This is the first post in these series where I would like to discuss just how many SBOMs we actually… Continue reading Why a Single SBOM is Never Enough

Here I would like to describe a model on how we organize storage of release metadata for technology products. This methodology is a part of new Reliza’s project (to be announced soon). This may refer to both software or hardware or a mix of the two. I Problem Statement Various regulator requirements are either mandating… Continue reading Release Metadata Organization Model
