Using Connection Manager
Connection Manager Overview
If you want to configure clients to connect to a RRAS server, you can use the Connection Manager to do this. Using the network connection properties to configure clients to connect to a RRAS server works well in situations where you need to configure a small number of clients, and when the default security settings are being utilized.
Connection Manager is a Windows application and client dialer included in Windows 2000, Windows XP Professional, and Windows Server 2003 that you can use to allow a client to establish virtual private network (VPN) connections and dial-up connections to a RRAS server. The advanced features of Connection Manager enable you to pass preconfigured connections to network users. These advanced features are evident in the Connection Manager Administration Kit (CMAK) and Connection Point Services (CPS). Both local connections and remote connections to the service provider through a network of access points are supported by Connection Manager. As mentioned, for secure connections over the Internet, VPN connections can be established using Connection Manager.
With the Connection Manager Administration Kit (CMAK), you can perform the following functions:
- Configure a large numbers of clients by creating an executable file which can be deployed to your users by means of a distribution package.
- Manage dial-up and VPN Connection Manager service profiles.
- Customize Connection Manager to suit the requirements of your organization.
- Configure system policies for connections.
- Configure restrictions for connections.
- Configure executable files that run automatically when a user attempts to establish a connection.
- Import existing connection settings so that they can be modified, and then distribute these modifications.
When users run the distribution package, or executable file, a dial-up connection or VPN connection using the required authentication methods and security settings is established. It is even possible to automatically distribute the executable file by using a Group Policy object. Any modifies to security settings can be done at a later stage by running the Connection Manager Administration Kit (CMAK) once more, and then simply distributing the executable file for users to run.
The main advantages and features of Connection Manager are listed here:
- Users can run more than one Connection Manager service profile at the same time.
- Connection Manager can also be used when users share computers. A user does not need to provide user credentials for each connection.
- You can customize the following components within Connection Manager so that it reflects the identity of the organization:
- Icons and graphics
- Help
- Phone book information
- Messages
- Users can run more than one Connection Manager service profile at the same time.
- The Connection Manager Administration Kit (CMAK) Wizard can be used to automatically create a service profile so that users can run Connection Manager to establish VPN and dial-up connections. The service profile takes the form of an executable file which can be distributed using either of the following methods:
- Download to the client.
- Distributed via compact disc.
- You can include custom functionality or programs that execute during the connections process. For instance, you can run a program when the user logs on, and when the user logs off.
- You can configure monitored applications to automatically disconnect once the application is closed.
- Connection logging, terminal window support and enhanced ISDN support are a few additional features of Connection Manager.
- Access points can be used to save commonly utilized connection settings. Connection Manager includes help for Access Points and Dialing Rules.
Planning for Creating New Connection Manager Service Profiles
The Connection Manager Administration Kit (CMAK) Wizard consists of a number of steps or pages that need to be completed to create a new Connection Manager service profile. You therefore need to plan upfront which items are going to be specified when you run the CMAK Wizard.
The online CMAK Guide specifies six phases for creating a new Connection Manager service profile. This process is detailed here:
- Planning phase: Typical issues that should be determined in the planning phase are:
- Determine the connection which should be established.
- Determine which customizations you want – graphics, Phone book information, and so forth.
- Determine which programs should be applied at the connection establishment process.
- Developing custom elements phase: This is when you should create all custom graphics, icons, and all other elements which you want to include for the new Connection Manager service profile.
- Running the CMAK Wizard phase: The Connection Manager Administration Kit (CMAK) Wizard is initiated and run to create the new Connection Manager service profile for the connection.
- Preparing for delivery phase: The new Connection Manager service profile can be distributed via CDROM, floppy disk, Web site, or a network share. It can also be downloaded to the client.
- Testing phase: It is important to test all new packages before users are allowed to download these packages.
- Providing support phase: It is recommended that you define a support strategy once the new Connection Manager service profile is distributed to users.
Addressing Connection Manager Security Concerns
Because the Connection Manager Administration Kit (CMAK) Wizard enables Administrators to configure connection properties for creating connections to the network, a few a security loopholes can be accidentally created as well.
A few common Connection Manager security concerns are listed here:
- There is the risk of an unauthorized user establishing a connection and using it. This can basically occur when a computer can be accessed by multiple users.
- For users to run the existing installation of CMAK, they have to belong to the Power Users group. The service profiles created by the CMAK Wizard are text files. Because of this, a user that has access to the text files can simply use a text editor to change the text files created by the CMAK Wizard.
- When a Connection Manager service profile includes confidential information, there is a threat that an unauthorized user can intercept this information and exploit it.
A few strategies that can be used to address Connection Manager security concerns are listed below:
- You can require that users utilize the more current Windows operating systems that support the user certificates feature of Connection Manager.
- Ensure that only those users who are authorized can download and obtain the Connection Manager service profile.
- For a computer that is utilized by more than one user, ensure that users cannot utilize the Remember Password feature to store the password for the connection. To disable the Remember Password feature, configure the HideRememberPassword option. The HideRememberPassword option can be accessed in the last page of the CMAK Wizard by clicking Edit Advanced Options.
Using the Connection Manager Administration Kit (CMAK) Wizard
The Connection Manager Administration Kit (CMAK) is implemented through the CMAK Wizard. The CMAK Wizard is used to create an executable file which can be distributed to users so that they can establish virtual private network (VPN) connections and dial-up connections to a RRAS server.
