Ch4 Flashcards
Application programming interface (API)
A set of routines, standards, protocols, and tools for building software applications to access a web-based software application or web tool.
Bit
The most essential representation of data (zero or one) at Layer 1 of the Open Systems Interconnection (OSI) model.
Broadcast
Broadcast transmission is a one-to-many (one-to-everyone) form of sending internet traffic.
Byte
The byte is a unit of digital information that most commonly consists of eight bits.
Cloud computing
A model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. NIST 800-145
Community cloud
A system in which the cloud infrastructure is provisioned for exclusive use by a specific community of consumers from organizations that have shared concerns (e.g., mission, security requirements, policy and compliance considerations). It may be owned, managed and operated by one or more of the organizations in the community, a third party or some combination of them, and it may exist on or off premises. NIST 800-145
De-encapsulation
The opposite process of encapsulation, in which bundles of data are unpacked or revealed.
Denial-of-Service (DoS)
The prevention of authorized access to resources or the delaying of time-critical operations. (Time-critical may be milliseconds or it may be hours, depending upon the service provided.) Source: NIST SP 800-27 Rev A
Domain Name Service (DNS)
This acronym can be applied to three interrelated elements: a service, a physical server and a network protocol.
Encapsulation
Enforcement of data hiding and code hiding during all phases of software development and operational use. Bundling together data and methods is the process of encapsulation; its opposite
process may be called unpacking, revealing, or using other terms. Also used to refer to taking any set of data and packaging it or hiding it in another data structure, as is common in network protocols and encryption.
Encryption
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.
File Transfer Protocol (FTP)
The internet protocol (and program) used to transfer files between hosts.
Fragment attack
In a fragment attack, an attacker fragments traffic in such a way that a system is unable to put data packets back together.
Hardware
The physical parts of a computer and related devices.
Hybrid cloud
A combination of public cloud storage and private cloud storage where some critical data resides in the enterprise’s private cloud while other data is stored and accessible from a public cloud storage provider.
