Traditional intrusion detection and logfile analysis are no longer enough to protect today's complex networks. In the updated second edition of this practical guide, security researcher Michael Collins shows InfoSec personnel the latest techniques and tools for collecting and analyzing network traffic datasets. You'll understand how your network is used, and what actions are necessary to harden and defend the systems within it. In three sections, this book examines the process of collecting and organizing data, various tools for analysis, and several different analytic scenarios and techniques. New chapters focus on active monitoring and traffic manipulation, insider threat detection, data mining, regression and machine learning, and other topics. You'll learn how to: Use sensors to collect network, service, host, and active domain data Work with the SiLK toolset, Python, and other tools and techniques for manipulating data you collect Detect unusual phenomena through exploratory data analysis (EDA), using visualization and mathematical techniques Analyze text data, traffic behavior, and communications mistakes Identify significant structures in your network with graph analysis Examine insider threat data and acquire threat intelligence Map your network and identify significant hosts within it Work with operations to develop defenses and analysis techniques

Understanding Etheridge Knight introduces readers to a major—but understudied—American poet. Etheridge Knight (1931-1991) survived a shrapnel wound suffered during military service in Korea, as well as a drug addiction that led to an eight-year prison sentence, to publish five volumes of poetry and a small cache of powerful prose. His status in the front ranks of American poets and thinkers on poetry was acknowledged in 1984, when he won the Shelley Memorial Award, which had previously gone, as an acknowledgement of "genius and need," to E.E. Cummings, Gwendolyn Brooks, and W. S. Merwin. In this first book-length study of Knight and his complete body of work, Michael Collins examines the poetry of a complex literary figure who, following imprisonment, transformed his life to establish himself as a charismatic voice in American poetry and an accomplished teacher at institutions such as the University of Hartford, Lincoln University, and his own Free Peoples Poetry Workshops. Beginning with a concise biography of Knight, Collins explores Knight's volumes of poetry including Poems from Prison, Black Voices from Prison, Born of a Woman, and The Essential Etheridge Knight. Unpdated to include a new preface, Understanding Etheridge Knight brings attention to a crucial era in African American and American poetry, and to the literature of the incarcerated, while reflecting on the life and work of an original voice in American poetry.
