DETECTION OF APPLICATION LAYER DDOS ATTACKS USING INFORMATION THEORY BASED ME...cscpconf
Distributed Denial-of-Service (DDoS) attacks are a critical threat to the Internet. Recently,
there are an increasing number of DDoS attacks against online services and Web applications.
These attacks are targeting the application level. Detecting application layer DDOS attack is
not an easy task. A more sophisticated mechanism is required to distinguish the malicious flow
from the legitimate ones. This paper proposes a detection scheme based on the information
theory based metrics. The proposed scheme has two phases: Behaviour monitoring and
Detection. In the first phase, the Web user browsing behaviour (HTTP request rate, page
viewing time and sequence of the requested objects) is captured from the system log during nonattack
cases. Based on the observation, Entropy of requests per session and the trust score for
each user is calculated. In the detection phase, the suspicious requests are identified based on
the variation in entropy and a rate limiter is introduced to downgrade services to malicious
users. In addition, a scheduler is included to schedule the session based on the trust score of the
user and the system workload.

Network Security consists of the provisions and policies adopted by a network
administrator to prevent and monitor unauthorized access, misuse, modification,
or denial of a computer network and network-accessible resources. Network
security involves the authorization of access to data in a network, which is
controlled by the network administrator. Users choose or are assigned an ID and
password or other authenticating information that allows them access to
information and programs within their authority.

Survey Paper: Cryptography Is The Science Of Information SecurityCSCJournals
Cryptography in the past was used in keeping military information, diplomatic correspondence secure and in protecting the national security. However, the use was limited. Nowadays, the range of cryptography applications have been expanded a lot in the modern area after the development of communication means; cryptography is essentially required to ensure that data are protected against penetrations and to prevent espionage. Also, cryptography is a powerful mean in securing e-commerce. Cryptography is used to ensure that the contents of a message are confidentiality transmitted and would not be altered. Confidentiality means nobody can understand the received message except the one who has the decipher key, and data cannot be changed means the original information would not be changed or modified; this is done when the sender includes a cryptographic operation called a hash function in the original message. A hash function is a mathematical representation of the information, when any information arrives at its receiver; the receiver calculates the value of this hash function. If the receiver’s hash function value is equivalent to the sender’s, the integrity of the message is assured .

Defense mechanism for ddos attack through machine learningeSAT Journals
Abstract
There is a huge advancement in Computer networking in the past decade. But with the advancement, the threats to the computer networks are also increased. Today one of the biggest threats to the computer networks is the Distributed Denial of Service (DDoS) flooding attack. This paper emphasizes the application layer DDoS flooding attacks because these (layer seven) attacks are growing rapidly and becoming more severe problem. Many researchers used machine-learning techniques for intrusion detection, but some shows poor detection and some methods take more training time. From a survey, it is found that Naïve Bayes (NB) algorithm provides faster learning/training speed than other machine learning algorithms. Also it has more accuracy in classification and detection of attack. So we are proposing a network intrusion detection system (IDS) which uses a machine learning approach with the help of NB algorithm.

Study of flooding based ddos attacks and their effect using deter testbedeSAT Journals
Abstract Today, Internet is the primary medium for communication which is used by number of users across the Network. At the same time, its commercial nature is causing increase vulnerability to enhance cyber crimes and there has been an enormous increase in the number of DDOS (distributed denial of service attack) attacks on the internet over the past decade. Whose impact can be proportionally severe. With little or no advance warning, a DDoS attack can easily exhaust the computing and communication resources of its victim within a short period of time. Network resources such as network bandwidth, web servers and network switches are mostly the victims of DDoS attacks. In this paper different types of DDoS attacks has been studied, a dumb-bell topology have been created and effect of UDP flooding attacks has been analyzed on web service by using attack tools available in DETER testbed. Throughput of web server is analyzed with and without DDoS attacks.
XDOSER, A BENCHMARKING TOOL FOR SYSTEM LOAD MEASUREMENT USING DENIAL OF SERVI...IJNSA Journal
Technology has developed so fast that we feel both safe as well as unsafe in both ways. Systems used today are always prone to attack by malicious users. In most cases, services are hindered because these systems cannot handle the amount of over loads the attacker provides. So, proper service load measurement is necessary. The tool that is being described in this paper for developments is based on the Denial of Service methodologies. This tool, XDoser will put a synthetic load on the servers for testing purpose. The HTTP Flood method is used which includes an HTTP POST method as it forces the website to gather the maximum resources possible in response to every single request. The tool developed in this paper will focus on overloading the backend with multiple requests. So, the tool can be implemented for servers new or old for synthetic test endurance testing.

Optimised malware detection in digital forensicsIJNSA Journal
On the Internet, malware is one of the most serious threats to system security. Most complex issues and
problems on any systems are caused by malware and spam. Networks and systems can be accessed and
compromised by malware known as botnets, which compromise other systems through a coordinated
attack. Such malware uses anti-forensic techniques to avoid detection and investigation. To prevent systems
from the malicious activity of this malware, a new framework is required that aims to develop an optimised
technique for malware detection. Hence, this paper demonstrates new approaches to perform malware
analysis in forensic investigations and discusses how such a framework may be developed.
Network Threat Characterization in Multiple Intrusion Perspectives using Data...IJNSA Journal
For effective security incidence response on the network, a reputable approach must be in place at both protected and unprotected region of the network. This is because compromise in the demilitarized zone could be precursor to threat inside the network. The improved complexity of attacks in present times and vulnerability of system are motivations for this work. Past and present approaches to intrusion detection and prevention have neglected victim and attacker properties despite the fact that for intrusion to occur, an overt act by an attacker and a manifestation, observable by the intended victim, which results from that act are required. Therefore, this paper presents a threat characterization model for attacks from the victim and the attacker perspective of intrusion using data mining technique. The data mining technique combines Frequent Temporal Sequence Association Mining and Fuzzy Logic. Apriori Association Mining algorithm was used to mine temporal rule patterns from alert sequences while Fuzzy Control System was used to rate exploits. The results of the experiment show that accurate threat characterization in multiple intrusion perspectives could be actualized using Fuzzy Association Mining. Also, the results proved that sequence of exploits could be used to rate threat and are motivated by victim properties and attacker objectives.
NETWORK INTRUSION DETECTION AND COUNTERMEASURE SELECTION IN VIRTUAL NETWORK (...ijsptm
Intrusion in a network or a system is a problem today as the trend of successful network attacks continue to
rise. Intruders can explore vulnerabilities of a network system to gain access in order to deploy some virus
or malware such as Denial of Service (DOS) attack. In this work, a frequency-based Intrusion Detection
System (IDS) is proposed to detect DOS attack. The frequency data is extracted from the time-series data
created by the traffic flow using Discrete Fourier Transform (DFT). An algorithm is developed for
anomaly-based intrusion detection with fewer false alarms which further detect known and unknown attack
signature in a network. The frequency of the traffic data of the virus or malware would be inconsistent with
the frequency of the legitimate traffic data. A Centralized Traffic Analyzer Intrusion Detection System
called CTA-IDS is introduced to further detect inside attackers in a network. The strategy is effective in
detecting abnormal content in the traffic data during information passing from one node to another and
also detects known attack signature and unknown attack. This approach is tested by running the artificial
network intrusion data in simulated networks using the Network Simulator2 (NS2) software.

DDOS Detection
1. RESEARCH ON: DDos Attack Detection Using Entropy Method
Abstract:
The main achievement of our project would be to detect the DDoS attack; this will help to
differentiate between legitimate users and malicious users. On other hand our project provides a
trace back mechanism through which one can know from where the attacks are coming, through
which zombie computers. This document will define the design of the detection of DDoS attack
using Fast Entropy Method.
Among the various security threats that have evolved till now, Denial of Service attack is the
most destructive according to security experts. A Denial of service attack is basically used to
block any service for intended users. A Distributed Denial of Service attack generates substantial
packets by a large number of agents and can easily tire out the processing and communication
resources of a victim within very less period of time. Defending DDoS problem involved several
steps from detection, characterization and trace back in order to do mitigation.
The main purpose of this research paper is the detection of Distributed Denial of service attacks
using fast entropy method and different tools will be used to detect DDos attack for given data
set. The objective broken down into smaller categories to make our research effective and
reactive.
• Our first objective understands the subject in detail by going through previous papers and
methods used to detect DDos attack.
• Second objective is to choose the latest method used for DDos detection and start
working on it.
• Third objective is to choose tools that are requires to carry out implementation. Since
carrying out attack needs extra care when compared to simulation.
This project also demands proper ways to measure the attack when it is actually occurring.
Summing up the objective of our research would be to investigate and learn subject in depth,
implementing the DDos attacks, use method that detect that attack.
