The menace of attackers over the network is unstoppable for the past two decades. The security practitioners and researchers are devising mechanisms to safeguard the network and its components, but still attackers emerge with cutting edge technologies to disturb the intention of legitimate users in the network. Thus, before devising proper defensive mechanisms against a specific attack, it is essential to understand the motive and strategies of the attackers with the proper clarity. This paper presents a virtual honeynet framework to record all the attackers’ activities and analyzes the strategies, tools, and mechanisms followed by the attacker, in a real-time manner. We analyzed the recorded attacks in our framework with respect to different parameters like protocol, ports, honeypots, and IDPS tools to understand the motive behind the attacks. This novel virtual honeynet architecture will give insight to the readers and security practitioners to understand the strategies followed by the attackers as well as the way of designing different traps to secretly follow the attackers in the road toward foolproof safeguarding mechanisms. © Springer Nature Singapore Pte Ltd 2020.

A Detailed Analysis of Intruders’ Activities in the Network Through the Real-Time Virtual Honeynet Experimentation

This paper proposes a novel topology of multimode matrix AC-DC converter which gives multiple DC outputs using a single AC input. The generated multiple outputs appearing across load has both polarity (Positive and negative DC voltages). The control scheme developed for this converter is consisting of Op_Amps and AND gates and IGBTs are used as power devices. The multiple dc output are synthesized using sinusoidal pulse width modulation technique. A prototype model of proposed converter has been implemented and resultant voltage and current waveforms are analyzed. It has been observed that experimental and simulation results are promising for industrial applications with variable voltage.

Intrusion is the primary step to conduct various kinds of network attacks. Most of the intrusion detection and intrusion prevention systems (IDPS) that make use of signature can detect only known attacks, but cannot save resources from new form of attacks like internet worms. Thus, it is necessary to collect information about unknown intrusion dynamically. Honeypots are useful security mechanism that deliberately lure intruders to probe, attack or compromise the systems. This paper presents an agent based honeymesh for protecting the network resources like servers from intrusion related attacks. In our strategy, agent programs make use of decoyports to lure intruders and redirects to honeymesh to understand attackers’ activities. Also, the agents remove malicious processes and executable files on compromised server as soon as honeypots alerts those intrusions. This novel defense mechanism detects and removes new kinds of internet worms without using signatures. © 2016, Springer Science+Business Media New York.

A Decoy Framework to Protect Server from Wireless Network Worms

The formidable threat to internet world is distributed denial of service (DDoS) attacks. In this paper, we present the evolutionary scenario of attacks back from the history to till date. This paper highlights the state-of-the art technology perpetrated by the attackers so far and what are the defense strategies we possess currently in order to counter such attacks. Also, we emphasize the open issues, research, challenges in the context of defense mechanisms against the attacks. The significant purpose of this paper is to create awareness about DDoS attacks in this cyber era for naive users of internet as well as for the security practitioners to comprehendthe updates about DDoS attacks. © Research India Publications.
