We propose LIPS as an domain-to-domain approach to stop unwanted attacks, without requiring broad changes in backbone networks as other approaches. Therefore, LIPS is incrementally deployable in a large

In this paper, we propose a lightweight, scalable packet authentication mechanism, named Lightweight Internet Permit System (LIPS), as a first line of defense to stop unwanted traffic. LIPS is a

Traffic classification and distinction allows network operators to provision resources, enforce trust, control unwanted traffic, and traceback unwanted traffic to its source. Today’s classification mechanisms rely primarily on IP addresses and port numbers; unfortunately, these fields are often too

Abstract. In this paper we present PeerRush, a novel system for the identification of unwanted P2P traffic. Unlike most previous work, Peer-Rush goes beyond P2P traffic detection, and can accurately categorize the detected P2P traffic and attribute it to specific P2P applications, including

Abstract—In this paper, we investigate temporal and spatial correlations of time series of unwanted traffic (i.e., darknet or network telescope traffic) in order to estimate statistical behavior of unwanted activities from a small size of darknet address block. First, from the analysis of long

Abstract- This paper present how the security can be given to the wireless network with the help of intrusion detection system and firewalls. With the rapid growth of application of Internet in various walks of life, the study of Security has become inevitable. Wireless networks are providing tremendous benefit for a number of industries. This paper focuses different kinds of wireless network i.e. mobile ad hoc network, wi-fi and bluetooth. Although Wireless Networks have appealing features (e.g., low installation cost, unattended network operation), due to the lack of a physical line of defense (i.e., there are no gateways or switches to monitor the information flow), the security of such networks is a big concern.
