About this certification
The Certified Application Security Engineer (CASE) credential, developed in partnership with global application and software development experts, tests the critical security skills and knowledge required throughout a typical software development life cycle (SDLC). The program emphasizes the implementation of secure methodologies and practices in today's insecure operating environment, preparing software professionals with the capabilities expected by employers and academia worldwide.
Unlike traditional application security trainings that focus solely on secure coding guidelines, CASE.NET covers secure requirement gathering, robust application design, and handling security issues in post-development phases. The curriculum includes input validation, defensive coding practices, authentication and authorization, cryptographic attacks, error handling, and session management techniques, all reinforced with an exhaustive range of hands-on labs. The credential maps to the 'Securely Provision' category in the NICE Framework and is available for both .NET and Java platforms.
Who it’s for
The CASE.NET certification is designed for .NET developers with a minimum of two years of experience, as well as individuals who want to become application security engineers, analysts, or testers. It is also suited for professionals involved in developing, testing, managing, or protecting a wide range of applications. Whether you are a developer looking to expand your security expertise or a security professional aiming to specialize in application security, CASE.NET provides the comprehensive skills needed to build secure applications throughout the SDLC.
Recommended experience
A minimum of two years of experience in the InfoSec or software domain is recommended, along with familiarity with the .NET framework and application development concepts. Experience with .NET application development; Understanding of basic security concepts and vulnerabilities; Familiarity with the software development lifecycle; Knowledge of secure coding practices is beneficial but not mandatory

Questions people ask
How does CASE.NET relate to the Java version of the certification?
CASE is available in two variants: CASE.NET and CASE Java. Both cover the same core application security concepts but are tailored to the respective development platform. You can choose the variant that aligns with your technical background.
Is there a lower-level EC-Council certification required before taking CASENET?
No. EC-Council does not require a lower-level certification as a prerequisite for CASENET. However, you must meet one of the eligibility criteria, such as attending official training or having two years of InfoSec/software experience.
Can I take the CASENET exam without attending official EC-Council training?
Yes, you can take the exam without attending official training if you meet one of the alternative eligibility criteria: being an ECSP member in good standing, having two years of relevant work experience, or holding an industry equivalent certification like GSSP .NET/Java. A USD 100 application fee applies in these cases.
What is the retake policy for the CASENET exam?
EC-Council's retake policy is not detailed on the official exam page. For specific retake guidelines, candidates should refer to the EC-Council certification policies and FAQs on their official certification website.
Are there any hands-on labs or practical components in the CASENET exam?
The CASENET exam is a multiple-choice question exam. However, the training program includes an exhaustive range of labs to ensure real-world practice, and the certification validates practical skills through the exam's focus on real-world scenarios.
What job roles does the CASE.NET certification map to?
The CASE.NET certification is designed for .NET developers, application security engineers, analysts, testers, and professionals involved in developing, testing, managing, or protecting applications. It maps to the 'Securely Provision' category in the NICE Framework.
Can I recertify by passing a different EC-Council exam?
EC-Council certifications require renewal through continuing education credits. Passing a higher-level or different EC-Council exam may contribute to your continuing education requirements, but specific recertification policies are detailed on the EC-Council certification website.
Is the CASENET exam available in languages other than English?
The official exam page lists the exam in English. For availability in other languages, candidates should check with EC-Council or their authorized training partners.

These are not trivia. Each one is written against a concept in the book, so when you get one wrong there is somewhere to go and find out why.

Answer it with the picture beside you
This is the part that teaches. The illustration and the written explanation stay where they are while you work, so a scenario stops being a memory test and becomes something you can simply look at.
It teaches · it does not count
A smartphone uses AI to unlock when the owner looks at the camera. Which AI capability is being used?
AImage classification
BFacial recognition
COptical character recognition
DObject detection
Look at the five steps. Detect finds a face, align straightens it, encode turns it into numbers, search compares it with a stored face, and decide answers one question: is this the same person? Classification would only say “a face”. Detection would only draw a box. Neither decides whose.
Then the page shuts, and it starts counting
The same questions come back with the book closed — that run is the one that counts. After it, your coach picks one thing for tonight, sized to the time you have, and brings pages back before you lose them.
