As a result, PPTP can be a useful alternative or complement to L2TP/IPSec-based VPNs To maintain the proper level of security with PPTP, make sure to implement strong password policy with the use of PPTP SSL VPN: Where Is Its Place in the VPN Market One of the new technologies making a stir in the remote access market is SSL (Secure Sockets Layer) VPN Instead of using standard tunneling protocols such as PPTP or L2TP/IPSec, SSL VPN takes advantage of SSL Internet encap sulation to punch through firewalls over Transmission Control Protocol (TCP) port 443, the port that is usually open to allow for SSL-encrypted communica tions to Web sites.

After this lesson, you will be able to:

The Windows 2000 server must be in a domain, and all user accounts must be configured to have the Save Password As Encrypted Clear Text option enabled Strictly speaking, Internet Explorer 50 or later isn t required, but browser support for Digest authentication isn t universal..

Create a Web Setup Project and use the resulting files to deploy your application. Update and deploy websites in environments with multiple developers and servers by using the Copy Web tool. Precompile websites by using the Publish Web Site tool.

Microsoft does support SSL as part of the overall strategy for remote access, but given the level of security that SSL provides compared to IPSec, it is used as a security option on an application level as opposed to full-blown VPN connectivity The following table breaks down where SSLenabled communications come into play in relation to security and accessibil ity levels Table 4-1 shows the Microsoft strategy for remote access solutions..

Depending on the scenario, a Microsoft .NET Framework website can be extremely easy to deploy. Websites, by default, are entirely file based. This means that the source code is usually deployed to the server. The server then compiles that code when pages are requested. In this scenario, you can deploy a website to a web server by simply copying the files to the correct directory on the server. Even if you are deploying a new version of your site, in most cases you can simply overwrite the old files with the new ones. In addition, if you are creating a website that works on a single server and is file based, there is often no real need to run any type of setup process, edit the registry, or add items to the start menu. Configuration settings are defined with the Web.config file, and application code is contained entirely within the website folder structure. This means that you can deploy the entire website by using the simple xcopy shell command; no special deployment software is required. This simplicity provides a great deal of flexibility in other scenarios, too. If your website is to be deployed to an array of web servers (in which multiple web servers host the same website for scalability and availability), you can use any file-synchronization tool to copy the files between the servers. This allows you to deploy to a master server and have the deployment synchronized across the web farm. If your website has a database, requires special web server configuration, or needs different configuration settings in a release environment, simply copying files will be insufficient. In these cases, publishing a website typically involves:

Configuring an application in IIS. Copying website files to the web server. Setting up a database. Configuring the website with the production database connection. Modifying other configuration settings, such as disabling detailed error messages.

Visual Studio 2010 includes a new Publish Web dialog box that allows you to configure each of these settings once, and then publish a website to one or more web servers with a single click. This section describes this tool in more detail.
