An approach to enhance low -interaction honeypots by enabling them to detect spoofing attacks via network analysis
No full textA spoofing attack is when a malicious party imitates another system on a network as being from a known, trusted source and initiates attacks on network administrators to steal data, bypass network access or perform DDoS attacks. Spoofing attacks are a rising problem for companies both big and small costing them billions of dollars for the same. Honeypots are often used in organisations to both bait the attackers and to detect underway attacks. Low-interaction honeypots that imitate basic network services, internet protocols and operating systems are more likely to be used because of their cost-effectiveness but since they are limited in their abilities, organizations prefer high-interaction honeypots which are both expensive and resource heavy. Therefore, it was necessary to propose a method of detection of spoofing attacks with minimal resources to meet the needs of all. This paper proposes a spoofing attack detection mechanism for IP, ARP and DNS spoofing by enhancing the functionalities of a low interaction honeypot by incorporating some additional intelligence to make them detect basic spoofing attacks and capture all the network traffic. Tshark is used to capture the network traffic and then different scripts are implemented on them to categorize the network packets as spoofed or genuine. Next, these results are compared to the logs from the honeypots to see how our enhancement scripts have worked compared to them
COZMO - A new lightweight stream cipher
No full textThis paper deals with the merger of the two lightweight stream ciphers – A5/1 and Trivium. The idea is to make the key stream generation more secure and to remove the attacks of the individual algorithms. The bits generated by the Trivium cipher (output) will act as the input of the A5/1 cipher. The registers used in the A5/1 cipher will be filled by the output bits of the Trivium cipher. The three registers will then be connected to generate an output which will be our required key stream. we are using Trivium and A5/1 algorithm and making changes to suit our needs.</jats:p
