DARKHADOOP RISHABH SHARMA CDAC-ACTS Email: [email protected] ABSTRACT With the emergence of network globalization and advent of Internet being the major tool for international information exchange and platform for the future. Security has always been the most talked about topics. Network administrators have often tried their best by improving their network security, however with rapid surface of new expolits, the best way of ensuring that the system is secure is to take the entire system to a new level of complexity.To protect the critical data we need to store it in a complex infrastructure named Dark Net.To process our big chuck of log a efficient distributed approach is required which is being fullfilld by Hadoop. INTRODUCTION When system & network admin talk about plugging all the holes and securing there network of denial-of-service attacks, one of the least talk about but one of the most effective network security technique is sinkholing. A sinkhole is defined as a method in which we redirect specific IP network traffic for different security reason for analysis,diversion of attacks and detection of anamolus activities. However for the network administrators, sinkholes are generally deployed to provide valuable intelligence regarding the security threats there networks are facing. Two kinds of sinkholes implementations: 1. DARKNETS 2. HONEYNETS Ok what is a sinkhole again..?? Say a malicious hacker has a target of 192.168.2.113, as shown in the figure above. The target is part of a network block 192.168.2.0/254. When the hacker unleashes his DDOS attack, he is not only disrupting the business operations of the target organization, but also crippling the network besides increasing their cost$ because of the increasing bandwidth utilization. If the organization complains to the ISP, what they would then do is initiate a blackhole type sinkhole, by injecting a specific route for the target. They make the next hop the discard interface on their edge router. This is also known as null() or the “bit bucket”. What this effectively did was redirect the offensive traffic towards the ISP’s sinkhole instead of allowing it to flow downstream to the original target. Unfortunately, the downside is that the IP being attacked cannot communicate with the internet until the sinkhole is removed. A workaround could be that the target gets a different IP, but then you have to think about stuff like DNS TTL expiry and so on…. WHAT IS DARKNET : A Darknet is a private file sharing network where users only connect to people they trust. Typically such networks are small, often with fewer than 10 users each. It is a portion of routed, allocated IP space in which no responsive services reside. So again, why the name Darknet because there is nothing “lit up” inside these networks. So how are they used in the so called entrapment? Well, no legitimate packets should ever enter a darknet. So if one does appear, it is either because of misconfiguration or malware scanning for vulnerable devices. Thus, because of this a darknet is a powerful security tool because a security administrator can spot scanning without the need for complicated analysis gear and best of all, without any false positives. At the same time, a darknet could be complemented with the inclusion of detectors, packet sniffers and IDS systems. DARKNET CAN BE USED AS A FUTURE IDS (INTRUSION DETECTION SYSTEM) & IPS (INTRUSION PREVENTION SYSTEM). WHAT IS HADOOP : Apache Hadoop is an open-source software framework for storage and large-scale processing of data-sets on clusters of commodity hardware. Hadoop is an Apache-toplevel project being built and used by a global community of contributors and users. It is licensed under the Apache license 2.0. The Apache Hadoop framework is composed of the following modules: Hadoop Common – contains libraries and utilities needed by other Hadoop modules. Hadoop Distributed File System (HDFS) – a distributed file-system that stores data on commodity machines, providing very high aggregate bandwidth across the cluster. Hadoop YARN – a resource-management platform responsible for managing compute resources in clusters and using them for scheduling of users' applications. Hadoop MapReduce – a programming model for large scale data processing. MY PROJECT ON DARKHADOOP: The project is on DARKHADOOP. Which is a combination of DARKNET & HADOOP. We use the DARKNET concept to protect webserver from attackers.we use it as a IDS & IPS. We thinking that this project is useful in future to make such a complex security INFRASTRUCTURE that help to protect the webserver. EXPLAINATION OF DARKHADOOP: In my project we take a scenario that daily thousands of attack done to the google server.so to protect and to collect the attacker information we use darknet. We take three machines.we use one machine as a router and in router we use sniffer script that monitor all the packet travel from the router and in this script it is decide that the attack is done or not.in secound machine we use three virtual machine which is darknet in my project and third machine is for hadoop that use map reduce algorithm and send top ten attacks to the administrator watsapp number. Rough sketch of a project only difference is the google.com server is not at that place where it is shown.it is in other machine. Let say if attacker attack on google webserver.then all traffic goes from router where sniffer script monitor all packets,and in sniffer script the different attacks is defined if any condition true then the IP of attacker block by IP Tables for 1 day and send the IP and attack name to the darknet. Darknet is made by three virtual machines as shown in figure.lets assume that this three machines in diffrent country or locations and between them the IP is circulated in 1 min gap as shown in figure we takw a IP pool of 22,23,24,25 one extra ip. We say that IP & attack name send to darknet.in darknet some data copied to one virtual machine some data to other.there is no particular place no one know where data is saved.and we know last part of hacker to remove footprints.let say attackes find the IP where log stored and let say attacker also connect to that but because of 1 min time they disconnect and if they again scan of that IP it can find that IP in different location.so it is complicated to remove footprints.we can make it more complicated by adding more machines in darknet and port forwarding. Now after data store in darknet it can send to hadoop for the map reducing because the data is in large amount.we use hadoop to find top 10 attack who can attack more and that top ten list is send to administrator we use RASPBEERY PI to send top ten attack to the administrator watsap . CONCLUSION The main objective of the project is to apply the various technologies learnt during the course of instruction. The application has been created to detect various attacks and sending log to hadoop using darknet. It can be used for network protection of an organization, and further development can also be done on this concept. So even though something useful was created in this project, there is still potential to expand what we’ve done to capture more data and automate the task of extracting the data into a user friendly format. There is also a lot of potential to taking another step to fully integrate the data and to somehow automate the process of extracting information about specific events. THIS IS FUTURE SECURITY INFRASTRUCTURE USED TO PREVENT ATTACKS. WE ONLY GET TEN DAYS TO MAKE THIS PROJECT .WE HAVE MORE IDEAS TO MAKE IT MORE COMPLEX AND SECURE. IN MY PROJECT WE ARE FOUR MEMBERS (RISHABH SHARMA , RAUSHAN RAJ , MOHIT VYAD,KRISHAN GOPAL). WE GET A+ IN THIS PROJECT.IN THE CLASS OUR PROJECT IS ON THE TOP LIST.
