ISC2 CC Exam Questions With 100% Correct Answers

ISC2 CC Exam Questions With 100% Correct Answers Application Server - answerA computer responsible for hosting applications to user workstations. NIST SP 800-82 Rev.2 Asymmetric Encryption - answerAn algorithm that uses one key to encrypt and a different key to decrypt the input plaintext. Checksum - answerA 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 - answerThe 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 - answerClassification 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 - answerA process and discipline used to ensure that the only changes made to a system are those that have been authorized and validated. Cryptanalyst - answerOne 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 - answerThe 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) - answerSystem capabilities designed to detect and prevent the unauthorized use and transmission of information. Decryption - answerThe 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 - answerA 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 - answerThe 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 - answerMonitoring of outgoing network traffic. Encryption - answerThe 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 - answerThe total set of algorithms, processes, hardware, software, and procedures that taken together provide an encryption and decryption capability. Hardening - answerA 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 - answerAn 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 Hashing - answerThe process of using a mathematical algorithm against data to produce a numeric value that is representative of that data. Source CNSSI Information Sharing - answerThe requirements for information sharing by an IT system with one or more other IT systems or applications, for information sharing to support multiple internal or external organizations, missions, or public programs. NIST SP 800-16 Ingress Monitoring - answerMonitoring of incoming network traffic. Message Digest - answerA digital signature that uniquely identifies data and has the property such that changing a single bit in the data will cause a completely different message digest to be generated. NISTIR-8011 Vol.3 Operating System - answerThe software "master control application" that runs the computer. It is the first program loaded when the computer is turned on, and its main component, the kernel, resides in memory at all times. The operating system sets the standards for all application programs (such as the Web server)
