Package name is the identifier used to label a software package in a package manager, repository or operating system. It lets tools reference the package for installation, updates, dependency resolution and removal, distinct from the human-readable display name or version number.
What package names do in software distribution
Package names are the stable labels package managers use to identify software for install, update, dependency resolution, and removal. They are operational identifiers, not marketing names, and they anchor every downstream action the tool performs.
Why package names matter for dependency management
A package name is the lookup key in repository metadata and local inventory. If the name is wrong, ambiguous, or reused across different ecosystems, the manager may resolve the wrong artifact, miss a dependency, or install something unintended.
This matters most in environments that rely on automated build, deploy, and patch workflows, where name-based resolution drives repeatable outcomes. For open-source packages, the broader supply-chain context is why ecosystems such as OpenSSF focus so heavily on package integrity and trust signals.
How package names relate to repositories and versions
The package name identifies the package family, while the version identifies a specific release and the display name may vary for human readability. That separation is important because tools query by name first, then compare version constraints, signatures, provenance, and dependency rules.
In practice, the same package name can appear in multiple repositories, distributions, or namespaces, so the name alone is not enough to guarantee trust. Security teams should treat package identity as a combination of name, source, version, and provenance rather than assuming the label is unique across the ecosystem.
Failure modes that come from weak package naming discipline
Weak naming discipline creates room for confusion, typosquatting, dependency confusion, and accidental installation of the wrong artifact. Once a malicious or mistaken package is selected by name, the toolchain may propagate that choice into development, CI, or production environments.
Package names can also be abused when users rely on familiar labels without checking the repository of origin. A package can look legitimate at a glance while still being a counterfeit, an abandoned clone, or a malicious replacement.
Practical checks for safer package selection
Teams should verify the exact package name against the intended repository, confirm publisher provenance, and distinguish package identity from the human-facing product name. That verification is especially important in automated pipelines where a single naming error can scale quickly across many systems.
When packaging, publishing, or approving dependencies, keep internal naming conventions consistent and document the canonical source of truth for each package family. Clear naming reduces operator error and makes reviews, inventory, and incident response much faster.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
CIS Controls v8, SLSA, NIST SP 800-53 Rev 5 and OWASP ASVS set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| CIS Controls v8 | CIS-15 — Service Provider Management | Package names often identify third-party software sources that need supplier trust checks. |
| Recommendation — Track package sources and validate supplier trust before approving dependencies. | ||
| SLSA | Supply Chain Levels for Software Artifacts | Package names point to artifacts whose provenance and integrity must be preserved in the software supply chain. |
| Recommendation — Tie package selection to provenance and integrity checks across the build pipeline. | ||
| NIST SP 800-53 Rev 5 | SA-12 — Supply Chain Protection | Package names are part of software acquisition and distribution where supply-chain controls apply. |
| Recommendation — Apply supply-chain controls to verify the origin and integrity of packaged software. | ||
| OWASP ASVS | V15 — Secure Coding and Architecture | Package naming affects dependency selection and software composition choices in application builds. |
| Recommendation — Review dependency identifiers carefully to prevent unsafe or unintended package inclusion. | ||
