Overview of this book

With the increased demand for computer systems and the ever-evolving internet, network security now plays an even bigger role in securing IT infrastructures against attacks. Equipped with the knowledge of how to find vulnerabilities and infiltrate organizations through their networks, you’ll be able to think like a hacker and safeguard your organization’s network and networking devices. Network Protocols for Security Professionals will show you how. This comprehensive guide gradually increases in complexity, taking you from the basics to advanced concepts. Starting with the structure of data network protocols, devices, and breaches, you’ll become familiar with attacking tools and scripts that take advantage of these breaches. Once you’ve covered the basics, you’ll learn about attacks that target networks and network devices. Your learning journey will get more exciting as you perform eavesdropping, learn data analysis, and use behavior analysis for network forensics. As you progress, you’ll develop a thorough understanding of network protocols and how to use methods and tools you learned in the previous parts to attack and protect these protocols. By the end of this network security book, you’ll be well versed in network protocol security and security countermeasures to protect network protocols.

Questions

  1. An upper-layer packet will be encapsulated in a lower-layer packet data field for transmission (for example, TCP inside IP or IP inside Ethernet).
    1. This is always correct.
    2. This only applies in the LAN.
    3. This only applies in the WAN.
    4. This only applies when moving from the LAN to the WAN.
  2. What is the purpose of the STP?
    1. Disabling LAN switch ports for performance enhancements
    2. Creating loops in order to enable redundancy
    3. Setting port redundancy between switches
    4. Preventing loops in a LAN
  3. Which best describes the differences between TCP and UDP?
    1. TCP and UDP both have sequencing but UDP is connectionless.
    2. TCP is a reliable connection-oriented protocol, while UDP is an unreliable connectionless protocol.
    3. Both TCP and UDP are connection-oriented, but only TCP uses windowing.
    4. TCP is connection-oriented; UDP uses acknowledgments only.
  4. What layer in the OSI-RM defines end-to-end connectivity between end processes?
    1. The Physical layer
    2. The Network layer
    3. The Transport layer
    4. The Application...
