American Standard Code for Information Interchange (ASCII) - correct answer A
set of codes defining all the various keystrokes you could make, including letters,
numbers, characters, and even the spacebar and return keys.
Anonymous remailing - correct answer The process of sending an email message
to an anonymizer. The anonymizer strips identifying information from an email
message before forwarding it with the anonymous mailing computer's IP address.
Anti-forensics - correct answer The actions that perpetrators take to conceal
their locations, activities, or identities.
Asymmetric cryptography - correct answer Cryptography wherein two keys are
used: one to encrypt the message and another to decrypt it.
Asynchronous transfer mode (ATM) - correct answer A high-speed connection
technology that uses fixed-length, 53-byte packets called calls.
Authenticate - correct answer To verify the identity of a person, or to verify
evidence.
Base transceiver station (BTS) - correct answer The part of the cell network
responsible for communications between the mobile phone and the network
switching system.
Basic input/output system (BIOS) - correct answer The basic instructions stored
on a chip for booting up the computer.
Bit-level information - correct answer Information at the level of actual 1s and 0s
stored in memory or on the storage device.
Block cipher - correct answer A form of cryptography that encrypts data in
blocks; 64-bit blocks are quite common, although some algorithms (like AES) use
larger blocks.
Bootstrap environment - correct answer A special program, such as U-Boot or
RedBoot, that is stored in a special section of the flash memory.
Brute-force attack - correct answer An attack in which the attacker tries to
decrypt a message by simply applying every possible key in the keyspace.
Business continuity plan (BCP) - correct answer A plan for maintaining minimal
operations until the business can return to full normal operations.

Business impact analysis (BIA) - correct answer An analysis of how specific
incidents might impact the business operations.
Caesar cipher - correct answer The method of cryptography in which someone
chooses a number by which to shift each letter of a text in the alphabet and
substitute the new letter for the letter being encrypted. This is also known as a
monoalphabet, single-alphabet, or substitution cipher.
Carrier - correct answer The signal, stream, or data file in which the payload is
hidden.
Cell-phone forensics - correct answer The process of searching the contents of
cell phones.
Chain of custody - correct answer The continuity of control of evidence that
makes it possible to account for all that has happened to evidence between its
original collection and its appearance in court, preferably unaltered.
Channel - correct answer The type of medium used to hide data in
steganography. This may be photos, video, sound files, or Voice over IP.
Clean room - correct answer An environment that has a controlled level of
contamination, such as from dust, microbes, and other particles.
Cloud computing - correct answer The practice of delivering hosted services over
the internet. This can be software as a service, platform as a service, or
infrastructure as a service.
Computer forensics - correct answer The use of analytical and investigative
techniques to identify, collect, examine, and preserve computer-based material
for presentation as evidence in a court of law.
Consistency checking - correct answer A technique for file system repair that
involves scanning a disk's logical structure and ensuring that it is consistent with
its specification.
Cryptanalysis - correct answer A method of using techniques other than brute
force to derive a cryptographic key.

Curriculum vitae (CV) - correct answer An extensive document expounding one's
experience and qualifications for a position, similar to a résumé but with more
detail. In academia and expert work, it is usually used rather than a résumé.
Cyberstalking - correct answer The use of electronic communications to harass or
threaten another person.
Data consistency - correct answer The act of ensuring the data that is extracted is
consistent.
Daubert standard - correct answer The standard holding that only methods and
tools widely accepted in the scientific community can be used in court.
Demonstrative evidence - correct answer Information that helps explain other
evidence. An example is a chart that explains a technical concept to the judge and
jury.
Denial-of-service (DoS) attack - correct answer An attack designed to overwhelm
the target system so it can no longer reply to legitimate requests for connection.
Digital evidence - correct answer Information that has been processed and
assembled so that it is relevant to an investigation and supports a specific finding
or determination.
Digital forensics - correct answer Computer forensics expanded to include
smartphones, smart watches, and other current and forthcoming digital media
and devices.
Disaster recovery plan (DRP) - correct answer A plan for returning the business to
full normal operations.
Disk forensics - correct answer The process of acquiring and analyzing
information stored on physical storage media, such as computer hard drives or
smartphones.
Disk Operating System (DOS) - correct answer A command-line operating system.
Disk striping - correct answer Distribution of data across multiple disk sectors to
improve speed (also called RAID 0).
