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.

    Network connections are volatile because the attacker's device is likely to be removed from the network on detection
    . Volatile data is characterized by data that can be changed or removed by factors outside of the investigator's control (for example, time or actions by other entities).
    The operating system time is volatile because it can be synchronized using NTP. If there was a discrepancy between system time and the NTP time, this discrepancy would be invisible to the investigator once it was re-synchronized.
    Paging files are not cleared when the process is ended; they simply go to unallocated. They are cleared when a new process requires that paging file and writes data to it.
    Network configuration can also be volatile. This is particularly true if DHCP is used.
    The CSIRT needs to send some of the failed hard drives to...
