CompTIA Security+™: Study Guide, Fourth Edition

This chapter focused on the types of attacks you'll encounter and your network's vulnerabilities:

• Types of attack

• TCP/IP

• Malicious code

• Social engineering

Denial of service, distributed denial of service, back door attacks, spoofing attacks, man-in-the-middle attacks, and replay attacks are all types of attacks you may encounter. Each takes advantage of inherent weaknesses in the network technologies most commonly used today.
