What is Application Cybersecurity (AppSec)?

January 8, 2025

Application cybersecurity (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.

What Is It Supposed To Do?

Application Cybersecurity (AppSec) aims to prevent unauthorized access, data breaches & code manipulation by bad actors. 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

The growing significance of AppSec

There are two (2) key truths in modern business operations:

  1. Cyber threats continue to evolve at disturbing rates of growth.
  2. Businesses use more diverse software & applications than ever.

Emerging cybercrime techniques can breach the most secure software applications. Well, as secure as anything can get, anyways. Even a small vulnerability like a configuration issue can cause an enormous data breach if not identified at the beginning of the development cycle.

Now, add in the fact that the majority of apps are cloud native. That a problem, according to research: organizations that adopted cloud-native environments are 4x more likely to have increased concerns — not decreased — over their security posture.

Organizations must incorporate security not only at the network level and at the application level, but in all stages of the development process. It helps to reveal vulnerabilities from the beginning and apply the necessary security control before it could become a series threat to the organization.
