** Before you dig into some of the details related to IT security, you should have a solid understanding of core security goals. This chapter introduces many of these core goals to provide you with a big picture, and it presents basic risk concepts. Security controls reduce risks, and you’ll learn about different security control categories in this chapter. You’ll be expected to know about many Windows and Linux command-line tools, and this chapter introduces some. Last, this chapter provides details on some relevant logs and logging tools.
