TISGSecurity Component

Unit
ISGSec

Description

The TISGSecurity Component provides security facilities for your application.  Security is initialized 
by the developer by creating security files for an application. For a detailed look at installation see 
Tasks.

There are two version of the security.dll. One is a development version which includes the routines to 
create the security files and another which omits these calls.  The second version is delivered with 
the application so that security files cannot be recreated by an intruder.

The security files are Foxpro files which are encoded so that user names and passwords cannot be 
read.

Security is provided by adding constants which describe some access level then specifying which 
users have rights to which constants. The developer can then test for a users right to an access 
constant before allowing access.  Although simple in design, elaborate schemes can be developed 
for granting access. Security based on resource access or levels can be designed.

Security.dll - What Is It?

The ISG security DLL is a dynamic-link library which provides security functionality to an application 
with only a few function calls (seven in all).  By using the security dll, developers can reduce 
development time.  Using a dll also allows the same security code to be used with most Windows 
development systems.  In order to reduce memory requirements, when multiple applications are 
using the security dlls, only one copy of the dll is loaded.  Each applications, however, is using a 
separate set of encoded security files.

Additional Installation Required
1)	Install the TISGSecurity component as directed in the the User's Manual of  Delphi. The
isgsec.dcu file should be selected in the install component dialog.  The source code is
not supplied.  After installation, the component is located in the [system] tab.

2)	Optionally, you can merge the component's help file using the supplied keyword file.
Again, instructions are in the Delphi Documentation (HelpInst from the Delphi Group).
Make sure that the help file is in the path.

3)   The DbSetup utility program is used to create the security databases in a directory.
