Introduction

●  CosmicCount.xltm is an Excel tool ●  It runs on Office 2013 and uses VBA Macros ●  Its source is open and accessible to all users; no password protection; no

warranty ●  Sheets are protected by a password

➨  Password is stored in the Utilities module ➨  If you unprotect sheets, and change structure or defined names with Names

Manager, functionality will be affected ➨  Excel sheets serve as a database; they are known to the database interface only and

can be replaced by any other DB ➨  Structure diagrams are rendered on a blank Excel worksheet

About Using this Tool

You can adapt colors, line characteristics, but not preset shape types ("the smiley remains a smiley...")on this sheet. All newly created objects will be affected. You can specify labels, add a description (shownon the data sheets only), add and delete user devices, application devices, functional processes, and Persistent Data storages on the top row. Then you create Data Movements , either by clicking position lines, first origin, then destination, or using the "New.." button in the respective dialog form.

Selected objects are highlighted, also selected origins and (applicable) destination position lines.

Counting checks four COSMIC rules pertaining to Data Movements; below there is an option to enforcethe existence of triggers for functional processes, and data group definitions for data movements.If youset these options to True, you must specify all triggers, and all data groups, that pertain to functionalprocesses and data movements in order to include them into your COSMIC count.. If you do not wantsuch rigor in your count, you can set the options below to False. Data Moverments that add to the countare color-marked; if they loose their colored origin diamond, they do not qualify for a data movementaccording COSMIC rules. The colors are indicative for the data movement type and set on this sheet

When selecting a group for a data movement, you cannot select a group that already had been used thesame way before, between same origin and destination. Such groups will not be offered for selection.

Table Input in Excel

●  All tables can be edited without using forms ➨  Tables have Add Row, Del Row and Validate buttons

•  Default for adding rows is bottom of table •  Missing data results in no validation and no graphical display

➨  You need to refer to the unique names for linking data ➨  There are consistency checks similar to graphical input:

•  Deleting objects of interest also deletes data movements •  Deleting data movements also deletes triggers

➨  A full refresh event occurs when activating Counting Sheet ➨  Select cells to indicate where to insert or delete table rows ➨  Keep sheets always protected

●  You cannot add or delete rows outside the table interior ➨  Note that there are hidden first and last rows in the table

Import and Export

●  Import and Export copy the following data tables ➨  Data Groups ➨  Objects of Interest ➨  Data Movements ➨  Triggers ➨  Functional User Requirements

●  References (e.g., origin, destination for data movements) refer to line numbers instead of ‘Name’ used in data tables

●  Two buttons on the ‘How to Use’ sheet allow exporting to, and importing from, a file in the XLSX format ➨  Export/import functionality be extended to XML as soon as a schema file is available

Limitations

●  Structure Diagrams contain ➨  Looped Data Movements, same origins and destinations

•  Not yet supported ➨  Conditional areas with execution under condition only

•  Not yet supported ●  Counting several applications with COSMIC

➨  You can link to other application counts but a count consolidation sheet is not available

➨  You need to customize a consolidation sheet •  Use the following Excel range names to access count results:

CFP, CFP_E , CFP_X, CFP_R , CFP_W •  On sheet ‘Data Movements’ for each counting workbook

Installation

●  Copy the template to your Microsoft template directory ➨  Usually C:\Users\<username>\AppData\Roaming\Microsoft\Templates

•  Or where appropriate

➨  Trust macros – in expert mode: •  File – Options – Trust Center Settings – Macro Settings:

Enable all macros (not recommended by Microsoft) ➨  Trust macros – in enterprise mode:

•  Install corporate digital certificate in VBA •  Then enable digitally signed macros only

●  No other resources are used ➨  Except standard Office 2013 libraries including PowerPoint

Troubleshoot with Office 2010 or earlier

●  Depending what your machine has, it might seem impossible to run the VBA macros, because Office 2013 now references another security package then before

●  You have to manually re-link VBA libraries – something very difficult because Excel won’t you let in but maintains some strange VBA compiler error messages

●  Recommended procedure: ➨  Delete all the VBA code displayed with error ➨  Usually you have to do that twice, until VBA allows you to access VBA – Tools – References ➨  Set the references in VBA – Tools – References correctly, as explained next slide ➨  Now undo the code deletions – the VBA code should now compile

Office 2013 à 2010

●  There is a major change regarding security policy ➨  In Office 2013, authorization is via a new library:

•  Microsoft Office.NET Private Object Library

➨  It used to be: •  Microsoft Office 14 Authorization Control Type Library

●  You have to manually switch References in VBA!
