Signing Is for the Bad Days

이 글은 소프트웨어 공급망 보안 강화를 위한 세 가지 주요 프로젝트인 TUF, in-toto, Sigstore를 소개하며, 각각이 레지스트리, 빌드 파이프라인, 키 관리의 위협 모델을 어떻게 다루는지 설명한다. TUF는 레지스트리 침해를 가정하고 역할별 키 분할로 공격을 방어하며, in-toto는 빌드 파이프라인 내 단계별 증명을 통해 무결성을 검증한다. Sigstore는 장기 키 관리를 없애고 단기 인증서와 공개 투명성 로그를 활용해 개발자 부담을 줄이고 보안을 강화한다. 이들 기술은 모두 침해 상황을 전제로 설계되어, 정상 작동 시에는 차이를 느끼기 어렵지만 공격 발생 시 피해를 크게 줄인다.

Signing is for the bad days

TUF, in-toto, and Sigstore only look pointless while nothing is on fire

If your company creates software that manage Software Bill of Material data - SBOMs - then you want to take part of the standardisation of an ECMA standard API for exchanging software transparency artefacts. Join us on November 25th! http://teaintro.eventbrite.com #SPDX #SBOM #INTOTO #CYCLONEDX #OWASP
Introducing the OWASP Transparency Exchange API (TEA)

The industry needs an automated exchange of software transparency artefacts - SBOM, HBOM, VEX and much more. Join us to learn more!

OpenSSF Adds Attestations to SBOMs to Validate How Software is Built

The Open Source Security Foundation (OpenSSF) has recently announced SBOMit, a tool designed to bolster Software Bills of Materials (SBOMs) with in-toto attestations. This development, announced under the OpenSSF Security Tooling Working Group, increases transparency and security in the software development process.

⛓ A new blog post was published about in-toto and SLSA to give a better understanding of how these two are related to each other! If you are interested in learning more about software supply chain security, most probably most of you have come across the terms in-toto attestations and SLSA provenance. But have you ever ask the question to yourself how these two are related to each other, let’s find out! Thanks to
