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.

    HTTP is
    not a secure method of bulk data transfer. Data transferred over HTTP is sent in plaintext. HTTPS is a better and more secure protocol, and there are also more efficient methods of bulk data transfer (for example, FTP).
    DNS and HTTP are fundamental to many network applications and therefore are likely to be enabled on corporate networks. This gives data relating to an incident a greater likelihood of successfully entering or leaving the network. This data will also be masked by the large volume of legitimate traffic.
    DNS allows attackers to create code that doesn't directly reference the destination IP address. They can use a domain name or URL, which can then be registered closer to the time of deployment.
