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.

Chapter 2: Operating System Families

  1. (1)
    HeapAlloc is used for dynamic allocation. When the application requests memory, the right amount of memory is allocated. (VirtualAlloc is described in question 2.) Swap is a Linux virtual memory system and is described in question 3. CoTaskMemAlloc is used when memory must be shared.
  2. (2)
    VirtualAlloc utilizes reserved blocks of memory. This means that it is suitable for specialized usage where the memory required is known at the time of creating the process. HeapAlloc was described in question 1. LocalAlloc is a specialized version of HeapAlloc, which allows memory to be moved via reallocation. Pages are the files that store virtual memory.
  3. (1) and (2)
    Linux can utilize a swap partition or swap files to provide extra memory on the hard disk drive or SSD to expand the system's physical memory. Swap file/swap partition capacity must...
