Assessing Network Security Through Automated Attack Graph Based Multi-Level Penetration Testing, Ahmed Mohamed Hassan

Archived Theses and Dissertations

Assessing network security can be done in many different ways like applying penetration testing against target network. Penetration testing follows actual steps like reconnaissance, scanning, exploit and logical access to compromised hosts. When attacker compromises a machine, he uses it as a pivot for attacking other machines and getting access to them. An attacker continues in this process till he explores the entire target network or till he reaches his endeavor. This shows that attacks are not a single step but, to reach attackers' goal, the attacker has to go through multiple steps. Many of the available exploitation tools depend …

Measuring Atmospheric Scattering From Digital Images Of Urban Scenery Using Temporal Polarization-Based Vision, Tarek El-Gaaly

Archived Theses and Dissertations

Suspended atmospheric particles (particulate matter) are a form of air pollution that visually degrades urban scenery and is hazardous to human health and the environment. Current environmental monitoring devices are limited in their capability of measuring average particulate matter (PM) over large areas. Quantifying the visual effects of haze in digital images of urban scenery and correlating these effects to PM levels is a vital step in more practically monitoring our environment. Current image haze extraction algorithms remove all the haze from the scene and hence produce unnatural scenes for the sole purpose of enhancing vision. We present two algorithms …

An Extended Configurable Uml Activity Diagram And A Transformation Algorithm For Business Process Reference Modeling, Yosra Osama Badr

Archived Theses and Dissertations

Enterprise Resource Planning (ERP) solutions provide generic off-the-shelf reference models usually known as "best practices". The configuration !individualization of the reference model to meet specific requirements of business end users however, is a difficult task. The available modeling languages do not provide a complete configurable language that could be used to model configurable reference models. More specifically, there is no algorithm that monitors the transformation of configurable UML Activity Diagram (AD) models while preserving the syntactic correctness of the model. To fill these gaps we propose an extended UML AD modeling language which we named Configurable UML Activity Diagram (C-UML …

Software Quality Attribute Measurement And Analysis Based On Class Diagram Metrics, Dalia Rizk

Archived Theses and Dissertations

Software quality measurement lies at the heart of the quality engineering process. Quality measurement for object-oriented artifacts has become the key for ensuring high quality software. Both researchers and practitioners are interested in measuring software product quality for improvement. It has recently become more important to consider the quality of products at the early phases, especially at the design level to ensure that the coding and testing would be conducted more quickly and accurately. The research work on measuring quality at the design level progressed in a number of steps. The first step was to discover the correct set of …

Lock-Based Cache Coherence Protocol For Chip Multiprocessors, Ihab Ismail

Archived Theses and Dissertations

Chip multiprocessor (CMP) is replacing the superscalar processor due to its huge performance gains in terms of processor speed, scalability, power consumption and economical design. Since the CMP consists of multiple processor cores on a single chip usually with share cache resources, process synchronization is an important issue that needs to be dealt with. Synchronization is usually done by the operating system in case of shared memory multiprocessors (SMP). This work studies the effect of performing synchronization by the hardware through its integration with the cache coherence protocol. A novel cache coherence protocol, called Lock-based Cache Coherence Protocol (LCCP) was …

An Ontological Approach For Building A Pattern Language And A Pattern Language Management Tool, Reaham Osama Badr

Archived Theses and Dissertations

The Study of patterns and pattern inter relationships has become a recent issue tackled by many researchers. Although not many pattern languages exist yet, the importance of their existence is clearly noted. Authors argue that connecting related patterns using the relationships existing between them, gives them an additional value over individual patterns.

The main issues faced when dealing with pattern languages is how to build these languages and how to mange them afterwards. In this research work, an ontological approach is used to present a methodology for building a pattern language. This methodology is presented in the form of a …

Reputed Authenticated Routing For Ad Hoc Networks Protocol (Reputed-Aran), Abdalla Ahmed Fekry Mahmoud

Archived Theses and Dissertations

A mobile ad hoc network (MANET) is a spontaneous network that can be established with no fixed infrastructure. This means that all its nodes behave as routers and take part in its discovery and maintenance of routes to other nodes in the network. Its routing protocol has to be able to cope with the new challenges that a MANET creates such as nodes mobility, security maintenance, quality of service, limited bandwidth and limited power supply. These challenges set new demands on MANET routing protocols. With the increasing interest in MANETs, there has been a greater focus on the subject of …

Motion Detection Using Randomized Methods, Howaida Mohamed Naguib

Archived Theses and Dissertations

The detection and recogni6on of a moving object in a sequence of time varying images proves to be a very important task in machine intelligence in general and computer vision in particular. Recently, parametric domain techniques have been successfully used with a number of variants. In such melhods, the image is transfonned into some parameter space and the motion detection process is applied in that space. A recent parametric domain is the Randomized Hough Transform (RHT) that uses random sampling mechanism in the image space, score accumulation in the parameter space, and bridge between them using a converging mapping. The …

A Step Towards A Well Engineered Component Based Extensible Operating System, Mohamed Fathey Abdel Fattah

Archived Theses and Dissertations

Operating systems are the first developed piece of software for a computer and it is still the first application to run over our computers. Software developers spent a lot of time and efforts to build reliable systems using different philosophies and software engineering strategies. They built monolithic kernels, micro-kernels, pico-kernels, etc. to fulfill users' requirements and hardware developments as well. However, Most of the proposed solutions for operating systems design and implementation are for solving traditional problems. Operating systems are still constructed as a general piece of software used for either machine's resource management or as a virtual machine for …
