Although the TISLA tool is made as intuitive as possible this is a short manual about how to use the tool.
First of all TISLA is built in Excel and the main file: “00_Assessment__TISLA.xlsm” contains VBA code, so you’ll have to allow marco’s when opening the file to make itt work properly. You can however disable macro’s if you want to. The Excel file will still calculate all results correctly, bu all automated functions like the assisted “Workflow” are not available anymore.
The first tab of the Excel File contains the credits for people that contributed to the tool and a BSD license. Please read the license before using the tool. The use of the TISLA tool is free of charge, but you must meet the licensing terms.
This section in the Excel file contains the same information as on this site under the “Introduction” menue.
Please note that there is a button there to load sample data into the Import files. It is the same data that is in the tool when is downloaded from the site. You can always recoverand reload this sample data if you need to demonstrate the working of this app. The sample data is random data and is not related to any real life situation, it’s just for your convenience if you need some samples.
The “Scores” tab contains the central part of the tool. Here are the results presented , and here there are several buttons that represent the workflow for using the tool. If you want the macros’to be blocked for security reasons you still can use the tool. Calculation of the results does not depend on it, but you will lose all “automated” functionality.
Here you can find the final result and an interpretation of the residual risk in your technical security infrastructure. The risk is related to your companies risk profile that you determined in the “Risk Profile” section.
This section is thepart where all the results from all the main categories and technologies are summarised. You can see the assessment results as a starred ratingfor each technology, for each category and finally the overann result (previous paragraph).
This section shows:
If you follow these buttons top-down you’ll work through the entire file and towards the result.
The above part speaks for itself. We have built the tool in such a way that the results can be printed, exported to PDF or selected and copied into a presentation or other document. Please be aware that pasting the copy as a picture will give the best result in most cases.
The above section is about the OneDrive real time colaboration issue explained in te “Workflow buttons” section. Please enter the local path to the assessment files if clicking this button reports this OneDrive issue.
To get a risk indication related to your companies risk profileyou’ll have to indicate your companies risc profile here.
Each of the six categories has it’s own tab. Each tab has several buttons amongst which is the import button to import files completed by subject matter experts.
The files of the TISLA tool are to be specified as follows.
