forbidden functions on client-side scripts

["Shimon Silberschlag" <shimons () bll co il>]

Some products that are used as content filters for the HTTP traffic
used by internal users, have the ability to block certain "dangerous"
functions used on client side scripts from getting to the internal
client. Attached is the default function list used by such a product.
Since I'm not a programmer, can someone tell me if this list is
complete/overkill/lacking and what other functions that are
dangerous/benign should I consider adding/dropping from the list. The
list is given for VBscript and Javascript separately.


[VB SCRIPT]
Forbidden
words=CreateObject,GetParentFolderName,GetFolder,GetExtensionName,File
Exist,
GetSpecialFolder,GetFile,Replace,DriveType,ExpandEnviromentString,Open
textfile,CreateTextRange,
OpenAsTextStream,DeleteFile,CopyFile,RegWrite


[JAVA SCRIPT]
Forbidden
words=CreateObject,ActiveXobject,GetParentFolderName,GetFolder,GetExte
nsionName,Replace,Opentextfile,DeleteFile,CopyFile,RegWrite

TIA,
