Besides MASM exercises, the labs include several Capture the Flag exercises with development of binary vectors for buffer overflow against attacks against Linux servers, programming with "as" AT&T, in Linux, inline assembly with gnu C and C++, and programming in Java. The material in these laboratory works is based on lectures taught at Florida Tech over multiple years for the classes on Machine Architecture and Assembly Language (CSE 3120) and Computer Organization (CSE 2120). This edition is supposed to accompany lectures from Kip Irvine's book Assembly Language for x86 Processors, Editions 7 or 8. Each lab is numbered to specify the association with a chapter of that book, and references to those editions' pages and exercises are made when applicable. There are 2-3 different labs for most chapters from that book. For foundational material not found in that book, in particular for information about Linux-world assemblers like AT&T, syntax as/gas and nasm, an introduction is offered before the corresponding Labs. The book is available on lulu.com.
