# HG changeset patch # User kfraser@xxxxxxxxxxxxxxxxxxxxx # Node ID 947e09f90b3bbb900a80b7e15d9987f2d1e04566 # Parent 3fae79942240a02218381cd33490548b5cf6c12f [ACM] A wxPython GUI tool for sHype/ACM in Xen. It is used and described in the user guide to demonstrate how to quickly create, enforce, and test workload protection policies in Xen. The tool is aimed to improve usability of sHype/ACM for Xen.It is included in a single file to make it easy to try it out on different platforms (it inherits the look and feel of the base platform). It is tested on Linux and Windows. Please read the new user guide section about how to start and use the tool (section 10.2). Requirements: python (www.python.org), wxPython (www.wxpython.org or try 'yum install wxPython').

For this +purpose you enter the names of workload types that you want to assign to +domains and resources. You can also define groups of workload types that +should not run on the same system simultaneously for any reason; such groups +are called Runtime Exclusion Sets. Please refer to the Xen User Guide for +more information. + +This tool will create a unique security label for each workload type. Every +domain and resource must be labeled so that the hypervisor system can correctly +identify the associated workload type and control the sharing among domains +in a way that keeps different workload types confined from each other. +This tool ensures two things: + +1. The created security policy includes a distinctive label for each workload +type defined in step 1 below. These labels must later be assigned to Domains +and Resources to enable Xen to enforce the confinement. + +2. The created security policy includes access control rules that are enforced +by the Xen Hypervisor (independently of the guest Domains) and guarantee +that: +<BLOCKQUOTE>(i) Domains that are assigned the same workload type label can +share (communicate, +use common resources) without restriction through the hypervisor. Their +interoperation can still be constraint by the domains (domain-internal +means).</BLOCKQUOTE> +<BLOCKQUOTE>(ii) Domains that are assigned different workload type labels cannot share, +i.e., cannot communicate or use common resources. Independently enforced +by the hypervisor, the domains cannot overrule this decision.</BLOCKQUOTE> +<BLOCKQUOTE>(iii) Once a Domain labeled with a workload type of a Runtime Exclusion +Rule is running, no other domain labeled with another workload type of +the same Runtime Exclusion Rule can start. This holds for all Runtime Exclusion +Rules.</BLOCKQUOTE> +While all workloads share common hardware resources, the core hypervisor +isolation and virtualization in combination with the Xen access control +policy ensure that, e.g., viruses in one workload type cannot infect other +workload types and that secrets used within one workload type cannot leak +into another workload type. Currently the Xen access control enforcement +covers domains, local storage resources, and the local virtual network +interfaces. Protecting sharing through the open network is subject of ongoing +work; such protection must currently be setup manually using IP filtering +rules in Domain0. + + +<H2>Step 1</H2> +The first step of creating a workload protection policy is to determine +names for the different workload types. The left panel offers the means +to define and and manage workload type definitions. + +A workload can be an organization name (coarse-grained type), e.g. a corporate +realm such as IBM or PepsiCo. An organization can be refined to describe +independent functional groupings within the organization, such as IBM.Financing +or Pepsi.Payroll. Use the <New Org> button on the left panel +to create a new organization workload. To refine such a workload, right-click the +organization and chose <Add Department>. You can add multiple +departments to an organization but you do not have to add any. + +This tool will create a separate label name for each organization and for +each department workload. The policy will be computed so that there is +no sharing between organizations or departments by default. IBM, IBM.Financing, +Pepsi, and Pepsi.Payroll will by default not be able to share in this simple +policy example. You can introduce controlled sharing by refining the policy, +which is beyond the scope of this help. + +As an example, define the four organizations PepsiCo, CocaCola, Avis, Hertz. +Define department workloads Payroll, HumanResources and Financing for Avis +and CocaCola, and PepsiCo. + +<H2>Step 2</H2> +In this second step, we enter those workload types that should not run +simultaneously on the same hardware platform. There might be multiple reasons +for this, e.g., imperfect resource control. + +As an example, we will create a policy that guarantees that PepsiCo workloads +and CocaCola workloads never run simultaneously on the same platform: + +1. Select the PepsiCo organization on the left panel by left-clicking it.. + +2. Press the <Ctrl>-Key and then select CocaCola organization by +left-clicking it while keeping the <Ctrl>-Key pressed.. + +3. Click the <Create run-time exclusion rule from selection> +button and enter a name for this Run-time Exclusion rule (e.g., RER1). The name is +for your reference only. It has no impact on the policy. On the right panel, a run-time +exclusion rule with the chosen name appears. + +The interpretation of the rule is as follows: If a domain labeled PepsiCo +is running, then another domain labeled CocaCola cannot start on the same +system and the other way round. This also holds for departments of PepsiCo +and CocaCola (organizations dominate their departments). If PepsiCo or +PepsiCo.Payroll etc. are running, then a domain with label CocaCola or +CocaCola.Payroll etc. cannot start. If you want to restrict concurrency +between specific subtypes, then you must create a Run-time Exclusion rule +that specifies the department workload types. To exclude only CocaCola.Payroll +and PepsiCo.Payroll from running simultaneously the Run-time Exclusion +rule must be formed using Coca.Cola.Payroll and PepsiCo.Payroll, not their +organizations. Consequently it does not make sense to add both an organization +and any of its departments to the same Run-time Exclusion rule because +any department is already covered by its organization (this tool will not +allow it). + +You can create multiple Run-time Exclusion rules, all of which will be +enforced simultaneously by the hypervisor. You do not need to define any +Run-time Exclusion rule if you do not find it necessary. You can add or +delete workload types from Run-time Exclusion rules using the <Add> +and <Del> buttons associated with the rule. The <Add> +button adds the workload types selected in the left panel to the Run-time +Exclusion rule. The <Del> button deletes the workload types selected +in the associated Run-time Exclusion rule from the rule. + +<H2>Step 3</H2> +Now that we have defined the workloads and Run-time Exclusion rules, we +can save the workload definition for later reference or refinement. Select +the File->Save Workload +Definition as.. menu entry and choose a file name. + +Please use the File->Save as Xen ACM Security Policy.. menu entry and choose a policy +name to create a Xen Workload Protection +security policy from the current workload definition. To simplify the succeeding +steps, please use a name of the form "example.chwall_ste.NAME" +where you merely replace "NAME" with a policy name of your choice. +Save the policy under the name proposed by the tool in the proposed directory +if you are using this tool in your Xen environment. Otherwise, you need +to copy the resulting file into your Xen environment to the directory +"/etc/xen/acm-security/policies/example/chwall_ste/". + +This tool creates policies for the Xen Chinese Wall and Simple Type Enforcement +policy. The Xen access control policy in general is more expressive and +this tool only uses a small subset of the possible configurations. + +Where to go from here. + +Before the new policy can be activated, we need to translate the policy into a representation that +Xen and the Xen-tools can work with. To this end, in your Xen environment, please issue the command +xm makepolicy example.chwall_ste.NAME where NAME must be replaced by the name you chose +for your policy in step 3 above. Then, we need to make the policy available to the Xen hypervisor. In +your Xen environment, please issue the command xm cfgbootpolicy example.chwall_ste.NAME +to install the policy for the next reboot. If the command cannot find the correct boot title, then you +can manually install it as described in the xm man page. + +Finally, reboot your security-enabled Xen environment. Please refer to the xm man page for how to enable +Xen security. After reboot, you can use xm labels type=any to list all the created workload l +abels. Use the xm addlabel command to assign workload type labels to the associated domains +and resources. + +From here, please check the Xen user guide. +</BODY> +</HTML> +""" + +#=============== main ===== + +def main(): + global app + app = ezApp(0) + if len(sys.argv) in [2]: + app.Load(sys.argv[1]) + app.MainLoop() + print "Goodbye" + +if __name__ == '__main__': + main() + +#==== end of file _______________________________________________ Xen-changelog mailing list Xen-changelog@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-changelog
