Software Supply Chain
A software supply chain is the components, libraries, tools, and processes used to develop, build, and publish a software artifact. A software bill of materials (SBOM) declares the inventory of components used to build a software artifact, including any open source and proprietary software components. It is the software analogue to the traditional manufacturing BOM, which is used as part of supply chain management. Usage An SBOM allows builders to make sure open-source and third-party software components are up to date and respond quickly to new vulnerabilities. Buyers and other stakeholders can use an SBOM to perform vulnerability or license analysis, which can be used to evaluate and manage risk in a product. While many companies use a spreadsheet for general BOM management, there are additional risks and issues in an SBOM written to a spreadsheet. It is best practice for SBOMs to be collectively stored in a repository that can be part of other automation systems and easily que ...

Artifact (software Development)
An artifact is one of many kinds of ''tangible'' by-products produced during the development of software. Some artifacts (e.g., use cases, class diagrams, requirements and design documents) help describe the function, architecture, and design of software. Other artifacts are concerned with the process of development itself—such as project plans, business cases, and risk assessments. The term ''artifact'' in connection with software development is largely associated with specific development methods or processes e.g., Unified Process. This usage of the term may have originated with those methods. Build tools often refer to source code compiled for testing as an artifact, because the executable is necessary to carrying out the testing plan. Without the executable to test, the testing plan artifact is limited to non-execution based testing. In non-execution based testing, the artifacts are the walkthroughs, inspections and correctness proofs. On the other hand, execution ba ...

Reproducible Builds
Reproducible builds, also known as deterministic compilation, is a process of compiling software which ensures the resulting binary code can be reproduced. Source code compiled using deterministic compilation will always output the same binary. Reproducible builds can act as part of a chain of trust; the source code can be signed, and deterministic compilation can prove that the binary was compiled from trusted source code. Verified reproducible builds provide a strong countermeasure against attacks where binaries do not match their source code, e.g., because an attacker has inserted malicious code into a binary. This is a relevant attack; attackers sometimes attack binaries but not the source code, e.g., because they can only change the distributed binary or to evade detection since it is the source code that developers normally review and modify. In a survey of 17 experts, reproducible builds had a very high utility rating from 58.8% participants, but also a high-cost rating f ...

Supply Chain Management
In commerce, supply chain management (SCM) deals with a system of procurement (purchasing raw materials/components), operations management, logistics and marketing channels, through which raw materials can be developed into finished products and delivered to their end customers. A more narrow definition of supply chain management is the "design, planning, execution, control, and monitoring of supply chain activities with the objective of creating net value, building a competitive infrastructure, leveraging worldwide logistics, synchronising supply with demand and measuring performance globally". This can include the movement and storage of raw materials, work-in-process inventory, finished goods, and end to end order fulfilment from the point of origin to the point of consumption. Interconnected, interrelated or interlinked networks, channels and node businesses combine in the provision of products and services required by end customers in a supply chain. SCM is the br ...

Dependency Hell
Dependency hell is a colloquial term for the frustration of some software users who have installed software packages which have dependencies on specific versions of other software packages. The dependency issue arises when several packages have dependencies on the same ''shared'' packages or libraries, but they depend on different and incompatible versions of the shared packages. If the shared package or library can only be installed in a single version, the user may need to address the problem by obtaining newer or older versions of the dependent packages. This, in turn, may break other dependencies and push the problem to another set of packages. Problems Dependency hell takes several forms: ; Many dependencies : An application depends on many libraries, requiring lengthy downloads, large amounts of disk space, and being very portable (all libraries are already ported enabling the application itself to be ported easily). It can also be difficult to locate all the depende ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Manifest File
In computer programming, a manifest file is a Data file, file containing metadata for a group of accompanying files that are part of a set or coherent unit. For example, the files of a computer program may have a manifest describing the name, Software versioning, version number, Software license, license and the constituent files of the program. The term "manifest" is borrowed from a cargo shipping procedure, where a Manifest (transportation), ship manifest would list the crew and/or cargo of a vessel. Manifest files are similar in nature to Declaration (computer programming) , declaration files in that both specify the expected structure of a computer program to be consumed by another computer program, providing additional information that allow system software, software-defined tools (e.g., compilers, Lint (software), linters), Integrated development environment, development environments, or other developers to understand how to interact with certain resources or code.

Supply Chain Attack
A supply chain attack is a cyber-attack that seeks to damage an organization by targeting less secure elements in the supply chain. A supply chain attack can occur in any industry, from the financial sector, oil industry, to a government sector. A supply chain attack can happen in software or hardware. Cybercriminals typically tamper with the manufacturing or distribution of a product by installing malware or hardware-based spying components. Broadcom#Symantec_enterprise_security, Symantec's 2019 Internet Security Threat Report states that supply chain attacks increased by 78 percent in 2018. A supply chain is a system of activities involved in handling, distributing, manufacturing, and processing goods in order to move resources from a vendor into the hands of the final consumer. A supply chain is a complex network of interconnected players governed by supply and demand. Although supply chain attack is a broad term without a universally agreed upon definition, in reference to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Software Toolchain
A toolchain is a set of software development tools used to build and otherwise develop software. Often, the tools are executed sequentially and form a pipeline such that the output of one tool is the input for the next. Sometimes the term is used for a set of related tools that are not necessarily executed sequentially. A relatively common and simple toolchain consists of the tools to build for a particular operating system (OS) and CPU architecture; consisting of a compiler, a linker, and a debugger. With a cross-compiler, a toolchain can support cross-platform development. For building more complex software systems, many other tools may be in the toolchain. For example, for a video game, the toolchain may include tools for preparing sound effects, music, textures, 3-dimensional models and animation Animation is a filmmaking technique whereby still images are manipulated to create moving images. In traditional animation, images are drawn or painted by hand on transpare ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Software Package Data Exchange
System Package Data Exchange (SPDX, formerly Software Package Data Exchange) is an open standard capable of representing systems with digital components as bills of materials (BOMs). First designed to describe software components, SPDX can describe the components of software systems, AI models, software builds, security data, and other data packages. SPDX allows the expression of components, licenses, copyrights, security references and other metadata relating to systems. The original purpose of SPDX was to improve license compliance, and it has since been expanded to facilitate additional use cases such as supply-chain transparency and security. SPDX is authored by the community-driven SPDX Project involving key industry experts, organizations, and open-source enthusiasts under the auspices of the Linux Foundation. The SPDX specification is recognized as the international open standard for security, license compliance, and other software supply chain artifacts as ISO/IEC 596 ...

Software Composition Analysis
Software composition analysis (SCA) is a practice in the fields of Information technology and software engineering for analyzing custom-built software applications to detect embedded open-source software and detect if they are up-to-date, contain security flaws, or have licensing requirements. Background It is a common software engineering practice to develop software by using different components. Using software components segments the complexity of larger elements into smaller pieces of code and increases flexibility by enabling easier reuse of components to address new requirements. The practice has widely expanded since the late 1990s with the popularization of open-source software (OSS) to help speed up the software development process and reduce time to market. However, using open-source software introduces many risks for the software applications being developed. These risks can be organized into 5 categories: * OSS Version Control: risks of changes introduced by new vers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Open-source Software
Open-source software (OSS) is Software, computer software that is released under a Open-source license, license in which the copyright holder grants users the rights to use, study, change, and Software distribution, distribute the software and its source code to anyone and for any purpose. Open-source software may be developed in a collaborative, public manner. Open-source software is a prominent example of open collaboration, meaning any capable user is able to online collaboration, participate online in development, making the number of possible contributors indefinite. The ability to examine the code facilitates public trust in the software. Open-source software development can bring in diverse perspectives beyond those of a single company. A 2024 estimate of the value of open-source software to firms is $8.8 trillion, as firms would need to spend 3.5 times the amount they currently do without the use of open source software. Open-source code can be used for studying and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
