    Anomaly detection using network metadata

    No full text
    Networks are traditionally configured manually by operators who can potentially introduce misconfigurations, exposing the network to security risks. Furthermore, as network complexity grows it becomes harder to track anomalous activity in networks, especially for configuration changes which may go unnoticed unless they have an immediate impact on network operation. Existing techniques for detecting anomalies rely on inspecting irregular patterns in network traffic or configuration files. In this work, we present a preliminary framework which utilizes network metadata for detecting anomalies across enterprise networks. Network metadata helps describe properties of a network that may not be expressed by traffic data, and provides an additional metric to evaluate the overall health of a network. Examples of network metadata include software version and interface status for each device in a network. We perform statistical analysis on a combination of network data plane and metadata features in order to detect anomalies as close as possible to the network’s actual behavior. Using a private enterprise dataset, we were able to analyze network metadata to identify anomalous trends which may render a network vulnerable to security threats.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2019-05-01The student, Hassan Shahid Khan, accepted the attached license on 2017-04-17 at 11:08.The student, Hassan Shahid Khan, submitted this Thesis for approval on 2017-04-17 at 11:16.This Thesis was approved for publication on 2017-04-19 at 12:51.DSpace SAF Submission Ingestion Package generated from Vireo submission #10800 on 2019-08-22 at 16:17:28Made available in DSpace on 2019-08-23T20:44:14Z (GMT).

    Hassan ibn Thabit, a True Mukhadram: A Study of the Ghassanid Odes of Hassan ibn Thabit

    No full text
    Ph.D.The seventh-century Madinan poet Hassan ibn Thabit is best known for his role as poet laureate of the Prophet Muhammad. His poetry composed in defense of Muhammad and the nascent religion of Islam has been widely studied, and it is in this context that Hassan appears in Arabic literary history. This dissertation argues that in addition to his role as an exemplar of poetry in the service of Islam, Hassan can be viewed as a true mukhadram. The mukhadramun (singular: mukhadram) were a class of poets whose lives spanned both the pre-Islamic and the Islamic periods. To appreciate Hassan's identity as a transitional figure, the poet's pre-Islamic compositions must be examined in greater depth. Prior to the rise of Islam, Hassan served as the primary court poet to the Ghassanids, a sedentary, Christian kingdom located in modern-day Syria and Jordan. This study analyzes Hassan's twenty-six Ghassanid poems and fragments. Although many of the selected poems date from the pre-Islamic period, several were composed near the end of Hassan's life when he nostalgically recalled his youth in the company of the Ghassanids. The method of analysis utilized in this dissertation relies on close reading and in-depth textual analysis of selected verses and poems.This study reveals Hassan to be a pioneer in the urbanization of Arabic poetry and a precursor to the poets of the later `Abbasid caliphate who replaced the desert themes and motifs prevalent in pre-Islamic poetry with those more appropriate to their urban environments. Hassan's compositions demonstrate not only a familiarity with the urban landscape of the Ghassanids but also a clear disdain for the pastoral lifestyle of the Arab nomads. Hassan's urbanism is one illustration of his status as a mukhadram. This study also examines the wine lyric within Hassan's Ghassanid poetry. The poet's verses in praise of wine date from both the pre-Islamic and the Islamic periods and are further evidence of Hassan's embodiment of the mukhadram predicament

    Iranian cinema in long shot

    No full text
    This thesis aims to facilitate a broader understanding of post-revolutionary Iranian filmmaking, by way of an analysis of the New Iranian Cinema and Iranian cinema in exile and diaspora, and the various relationships between these two cinemas. Thus far no significant attempt has been made to consider these two cinemas in relation to each other. This thesis therefore represents a significant contribution to this line of research. Along the way it addresses several key concepts of long-standing importance in film studies, such as notions of art cinema, authorship and national cinema, in particular how such concepts have been used as a means of studying the New Iranian Cinema. Exilic and diasporic Iranian filmmaking represents a challenge to traditional understandings of these concepts. The first chapter therefore examines how the New Iranian Cinema has been received and constructed as an archetypal 'art cinema' in Europe and North America, in addition to how this cinema invites, at the same time as it resists, such interpretations. Thereafter follows a consideration of Iranian emigre filmmaking across Europe and North America, and how it has changed over the past thirty years, gradually shifting from an exclusively exilic to a pan-diasporic outlook. Chapters three and four are individual case studies of Iranian emigre filmmakers Amir Naderi and Sohrab Shahid Saless respectively. As two of Iran's most important and influential pre-revolutionary filmmakers, the works of Naderi and Saless represent not only interesting divergences from the evolutionary understanding of Iranian emigre cinema outlined in the second chapter, but also form two of the most compelling links between the New Iranian Cinema, and it exilic and diasporic counterpart. This thesis concludes by arguing for a more flexible and open-ended conception of national cinema more generally, as well as more comprehensive, nuanced and deterritorialised understanding of post-revolutionary Iranian filmmaking

    Introduction: Up to now, the number of epidemiological studies about eating disorders (ED) in Iran is still limited. This study determined the prevalence of eating disorders in female students of Shahid Sadoughi University of Medical Sciences. Materials & Methods: A randomly selected group of 400 female students studied at Shahid Sadoughi University of Medical Sciences had been assessed. After measuring height and weight, participants were invited to complete the Eating Attitude Questionnaire (EAT-26). Results: Questionnaire was completed by 366 students (91.5%). An average prevalence of anorexia (13.11%) was found for female students. Current dieting for losing weight was reported by 20% of participants. 11.5% of participants were thin and 88% of them were not satisfied with their own weight. Frequency of eating disorders was significantly higher among overweight/obese students (p<0.001). Conclusion: Eating disorders were present in over 13 percent of female university students. Preventive programs in order to decrease the progression of these disorders should be addressed
