Internet is a worldwide network and used in almost every field of work such as industrial, educational, military etc. Based on the use, its security needs differ. Few applications may need less security and few may need high security. Today various internet attacks are being developed every day, such as viruses, DoS (Denial of Service), spoofing, etc. Spoofing is a kind of attack in which attacker masks itself under some other user’s IP address. Thus, it is difficult to find the original attacker. IP traceback technique is used to detect the DoS attack. This paper is based on IP traceback, which will help to detect the spoofing attacker by using packet marking and packet logging technique. In packet marking technique router marks identification information of its own into the forwarded packets. In packet logging, routers keep the digest information regarding the forwarded packets. Proposed scheme is termed as E-RIHT (Enhanced Routers Interface Hybrid Traceback) in this, memory requirement will be less because we are using marking field of 16-bit, which will also solve the packet fragmentation problem. |
