Is your web application easy to hack using common attacks?

  • Do you have any idea how many files you send to the user are modified in transit?
  • When a user logs in, do you know if they are impersonated by an attacker?
  • Are you performing access control checks at the right places, with the right data?
  • Are you fully aware of the devastating effects of XSS, regardless whether it's stored or reflected?

Key Area 1

Keep your business private by securing the communication channel


In the modern web, end users have gone mostly wireless, which is wonderful for usability, but quite worrisome for security. Compared to the wired days, both passive and active network attacks have become easy to execute, and difficult to detect. In essence, without a full HTTPS deployment, the communication channel can no longer be considered private, and can no longer be trusted.


How much sensitive information is up for grabs to an eavesdropper?

Is there an attacker sitting in the middle, with the ability to carry out a dangerous SSL Stripping attack?


Today, simply deploying HTTPS is no longer sufficient. You need to move all of your content to HTTPS, and deploy additional security policies to establish a secure end-to-end communication channel. In this session, you will learn:

  • why a partial HTTPS deployment can easily be undermined by easy-to-execute network attacks
  • how to leverage the latest security technologies, like HSTS, to prevent attacks such as SSL Stripping
  • how to deal with mixed content, the number one issue when switching from HTTP to HTTPS
  • best practices for deploying HTTPS correctly, and verifying your deployment with automated tests

Key Area 2

Confirm your user’s identity with strong authentication


Billions of users have lost an online identity in a data breach, making their account details and personal information publicly available. And while the effects of a data breach of one application can already be devastating, it becomes a true nightmare if an attacker starts re-using stolen credentials to impersonate the user elsewhere.


Are the credentials you store easily retrieved in the event of a breach?

Does your application leak information, thereby exposing you to targeted brute-force attacks?


By protecting the user management flows in your application, you can effectively protect your user's identities, even in case of a potential breach. In this session, you will learn:

  • how your applications can effectively help users to improve their security practices
  • about common attacks against user management flows that occur in most applications
  • how to integrate effective countermeasures that neutralise these common attacks
  • about the benefits of multi-factor authentication, and practical ways to integrate this in your applications

The gained knowledge and skills are directly applicable, and immediately shared with colleagues. This training has changed the way we work and affected the security of our product.

Key Area 3

Avoid authorization bypasses by locking down your sessions


Authorization bypass attacks are so common that they are covered by 4 items in the OWASP top 10. Coincidentally, various built-in session management mechanisms need additional tweaking to be secure. And because of the nature of the web, an attacker can launch such attacks from within the user's browser, thereby targeting internal systems on private networks, such as intranet applications, routers, printers, etc.


Are your session identifiers or session objects vulnerable to common attacks?

Does your backend know if a user intended to perform an action, or is it vulnerable to CSRF?


Avoiding authorization bypasses depends on making access control decisions with trusted data. In a web context, this means that everything coming from the client is considered untrusted, even the existence of the request itself. In this session, you will learn:

  • why almost all built-in session management mechanisms are vulnerable to common attacks, and how to fix them
  • how to add intent to requests coming from the browser, allowing the backend to prevent harm being done by uninentional requests
  • how to correctly move from server-side session management to client-side session management, either with cookies or with tokens
  • why Direct Object References can be insecure, and how to prevent this common vulnerability in your application

Key Area 4

Refuse to be compromised and neutralize code injection attacks


Cross-Site Scripting (XSS) vulnerabilities. Google has them. Facebook has them. Your application has them. XSS vulnerabilities are so severe, that bug bounty programs have turned it into a million dollar business. The main reason that XSS is so dangerous, is because it gives an attacker full control over a user's context, allowing him to access private data, make requests to the backend, ...


Do you correctly encode your untrusted data, or are you vulnerable to XSS attacks?

Do you know how Content Security Policy can help you neutralize XSS attacks?


Tackling injection attacks is a challenging task, regardless whether it's a new or an existing application. Fortunately, by adhereing to a few best practices, you can vastly improve the security of your application. In this session, you will learn:

  • first-hand which tremendous power you get by successfully exploiting an XSS vulnerability
  • why almost every web application is vulnerable to XSS attacks, and the only right way to stop them
  • how modern JavaScript frameworks can actually make the problem a bit easier to solve
  • how to leverage the power of the recent Content Security Policy, and how to overcome common deployment problems

The November 2017 edition of the course is fully booked.

Maarten Segers, Consultant, AMPLEXOR

Web security and application security are gaining mor and more attention. As a developer, you know what's going on, but since these domains are very broad, it is hard to see the full picture. We were not sure whether the Web Security Essentials was a good fit for our company.

Once the course started, these doubts vanished. The course is well-structured, and accessible for both frontend and backend developers. It changes the way you look at the development of web applications. Following theory sessions with hands-on labs creates an interesting combination. On top of that, you get a head start with the right tools to assess your own application. The gained knowledge and skills are directly applicable, and immediately shared with colleagues. This training has changed the way we work and affected the security of our product.

This training deserves a high recommendation. The course offers varied, up-to-date and detailed content. Security may still be low on the radar, but this 2-day training already makes a world of difference.


Sam Verschueren, Lead Software Engineer, Pridiktiv NV

As web architect, security is an important concern in the design and implementation of an application. However, I must admit, my knowledge on the subject was quite sparse as it was difficult to me to find a main reference on the subject.

For this reason I decided to join the Web Security Essentials training. The course allowed me to have a complete overview on the subject, understand the main security pitfalls, and use some of the most important tools to overcome them.

The awareness of the main security threats is key in my daily work with big companies and the course well addresses it via the presentations and the practical labs. I would recommend this training to all web developers and architects: the balance between the slide sessions and the practical labs made the course a joyful full-immersion in the security field.


Nicola Di Giorgio, Software Architect/CEO, PREGIOTEK sprl

Thanks for providing this course packed with very up-to-date information. I greatly appreciated the good balance between theory and hands-on labs which allowed me to gain a deeper understanding and new insights on web security measures to defend against current threats. I'm also really grateful for the excellent hand-outs, providing concise but complete information presented in a way that helped me a lot to better understand the more advanced web security mechanisms.

Stefan Eestermans, ICT Security Consultant, Optaris sprl

I was looking for information to get an idea of what kind of issues modern web applications face (or do not face), and how much an attacker needs to invest to launch various kinds of attacks. I do not believe such information can be obtained from high-level overview presentations. I was looking for a more hands-on approach, to get some experience with issues that managers often sweep under the rug as unimporant.

The course delivered on my expectations, not only by confirming that modern web applications face various threats, but also by clarifying that numerous threats depend on the level of freedom users have. Thanks to the Web Security Essentials course, I know have a better and more concrete understanding of what needs to happen to build a secure application.
