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.

Attacks on the management plane and how to defend against them

The management plane is the part of the device responsible for controlling the device—that is, to log in to the device and configure it, to receive SNMP commands, to send SNMP traps and System Logging Protocol (Syslog) messages to a management console, and so on.

For this reason, attacks on the management plane can be categorized as follows.

The first sorts of attacks are brute-force attacks for password discovery, such as the following:

  • Brute-force attacks for password discovery—Telnet, Secure Shell (SSH)
  • Brute-force attacks against SNMP passwords (community strings)
  • Brute-force attacks against HyperText Transfer Protocol (HTTP)/HTTP Secure (HTTPS) passwords
  • Brute-force attacks on proprietary-access applications

The next kinds of attacks are attacks on the management plane intended to interfere with the management of the device. In this category, we have the following:
