Summary
We first talked about what malware is and why it's created. It's critical we grasp the nature of malware because it's the number-one issue for us right now as far as security is concerned. We also talked about DoS threats, which can be devastating. We covered the dangers of session hijacking and how attackers try to predict and overtake a user's session to use their credentials to continue their attacks, and finally, we calmed your nerves by looking at countermeasures.
In the next chapter, we'll talk about sniffing and the different types of sniffing available to us. We'll also cover how sniffing can be used in an attack and how to protect ourselves from these attacks.
