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.

Vulnerability analysis tools

First, before we look at how to discover vulnerabilities, let's see what can cause them. In this category, we have the following:

  • Network devices that have not been configured according to the vendor's security procedures: Vendors provide precise and detailed procedures on how to secure the equipment, but unfortunately, not very many organizations follow them. Hackers know them, read them, and will use them to attack your network.

    Important Note

    You can search Google for hardening procedures and find them on vendor websites, such as Cisco (https://www.cisco.com/c/en/us/support/docs/ip/access-lists/13608-21.html), Juniper (https://www.juniper.net/assets/kr/kr/local/pdf/books/tw-hardening-junos-devices-checklist.pdf), and others.

  • Network devices should be updated periodically: When Cisco, Extreme Networks, HPE, Juniper, or other vendors issue upgrades or software fixes, they know why they are doing so. Don't skip them.
