You don't need to add anything special to the file; the Script Encoder recognizes the VBS filename extension and deals with the file appropriately To encode the file, simply run SCRENC /f resetpwvbs The Encoder produces a file named ResetPWvbe, which is an encoded VBScript file Here's what it will look like

Encoded scripts can normally be executed just like any other script, with a couple of caveats First, if your scripts don't include <SCRIPT> tags, the filename extensions must be either VBE (for VBScript) or JSE (for Jscript) The different filename extension tells WSH that it needs to decode the script before executing it; if you change the filename extension to VBS (or JS), you receive a runtime error when executing the script When the Encoder goes to work on a file that does use <SCRIPT> tags, it changes the LANGUAGE attribute <SCRIPT LANGUAGE="VBScript"> becomes <SCRIPT LANGUAGE="VBScriptEncode">, for example, giving WSH the cue it needs to decode the script before trying to execute it < Day Day Up >

Review
Script encoding offers a way to protect the source code of your scripts from prying eyes, and a way to ensure that your scripts aren't modified Encoding doesn't provide any kid of runtime security; in other words, by default, Windows Script Host will execute any encoded script it's asked to execute In the next chapter, I'll show you how to lock down WSH so that only your authorized scripts execute in your environment COMING UP Encoding is a great way to secure and protect your scripts In the next chapter, I'll explain how scripting itself can be made safer and more secure Even in this age of script-borne computer viruses, you can still allow administrative scripts to run in your environment After that, Part VI of this book will present several more full-length example scripts to start you toward your own administrative scripts! < Day Day Up >

28 Scripting Security
IN THIS CHAPTER Chances are that you've had to completely disable scripts in your environment, thanks to the number of abusive scripts out there Making scripting a safe part of your environment can be difficult, so in this chapter, I'll give you some pointers for doing so Scripting has two primary security issues associated with it First, the Windows Script Host (WSH) is included with just about every version of Windows since Windows 98 Second, WSH associates itself with a number of filename extensions, making it very easy for users to click an e-mail file attachment and launch unauthorized scripts The knee-jerk reaction of many administrators is to simply disable scripting altogether, which also removes a beneficial administrative tool from the environment In this chapter, I'll focus on ways to address the two primary security issues associated with scripting, helping you to configure a safer scripting environment < Day Day Up >

Why Scripting Can Be Dangerous
"Why can scripting be dangerous " isn't a question many administrators have to ask Something like 70% of all new viruses, according to some authorities, are script based; certainly some of the most devastating viruses, including Nimda, Melissa, and others, propagate at least partially through scripts sent via e-mail Even internally produced scripts can be dangerous, as scripts can delete users, create files, and perform any number in fact, an almost unlimited number of tasks There's little question about the damage scripts can do, making it vitally important that your environment be secured to allow only those authorized, tested scripts that you or your fellow administrators authorize Perhaps the most dangerous aspect of administrative scripting is the easy accessibility scripts have to the system Users can launch scripts without even realizing that they're doing so; a large number of file extensions are registered to the Windows Script Host, and double-clicking any file with one of those extensions launches the script In Windows XP, the default script extensions are JS for JScript files JSCRIPT for Jscript files JSE for Jscript encoded files VBE for VBScript encoded files VBS for VBScript files WSC for Windows Script Components WSF for Windows Script Files Note that older computers may also register VB for VBScript files, SCR for script files, and other extensions; Windows XP cleaned up the filename extension list a bit Don't forget, of course, static HTML files with HTML or HTM filename extensions which can contain embedded client-side script NOTE Other types of scripts exist, such as the Visual Basic for Applications (VBA) embedded into Microsoft Office documents However, I'm going to focus this discussion on scripts associated or executed by the Windows Script Host
The goal of any security program should be to allow beneficial, authorized scripts to run, while preventing unauthorized scripts from running < Day Day Up >
