Injection flaws have sat inside the OWASP Top 10's top three vulnerabilities for years, and this course tackles them from both sides: attacking and defending. Taught by an instructor with experience on both blue and red security teams, it focuses on how injection vulnerabilities show up specifically in Java and Spring Boot applications.

Attack Types Covered

  • SQL injection
  • NoSQL injection
  • LDAP injection
  • Log injection
  • CSV injection

How You'll Learn It

Rather than just reading about each vulnerability, you'll build a vulnerable web application yourself — complete with a login module using Thymeleaf, Bootstrap, and Spring Security form login — and then exploit it. From there, the course applies a defense-in-depth approach, layering multiple fixes onto each vulnerability instead of relying on a single patch.

It's aimed at Java web developers who want to write more secure code, and at anyone interested in ethical hacking and web application security more broadly.

As part of the blue and red security teams,I have a practical knowledge and I am here to help you learn the injection vulnerability in detail.

In this course, you will focus on different type of injection attacks;

  • SQL Injection

  • NoSQL injection

  • LDAP injection

  • LOG injection

  • CSV injection

Ethical hacking and Web application security are the two important subjects of Cyber Security field and having practical knowledge about Injections will enable you to better understand the security concepts and make a quick start.

In this course you will follow defense-in-depth principle and apply multiple solutions to each vulnerability to secure the web application in multiple layers.

You will follow a hands-on approach. You will not only learn how to exploit an application using different kind of injection attacks, but also develop the vulnerable applications from scratch in which you will have a common web login module with Thymeleaf and Bootstrap for a basic front-end, with Spring security form login authentication & authorisation, and with separate applications for SQL, NoSQL and LDAP injections.

The applications will be developed using Java, Spring boot and Spring Data along with the most used data sources, such as PostgreSQL for SQL Injection, MongoDB for NoSQL injection and OpenLDAP for LDAP injection.

In each section there will be;

  • Development of the vulnerable web application using Java, Spring boot and Spring security

  • Hacking of the application with various attack payloads and with Ethical hacking examples

  • Protection steps and the implementations to prevent injection attacks

At the end of the course you will understand the different type of injection vulnerabilities, perform injection attacks against the vulnerable web applications you have developed, and learn how to protect your applications against the injection attacks using various techniques such as,

  • Validation and sanitisation using white list approach

  • Parametrised queries with prepared statements

  • Escaping output

  • Using secure trusted libraries

  • Error handling and logging

  • General coding practices

If you want to skip the development and only perform the hacking of applications, you can jump into the injection lectures and download the source code provided in the resources section of that lecture. Be aware that you will still need to install PostgreSQL for SQL Injection, MongoDB for NoSQL injection and OpenLDAP docker container for LDAP injection. You can see how to install and configure these data sources in the beginning lectures of each injection section.

Who teaches Web security: Injection Attacks with Java & Spring Boot? Udemy

Udemy thumbnail

Udemy is the largest open marketplace for online courses on the internet. Founded in 2010 by Eren Bali, Oktay Caglar, and Gagan Biyani and headquartered in San Francisco, the company went public on the Nasdaq in 2021 under the ticker UDMY. The platform hosts well over two hundred thousand courses across software development, IT and cloud, data science, design, business, marketing, and creative skills, taught by tens of thousands of independent instructors. Roughly seventy million learners use it worldwide, and the corporate arm — Udemy Business — supplies a curated subset of that catalog to enterprise customers.

Because Udemy is a marketplace rather than a single editorial publisher, the catalog is uneven by design. The strongest material lives in the long-form, project-based courses authored by working engineers — full-stack JavaScript, React, Node.js, Python data science, AWS, Docker and Kubernetes, mobile development with Flutter and React Native, and cloud certification preparation. The CourseFlix listing under this source is the slice of that catalog that has been mirrored here for offline-friendly viewing, organized by topic and updated as new releases land. Pricing on Udemy itself swings dramatically with the site's near-permanent sales, which is why the platform is best treated as a deep reference catalog: pick instructors with strong reviews and a track record of updating their material rather than buying on the headline price alone.

Frequently asked questions

What are the prerequisites for enrolling in this course?
Prospective students should have a basic understanding of Java programming and familiarity with web development concepts. Knowledge of the Spring Boot framework will be beneficial, as the course includes lessons on integrating Spring Boot with security features. A general awareness of web application structures, such as the use of APIs and authentication mechanisms, will also help in grasping the security concepts taught in this course.
What projects will I build during the course?
Throughout the course, students will build several applications focused on demonstrating and securing against various types of injection attacks. This includes creating a SQL Injection application, a NoSQL injection module using MongoDB, and an LDAP injection setup. Students will learn to hack these applications and then implement preventative measures such as validation, sanitization, and the use of prepared statements.
Who is the target audience for this course?
The course is designed for Java web developers who are interested in enhancing their understanding of web security, particularly with respect to injection attacks. It is also suitable for those looking to learn about ethical hacking and application security to better protect their applications against common vulnerabilities listed in the OWASP Top 10.
How does the depth of this course compare to similar offerings?
This course delves deeply into the topic of injection attacks, covering various forms such as SQL, NoSQL, LDAP, and LOG injections. It provides hands-on experience with hacking and securing applications, making it more in-depth than general web security courses. Each type of injection is explored through coding exercises, configuration tasks, and security implementations specific to Java and Spring Boot.
What specific tools or platforms are covered in this course?
The course covers several tools and technologies including Spring Boot, Burp Suite for HTTP Get vulnerabilities, PostgreSQL for SQL injections, MongoDB for NoSQL injections, and Logback for LOG injections. Students will also use Maven for dependency management and learn to implement Spring Data JPA for database interactions.
What topics are not covered in this course?
While the course provides comprehensive coverage of injection attacks, it does not cover other types of web security vulnerabilities outside the OWASP Top 10 injection category. For example, topics like Cross-Site Scripting (XSS), Cross-Site Request Forgery (CSRF), and security misconfigurations are not addressed in this course.
What is the time commitment required to complete the course?
The course consists of 76 lessons, each designed to provide a detailed understanding of injection attacks and their prevention. Although the exact runtime is unspecified, students should allocate sufficient time to engage with the lessons, complete hands-on exercises, and absorb the extensive material on securing web applications using Java and Spring Boot.
