We choose the video streaming application in this task. The learning objective of this lab is for students to gain first-hand experience on vulnerabilities, as well as on attacks against these vulnerabilities. 2 SSH connection3. Server. In security education, we study mistakes that lead to software vulnerabilities. The vulnerabilities in the TCP/IP protocols represent a special genre of vulnerabilities in protocol designs and implementations; they provide an invaluable lesson as to why security should be designed in from the beginning, rather than being added as an afterthought. 0】Public-Key Infrastructure (PKI) Lab # TCP/IP Attack Lab ##### tags: `SUTD` `SEED Labs` `Network Security` `Lab` *Done by: Lin Huiqing SEED Labs – TCP/IP Attack Lab 5 In this task, you need to launch an TCP RST attack to break an existing telnet connection between A and B.
