Chapter 7: Attacks on Systems and Networks
So far the threats have mostly arrived through people and files. This chapter looks at the systems and networks themselves — how an attacker studies a target, slips in, gains power, and finally acts. You will see that a real attack is rarely one dramatic moment, and that each step it takes is a separate chance to stop it.
News stories make a breach sound like a single instant — a screen flashes, and suddenly someone is "in." Real attacks almost never work that way. They unfold as a sequence of small, ordinary-looking steps, often spread over days or weeks. This chapter takes that sequence apart so the next breach story you read becomes a thing you can actually follow.
We start with the path an attacker tends to walk: look around, get in, gain more power, then act. Then we look at three concrete attacks that hang off that path — quietly listening in on a network, knocking a system offline, and tricking software through the very data it accepts. Olivia's everyday situations show what each one looks like from the outside; the goal is understanding, not a to-do list.
