Arturo is attempting to protect the database (data) of an information system (IS).
<h3>What is an information system?</h3>
An information system (IS) can be defined as a set of computer systems, that is typically used to collect, store, and process data, as well as the dissemination of information, knowledge, and the distribution of digital products.
In Cybersecurity, there are two (2) main techniques that can be used to check data when inputted in an information system (IS) and these include:
Data validation is a type of check which is primarily performed by a software program (application) to make sure that the data which is entered into an information system (IS) is allowable and sensible.
This ultimately implies that, any data that is not allowed or sensible are rejected and discarded by the computer system.
In conclusion, we can deduce that Arturo is attempting to protect the database (data) of an information system (IS).

Due to the different speeds of P and S waves, a single seismometers can determine the distance to an earthquake. So, for a single station, the localization is any point on a circle around the station. With 2 stations, you'll have two circles that intersect at two points. The 3rd station is needed in order to determine which of the 2 points is the actual earthquake.</span>
