have been proposed and so-called packet marking and IP tracing procedures have especially demonstrated a good capacity to face different malicious attacks. While host-based DoS attacks are more easily traced and managed, network-based DoS attacks are a more challenging threat. In this paper, we discuss a powerful aspect of the IP traceback method, which allows a router to mark and add information to attack packets on the basis of a fixed probability value. We propose a potential method for modeling the classic probabilistic packet marking algorithm as Markov chains, allowing a closed form to be obtained for evaluating the correct number of received marked packets in order to build a meaningful attack graph and analyze how marking routers must behave to minimize the overall overhead.

Assessment of Communication Resource Allocation by the Transmission Control Protocol for the Target Virtual Connection under Competitive Conditions

“…In their approach, reference [15] employs distinct Markovian models for different applications, which are differentiated by their well-known port numbers. Building upon this concept, reference [16] adopts and extends the modeling strategy introduced by [15] specifically for managing TCP connections.…”

“…In their approach, reference [15] employs distinct Markovian models for different applications, which are differentiated by their well-known port numbers. Building upon this concept, reference [16] adopts and extends the modeling strategy introduced by [15] specifically for managing TCP connections. The training phase remains consistent across both studies; researchers estimate separate Markovian models for different applications using corresponding training datasets.…”

“…Based on the found solutions (15), let us formulate expressions for estimating the target virtual-connection bandwidth level, which is propagated by a logical channel with characteristics L = 1, s r = 0, and controlled by the transmission protocol in the context of establishing the value of V ≥ 1 and during a sufficiently long period T (according to expression (2)):…”

Security-Reliability Trade-Off Analysis for Rateless Codes-Based Relaying Protocols Using NOMA, Cooperative Jamming and Partial Relay Selection

“…The network security is an important topic object of different studies by scientific community as shown in many papers existing in literature [1]- [3]. Conventionally, complex data encryption methods at the upper layers are used to obtain the secure communication.…”
