Net 3.5 security policy administration tool

NET runtime will automatically create it and add the application services schema. However, we don't want to use the aspnet. This modification can be accomplished in one of two ways:. Add the following Roles configuration markup to the Web. The default value is With this configuration markup in place, we are ready to start using role functionality within our application. There are a number of other attributes that affect how the Roles framework associates role information on a user-by-user basis.

We will examine these settings in the Role-Based Authorization tutorial. The Roles framework's functionality is exposed via the Roles class , which contains thirteen static methods for performing role-based operations.

When we look at creating and deleting roles in Steps 4 and 6 we will use the CreateRole and DeleteRole methods, which add or remove a role from the system.

To get a list of all of the roles in the system, use the GetAllRoles method see Step 5. The RoleExists method returns a Boolean value indicating whether a specified role exists. In the next tutorial we will examine how to associate users with roles. In the Role-Based Authorization tutorial we will look at ways to programmatically show or hide functionality based on the currently logged in user's role. Keep in mind that any time one of these methods is invoked, the Roles class delegates the call to the configured provider.

In our case, this means that the call is being sent to the SqlRoleProvider. The SqlRoleProvider then performs the appropriate database operation based on the invoked method. For example, the code Roles. Roles offer a way to arbitrarily group users, and most commonly this grouping is used for a more convenient way to apply authorization rules. But in order to use roles as an authorization mechanism we first need to define what roles exist in the application.

Unfortunately, ASP. In order to add new roles we need to create a suitable user interface and invoke the Roles API ourselves. The good news is that this is very easy to accomplish. NET application designed to assist with viewing and managing your web application's configuration. However, I am not a big fan of the ASP. First, it is a bit buggy and the user experience leaves a lot to be desired. Second, the ASP. NET Web Site Administration Tool is designed to only work locally, meaning that you will have to build your own role management web pages if you need to manage roles on a live site remotely.

For these two reasons, this tutorial and the next will focus on building the necessary role management tools in a web page rather than relying on the ASP. Open the ManageRoles.

At this point, your page's declarative markup should look similar to the following:. Next, double-click the CreateRoleButton Button control in the Designer to create a Click event handler and then add the following code:. Next, the Roles class's RoleExists method is called to determine if the role newRoleName already exists in the system. If the role does not exist, it is created via a call to the CreateRole method. If the CreateRole method is passed a role name that already exists in the system, a ProviderException exception is thrown.

This is why the code first checks to ensure that the role does not already exist in the system before calling CreateRole. You may be wondering what will happen if the user doesn't enter any value into the RoleName TextBox. If the value passed into the CreateRole method is null or an empty string, an exception is raised. Likewise, if the role name contains a comma an exception is raised.

Consequently, the page should contain validation controls to ensure that the user enters a role and that it does not contain any commas. I leave as an exercise for the reader. Let's create a role named Administrators. Visit the ManageRoles. Figure 3 : Create an Administrators Role Click to view full-size image. What happens?

A postback occurs, but there's no visual cue that the role has actually been added to the system. We will update this page in Step 5 to include visual feedback. For now, however, you can verify that the role was created by going to the SecurityTutorials.

Let's augment the ManageRoles. Next, add a method to the page's code-behind class named DisplayRolesInGrid using the following code:. The Roles class's GetAllRoles method returns all of the roles in the system as an array of strings. This string array is then bound to the GridView.

The following code calls this method when the page is first visited, but not on subsequent postbacks. With this code in place, visit the page through a browser. Such apps were created for Windows 7 and even for Windows Vista, where version 3. Once you try to run such an app, you will see a prompt to install the missing component from the Internet.

This method has a number of disadvantages. First of all, it is your Internet traffic, and it can be limited. Secondly, the download process is not reliable and can fail. If your Internet connection is unstable, it turns into hell.

Finally, you can simply work offline. That's why it is important to know how to offline install. You will only need an installation media of Windows 11, such as ISO file , bootable flash drive , or its DVD disk, so no Internet connection will be required.

You are good to go! This will install. NET framework 3. Now you can run any older apps coded in C , VB. Note that. NET 2. To save your time, I have created an easy-to-use simple batch file which automates the above method.

You are done. The file is compatible with both install. The official one comes with install. Tip : You can easily find what versions of the. NET framework software you have installed using the following guide. This permission set specifies the permissions the runtime allows code that satisfies the membership condition to have.

A code group hierarchy, along with its associated named permission sets, defines and maintains each level of security policy. You can use the —user , -customuser , —machine and -enterprise options to set the level of security policy. For more information about security policy and how the runtime determines which permissions to grant to code, see Security Policy Management. To facilitate references to code groups in a hierarchy, the -list option displays an indented list of code groups along with their numerical labels 1, 1.

The other command-line operations that target code groups also use the numerical labels to refer to specific code groups. Named permission sets are referenced by their names. The —list option displays the list of code groups followed by a list of named permission sets available in that policy.

NET Framework that Caspol. If you run the Caspol. Other side-by-side installations of the runtime, if any, are not affected. If you run Caspol. Turning off code access security terminates security checks for all managed code and for all users on the computer. If side-by-side versions of the. NET Framework are installed, this command turns off security for every version installed on the computer. Although the -list option shows that security is turned off, nothing else clearly indicates for other users that security has been turned off.

When a user without administrative rights runs Caspol. When an administrator runs Caspol. The tool has a protective mechanism that prevents policy from being modified in ways that would prevent Caspol. If you try to make such changes, Caspol. You can turn this protective mechanism off for a given command by using the —force option.

Three security configuration files correspond to the three policy levels supported by Caspol. These files are created on disk only when machine, user, or enterprise policy is changed using Caspol. You can use the —reset option in Caspol. In most cases, manually editing the security configuration files is not recommended. But there might be scenarios in which modifying these files becomes necessary, such as when an administrator wants to edit the security configuration for a particular user.

Assume that a permission set containing a custom permission has been added to machine policy. This custom permission is implemented in MyPerm. Both assemblies must be added to the full trust assembly list.

The following command adds the MyPerm. The following command adds the MyOther. The following command adds a child code group to the root of the machine policy code group hierarchy.

The new code group is a member of the Internet zone and is associated with the Execution permission set. The following command changes the permission set in the user policy of the code group labeled 1. The following command changes the membership condition in the default policy of the code group labeled 1.

The membership condition is defined to be code that originates from the Internet zone and the exclusive flag is switched on. The following command changes the permission set with name Mypset to the permission set contained in newpset. Note that the current release does not support changing permission sets that are being used by the code group hierarchy.

The following command causes the user policy's root code group labeled 1 to be associated with the Nothing named permission set. This prevents Caspol. The following command removes the code group labeled 1. If this code group has any child code groups, those groups are also deleted. The following command removes the Execution permission set from the user policy.

The following command shows all code groups of the machine policy that myassembly belongs to. The following command shows all code groups of the machine, enterprise, and specified custom user policy that myassembly belongs to. The following command calculates the permissions for testassembly based on the machine and user policy levels.

Adds an assembly that implements a custom security object such as a custom permission or a custom membership condition to the full trust assembly list for a specific policy level.

This file must be signed with a strong name. You can sign an assembly with a strong name using the Strong Name Tool Sn. Whenever a permission set containing a custom permission is added to policy, the assembly implementing the custom permission must be added to the full trust list for that policy level.

Assemblies that implement custom security objects such as custom code groups or membership conditions used in a security policy such as the machine policy should always be added to the full trust assembly list.

Caution: If the assembly implementing the custom security object references other assemblies, you must first add the referenced assemblies to the full trust assembly list.
