Developers and Operations teams (DevOps) have moved towards containers and modern technologies. Attackers are catching up with these technologies and finding security flaws in them. In this workshop, we will look at how we can test for security issues and vulnerabilities in Dockerised environments. Throughout the workshop we will learn how we can find security misconfigurations, insecure defaults and container escape techniques to gain access to host operating system (or) clusters.

Building a Real-World Attack Monitoring Solution by leveraging the ELK Stack

by Himanshu Kumar Das & Prajal Kulkarni


The 2 day training course outlines defense in depth on Network and Application Layer attacks using Elastic stack. During the 2 day training programme, we would conduct hands-on exercise on simulating, correlating, analyzing and mitigating multiple attacks from Layer 4 - Layer 7. We would also cover various case-studies on day-day security requirements on cloud as well as enterprise networks. The course would end with a CTF exercise to participants on visualizing security facts using Elastic stack.

Detailed Course Abstract

With growing trend of Big data, companies tend to rely on high cost SIEM solutions. Continuous Security Monitoring/Alerting of medium and big enterprise is a large challenge in hand today. Logs from thousands of endpoints, servers and perimeter devices is difficult to aggregate, analyze and correlate in real time that can enable better security incident response & event handling. Organization usually end up with massive data breaches due to lack of visibility in their network activities across the infrastructure. Our course would expose you to take control of enterprise wide logs, analyze them in real time using the ELK frameworks. During our course, you would learn to scale the Elastic Stack and generate powerful visualization & data modeling using kibana making analysis of data and decision making simple.

The training will also cover simulating real-world attack scenarios, alerts customisation necessary to respond to a real world attacks/anomalies. With growing cloud based offerings it becomes crucial to understand systems for detecting and responding to attacks. With tools like osquery we will show how a scalable solution for system level anomaly detection can be build.

This training is meant for security enthusiast, DevOps, and startups trying to build an in-house solution. This will be a great learning to set-up one's own an affordable Security Analytics Platform.

Burp Suite for Web and Mobile Security Testing

by Riddhi Shree


If you care about application security, the one tool that you must absolutely be familiar with is an “Interception proxy”. Although there are several interception proxies in existence, depending on the intensity of penetration tests that need to be performed, a penetration tester might choose a simple or an advanced tool with advanced features. Burp Suite is a collection of several simple-yet-powerful tools. It not only works as an 'interception proxy' but also gives users the ability to automate attacks, attack multiple parameters, generate PoCs, statically detect vulnerabilities, perform out of band exploitation, manage sessions across authorization levels, transform data across multiple types, save and export session data between users, and much more! This completely hands-on workshop is meant for web and mobile security testers, penetration testers and security enthusiasts who want to eliminate the grunt work involved in manual analysis of server traffic, and who want to craft customized and effective attacks against web applications to discover high risk security vulnerabilities.

JavaScript for Pentesting the Modern Application Stack

by Bharath Kumar & Subash SN


JavaScript is everywhere! JS is on the client side, JavaScript is on the server side (Node.js), there are way too many JavaScript frameworks both on client and server side. Understanding JavaScript is not optional anymore for Web Security testers. JavaScript is not just one of those things a tester needs to know just so he/she can write XSS payloads. Understanding JavaScript is one of the most fundamental and crucial skills a Web Application security tester can have. Knowledge of Javascript makes you a better security tester and it makes an immense difference in the way someone looks/test applications.

In this workshop, we will start with absolute basics of JavaScript and how JavaScript fits into the web ecosystem. We'll take a deep dive and look at all the essential JavaScript concepts that a security tester must know. We'll look at JavaScript both from client side and server side. You'll gain hands-on practice with real-world vulnerabilities in JavaScript based applications/frameworks. We'll wrap up the training with a Capture The Flag on an application that resembles a real life application.

Learning outcomes

  1. You'll learn the essentials of JavaScript both on client side and server side
  2. You'll understand the importance of JavaScript in the web ecosystem and importance in web security
  3. You'll gain hands-on experience with multiple attacks both on client side and server side
  4. You'll have hands-on practice on how to test for vulnerabilities in JavaScript based applications and also utilizing JavaScript to exploit other vulnerabilities for maximum impact (like script injection attacks)
