Cybersecurity exam questions
and answers
American Standard Code for Information Interchange (ASCII)
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
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
The actions that perpetrators take to conceal their locations,
activities, or identities.
,Asymmetric cryptography
Cryptography wherein two keys are used: one to encrypt the
message and another to decrypt it.
Asynchronous transfer mode (ATM)
A high-speed connection technology that uses fixed-length, 53-byte
packets called calls.
Authenticate
To verify the identity of a person, or to verify evidence.
Base transceiver station (BTS)
The part of the cell network responsible for communications
between the mobile phone and the network switching system.
Basic input/output system (BIOS)
The basic instructions stored on a chip for booting up the computer.
Bit-level information
Information at the level of actual 1s and 0s stored in memory or on
the storage device.
Block cipher
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
A special program, such as U-Boot or RedBoot, that is stored in a
special section of the flash memory.
Brute-force attack
An attack in which the attacker tries to decrypt a message by simply
applying every possible key in the keyspace.
Business continuity plan (BCP)
A plan for maintaining minimal operations until the business can
return to full normal operations.
Business impact analysis (BIA)
, An analysis of how specific incidents might impact the business
operations.
Caesar cipher
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. For example, if your
text is "A CAT," and you choose to shift by two letters, your
encrypted text is "C ECV." This is also known as a monoalphabet,
single-alphabet, or substitution cipher.
Carrier
The signal, stream, or data file in which the payload is hidden.
Cell-phone forensics
The process of searching the contents of cell phones.
Chain of custody
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
The type of medium used to hide data in steganography. This may
be photos, video, sound files, or Voice over IP.
Clean room
An environment that has a controlled level of contamination, such
as from dust, microbes, and other particles.
Cloud computing
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
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
