William Ryan A few years ago, my company implemented a fairly straightforward client/server application in ASP.NET. The application was implemented and customers were happy, but we received some new security guidelines from the government that involved implementing a new firewall. The application connected directly to the database from the Web server, which forced us to poke a hole in the firewall and opened up some potential security concerns. We decided that we should use .NET remoting to implement an application server. The Web server would only talk to the application server and the application server would talk to the database. This way, the database could never be accessed directly from the Web server, so even if the Web server were ever compromised, the attack surface would be greatly reduced. This solution was the single best enhancement that was made in the application, and we have used .NET remoting extensively since then.

On the surface, calling a method using .NET remoting might not look any different from calling any other traditional method. However, looks are very deceiving in this case because the mechanics of calling a remote method differ greatly (and for the most part, these mechanics are hidden from the developer) from traditional method invoca tion or even Web method invocation. The following are some of the major differences:

AIA specifies the location from which clients can download a copy of the CA certificate. The AIA default location is on the CA computer. Because this CA will be offline, you must change the publication location of the AIA to the network so that it is accessible by clients. The location must be changed before certificates are issued because the AIA location is published on the certificate. Use the example syntax, and enter a URL that maps to a location on a Web server on the network. Figure 2-14 shows the process.

Each time you call a remote method, the server must be contacted so it can pro cess the request. With the exception of methods decorated with the OneWay attribute (discussed later), the developer cannot know at the time of invocation whether or not the method will complete successfully. Much more care must be taken with respect to the passing of parameters and the size of the returned value because remoting methods involve network traffic and, depending on bandwidth availability, operations that would otherwise be trivial might cause performance concerns.

Make sure the new URL is selected, and click the Include In The AIA Exten sion Of Issued Certificates check box. Don t forget this step! The location of the AIA must be available, and for it to be used, the information must be pub lished on the certificate.

These issues are quite serious and need to be considered in depth before using .NET remoting. For instance, assume that your application had a Person object with a FirstName and LastName property, both of which are of type String. Provided that the prop erties were set properly, each could be referenced from calling code without any possibility of an exception being thrown. Yet if the object was remote, several factors, such as a server failure, would cause the method to fail. Similarly, on client machines, developers often take copious amounts of random access memory (RAM) on client machines for granted. Passing large objects around often makes sense, and most peo ple take the ability to do so for granted. However, in remoting scenarios, each param eter that is passed in, as well as each value that is returned, consumes bandwidth. This bandwidth might not be readily available, and things that used to work fine might suddenly start performing sluggishly (or worse, failing).

This is the shell object. This is the string indicating the name of the value to read. strName must be a fully qualified path to a key or value and begin with one of the root keys: HKCR, HKCU, HKLM, or HKU. Example (VBScript)

After this lesson, you will be able to:

Remove the old URL, which points to the local computer. The root CA will not be accessible on the network. Add an AIA LDAP location, and make sure it s included in the published cer tificates. The default LDAP location on a stand-alone server that is not a mem ber server will not have this item checked, as it makes no sense for that server. However, because the typical hierarchy design will include enterprise subordinate CAs, the root CA certificate should be available in Active Direc tory. Don t forget to obtain a copy of the root CA certificate and publish it in the Active Directory on the Web server. Remove the file location, because the root CA will not be on the network where this could be accessed.
