Introduction

The process of digital evidence collection in cybersecurity investigations hinges critically on understanding the volatility of different data types. Recognizing what data is volatile or non-volatile, and collecting such evidence in the correct order, ensures that pertinent information is preserved before it can be lost, thus maintaining the integrity of the investigation. This paper explores the volatility status of SSDs, virtual memory, CPU cache, and printouts, emphasizing the importance of following the order of volatility, and outlines methods for collecting and analyzing at least two types of evidence from these categories.

Identification of Volatile and Non-Volatile Data and Their Correct Order of Volatility

The assessment of the evidence types requires understanding their volatility characteristics. Virtual memory and CPU cache are considered volatile data. Virtual memory, which includes RAM, temporarily stores active data and execution information and is lost when the system is powered down. CPU cache, containing high-speed data meant for quick processing, also vanishes once the system is shut off. SSDs and printouts are non-volatile; SSDs permanently store data even when power is lost, and printouts, as physical representations, retain data indefinitely, unless physically destroyed.

The correct order of volatility traditionally prioritizes collecting data that is most likely to be lost first. Therefore, the order would be:

1. CPU Cache

2. Virtual Memory

3. SSD

4. Printouts

This sequence ensures that the most transient data is captured first, maintaining the completeness of the evidence for forensic analysis.

Importance of the Order of Volatility

Following the correct order of volatility is essential in digital forensics to prevent the loss of critical volatile evidence. If volatile data like CPU cache and virtual memory are not promptly collected, they may be overwritten, evaporate with power loss, or get lost due to system resets. This can severely impair the ability to reconstruct events or identify malicious activities accurately. Collecting data in the proper sequence preserves the temporal integrity, guaranteeing all potentially valuable information is available for analysis, which is crucial in legal contexts and incident response.

Methods to Collect and Analyze Evidence

1. Collecting and Analyzing Virtual Memory

Virtual memory can be collected by capturing the system’s RAM image using specialized tools such as FTK Imager or WinDd. These tools create bit-for-bit copies of the current RAM contents while the system is live. Once captured, the analysis involves examining the memory dump for running processes, encryption keys, malware, or other transient data relevant to the investigation. Tools like Volatility enable investigators to parse through memory images to identify active processes, network connections, and hidden artifacts that provide insights into the incident.

2. Collecting and Analyzing CPU Cache Data

Collecting CPU cache data is more complex, often involving hardware-based techniques and specialized forensic tools that can extract cache contents without system shutdowns. Techniques include using direct memory access (DMA) or side-channel analysis tools to access cache data. Analysis focuses on identifying residual data that may include encryption keys, login credentials, or other sensitive information. Employing forensic tools such as CacheViewer assists investigators in examining cache residues to reconstruct recent activity, which can be pivotal in identifying malware or unauthorized access.

3. Collecting SSD Data

Since SSDs are non-volatile, they can be physically or logically imaged using forensic tools such as EnCase or FTK Imager. The process involves creating a bit-by-bit duplicate of the SSD, which can then be analyzed independently of the original device to prevent data alteration. The analysis focuses on file system artifacts, deleted files, or residual data that may hold evidential value. Forensic examination of the SSD can reveal stored user or system data, artifacts of malicious activity, or deleted evidence.

4. Analyzing Printouts

Printouts, being physical evidence, are analyzed through careful visual inspection and digital transcription if necessary. They can be examined for markings, annotations, or embedded data that might offer insights into the incident. Digitizing printouts into scanned images allows for further digital analysis, such as keyword searches or pattern recognition. They serve as tangible records that can corroborate digital evidence.

Conclusion

Understanding the volatility of various digital evidence types and adhering to the correct order of collection are fundamental in preserving the integrity of digital investigations. Volatile memory components like CPU cache and virtual memory must be prioritized to capture transient data before it is lost. Proper collection and analysis techniques, tailored to each evidence type, enable forensic professionals to reconstruct events accurately and support legal proceedings effectively. As digital environments become more complex, the discipline of evidence collection continues to evolve, emphasizing the importance of systematic and methodical procedures rooted in an understanding of data volatility.
