Domain 5 Flashcards
Application server
A computer responsible for hosting applications to user workstations
Asymmetric encryption
An algorithm that uses one key to encrypt and a different key to decrypt the input plain text
Check s u m
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
Cipher text
The altered form of a plain text message so it is unreadable for anyone except the intended recipients. In other words, it has been turned into a secret
Classification
Classification identifies the degree of harm to the organization, at stakeholders or others that might result if an information asset is divulged into an unauthorized person process or organization
Configuration management
A process and discipline used to ensure that the only changes made to a system are those that have been authorized and validated
Cryptanalyst
One who performs crimp Krypt analysis which is the study of mathematical techniques for attempting to defeat cryptographic techniques and/or Information Systems security
Cryptography
The study your 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 meeting
Data loss prevention or DLP
System capabilities designed to detect and prevent the unauthorized use and transmission of information
Decryption
The reverse process from encryption. It is the process of converting a ciphertext message back into plain text through the use of 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 deciphering
Degasing
A technique of erasing data on disc or tape including videotapes.com when perform properly, ensures that there is an insufficient magnetic remnants to reconstruct data
Digital signature
The result of a cryptographic transformation of data which when used properly provides the services of origin authentication, data integrity, and sign or non-repudiation
Egress monitoring
Monitoring of outgoing Network traffic
Encryption
The process and act of converting the message from its plain text to ciphertext. Sometimes it is also referred to as insiphering. The two terms are sometimes used interchangeably in literature and have the same meaning
Encryption system
The total set of algorithms, processes, hardware, software, and procedures that taken together provide an encryption and decryption capability
Hardening
A reference to the process of applying secure configurations to reduce the attack surface and locking down various hardware, communication systems, and software including operating system, web server, application server, Etc hardening is normally performed based on industry guidelines and benchmarks, such as those provided by the center for Internet Security or CIS
Hash function
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
Hashing
The process of using a mathematical algorithm against data to produce a numeric value that is representative of that data
Information sharing
The 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
Ingress monitoring
Monitoring of incoming Network traffic
Message Digest
A 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
Operating system
The software Master Control application that runs the computer.
Patch
A software component that, when installed, directly modifies files or device settings related to a different software component without changing the version number or release details for the related software component
Patch management
The systematic notification identification, deployment, installation and verification of operating system and application software code revisions these revisions are known as patches
