OWASP 2017 - This .NET secure coding training course is led by an expert Application Security specialist and delivers focused and customised guidance on how to secure Applications (from code to cloud), covering the technology stack currently used by the delegates (web, mobile, cloud, ASP.NET, MVC, etc...).

A highly popular course with plenty of discussion, demos and interactive Labs to demonstrate the issues faced by modern software development teams.

An optional threat modelling session can also precede the course delivery.

Web Developers (ASP.NET) who need to learn about secure coding best practice and implement the guidelines on Payment Card Industry (PCI) Compliance


4.8 out of 5 average

"Really helpful course understanding PCI compliance standards and a good detailed refresher on general security principles. Presented with a huge amount of resources on how to structure security in an organisation right through to identifying and handling it."

How this course is run

This interactive, lab-focused, workshop-style course will provide delegates with a sound understanding on how to build secure ASP.NET applications. Delegates should come in with an open mind to structure, as many of the topics below will be exposed and discussed in the context of sites and applications being analysed, rather than in the strict sequence below.

Security Principles and SD3 (Secure by Design, Default, Deployment)

The course is designed to cover at least the OWASP top 10 and the Secure Application Development part of PCI DSS (Payment Card Industry Data Security Standard). Usually (based on delegate’s current focus) a number of other areas are covered, like for example: Unit/Integration Testing, Static Analysis tools, Penetration Testing, Code Reviews, Secure coding in Agile environments, Self-Defending applications, ASP.NET MVC (Core 1)  Security, Security as a key component of Continuous Deployment/Delivery.

Techniques to exploit vulnerabilities

This workshop will provide delegates with a solid understanding of the security implications of writing insecure code on applications exposed to malicious traffic (websites, web services, REST APIs, rich clients and Javascript driven web apps).

Secure coding practices

The key objective of the course is to make a ‘paradigm shift’ on the delegates, where they learn what are the security properties the applications they are coding should contain. Some aspects covered are generic to all web developers – while others are Java and Javascript specific, but since vast majority of flaws within applications are due to flawed design, implementation, or programmer errors, the most important outcome is to learn what questions to ask.

Testing an application for security

Common tools and techniques for Developers to use in their day-to-day Agile environment to help test that their applications are robust and capable of withstanding common threats


What matters for PCI DSS compliance and Privacy considerations


Although secure coding is a large part of the course, there will be the opportunity to learn and write exploits around multiple OWASP Top 10 vulnerabilities (like XSS, CSRF, SQL Injection or Indirect Object Reference).


The workshop will simulate a real-world Threat Modeling session, with (ideally) the target being a application currently maintained by some (or all) of the attending delegates.

A very common outcome is that new high-risk vulnerabilities are discovered during the course (the backup plan is to use vulnerable-by-design demo applications, but the learning impact is not the same as when the delegates see real-world vulnerabilities in their applications).


OWASP Top 10 – 2017 (New)

A1 – Injection
A2 – Broken Authentication and Session Management
A3 – Cross-Site Scripting (XSS)
A4 – Broken Access Control (Original category in 2003/2004)
A5 – Security Misconfiguration
A6 – Sensitive Data Exposure
A7 – Insufficient Attack Protection (NEW)
A8 – Cross-Site Request Forgery (CSRF)
A9 – Using Components with Known Vulnerabilities
A10 – Underprotected APIs (NEW)

OWASP Top 10 – 2013

A1 – Injection

Injection flaws, such as SQL, OS, and LDAP injection occur when untrusted data is sent to an interpreter as part of a command or query. The attacker’s hostile data can trick the interpreter into executing unintended commands or accessing data without proper authorization.


A2 – Broken Authentication and Session Management

Application functions related to authentication and session management are often not implemented correctly, allowing attackers to compromise passwords, keys, or session tokens, or to exploit other implementation flaws to assume other users’ identities.

A3 – Cross-Site Scripting (XSS)

XSS flaws occur whenever an application takes untrusted data and sends it to a web browser without proper validation or escaping. XSS allows attackers to execute scripts in the victim’s browser which can hijack user sessions, deface web sites, or redirect the user to malicious sites.

A4 – Insecure Direct Object Reference

A direct object reference occurs when a developer exposes a reference to an internal implementation object, such as a file, directory, or database key. Without an access control check or other protection, attackers can manipulate these references to access unauthorized data.

A5 – Security Misconfiguration

Good security requires having a secure configuration defined and deployed for the application, frameworks, application server, web server, database server, and platform. Secure settings should be defined, implemented, and maintained, as defaults are often insecure. Additionally, software should be kept up to date.

A6 – Sensitive Data Exposure

Many web applications do not properly protect sensitive data, such as credit cards, tax IDs, and authentication credentials. Attackers may steal or modify such weakly protected data to conduct credit card fraud, identity theft, or other crimes. Sensitive data deserves extra protection such as encryption at rest or in transit, as well as special precautions when exchanged with the browser.

A7 – Missing Function Level Access Control

Most web applications verify function level access rights before making that functionality visible in the UI. However, applications need to perform the same access control checks on the server when each function is accessed. If requests are not verified, attackers will be able to forge requests in order to access functionality without proper authorization.

A8 - Cross-Site Request Forgery (CSRF)

A CSRF attack forces a logged-on victim’s browser to send a forged HTTP request, including the victim’s session cookie and any other automatically included authentication information, to a vulnerable web application. This allows the attacker to force the victim’s browser to generate requests the vulnerable application thinks are legitimate requests from the victim.

A9 - Using Components with Known Vulnerabilities

Components, such as libraries, frameworks, and other software modules, almost always run with full privileges. If a vulnerable component is exploited, such an attack can facilitate serious data loss or server takeover. Applications using components with known vulnerabilities may undermine application defenses and enable a range of possible attacks and impacts.

A10 – Unvalidated Redirects and Forwards

Web applications frequently redirect and forward users to other pages and websites, and use untrusted data to determine the destination pages. Without proper validation, attackers can redirect victims to phishing or malware sites, or use forwards to access unauthorized pages.
