Network Hardening Assignment 8 The Internet is vulnerable to myriads kinds of attacks, due to: 1. Vulnerabilities in the TCP-IP protocol 2. No global flow control mechanisms The above two problems lead to many TCP exploits and the dreaded DDoS attacks. We have devised a method of incrementally upgrading the network infrastructure at the transport level that solves the above problems and makes the network significantly more resilient to attacks, particularly the DDoS attack. The approach uses
