 good morning to you. So, before I start the introduction and with my presentation let discuss something about the recent facts and the recent attacks. So, as you guys know that thousands of attacks has been made every year on web applications or any website like GitHub, the largest online repository which we use to make our project centralized. So, last year GitHub was attacked by DDOS, Daniel Agnial Observice Attack. So, you can imagine that how can it make impact on any company's business. And another take another example of eBay. eBay was a victim of cross-site scripting where what attackers did they injected their script to the home page of eBay. So, when you launch the URL of eBay it will show you a fake or the false login page and if you enter your credentials there it will take you the false home page or your credentials will directly go to the attackers. So, they have all the access of your account. Facebook. Facebook organizes bug bounty program every year where they elect penetration tester or ethical hacker to find any vulnerability in their application. So, last year in such a bug bounty program and penetration tester named Orange T. Psi has discovered a backdoor in Facebook server and the most interesting thing is that that backdoor has already faced by another attacker. So, in the last year and with the code which can exploit the critical information of Facebook staff. So, this kind of attacks can make a big impact of any website any website's business. So, as I am Sarvesh Shivastho I am from Q and for Tech Noida. I have been working in testing domain especially in automation testing from last two years. So, you all must have a brief idea about the security testing, what are the security concerns and how we to perform security testing manually.
