How Can Developers Use OWASP to Write Secure Coding?

Application security breaches have become increasingly common, with over 14 mega-breaches impacting more than 1 million records in the last year alone. The average breach takes 9 months to identify and 75 more days to contain, racking up massive costs.

In light of this threat landscape, secure coding is no longer optional – it’s imperative for developers to incorporate security practices into their design, coding, and testing processes. However, understanding where to start can be daunting. This is where OWASP comes into play.

OWASP (Open Web Application Security Project) is an open-source project dedicated solely to application security awareness and guidance. Through its community-built resources, OWASP helps developers implement secure coding systematically.

Let’s explore the key ways developers leverage OWASP to write more secure code.

Grasping the Highest Risks

The first step is understanding the most problematic risks. OWASP’s Top 10 list documents the current top 10 web application vulnerabilities statistically found to be most exploited.

For instance, the 2021 edition calls out injection attacks that allow attackers to relay malicious code through inputs. Another common risk is broken authentication that permits unauthorized access to user accounts.

By grasping these high probability + high impact risks, developers can focus their efforts on mitigating the vulnerabilities that matter most. The Top 10 offers a risk-based approach rather than diluting attention across dozens of issues.

Meeting Security Requirements

Once developers know what to protect against, specific implementation guidance is needed. OWASP provides developers with the Application Security Verification Standard (ASVS) – a list of application security requirements and controls.

For example, it offers precise input validation rules to prevent injection attacks based on data types. For authentication, ASVS requires proper password storage, multi-factor options, logout, and account recovery mechanisms.

Developers can use ASVS as a baseline security checklist when architecting, coding, and testing apps. This moves secure coding from vague theory into actionable protections.

Benchmarking Maturity

Most development teams don’t instantly achieve security mastery. It takes time to evolve capabilities.

This is where OWASP’s Software Assurance Maturity Model (SAMM) helps. It allows benchmarking of current practices across domains like design, implementation, and testing.

Based on the maturity assessment results, organizations can create a multi-year roadmap to systematically boost security posture through improvements like:

  • Adopting threat modeling in architecture

  • Automating secure code reviews

  • Expanding penetration testing scope

SAMM provides a structured way to progress security capabilities over multiple release cycles.

Solving Security Challenges

In addition to its flagship Top 10, ASVS, and SAMM resources, OWASP offers targeted solutions for security challenges through its project portfolio.

For example, developers can tap into language-specific guidance to prevent vulnerabilities like SQL injection or cross-site scripting (XSS) in code for:

  • Java

  • .NET

  • PHP

  • Python

Guidance is also available on securing popular web frameworks like React, Vue, Angular, and newer ones like Remix.

For cloud-based development, OWASP provides recommendations tailored to platforms like AWS, Azure, and Google Cloud.

This breadth of readily available resources makes OWASP a versatile toolbox. Developers can find security solutions for their specific coding needs rather than reinventing the wheel.

Wrap Up

In summary, OWASP gives developers a structured approach to implement modern application security practices by:

  • Focusing on highest probability threats

  • Meeting baseline requirements

  • Benchmarking and improving maturity over time

  • Tapping into proven solutions for diverse technologies

With concrete standards powered by community expertise, OWASP helps developers write code that users can trust. Its resources transform secure coding from broad theory into practical reality.
