The below agenda represents a collection of topics and classes we deliver on a course, normally or optionally, in depth or in a short version depending on the needs of the client and the actual audience. The below agenda does not represent a lineup of the topics and classes.
For many of the topics in the below agenda we prepare demos, code fixing exercises, and DIY practices. Most of the hands-ons and other practical exercises are available as cloud instances developed and hosted by defdev.eu.
A defdev course for developers consists of the following ingredients:
By default the duration of a course is 2 days, 12 hours education time in the standard case. But it also can take 3 days depending on the demands, the preferences regarding the coverage or the depth and also the options requested. The general content variants are:
Playing with identifying real threats and security requirements
Intro to secure coding
OWASP ASVS topics, an introduction to the areas to protect
How a properly designed infrastructure architecture should be built
Intro to practical secure development
Setting up the right security requirements
Create and train security champions
S-SDLC basics, secure development as integral part of SDLC
Automatic tools and their values, non-automatic tools, pentests, peer code review, assisted code-review
B. Code security
Common server-side vulnerabilities and their defense
Injections: SQLi, XML injections, JSON, XPath, XSS, cookie injection, open redirection, http header injection
Path traversal, XXE, Buffer overflow, Zip bomb, Million laugh, RFI, Insecure file upload, Code execution
Insecure direct object reference
Common client-side vulnerabilities and their defense
XSS (types, impact, causes, defenses, other html injections, BeEF)
CSRF, Clickjacking, Same-origin policy, CORS
Tabnabbing
Server-side defense
Input validation vs encoding
Some security features
Security logging, exception handling
C. Security design
Security by design
Threat modelling
Separation of duties, trust boundaries, security boundaries, defence in depth, principle of least privilege, minimising the attack surface, risk driven mitigation
Practicing is part of many of the above blocks. We start off basic hacking challenges, but the real exercises are about fixing vulnerable codes, and tasks when attendees need to assess code and an application on their own. We mostly offer cloud based facilities to run the exercise environments, so no local installation is needed.
Hands-ons with vulnerable apps
For most of the courses there are intentionally vulnerable applications which we use to demonstrate and learn specific vulnerabilities and how to fix them.
In some cases we use public "damn vulnerable" applications, in some cases we prepared our own applications to practice with.
DIY sonarqube code checking
We assume that developers should be capable of running basic automated tests against the security of their codes on their own. And also be able to tune the SCA tools to produce reasonable false positive and valuable findings ratio.
Normally we teach how to use security plugins of Sonarqube.
We provide sample codes to test. Though the best experience is achieved when developers run the security SCA against their own codes.
See also the extra, on-demand block of 'Assisted code-review lab' below for practicing on your own codes.
DIY ASVS self-audit
OWASP ASVS is the current standard for assessing the security quality and design flaws of a (web) application, and it's the developers who know the answers to the ASVS audit questions. So we take developers to a short journey in assessing the security properties of their applications.
Extras [optional]
Upon request we also deliver additional blocks:
K: In case of languages and frameworks our trainers are familiar with as auditors we can deliver an additional day to let developers apply the knowledge and skills learnt against their own codes. We call it the 'Assisted code-review lab'.
L-N: We also suggest one of the related add-on courses: S-SDLC playbook Hacking applications Security test automation in CI/CD pipelines
Trainers
In delivering the course one or two of the following trainers are involved as lead trainer or co-trainer:
When it comes to the actual proposal we define who is supposed to do the delivery and in what formation or schedule.
This document describes a subject under discussion. The agenda of the training and the particulars of the planned delivery may change during further iterations of the discussion.
