Defend the network layer from malicious attack

The network layer is key to the operation of the stack. In this sample chapter from Hack the Stack: Using Snort and Ethereal to Master the 8 Layers of an Insecure Network, begin by reviewing the protocols that reside here, such as Internet Protocol (IP), Internet Control Message Protocol (ICMP), and routing protocols. Next, take an in-depth look at the types of attacks you need to be aware of at this layer. Finally, explore the types of controls that can be implemented to secure the network layer. Chapter coverage includes:

• Understanding the IP packet structure
• Understanding the ICMP packet structure
• Attacking the network layer
• Defending the network layer
• Introducing the Network Layer Security Project
