When a software package disappears from a security inventory, the first question should be what changed: the software, the resource, or the ability to observe it.<\/p>\n

On November 6, 2026, AWS introduced an SBOM inventory in Security Hub<\/a>, bringing package and version information from Amazon Inspector into a central view. A software bill of materials, or SBOM, records the components found in software or on a resource. The new view can make it easier to locate a package across a fleet.<\/p>\n

Ask for the coverage record alongside the package list<\/h2>\n
