Describe the process of data normalization

Implementing Cisco Cybersecurity Operations (210-255)

Data normalization is the process of removing duplicate information and increasing the accuracy of the information. In cybersecurity tools like SEIMs can help take IPS or other sources and by normalization make them more usable. The data is also put into a common format or schema even though it comes from multiple types of sources.

Normalization can take one of three forms in cybersecurity, first normal form (1NF), second normal form (2NF) and third normal form (3NF). Each form increases in complexity.
