American Standard Code for Information Interchange (ASCII) - 🧠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 - 🧠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 - 🧠ANSWER ✔✔The actions that perpetrators take to conceal their
locations, activities, or identities.
Asymmetric cryptography - 🧠ANSWER ✔✔Cryptography wherein two keys are
used: one to encrypt the message and another to decrypt it.

Asynchronous transfer mode (ATM) - 🧠ANSWER ✔✔A high-speed connection
technology that uses fixed-length, 53-byte packets called calls.
Authenticate - 🧠ANSWER ✔✔To verify the identity of a person, or to verify
evidence.
Base transceiver station (BTS) - 🧠ANSWER ✔✔The part of the cell network
responsible for communications between the mobile phone and the network
switching system.
Basic input/output system (BIOS) - 🧠ANSWER ✔✔The basic instructions stored
on a chip for booting up the computer.
Bit-level information - 🧠ANSWER ✔✔Information at the level of actual 1s and 0s
stored in memory or on the storage device.
Block cipher - 🧠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 - 🧠ANSWER ✔✔A special program, such as U-Boot or
RedBoot, that is stored in a special section of the flash memory.
Brute-force attack - 🧠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) - 🧠ANSWER ✔✔A plan for maintaining minimal
operations until the business can return to full normal operations.
Business impact analysis (BIA) - 🧠ANSWER ✔✔An analysis of how specific
incidents might impact the business operations.
Caesar cipher - 🧠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
Mono alphabet, single-alphabet, or substitution cipher.
Carrier - 🧠ANSWER ✔✔The signal, stream, or data file in which the payload is
hidden.

Cell-phone forensics - 🧠ANSWER ✔✔The process of searching the contents of
cell phones.
Chain of custody - 🧠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 - 🧠ANSWER ✔✔The type of medium used to hide data in steganography.
This may be photos, video, sound files, or Voice over IP.
Clean room - 🧠ANSWER ✔✔An environment that has a controlled level of
contamination, such as from dust, microbes, and other particles.
Cloud computing - 🧠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 - 🧠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.
