Application security and infrastructure security are two different aspects of cybersecurity that focus on securing different elements of an organization's technology ecosystem.
Application security refers to the measures and practices taken to protect software applications from vulnerabilities, threats, and unauthorized access. It involves securing the code, data, and functionality of applications throughout their lifecycle, from development to deployment and maintenance. The primary goal of application security is to ensure that applications are resilient against attacks and that sensitive information remains protected.
Infrastructure security focuses on securing the underlying technology stack, including the hardware, networks, operating systems, and cloud services that support the organization's IT infrastructure. It involves protecting the physical and virtual resources that applications and data rely on. Infrastructure security measures are aimed at preventing unauthorized access, ensuring availability, and protecting against various threats.
