ITSY Key Acronyms/terms Module 7
1. Some of you are new to Information Security (InfoSec) and some are experienced
practitioners looking for some additional education/certification.
2. The biggest part of learning anything new is getting a grasp of the professional
vocabulary and with all things the IT/infosec related acronyms…spoiler alert -- there are
LOT of them.
3. What to do:
a. If it is acronyms spell it out (remember these terms are relevant to cyber security)
b. Provide a brief definition in your own words
c. Use the acronym/term in a few sentences explaining how it is relevant to cyber
security…for instance:
Example: A+ - is a CompTIA certification and is generally consider the first in the series. The A+
certification covers the following areas of IT knowledge/skills: installing, maintaining, customizing, and
operating personal computers. Before I was able to take the CompTIA Network+ exam I had to first take
and pass the A+ exam. Having the A+ certification on my resume helped me land my first computer
repair job.
4. Each acronym/term should require about 3-4 sentences in order to really define and
describe it (remember use your own words please do not just copy and paste from an
internet search).
Term/Acronym
Hierarchical File System – This is the systematic storage system for files, folders, drives, and
other forms of storage in a Mac OS system. It sets up from formatting a drive, with directories
and file systems added to accommodate organized storage of files and applications. HFS
categorizes files into directories and sub-directories with its primary directory at /root.
Apple File System – known as APFS, this is the default file system of macOS as a newer
iteration of HFS. It aids in the organized collation and retrieval of files when they are stored.
APFS works with solid-state and hard drives and on all sorts of devices with storage capacities
running any variant of Apple’s OS.
FMV - Fair Market Value (FMV) is the amount it costs a property to change possession between
a buyer and seller who are willing to trade even when there is no necessity to buy or sell. In this
case, the participants have acceptable information of important facts behind the transaction.
Documentations, appraisals, and record-keeping help to have a detailed evaluation of an FMV.
Stochasticity – is a method in forensics that reconstructs digital activities from different data
values generated from data information and properties. It reads patterns to determine data
movements which can in turn monitor unapproved transactions thereby detecting theft among
other anomalies.
DECAF - Detect and Eliminate Computer Assisted Forensics (DECAF) is a tool designed to
oversee, prevent access, or obscure any digital evidence that Computer Online Forensic Evidence
Extractor (COFEE) tool would want to retrieve. DECAF can delete logs, files, running processes
that identify with COFEE, and spoof MAC addresses to fool forensic procedure.
COFEE - Computer Online Forensic Evidence Extractor is a forensic tool designed by
Microsoft that does live analysis to obtain evidence on a Windows OS machine. It runs on a
script from a removable drive that gathers information activities on a machine from its scanned
files.
National White Collar Crime Center – also known as NW3C is an NGO that is tasked with
fighting cybercrime from an economic point of view. NW3C also provides investigation and
training to law enforcement agencies with backing from Congress.
CRFID - Computational radio frequency identification (CRFID) is a sensory mechanism that
can move exponentially huge amounts of data to a reader within a radio frequency field. It acts as
a communication medium that encodes data that can be sent in bursts to an applicable
transmission reader. CRFID are small and highly functional in a moving capacity for efficient
data mobilization.
Blockchain - is a process of documenting information to make it arduous to alter the system.
Blockchain is a log of transactions that is copied and circulated across a network of computer
systems in the form of a digital journal. The blockchain processes in digital forensic works to
solve the issue of clarity in digital investigation.
