Segmentation
In relation to data security, data segmentation is the process of placing data into different locations based on who should be able to access the data. For example, it would be a good practice to place employee PII in a different location (like a different database) from the data contained in press releases.
Data segmentation may also be a requirement for compliance regulations. For example, a regulation may require that specific data never leave a country. The reason is typically that laws govern the use of this data, and once the data leaves the country, those laws no longer have effect. In this case, data segmentation may be related to the region in which you store the data. See the “Impact of Laws and Regulations” section in this chapter for further details.
