CrowdSourcing Cyber Security programs utilize the knowledge of hackers and security researchers around the world to identify vulnerabilities in systems and applications. There are several types of crowdSourced programs including hacker-powered programs where hackers research vulnerabilities and report them, bug bounty programs where researchers are rewarded for reporting vulnerabilities to programs like HackerOne and BugCrowd, and crowd contests at security conferences. Researchers can participate by learning methodologies, scanning targets, and building proof-of-concepts to report vulnerabilities for cash rewards. CrowdSourcing provides advantages like being more effective by tapping diverse expertise and keeping applications more secure without needing large in-house security teams.
