Using code access security for application Isolation. Overview. If you host multiple ASP. NET Web applications on a shared Web server, you need to consider application isolation. For example, how can you ensure that individual applications will not affect one another at runtime? How can you prevent a single rogue or badly written application from consuming critical system level resources on the server that keeps other applications from running properly? The issue is particularly significant for Internet Service Providers (ISPs) who host large numbers of applications from different companies.

In a hosting scenario, it is essential to ensure that the installation of a new application cannot adversely impact the operation of existing applications. There are a number of ways in which application isolation can be achieved.

The available options vary depending on the version of the . NET Framework and the version of the operating system that you run on the Web server. If you are running . NET Framework version 1. This application isolation is achieved by restricting an application from to access different types of resources such as the file system, registry, event log, Active Directory, databases, network resources, and so on.

In addition, Windows Server 2. Internet Information Services 6. IIS 6) application pools that enable multiple applications to run in separate IIS worker process instances. Process isolation is not possible on Windows 2.

Web applications run in a single instance of the ASP. NET worker process, with application domains providing isolation. The Table 2. 0. 1 summarizes the various options for application isolation that are available on Windows 2. Windows Server 2.

On Windows 2. 00. Web applications run in a single instance of the ASP.

NET worker process (Aspnet. Each application resides in its own application domain that provides a degree of isolation for managed code. The Windows 2. 00. IIS 5 architecture is shown in Figure 2. Figure 2. 0. 1. ASP.

NET architecture on Windows 2. IIS 5. The components of the architecture depicted by Figure 2. Table 2. 0. 2. Table 2. Components of the Windows 2. ASP. NET Architecture. Component. Description. Inetinfo. exe. The main IIS process.

A Windows service that runs under the local SYSTEM account. Aspnet. It is responsible for forwarding requests to the ASP. NET worker process through an asynchronous named pipe. It also starts the worker process and performs health monitoring. The ISAPI extension contains no managed code and performs no request processing itself.

Aspnet. Runs inside Inetinfo. Aspnet. Hosts multiple Web applications in separate application domains that are used to provide isolation. Generally one instance per server, although on multi- processor servers, a Web garden mode supports multiple identical processes with an affinity for a given processor. It is not possible to separate specific Web applications into different processes.

This requires IIS 6 and Windows Server 2. It can run on the Web server or on a remote machine (required for Web farm scenarios). It runs under the local ASPNET account, although a custom account can be used, configured via the Services snap- in.

ASP. NET Architecture on Windows Server 2. On Windows Server 2. IIS 6 allows multiple processes to be used to host separate Web applications. This is shown in Figure 2.

Note   IIS 6 supports a backwards compatibility mode that, in turn, supports the IIS 5 ASP. NET worker process model. Figure 2. 0. 2. ASP. NET architecture on Windows Server 2. IIS 6. Compared to the ASP. NET architecture under Windows 2. Windows Server 2.

IIS worker process instances (W3wp. Web applications. By default, these run using the NT Authority\Network. Service account, which is a least privileged local account that acts as the computer account over the network. A Web application that runs in the context of the Network Service account presents the computer's credentials to remote servers for authentication. Configuring ACLs for Network Service.

Configuring an access control list (ACL) for the Network Service account varies for local and remote machines. If you want to grant access to the Network Service account on the local machine, add the Network Service account to an ACL. If you want to grant access to the Network Service account on a remote machine, add the Domain. Name\Machine. Name$ account to an ACL. Note   Do not confuse the Network Service account with the Network built- in group, which includes users who were authenticated across the network.

The main components of the architecture depicted by Figure 2. Table 2. 0. 3. Table 2. Components of the Windows Server 2.

ASP. NET Architecture. Component. Description. Aspnet. Runs inside W3wp. W3wp. exe. The IIS worker process that contains the managed code ASP. NET processing engine. The URL space can be arbitrarily divided among different W3wp. IIS 6 application pools.

A Web garden mode is also supported. Requests are routed to the W3wp. Http. sys which runs in kernel mode. By default, the process runs under the Network Service account but can be configured.

Aspnet. It can run on the Web server or on a remote machine (required for Web farm scenarios). Runs under the Network Service account but can be configured using the Services snap- in. Isolating Applications by Identity. You can isolate ASP. NET Web applications from an operating system identity standpoint by controlling the account identity used to run each application. If each application uses a separate fixed account identity, you can authorize and audit each application separately. Note   If you host an ASP.

NET Web application built using the . NET Framework version 1.

For more information, see Microsoft Knowledge Base article 3. You can use this approach if your application authenticates users independently of IIS, for example, by using Forms or Microsoft Passport authentication. In these scenarios, you can isolate the application by using a fixed anonymous account. Once the caller is authenticated and roles are checked, the trusted server model can be used for downstream resource access, where the configured anonymous account provides the trusted identity. To support this approach, the application's virtual directories in IIS must support anonymous access and a separate anonymous account must be configured for each application.
