What is Application Security (AppSec)?

January 8, 2025

Application cybersecurity, also known as AppSec, is the process of protecting software from threats throughout its lifecycle. It involves a variety of techniques, tools, and practices to identify, fix, and prevent vulnerabilities in applications.  AppSec is a crucial part of cybersecurity and software engineering. It’s an ongoing process that includes security considerations during application design and development, as well as systems and approaches to protect applications after they’re deployed. AppSec aims to prevent unauthorized access, data breaches, and code manipulation. It also ensures the confidentiality, integrity, and availability of applications and their data. Some examples of application security techniques include: 

  • Secure coding practices
  • Vulnerability assessments
  • Security testing
  • Web application firewalls
  • Bot management tools
  • DDoS mitigations
