Module Name:
secmgrp.h
Abstract:
This module contains definitions necessary to write a
Security Manager Extension DLL (affectionately refered to
as a Smedly).
Author:
Jim Kelly (JimK) 22-Sep-1994
Revision History:
None.
ReadMe:
Smedly stands for Security Manager Extension Dll
- - - --
(I threw in the "y" in "smedly" because "smedl" didn't sound right).
Loading Smedlys
---------------
The Security Manager will load and utilize all the smedlys listed in
the registry key value:
Key: \Registry\Machine\Lsa\Security Manager
Value: Extension Dlls [REG_MULTI_SZ]
This REG_MULTI_SZ registry key value, if present, is expected to contain
a list of smedly DLL names (without the .dll) separated by semicolons.
For example, to load the standard microsoft smedly it would contain "mssmedly".
If "mssmedly" and "Cairosm" were to both be loaded, then the value would contain
"mssmedly; cairosm".
If the key is not present, or for some reason there are no smedlys specified
in the key, then the standard Microsoft smedly is loaded and used.
Areas and Items
---------------
A smedly is responsible for administering 1 or more named security
"Areas".
Each Area has 1 or more named security "Items". An Item is expected
to be an individually administrable security attribute (such as "who
may shutdown a system").
It is expected that similar security Items are grouped in a single
security Area. For example, security Items dealing with System Access
are in a single Area.
Administration Views
--------------------
The Security Manager provides two views for administering a system's
security:
Item-list view - in this view, each item is listed in a
spreadsheet format. In fact, this view is also refered
to as "spreadsheet view". The Security Manager is
responsible for providing all the dialogs related to
this view.
Item-dialog view - in this view, a full dialog is provided
to administer a single Item. It is expected that this
dialog will provide more infomation than can be shown
in Item-List view, perhaps with help messages that provide
more insight into the items purpose and use.
Area view - in this view, the smedly responsible for the
view is asked to display dialogs that allow the user
to administer all the items in that Area at one glance
(or in a few dialoges, if necessary).
For each Item supported by a smedly, the smedly must provide information
that allows the Security Manager to present the Item in Item-List view.
If the Item is complicated, then it may not be editable in Item-List view,
which a smedly may also indicate to the Security Manager.
For each Area a smedly supports the smedly must tell the Security Manager
whether or not the smedly provides an Area View capability. If not, then
the Items in that area are administrable only using Item-List and Item-dialog
view (assuming at least one of those views is supported).
Data Structures
---------------
The main data structures linking the security manager and its smedlys together are:
SECMGR_CONTROL - There is exactly one of these structures. It provides information
about the current state of the security manager to smedlys when called.
This also contains the dispatch table of routines provided by the Security Manager
for use by smedlys.
SECMGR_SMEDLY_CONTROL - There is one of these for each smedly loaded. It describes
the areas and items of the smedly to the security manager. This also contains
the dispatch table of routines provided by the smedly for use by the Security
Manager.
SECMGR_AREA_DESCRIPTOR - There is one of these for each area supported by a smedly.
They are arranged in an array fashion within the SECMGR_SMEDLY_CONTROL structure.
SECMGR_ITEM_DESCRIPTOR - There is one of these for each item in a security area.
They are arranged in an array fashion within the SECMGR_AREA_DESCRIPTOR structure.
So, the chicken-wire data structure representing each smedly looks like:
+-------------------------+

SmedlyNewSecurityLevel( VOID )
Routine Description:
This function is called when a new system security level has
been selected. This may should cause a Smedly to go out and
re-evaluate its recommended values for its areas.
Arguments
None.
Return Values:
TRUE - The routine completed successfully. Item values and recommendations
may or may not have changed.
FALSE - The routine failed to complete successfully. GetLastError()
contains further information about the cause of failure.

SmedlyReportFileChange(
IN BOOL ReportFileActive,
IN DWORD Pass
)
Routine Description:
This function is called to notify a smedly that a new report
file has been activated. This gives the smedly an opportunity
to put some header information into the report file.
This is a 2-pass operation. The first pass is done before the
security manager places summary list of features and their current
settings in the report file. The second pass is made after this
summary has been logged. Smedlys should resist printing too many
details until pass 2.
If there is no new report file active, this call will only be made
once (skipping the second pass).
Arguments
ReportFileActive - If TRUE indicates that a new report file has been opened.
If FALSE, indicates that a report file has been closed, and another was
not opened.
Pass - Indicates which pass this call relates to. This will have a value of
either 1 or 2. This value is only set if ReportFileActive is TRUE.
Return Values:
None.

SmedlyInitialize(
IN PSECMGR_CONTROL SecMgrControl,
OUT PSECMGR_SMEDLY_CONTROL *SmedlyControl
)
Routine Description:
This function is called when the smedly is loaded.
It receives a security manager control block. This
block contains revision level information and a dispatch
table of security manager routines available for use
by the smedly.
It returns a smedly control block describing the areas
and items supported by the smedly, as well as a dispatch
table of routines available for use by the security
manager in future interactions with the smedly.
Arguments
SecMgrControl - Points to a Security Manager control block
for use by the smedly. This block will not change once
smedly has returned, and therefore, it may be referenced
directly in the future (rather than having to copy it).
SmedlyControl - Upon successful return, this parameter must contain a
pointer to a smedly control block provided by the smedly.
Return Values:
TRUE - The call completed successfully.
FALSE - Something went wrong. GetLastError() contains
details on the exact cause of the error.
