A method for multi-source cloud-infrastructure vulnerability management includes receiving cloud-element information related to a cloud-based element in a cloud environment. The method also includes receiving first vulnerability information from a first vulnerability source and receiving second vulnerability information from a second vulnerability source. Cloud-element context information is also received about the cloud-based element from the cloud environment. A multiple-source vulnerability database is then generated from both the first vulnerability information and from the second vulnerability information. The cloud-element information and the cloud-element context information are then evaluated using the multiple-source vulnerability database to generate a vulnerability assessment.
