A method for sequencing virtual machines in a shared pool of configurable network computing resources comprises sequencing at least one computing element for one or more virtual machines into a respective one or more profiles. Each virtual machine corresponds to a respective profile. The method also includes storing the one or more profiles in a security database and identifying a first group of virtual machines and a second group of virtual machines. The first group of virtual machines corresponds to a security incident in the shared pool of configurable network computing resources. The method also comprises comparing profiles of the first group of virtual machines with profiles of the second group of virtual machines and determining an alteration plan based on the comparison of profiles of the first group with profiles of the second group. The alternation plan is related to the profiles of the second group of virtual machines.
