A tanfolyam célja

Testing plays a very important role in ensuring security and robustness of web applications. Various approaches – from high level auditing through penetration testing to ethical hacking – can be applied to find vulnerabilities of different types. However if you want to go beyond the easy-to-find low-hanging fruits, security testing should be well planned and properly executed. Remember: security testers should ideally find all bugs to protect a system, while for adversaries it is enough to find one exploitable vulnerability to penetrate into it.

Attending this course will prepare software testers to adequately plan and precisely execute security tests, select and use the most appropriate tools and techniques to find even hidden security flaws. Practical exercises will help understanding web application vulnerabilities and mitigation techniques, together with hands-on trials of various testing tools from security scanners, through sniffers, proxy servers, fuzzing tools to static source code analyzers, this course gives the essential practical skills that can be applied on the next day at the workplace.
