Hi, I am Vignesh.K pursuing Final Year BE.Computer Science Engineering in Mailam Engineering college at Villupuram, today date is 17 Aug 2019, it's a rainy morning , it's a day I am started writing blog. I want say about my knowledge, I am an average student in studies but I want to learn things practically that's why go with self learning, I am interested in the Topics, Computer Networks, Penetration Testing, Linux, Operating System . I have practiced some of the things under penetration testing like nmap, metasploit, Burpsuit, shodan. nmap is tool, used scan the vulnerability of the website and extract some information about the website like what are the protocols are active and open the server operating system and so on, the tool is open source we can download in the github, nmap . metasploit is a hacking frame work, we can use metasploit to hack most of the device, I am a beginner in the metasploit, I have practiced some things in the metasploit they are ha
