(G1) - least diverse -> least entropy So maybe increasing entropy (disorder) would increase security? - multiple kinds of software, hosts, etc But that seems chaotic and thus insecure? Entropy on a specific graph - hosts can have some number of vulns - edges represent the vulns a host has - cannot remove all edges by assumption - hosts always have some - increase entropy -> more disorder in edges Adding new kinds of s..."
