Overview of this book

Effective threat investigation requires strong technical expertise, analytical skills, and a deep understanding of cyber threats and attacker techniques. It's a crucial skill for SOC analysts, enabling them to analyze different threats and identify security incident origins. This book provides insights into the most common cyber threats and various attacker techniques to help you hone your incident investigation skills. The book begins by explaining phishing and email attack types and how to detect and investigate them, along with Microsoft log types such as Security, System, PowerShell, and their events. Next, you’ll learn how to detect and investigate attackers' techniques and malicious activities within Windows environments. As you make progress, you’ll find out how to analyze the firewalls, flows, and proxy logs, as well as detect and investigate cyber threats using various security solution alerts, including EDR, IPS, and IDS. You’ll also explore popular threat intelligence platforms such as VirusTotal, AbuseIPDB, and X-Force for investigating cyber threats and successfully build your own sandbox environment for effective malware analysis. By the end of this book, you’ll have learned how to analyze popular systems and security appliance logs that exist in any environment and explore various attackers' techniques to detect and investigate them with ease.

After discussing the Windows processes, their relation, and the legitimate attributes of the most common standard Windows processes, you may now be wondering whether we can track the process creation activities using Microsoft Windows events. The answer is yes. Microsoft allows you to track every process creation and termination activity by recording two Event IDs in the security event log file:

  • Event ID 4688 records every process creation activity
  • Event ID 4689 records every process exit activity

As we will see in the next section, when investigating suspicious Windows process behavior, you will determine that those process tracking events are crucial to any incident responder, SOC analyst, and threat hunter to detect and investigate such anomalies.

Event ID 4688, named A new process has been created., is recorded in the security log file and contains very useful information about the username, process name, process path, and parent...
