SIEM visualization (5-8)

To create a new visualization we go on the drop menu and select "Dashboard" Click "Create Visualization"

A window opens with 4 important notices.

1. A filter option that allows us to filter the data before creating a graph. For example:

2. This field indicates the data set (index) that we are going to use. It is common for data from various infrastructure sources to be separated into different indices, such as network, Windows, Linux, etc. In this particular example, we will specify windows* in the "Index pattern".

3. This search bar provides us with the ability to double-check the existence of a specific field within our data set, serving as another way to ensure that we are looking at the correct data.

4. Lastly, this drop-down menu enables us to select the type of visualization we want to create.
