The world runs on web applications, from online banking and remote work applications to streaming services and e-commerce. Developers tirelessly create new apps, iterate existing ones and quickly deliver updates to meet user expectations. Emphasis on the speed of this process makes it challenging for developers to adhere to security principles strictly, and security weaknesses can slip through the cracks. 

These weaknesses, paired with the fact that many web apps by design need to be externally exposed, make them a prime target for malicious actors to try and breach.

And new application exploits emerge every day. Attackers exploit APIs, open-source code, third-party widgets, and access control weaknesses. With the growing dependence of organizations on web apps, the demand for professionals to secure their apps continues to soar. 

If you see yourself working in one of the most in-demand roles in information security and securing web apps that enable today’s global interconnectedness, specializing in web application security can be a perfect career path.

Key skills and requirements for a career in web application security

Web application security is a specialized career path and requires a highly hands-on skillset. To become a web app security engineer, you will need to develop expertise in many critical skills and not only focus on the technical ones. An unrelenting curiosity and passion for lifelong learning are mandatory for anyone seeking to specialize in web application security.

Key skills required for a successful career in web application security include: 

Web app security fundamentals

Before starting your journey to any infosec role, a strong knowledge of the fundamentals of basic IT concepts and some specialized skills are crucial. For web application security, these include fundamentals of web secure coding, web attacker methodology, input validation, understanding the role of assessments, vulnerability discovery, enumeration, and other vital processes in web application security. 

Our fundamental content covered in WEB-100 will provide you with the prerequisite knowledge you will need to begin your training in web application security. Gain the basic skills and confidence needed to advance towards your goals and get comfortable with the tools and technology necessary to begin learning. 

Web app penetration testing

Penetration testing, aka pentesting, is the most commonly used testing technique in web app security. Pentesting is performed by simulating unauthorized attacks, assessing the source code, and manually discovering common vulnerabilities in web apps. Taking the approach of an outside attacker, you work proactively and uncover any possible entryways before they do. A solid understanding of the most common web app risks is crucial for this role. Those most common risks and attack paths you will be emulating in a pentest are: 

    • Broken access control
    • Cross-site scripting (XSS)
    • Insecure design
    • XML external entities (XXE) 
    • Cross-site request forgery (CSRF)
    • Identification and authentication failures 
    • Server-side request forgery (SSRF)

Throughout your career, you will build your methodologies, leveraging industry-wide ones, and work out the best methods and approaches to uncover most vulnerabilities. 

Coding skills

To specialize in web application security, you will need coding experience. Coding is used to create applications, so a working knowledge of the process ensures you can efficiently test and review the security of apps. Organizations will also often look for candidates that can write a quick program and be included in the process of creating secure applications. As most of your time will be spent analyzing source code, knowledge of HTML, CSS, JavaScript, PHP, and ASPX is unavoidable. While you don’t need formal education in application development, being able to quickly grasp new frameworks , languages, and code is a key skill for specializing in web application security.

Hands-on, real-world experience

As we highlighted, web application security is a particularly hands-on infosec domain. Companies and hiring managers will look for a lively portfolio of secure code implementation, web app assessment projects, and real-world experience. As a beginner, one of the best ways to start building your portfolio and gain real-world experience is by participating in bug bounties. You can sign up for many bug bounty platforms and join programs where you will get a chance to find bugs in many of the world’s top organizations and get paid to do so. Bug bounties are also an incredible option to learn as you work. You can also document your findings and showcase them on your website. 

Soft skills

Web app security engineers often work as part of a team, whether a team of consultants, developers, project managers, or other security teams.
