Description: Data Security Testing is a set of procedures designed to ensure that information stored in computer systems is protected against unauthorized access, alterations, or losses. These tests are fundamental in software development, as they ensure that applications and systems meet required security standards. They include vulnerability assessments, penetration testing, and access control verification. Through these tests, the aim is to identify and mitigate potential risks that could compromise the integrity, confidentiality, and availability of data. The importance of these tests lies in the increasing amount of sensitive data that organizations handle, as well as the need to comply with data protection regulations and standards. In a digital environment where cyber threats are becoming increasingly sophisticated, Data Security Testing becomes an essential practice to safeguard information and maintain user and customer trust.
