Finally, he provides an overview of Humanitec's platform, which provides open-source tools you can use when you're building your own IDP.

No system is free of security vulnerabilities, which can be exploited to gain access to restricted resources. Ethical hackers are our allies, using the same techniques as malicious actors to help us find and fix the security vulnerabilities of our systems. In this short introductory article, we explore: the different types of hackers, the goals of ethical hacking and the main activities of ethical hackers.
