The CCLFA Exam is a hands-on certification designed to evaluate your ability to investigate, analyze, and report on Linux systems in real-world forensic scenarios. The exam simulates an authentic case, providing you with system artifacts, logs, and disk images for analysis. The exam encompasses:
-
Linux Fundamentals: Knowledge of Linux basics, the Filesystem Hierarchy Standard (FHS), and core components.
-
Forensic Tools & Techniques: Proficiency in using essential Linux forensic tools, understanding the Linux boot process, system managers, and navigation techniques for acquiring and analyzing evidence.
-
System & Network Analysis: Skills in analyzing system services, network connections, devices, file structures, user configurations, and active processes to identify suspicious activities.
-
File System & Log Analysis: Deep understanding of the EXT4 file system, using tools like The Sleuth Kit and DebugFS, and analyzing logs to gather forensic evidence from ProcFS and TmpFS.
-
GUI & USB Forensics: Investigation of Linux GUI environments, desktop configurations, and USB activity.
-
Forensic Reporting: Report writing, with an emphasis on structure, standards, and recommendations.
Upon completion, you are required to submit a comprehensive Linux forensic report that includes:
-
Sample Handling Documentation: Methods used for obtaining, preparing, and validating the forensic data.
-
Static Analysis Findings: Identification of file system artifacts, logs, and configuration issues.
-
Dynamic Analysis Findings: Observed behavior of the system, including running processes, services, and user activity.
-
Memory Analysis Findings: Key artifacts extracted from RAM and temporary system memory.
-
Network Analysis Findings: Any anomalous network traffic, open connections, and related IOCs.
-
Technical Findings: Detailed explanation of discovered forensic evidence, system misconfigurations, or malicious activities.
-
Conclusions and Recommendations: Summarized insights, potential impact assessment, and suggestions for mitigation or further investigation.
