Overview of this book

Cybersecurity roles have grown exponentially in the IT industry and an increasing number of organizations have set up security operations centers (SOCs) to monitor and respond to security threats. The 210-255 SECOPS exam is the second of two exams required for the Cisco CCNA Cyber Ops certification. By providing you with fundamental knowledge of SOC events, this certification validates your skills in managing cybersecurity processes such as analyzing threats and malicious activities, conducting security investigations, and using incident playbooks. You'll start by understanding threat analysis and computer forensics, which will help you build the foundation for learning intrusion analysis and incident response principles. The book will then guide you through vocabulary and techniques for analyzing data from the network and previous events. In later chapters, you'll discover how to identify, analyze, correlate, and respond to incidents, including how to communicate technical and inaccessible (non-technical) examples. You'll be able to build on your knowledge as you learn through examples and practice questions, and finally test your knowledge with two mock exams that allow you to put what you’ve learned to the test. By the end of this book, you'll have the skills to confidently pass the SECOPS 210-255 exam and achieve CCNA Cyber Ops certification.

Warning Signs from Network Data

By now, you have learned about the main networking protocols in SECFND or other courses. In this chapter, we will learn how to differentiate normal header content from abnormal and rogue content to conduct an initial analysis of network intrusions.

Protocol headers contain a lot of information, so rapid identification of abnormalities is key to avoiding confusion in the workplace and in the exam. A lot of time can be lost on the exam if candidates cannot exclude normal data rapidly.

The following topics will be covered in this chapter:

  • Physical and data link layer (Ethernet) frame headers
  • Network layer (IPv4, IPv6, and ICMP) packet headers
  • Transport layer (TCP and UDP) segment and datagram headers
  • Application layer (HTTP) headers
