ISC2 – CC 2026 Exam
Questions with 100% Correct
Answers | Latest Update
Application Server - ANSWER ✔✔A computer responsible for hosting
applications to user workstations. NIST SP 800-82 Rev.2
Asymmetric Encryption - ANSWER ✔✔An algorithm that uses one
key to encrypt and a different key to decrypt the input plaintext.
Checksum - ANSWER ✔✔A digit representing the sum of the correct
digits in a piece of stored or transmitted digital data, against which later
comparisons can be made to detect errors in the data.
,Ciphertext - ANSWER ✔✔The altered form of a plaintext message so
it is unreadable for anyone except the intended recipients. In other
words, it has been turned into a secret.
Classification - ANSWER ✔✔Classification identifies the degree of
harm to the organization, its stakeholders or others that might result if an
information asset is divulged to an unauthorized person, process or
organization. In short, classification is focused first and foremost on
maintaining the confidentiality of the data, based on the data sensitivity.
Configuration management - ANSWER ✔✔A process and discipline
used to ensure that the only changes made to a system are those that
have been authorized and validated.
Cryptanalyst - ANSWER ✔✔One who performs cryptanalysis which is
the study of mathematical techniques for attempting to defeat
cryptographic techniques and/or information systems security. This
includes the process of looking for errors or weaknesses in the
implementation of an algorithm or of the algorithm itself.
Cryptography - ANSWER ✔✔The study or applications of methods to
secure or protect the meaning and content of messages, files, or other
information, usually by disguise, obscuration, or other transformations of
that content and meaning.
,Data Loss Prevention (DLP) - ANSWER ✔✔System capabilities
designed to detect and prevent the unauthorized use and transmission
of information.
Decryption - ANSWER ✔✔The reverse process from encryption. It is
the process of converting a ciphertext message back into plaintext
through the use of the cryptographic algorithm and the appropriate key
for decryption (which is the same for symmetric encryption, but different
for asymmetric encryption). This term is also used interchangeably with
the "deciphering."
Degaussing - ANSWER ✔✔A technique of erasing data on disk or
tape (including video tapes) that, when performed properly, ensures that
there is insufficient magnetic remanence to reconstruct data.
Digital Signature - ANSWER ✔✔The result of a cryptographic
transformation of data which, when properly implemented, provides the
services of origin authentication, data integrity, and signer non-
repudiation. NIST SP 800-12 Rev. 1
Egress Monitoring - ANSWER ✔✔Monitoring of outgoing network
traffic.

, Encryption - ANSWER ✔✔The process and act of converting the
message from its plaintext to ciphertext. Sometimes it is also referred to
as enciphering. The two terms are sometimes used interchangeably in
literature and have similar meanings.
Encryption System - ANSWER ✔✔The total set of algorithms,
processes, hardware, software, and procedures that taken together
provide an encryption and decryption capability.
Hardening - ANSWER ✔✔A reference to the process of applying
secure configurations (to reduce the attack surface) and locking down
various hardware, communications systems, and software, including
operating system, web server, application server, application, etc.
Hardening is normally performed based on industry guidelines and
benchmarks, such as those provided by the Center for Internet Security
(CIS).
Hash Function - ANSWER ✔✔An algorithm that computes a
numerical value (called the hash value) on a data file or electronic
message that is used to represent that file or message and depends on
the entire contents of the file or message. A hash function can be
considered to be a fingerprint of the file or message. NIST SP 800-152
