Forensic data acquisition by volatility priority

Should evidence be collected in the order of volatility?
Collecting evidence
It's a good idea to prioritize the evidence to be collected.
Generally, we want to start with the most volatile evidence first.
In computer parlance, this is known as the order of volatility.
This descending list works from the most volatile (RAM) to the least volatile (archived data)..
What is the forensic order of volatility?
Order of volatility refers to the order in which you should collect evidence.
Volatile doesn't mean it's explosive, but rather that it is not permanent.
In general, you should collect evidence starting with the most volatile and moving to the least volatile._{Jun 27, 2021}.
What is the forensic relevance of volatile data?
Volatile Data use cases:
In digital forensics, investigators capture and analyze volatile data.
They gather evidence, identify active processes, and uncover recent user activity.
Cybersecurity.
Analysts can examine volatile memory to identify running processes, malicious code, and unauthorized activities..
What is the most volatile data forensics?
The order of volatility is:
CPU, cache, and register content.Routing table, ARP cache, process table, kernel statistics.Memory.Temporary file system/swap space.Data on hard disk.Remotely logged data..
What is the order of volatility and why is it important in forensics?

What is the order of volatility in forensic investigation?
The order of volatility is the sequence or order in which the digital evidence is collected.
The order is maintained from highly volatile to less volatile data.
Highly volatile data resides in the memory, cache, or CPU registers, and it will be lost as soon as the power to the computer is turned off._{Nov 23, 2017}.
What is the recommended order of volatility in evidence collection?
In general, you should collect evidence starting with the most volatile and moving to the least volatile.
For example, random access memory (RAM) is lost after powering down a computer._{Jun 27, 2021}.
What is the significance of order of volatility in evidence collection?
When collecting evidence, we should keep in mind the volatility of data.
As mentioned earlier in this chapter, data can be easily lost or destroyed.
As such, when collecting data, a well-documented and common best practice would be to collect evidence in the order of most volatile to the least volatile if possible..
Data that is very volatile is data that's in your CPU.
So things like your CPU registers or CPU cache should be the very first thing you gather.
Secondly, would be information that would be around for a little bit longer than CPU information, but not much longer.
The four methods of acquiring data for forensics analysis are disk- to- image file, disk-to- disk copy, logical disk- to- disk or disk- to- data file, or sparse data copy of a folder or file.
Large disks might require using tape backup devices.
With enough tapes, any size drive or RAID drive can be backed up.

Less volatile data cannot be lost easily and is relatively permanent because it may be stored on disk drives or other permanent storage media, such as floppy discs and CD-ROM discs. The crime scene technicians should collect evidence beginning with the most volatile and then moving towards a least volatile.

One of the many procedures that a computer forensics examiner must follow during evidence collection is order of volatility. During the process of collecting digital evidence, an examiner is going to go and capture the data that is most likely to disappear first, which is also known as the most volatile data.

The IETF and the Order of Volatility This document explains that the collection of evidence should start with the most volatile item and end with the least volatile item. So, according to the IETF, the Order of Volatility is as follows: Registers, Cache. Routing Table, ARP Cache, Process Table, Kernel Statistics,

Disk

Even though we think that the data we place on a disk will be around forever, that is not always the case (see the SSD Forensic Analysis post from June 21).
However, the likelihood that data on a disk cannot be extracted is very low.

How do I acquire volatile digital evidence?

There are several other options that have become available that the author has become familiar with to acquire volatile digital evidence - live data including:

creating an image of RAM in a forensically sound manner (in no specific order):
In digital evidence collection today live forensics has become a necessity

Registers, Cache

The contents of CPU cache and registers are extremely volatile, since they are changing all of the time.
Literally, nanoseconds make the difference here.
An examiner needs to get to the cache and register immediately and extract that evidence before it is lost.

Remote Logging and Monitoring Data That Is Relevant to The System in Question

The potential for remote logging and monitoring data to change is much higher than data on a hard drive, but the information is not as vital.
So, even though the volatility of the data is higher here, we still want that hard drive data first.

Routing Table, Arp Cache, Process Table, Kernel statistics, Memory

Some of these items, like the routing table and the process table, have data located on network devices.
In other words, that data can change quickly while the system is in operation, so evidence must be gathered quickly.
Also, kernel statistics are moving back and forth between cache and main memory, which make them highly volatile.
Finally, the i.

Temporary File Systems

Even though the contents of temporary file systems have the potential to become an important part of future legal proceedings, the volatility concern is not as high here.
Temporary file systems usually stick around for awhile.

The IETF and The Order of Volatility

The Internet Engineering Task Force (IETF) released a document titled, Guidelines for Evidence Collection and Archiving.
It is also known as RFC 3227.
This document explains that the collection of evidence should start with the most volatile item and end with the least volatile item.
So, according to the IETF, the Order of Volatility is as follows:.

What is Order of volatility in computer forensics?

One of the many procedures that a computer forensics examiner must follow during evidence collection is order of volatility.
During the process of collecting digital evidence, an examiner is going to go and capture the data that is most likely to disappear first, which is also known as the most volatile data.

What is the volatility of data in digital forensics?

The volatility of data refers to how long the data is going to stick around– how long is this information going to be here before it’s not available for us to see anymore.
That’s one of the challenges with digital forensics is that these bits and bytes are very electrical.
In some cases, they may be gone in a matter of nanoseconds.
