Abstract: A method, system and apparatus are disclosed. According to one or more embodiments, a verifier is provided. The verifier includes processing circuitry configured to obtain a hash algorithm and a fully qualified domain name, FQDN, associated with a virtual network function, VNF, image, determine an identifier for the VNF image based at least on the hash algorithm and the FQDN, perform domain name system security extensions, DNSSEC, resolution of the determined identifier for the VNF image at least in part by requesting at least one attribute of the VNF image using the determined identifier for the VNF image and validating a response associated with the request, and perform validation of the VNF image in response to successful DNSSEC resolution.
