Guide
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.
,age 2 of 155
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.
,age 3 of 155
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.
, age 4 of 155
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
