本教材以黑客入侵實踐為主線, 體系結構圍繞黑客入侵的各個環節展開, 即網絡掃描、抓包分析、腳本書寫、服務與網站漏洞利等, 最後兩章分別介紹了系統加固的方法以及歷年網絡安全大賽部分的賽題。本教材編寫的目的是提高學生對網絡空間安全中理論知識的理解, 掌握基本的網絡滲透工具的使用, 領會網絡攻擊中常用的方法和手段。本教材的學習需要計算機網絡基礎、服務器配置、python語言等課程作為前導課程, 本教材的學習也為學生今後深入學習網絡攻防知識以及成為一名合格的網絡滲透、網絡運維工程師做準備。

Maths + history + jokes - boring bits = A Quick History of Maths. This book begins around 43,000 years ago with a notched baboon leg, the Lebombo bone (the very first mathematical object in the world) and rushes us past Hindu numerals and the invention of zero, via Pythagoras, Pascal and probability, right up to the present day, with big data and the maths that rules our digital lives. Geometri-coolYou will discover:How to count on your fingers (there are more ways than you might think )Why we have 60 seconds in a minute (hint: it's to do with the ancient Babylonians)How to count like an Egyptian (using hieroglyphs)Why it's hip to be square using square numbersA Pythagorean party trickThe naked truth of Archimedes' bath time mathematicsHow to do matha-magic with magic squares...and much more.In chronological order from pre-history to present day, this is the story of maths itself. It's 43,000 years of human mathematical endeavor squeezed into one book for your reading pleasure. Illustr
