Penetrační testování ANC / Penetration testing of ANCDušek, Jakub January 2021 (has links)
This diploma thesis deals with the evaluation of a security solution that was recently deployed by a British company renting office space. This validation system is based on a database of MAC addresses, a database of clients and active filtering of connected devices. The first part explains the concepts of computer network, VLAN and basic concepts needed to understand the function of dynamic assignment of VLAN and IP addresses. The second part is devoted to measurements based on hypotheses, according to which measures are proposed in the last part to solve these security problems.

Odolnost komunikační jednotky LAN proti útokům z Internetu / LAN communication unit resistivity against Internet origination attacksValach, Michal January 2009 (has links)
This thesis is focused on crypto-module RCM 3700, which is used for encrypted data transmission. Following work analyses basic network protocols and some sort of attacks in Ethernet network. The main goal of these attacks is to collect information and services about the device and to analyze transmitted data. Based on these information attacks can be done more precisely than without them. The main target of these attacks is the denial of particulary service or data abuse. Furthermore, in the diploma thesis configuration of router CISCO 2801 is applied in order to improve the LAN security. The deveploment board, which includes reset function, supplied circuit and interface for RS 232, was designed for crypto-module RCM 3700.

Implementations of Fourier Methods in CFD to Analyze Distortion Transfer and Generation Through a Transonic FanPeterson, Marshall Warren 01 June 2016 (has links)
Inlet flow distortion is a non-uniform total pressure, total temperature, or swirl (flow angularity) condition at an aircraft engine inlet. Inlet distortion is a critical consideration in modern fan and compressor design. This is especially true as the industry continues to increase the efficiency and operating range of air breathing gas turbine engines. The focus of this paper is to evaluate the Computational Fluid Dynamics (CFD) Harmonic Balance (HB) solver in STAR-CCM+ as a reduced order method for capturing inlet distortion as well as the associated distortion transfer and generation. New methods for quantitatively describing and analyzing distortion transfer and generation are investigated. The geometry used is the rotor 4 fan geometry, consisting of one rotor and one stator. The inlet boundary condition is a 90-degree sector total pressure distortion profile with total pressure and swirl held constant. Multiple HB simulations with varying mode combinations and distortion intensities are analyzed and compared against full annulus Unsteady Reynolds Averaged Navier-Stokes (URANS) simulations. Best practices and recommendations for the implementation of the HB solver are given. The pre-existing Society of Automotive Engineers Aerospace Recommended Practice (SAE-ARP) 1420b descriptors are demonstrated to be inadequate for the purposes of analyzing distortion transfer and generation on a stage-to-stage basis. New implementations of Fourier methods are presented as an alternative to the SAE-ARP 1420b descriptors. These Fourier descriptors are shown to describe distortion transfer and generation to a higher degree of fidelity than the SAE-ARP 1420b descriptors. These new descriptors are demonstrated on the analysis of full annulus URANS and HB simulations. The HB solver is shown to be capable of capturing distortion transfer, generation and performance degradation. Recommendations for the optimal implementation of the HB method are given.

Granskning och optimering av data- och IP-telefoninätverkEriksson, Jhonny, Karlsson, Joel January 2010 (has links)
<p>The company Västra Mälardalens Kommunalförbund, VMKF, wishes to revise and optimize their present data and IP-telephony network as of today consists of the three municipalities Köping, Arboga and Kungsör. As a municipal corporation, they seek consultation regarding internal as well as external review and investigation of the main structure of the network, its functionality and safety. By today’s increasing demands of Internet accessibility, availability of services and security far more extends the requirement of a complete network design. The foundation of networking rests on the balance between each of these necessities. Therefore, it is of grave importance to optimize a network design, use of hardware and to minimize the administrative overhead. In particular, when the municipality is short of resources and time means money. By letting an impartial investigation of the network act as a starting point it was established that several improvement could be applied. Among these a reconstructed and improved network topology that includes subjects as routing, switching, safety and security, quality of service and technical administrative overhead and the implementation of a real time monitoring of network bandwidth consumption.</p> / <p>Företaget Västra Mälardalens Kommunalförbund, VMKF, har önskemål om att granska och optimera deras befintliga data- och IP-telefoninätverk som i dagsläget spänner över de tre kommunerna Köping, Arboga och Kungsör.

Genom att låta en granskning över nätverket som det ser ut i dag ligga till grund konstaterades att flertalet förbättringsmöjligheter kunde genomföras.

Entwicklung des Kommunikationsteilsystems für ein objektorientiertes, verteiltes BetriebssystemBecher, Mike 09 November 1998 (has links)
Thema dieser Arbeit ist die Entwicklung eines Kommunikationsteilsystems fuer
das Experimentiersystem CHEOPS zur Ermoeglichung einer Interobjektkommunika-
tion zwischen Objekten auf dem gleichen bzw. verschiedenen Systemen.
Ausgangspunkte stellen dabei eine verfuegbare Implementation eines Ethernet-
Treibers der Kartenfamilie WD80x3 fuer MS-DOS, eine geforderte Kommunikations-
moeglichkeit mit UNIX-Prozessen sowie die dort benutzbaren Protokoll-Familien
dar.
Die Arbeit beschaeftigt sich mit der Analyse und Konzipierung des Ethernet-
Treibers sowie der Internet-Protokoll-Familie fuer CHEOPS als auch deren
Implementation resultierend in einem minimalen Grundsystem. Weiterhin wird
ein erster Entwurf fuer ein spaeter weiterzuentwickelndes bzw. zu vervoll-
staendigendes Netz-Interface vorgeschlagen und durch eine Beispiel-Implemen-
tierung belegt.
