2.3 <strong>IT</strong> <strong>Baseline</strong> <strong>Protection</strong> Modelling<br />

Once the required information is available from the <strong>IT</strong><br />

structure analysis and the assessment of protection<br />

requirements, the next major task is to model the <strong>IT</strong> assets<br />

under consideration with the aid of the existing modules of<br />

the <strong>IT</strong> <strong>Baseline</strong> <strong>Protection</strong> <strong>Manual</strong>. <strong>The</strong> outcome of this<br />

exercise is an <strong>IT</strong> baseline protection model of the <strong>IT</strong> assets<br />

which is made up from different modules of the manual, in<br />

some cases with the same modules being used several times<br />

over, and maps the security-relevant aspects of the <strong>IT</strong> assets<br />

onto specific modules and vice versa.<br />

It makes no difference to the <strong>IT</strong> baseline protection model created whether the <strong>IT</strong> assets consist of <strong>IT</strong><br />

systems already in service or whether the <strong>IT</strong> assets in question are still at the planning stage. However,<br />

the model may be used differently depending on whether the assets are already in use or not.<br />

- <strong>The</strong> <strong>IT</strong> baseline protection model for <strong>IT</strong> assets already in service identifies the standard security<br />

safeguards that are relevant through the modules used. It can be used in the form of a test plan for<br />

carrying out a target versus actual comparison.<br />

- By contrast, the <strong>IT</strong> baseline protection module for a planned set of <strong>IT</strong> assets constitutes a design<br />

concept. It specifies via the selected modules which standard security safeguards must be<br />

implemented on entry into service of the <strong>IT</strong> assets.<br />

<strong>The</strong> diagram below clarifies the role of the modelling and its possible outcomes:<br />

Typically a set of <strong>IT</strong> assets currently in use will contain not only elements which have already been<br />

implemented but also elements which are still at the planning stage. <strong>The</strong> resulting <strong>IT</strong> baseline<br />

protection model then contains both a test plan and also elements of a design concept. <strong>The</strong> <strong>IT</strong> security<br />

concept will then be based on a combination of the <strong>IT</strong> security safeguards which are identified during
