Feel free to fire away at CTARGET and RTARGET with any strings you like. Figure 1 summarizes the five phases of the lab. As can be seen, the first three involve code-injection (CI) attacks on CTARGET, while the last two involve return-oriented-programming (ROP) attacks ...computer security incident is a violation or imminent threat of violation1 of computer security policies, acceptable use policies, or standard security practices.
