WGU D431 Digital Forensics in Cybersecurity Exam
229 Questions with Verified Answers
A set of codes defining all the various keystrokes you could make, including letters,
numbers, characters, and even the spacebar and return keys. - CORRECT ANSWER
American Standard Code for Information Interchange (ASCII)
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. - CORRECT ANSWER Anonymous
remailing
The actions that perpetrators take to conceal their locations, activities, or
identities. - CORRECT ANSWER Anti-forensics
Cryptography wherein two keys are used: one to encrypt the message and
another to decrypt it. - CORRECT ANSWER Asymmetric cryptography
A high-speed connection technology that uses fixed-length, 53-byte packets called
calls. - CORRECT ANSWER Asynchronous transfer mode (ATM)
To verify the identity of a person, or to verify evidence. - CORRECT ANSWER
Authenticate
,The part of the cell network responsible for communications between the mobile
phone and the network switching system. - CORRECT ANSWER Base transceiver
station (BTS)
The basic instructions stored on a chip for booting up the computer. - CORRECT
ANSWER Basic input/output system (BIOS)
Information at the level of actual 1s and 0s stored in memory or on the storage
device. - CORRECT ANSWER Bit-level information
A form of cryptography that encrypts data in blocks; 64-bit blocks are quite
common, although some algorithms (like AES) use larger blocks. - CORRECT
ANSWER Block cipher
A special program, such as U-Boot or RedBoot, that is stored in a special section of
the flash memory. - CORRECT ANSWER Bootstrap environment
An attack in which the attacker tries to decrypt a message by simply applying
every possible key in the keyspace. - CORRECT ANSWER Brute-force attack
A plan for maintaining minimal operations until the business can return to full
normal operations. - CORRECT ANSWER Business continuity plan (BCP)
An analysis of how specific incidents might impact the business operations. -
CORRECT ANSWER Business impact analysis (BIA)
,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. - CORRECT ANSWER Caesar cipher
The signal, stream, or data file in which the payload is hidden. - CORRECT ANSWER
Carrier
The process of searching the contents of cell phones. - CORRECT ANSWER Cell-
phone forensics
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. - CORRECT ANSWER Chain of custody
The type of medium used to hide data in steganography. This may be photos,
video, sound files, or Voice over IP. - CORRECT ANSWER Channel
An environment that has a controlled level of contamination, such as from dust,
microbes, and other particles. - CORRECT ANSWER Clean room
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. - CORRECT
ANSWER Cloud computing
, 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. -
CORRECT ANSWER Computer forensics
A technique for file system repair that involves scanning a disk's logical structure
and ensuring that it is consistent with its specification. - CORRECT ANSWER
Consistency checking
A method of using techniques other than brute force to derive a cryptographic
key. - CORRECT ANSWER Cryptanalysis
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. - CORRECT ANSWER Curriculum vitae (CV)
The use of electronic communications to harass or threaten another person. -
CORRECT ANSWER Cyberstalking
The act of ensuring the data that is extracted is consistent. - CORRECT ANSWER
Data consistency
The standard holding that only methods and tools widely accepted in the scientific
community can be used in court. - CORRECT ANSWER Daubert standard
Information that helps explain other evidence. An example is a chart that explains
a technical concept to the judge and jury. - CORRECT ANSWER Demonstrative
evidence
