There are a series of vulnerable web applications that you can use to practice your skills in a safe environment. You can get more information about them in the [vulnerable_servers directory in this repository](https://github.com/The-Art-of-Hacking/art-of-hacking/tree/master/vulnerable_servers).
## A Few Popular Tools
The following are a few popular tools that you learned in the video courses part of these series:
[WebSploit](https://websploit.h4cker.org/) is a virtual machine (VM) created by [Omar Santos](https://omarsantos.io) for different Cybersecurity Ethical Hacking (Web Penetration Testing) training sessions delivered at [DEFCON](https://www.wallofsheep.com/blogs/news/packet-hacking-village-workshops-at-def-con-26-finalized), [Live Training in Safari](https://www.safaribooksonline.com/search/?query=omar%20santos&extended_publisher_data=true&highlight=true&is_academic_institution_account=false&source=user&include_assessments=false&include_case_studies=true&include_courses=true&include_orioles=true&include_playlists=true&formats=live%20online%20training&sort=relevance), [video on demand LiveLessons](https://www.safaribooksonline.com/search/?query=omar%20santos&extended_publisher_data=true&highlight=true&is_academic_institution_account=false&source=user&include_assessments=false&include_case_studies=true&include_courses=true&include_orioles=true&include_playlists=true&formats=video&sort=relevance), and others.
You can integrate ZAP with Jenkins and even automatically create Jira issues based on your findings. You can download the [ZAP plug in here](https://wiki.jenkins.io/display/JENKINS/zap+plugin).
