In the Internet Era, millions of computer systems are connected to the Internet and the number is increasing infinitely. Maintaining proper Control and configuration for all such networked systems has proved to be impossible. This loophole makes the Internet systems vulnerable to various type of attacks. The objective of this research is to systematically identify a wide list of attacks in transport, session and application layers (Host layers). 148 effective controls are identified for the security attacks in addition to the 113 standard controls. The identified controls are analyzed in order to map and categorize them to the corresponding security layers wise.
