What concept focuses on the protection of applications and data?

Application Security is the concept that emphasizes securing applications and the data they handle throughout their lifecycle. This includes implementing measures to prevent attacks such as unauthorized access, data breaches, and various vulnerabilities that can be exploited by malicious actors.

Application Security involves a range of practices, including secure coding practices, regular software updates, applying patches, intrusion detection, and utilizing firewalls and encryption to safeguard sensitive information. These practices ensure that both the applications themselves and the data they manage are protected from potential threats, thereby maintaining the integrity, confidentiality, and availability of data.

In contrast, Systems Architecture deals with the design and structure of complex systems, focusing more on the arrangement of components rather than security specifics. GIS Software pertains to geographic information systems and is more about spatial data management and analysis rather than protection. Scripting Basics covers the fundamental aspects of writing scripts but does not specifically address the security of applications or data.

Thus, Application Security is the most relevant answer to the question about focusing on the protection of applications and data.
