Application Security
Application Security (AppSec) is the practice of designing, developing, and deploying software with security measures to protect applications from threats, vulnerabilities, and attacks. It encompasses processes, tools, and methodologies to ensure confidentiality, integrity, and availability of data and functionality. This includes secure coding practices, vulnerability management, and security testing throughout the software development lifecycle.
Developers should learn Application Security to build resilient software that protects sensitive user data, complies with regulations (e.g., GDPR, HIPAA), and prevents costly breaches. It is essential for web applications, mobile apps, and APIs handling financial transactions, personal information, or critical infrastructure. Mastering AppSec helps in identifying and mitigating common vulnerabilities like SQL injection, cross-site scripting (XSS), and insecure authentication.
