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.
Keywords: DDoS (Distributed Denial of Service) flooding attack, Machine Learning, Naïve Bayes, Network Intrusion Detection
This document discusses packet sniffing and methods for detecting packet sniffers. It defines packet sniffing as monitoring all network packets and describes common packet sniffer tools like tcpdump. It explains that packet sniffers can be used for both legitimate and malicious purposes, such as password theft or network mapping. The document outlines two key methods for detecting packet sniffers - MAC detection and DNS detection. MAC detection works by sending packets with invalid MAC addresses and checking if any hosts respond in promiscuous mode. DNS detection exploits the behavior of sniffers performing DNS lookups on spoofed source IP addresses. Both methods were found to accurately detect the presence of packet sniffers on a network.
The document discusses cloud security from the perspective of Wen-Pai Lu, a technical leader at Cisco.

Caldera is an automated adversary emulation tool developed by MITRE that links to the MITRE ATT&CK framework. It deploys custom backdoors on target systems to emulate adversary techniques. The tool has a graphical interface to define groups, abilities, adversaries, and operations. Abilities are suites of actions that achieve goals, while adversaries are malicious actors equipped with abilities. Multiple abilities can be grouped in phases, and phases describe the progression of an adversary. Caldera actively attacks targets by deploying backdoors linked to ATT&CK techniques.

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.

The document proposes a signature-based intrusion detection system using multithreading. It captures network packets and analyzes them for intrusions by comparing signatures to databases of known attacks. A multithreaded design is suggested to improve performance by processing packets in parallel threads. Agents would be deployed on the network with detection modules that use caching of frequent signatures to speed up analysis. An update module would transfer new frequent signatures to the caches.
INTRUSION DETECTION SYSTEM USING CUSTOMIZED RULES FOR SNORTIJMIT JOURNAL
This document proposes an intrusion detection system using customized rules for the Snort tool to improve security. The system uses Wireshark to scan network traffic for anomalies, Snort to detect attacks using customized rulesets for faster response times, and Wazuh and Splunk to analyze log files. Rules are created using the Snorpy tool and added to Snort to monitor for specific attacks like ICMP ping impersonation and authentication attempts. When attacks are attempted, the system successfully detects them and logs the alerts. The integration of these tools provides low-cost intrusion detection capabilities with automated threat identification and faster response compared to existing Snort configurations.

Survey on Host and Network Based Intrusion Detection SystemEswar Publications
With invent of new technologies and devices, Intrusion has become an area of concern because of security issues, in the ever growing area of cyber-attack. An intrusion detection system (IDS) is defined as a device or software application which monitors system or network activities for malicious activities or policy violations. It produces reports to a management station [1]. In this paper we are mainly focused on different IDS concepts based on Host and Network systems.
Survey on classification techniques for intrusion detectioncsandit
Intrusion detection is the most essential component
in network security. Traditional Intrusion
Detection methods are based on extensive knowledge
of signatures of known attacks. Signature-
based methods require manual encoding of attacks by
human experts. Data mining is one of the
techniques applied to Intrusion Detection that prov
ides higher automation capabilities than
signature-based methods. Data mining techniques suc
h as classification, clustering and
association rules are used in intrusion detection.
In this paper, we present an overview of
intrusion detection, KDD Cup 1999 dataset and detai
led analysis of different classification
techniques namely Support vector Machine, Decision
tree, Naïve Bayes and Neural Networks
used in intrusion detection.

This document summarizes various soft computing techniques that can be used for intrusion detection, including fuzzy logic, graph-based approaches, and neural networks. Fuzzy logic can be used to classify parameters and detect anomalies by comparing normal and new fuzzy association rule sets. Graph-based approaches model network traffic as graphs of nodes and edges and use clustering algorithms to detect anomalies. Neural networks can be trained on audit log data to recognize normal behavior and detect deviations that may indicate attacks. These soft computing methods aim to improve on signature-based detection by learning patterns of normal network activity and detecting anomalies.
Intrusion Detection Systems (IDSs) have become widely recognized as powerful tools for identifying, deterring and deflecting malicious attacks over the network. Intrusion detection systems (IDSs) are designed and installed to aid in deterring or mitigating the damage that can be caused by hacking, or breaking into sensitive IT systems. . The attacks can come from outsider attackers on the Internet, authorized insiders who misuse the privileges that have been given them and unauthorized insiders who attempt to gain unauthorized privileges. IDSs cannot be used in isolation, but must be part of a larger framework of IT security measures. Essential to almost every intrusion detection system is the ability to search through packets and identify content that matches known attacks. Space and time efficient string matching algorithms are therefore important for identifying these packets at line rate. In this paper we examine string matching algorithm and their use for Intrusion Detection. Keywords: System Design, Network Algorithm
Optimized Intrusion Detection System using Deep Learning Algorithmijtsrd
A method and a system for the detection of an intrusion in a computer network compare the network traffic of the computer network at multiple different points in the network. In an uncompromised network the network traffic monitored at these two different points in the network should be identical. A network intrusion detection system is mostly place at strategic points in a network, so that it can monitor the traffic traveling to or from different devices on that network. The existing Software Defined Network SDN proposes the separation of forward and control planes by introducing a new independent plane called network controller. Machine learning is an artificial intelligence approach that focuses on acquiring knowledge from raw data and, based at least in part on the identified flow, selectively causing the packet, or a packet descriptor associated with the packet. The performance is evaluated using the network analysis metrics such as key generation delay, key sharing delay and the hash code generation time for both SDN and the proposed machine learning SDN.

Hybrid Intrusion Detection System using Weighted Signature Generation over An...Editor IJMTER
To provide security to network we use existing Intrusion Detection System(IDS) for
identification of known attack with low false alarm,but it is not working when unknown attacks
occurs so to identify unknown attacks we use Anomaly based IDS(ADS) with high false alarm.
HIDS is the combination of IDS and ADS with their advantages for identification of known as well
as unknown attack.IDS used signature based model to identify known attack and ADS used anomaly
based model for identification of unknown attack.HIDS used internet episode rules for identify
known as well as unknown attacks.
EFFICACY OF ATTACK DETECTION CAPABILITY OF IDPS BASED ON ITS DEPLOYMENT IN WI...IJNSA Journal
Intrusion Detection and/or Prevention Systems (IDPS) represent an important line of defence against a variety of attacks that can compromise the security and proper functioning of an enterprise information system. Along with the widespread evolution of new emerging services, the quantity and impact of attacks have continuously increased, attackers continuously find vulnerabilities at various levels, from the network itself to operating system and applications, exploit them to crack system and services. Network defence and network monitoring has become an essential component of computer security to predict and prevent attacks. Unlike traditional Intrusion Detection System (IDS), Intrusion Detection and Prevention System (IDPS) have additional features to secure computer networks.
In this paper, we present a detailed study of how deployment of an IDPS plays a key role in its performance and the ability to detect and prevent known as well as unknown attacks. We categorize IDPS based on deployment as Network-based, host-based, and Perimeter-based and Hybrid. A detailed comparison is shown in this paper and finally we justify our proposed solution, which deploys agents at host-level to give better performance in terms of reduced rate of false positives and accurate detection and prevention.
Network Forensics is scientifically proven technique to accumulate, perceive, identify, examine, associate, analyse and document digital evidence from multiple systems for the purpose of uncovering the fact of attacks and other problem incident as well as performing the action to recover from the attack. Many systems are proposed for designing the network forensic systems. In this paper we have prepared comparative analysis of various models based on different techniques.
An Extensive Survey of Intrusion Detection SystemsIRJET Journal
This document summarizes an extensive survey of intrusion detection systems. It discusses the general architecture of IDS, including host-based and network-based systems. It describes different types of attacks (e.g. DoS, probing, user-to-root) and defenses. It analyzes previous work applying data mining techniques like machine learning to improve detection rates and reduce false alarms. A key problem is the massive number of false alarms that overburden security managers; the document aims to investigate solutions to lower the false alarm rate so that real threats are not missed.

Material management in construction – a case studyeSAT Journals
Abstract
The objective of the present study is to understand about all the problems occurring in the company because of improper application
of material management. In construction project operation, often there is a project cost variance in terms of the material, equipments,
manpower, subcontractor, overhead cost, and general condition. Material is the main component in construction projects. Therefore,
if the material management is not properly managed it will create a project cost variance. Project cost can be controlled by taking
corrective actions towards the cost variance. Therefore a methodology is used to diagnose and evaluate the procurement process
involved in material management and launch a continuous improvement was developed and applied. A thorough study was carried
out along with study of cases, surveys and interviews to professionals involved in this area. As a result, a methodology for diagnosis
and improvement was proposed and tested in selected projects. The results obtained show that the main problem of procurement is
related to schedule delays and lack of specified quality for the project. To prevent this situation it is often necessary to dedicate
important resources like money, personnel, time, etc. To monitor and control the process. A great potential for improvement was
detected if state of the art technologies such as, electronic mail, electronic data interchange (EDI), and analysis were applied to the
procurement process. These helped to eliminate the root causes for many types of problems that were detected.

Life cycle cost analysis of overlay for an urban road in bangaloreeSAT Journals
Abstract
Pavements are subjected to severe condition of stresses and weathering effects from the day they are constructed and opened to traffic
mainly due to its fatigue behavior and environmental effects. Therefore, pavement rehabilitation is one of the most important
components of entire road systems. This paper highlights the design of concrete pavement with added mono fibers like polypropylene,
steel and hybrid fibres for a widened portion of existing concrete pavement and various overlay alternatives for an existing
bituminous pavement in an urban road in Bangalore. Along with this, Life cycle cost analyses at these sections are done by Net
Present Value (NPV) method to identify the most feasible option. The results show that though the initial cost of construction of
concrete overlay is high, over a period of time it prove to be better than the bituminous overlay considering the whole life cycle cost.
The economic analysis also indicates that, out of the three fibre options, hybrid reinforced concrete would be economical without
compromising the performance of the pavement.

Influence of reinforcement on the behavior of hollow concrete block masonry p...eSAT Journals
Abstract
Reinforced masonry was developed to exploit the strength potential of masonry and to solve its lack of tensile strength. Experimental
and analytical studies have been carried out to investigate the effect of reinforcement on the behavior of hollow concrete block
masonry prisms under compression and to predict ultimate failure compressive strength. In the numerical program, three dimensional
non-linear finite elements (FE) model based on the micro-modeling approach is developed for both unreinforced and reinforced
masonry prisms using ANSYS (14.5). The proposed FE model uses multi-linear stress-strain relationships to model the non-linear
behavior of hollow concrete block, mortar, and grout. Willam-Warnke’s five parameter failure theory has been adopted to model the
failure of masonry materials. The comparison of the numerical and experimental results indicates that the FE models can successfully
capture the highly nonlinear behavior of the physical specimens and accurately predict their strength and failure mechanisms.

Influence of compaction energy on soil stabilized with chemical stabilizereSAT Journals
This document summarizes a study on the influence of compaction energy on soil stabilized with a chemical stabilizer. Laboratory tests were conducted on locally available loamy soil treated with a patented polymer liquid stabilizer and compacted at four different energy levels. The study found that increasing the compaction effort increased the density of both untreated and treated soil, but the rate of increase was lower for stabilized soil. Treating the soil with the stabilizer improved its unconfined compressive strength and resilient modulus, and reduced accumulated plastic strain, with these properties further improved by higher compaction efforts. The stabilized soil exhibited strength and performance benefits compared to the untreated soil.

The results found that columns filled with fiber-reinforced concrete exhibited higher stiffness, equal ductility, and enhanced energy absorption compared to those filled with plain concrete. The load carrying capacity increased with fiber content up to 1.5% but not at 2.0%. The analytical predictions of failure load closely matched the experimental values.
Evaluation of punching shear in flat slabseSAT Journals
Abstract
Flat-slab construction has been widely used in construction today because of many advantages that it offers. The basic philosophy in
the design of flat slab is to consider only gravity forces; this method ignores the effect of punching shear due to unbalanced moments
at the slab column junction which is critical. An attempt has been made to generate generalized design sheets which accounts both
punching shear due to gravity loads and unbalanced moments for cases (a) interior column; (b) edge column (bending perpendicular
to shorter edge); (c) edge column (bending parallel to shorter edge); (d) corner column. These design sheets are prepared as per
codal provisions of IS 456-2000. These design sheets will be helpful in calculating the shear reinforcement to be provided at the
critical section which is ignored in many design offices. Apart from its usefulness in evaluating punching shear and the necessary
shear reinforcement, the design sheets developed will enable the designer to fix the depth of flat slab during the initial phase of the
design.

Estimation of surface runoff in nallur amanikere watershed using scs cn methodeSAT Journals
Abstract
The development of watershed aims at productive utilization of all the available natural resources in the entire area extending from
ridge line to stream outlet. The per capita availability of land for cultivation has been decreasing over the years. Therefore, water and
the related land resources must be developed, utilized and managed in an integrated and comprehensive manner. Remote sensing and
GIS techniques are being increasingly used for planning, management and development of natural resources. The study area, Nallur
Amanikere watershed geographically lies between 110 38’ and 110 52’ N latitude and 760 30’ and 760 50’ E longitude with an area of
415.68 Sq. km. The thematic layers such as land use/land cover and soil maps were derived from remotely sensed data and overlayed
through ArcGIS software to assign the curve number on polygon wise. The daily rainfall data of six rain gauge stations in and around
the watershed (2001-2011) was used to estimate the daily runoff from the watershed using Soil Conservation Service - Curve Number
(SCS-CN) method. The runoff estimated from the SCS-CN model was then used to know the variation of runoff potential with different
land use/land cover and with different soil conditions.

Abstract The nonlinear Static procedure also well known as pushover analysis is method where in monotonically increasing loads are applied to the structure till the structure is unable to resist any further load. It is a popular tool for seismic performance evaluation of existing and new structures. In literature lot of research has been carried out on conventional pushover analysis and after knowing deficiency efforts have been made to improve it. But actual test results to verify the analytically obtained pushover results are rarely available. It has been found that some amount of variation is always expected to exist in seismic demand prediction of pushover analysis. Initial study is carried out by considering user defined hinge properties and default hinge length. Attempt is being made to assess the variation of pushover analysis results by considering user defined hinge properties and various hinge length formulations available in literature and results compared with experimentally obtained results based on test carried out on a G+2 storied RCC framed structure. For the present study two geometric models viz bare frame and rigid frame model is considered and it is found that the results of pushover analysis are very sensitive to geometric model and hinge length adopted.

Abstract
Depletion of natural resources and aggregate quarries for the road construction is a serious problem to procure materials. Hence
recycling or reuse of material is beneficial. On emphasizing development in sustainable construction in the present era, recycling of
asphalt pavements is one of the effective and proven rehabilitation processes. For the laboratory investigations reclaimed asphalt
pavement (RAP) from NH-4 and crumb rubber modified binder (CRMB-55) was used. Foundry waste was used as a replacement to
conventional filler. Laboratory tests were conducted on asphalt concrete mixes with 30, 40, 50, and 60 percent replacement with RAP.
These test results were compared with conventional mixes and asphalt concrete mixes with complete binder extracted RAP
aggregates. Mix design was carried out by Marshall Method. The Marshall Tests indicated highest stability values for asphalt
concrete (AC) mixes with 60% RAP. The optimum binder content (OBC) decreased with increased in RAP in AC mixes. The Indirect
Tensile Strength (ITS) for AC mixes with RAP also was found to be higher when compared to conventional AC mixes at 300C.

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.

1. INTRODUCTION
The huge advancement and rapid growth in the internet and
networking has taken this computer era to a whole new
level. However, this highly connected computer era has a
soft spot: The hackers and attackers intentionally or non-
intentionally take down some server system. Either way it
financially costs too much to the company or organization
whose server is under attack. To avoid damage and its cost a
tool called as Intrusion Detection system is used as a last
line of defense against intruders who can have unauthorized
access to the system. Intrusion detection system gives the
assurance of service continuity and data security. The
intruder which firewall fails to detect is detected by the IDS.
Even if firewall and IDS are related to network security, an
IDS varies from a firewall in that a firewall looks for
intrusions outwardly to stop those attacks from affecting the
system by limiting the access between networks and do not
give warning signal about an attack from inside. An IDS
assesses a doubted intrusion which has taken place and
raises an alarm. An IDS also keeps an eye on attacks that
originate from inside of system.
[4]Since the summer of 1999 several DDoS flooding attacks
had been launched on different organizations’ web servers.
The first major DDoS flooding attack occurred, in February
2000, on YAHOO in which all the services provided by
company went offline for about two hours which caused an
immense loss in advertising revenue of company. In October
2002, Domain Name service went offline for about an hour
due to DDoS flooding attack. In February 2004, the website
of SCO Group was attacked. On September 18, 2010, in
USA a website of MPAA was inaccessible to internet users
for over twenty hours of time because of DDoS flooding
attack.
The remaining paper is structured as: Section 2 describes the
classification of IDS. Section 3 categorizes the different
types of application layer DDoS flooding attack. In section
4, some papers in literature are surveyed. Section 5
introduces to Naïve Bayes algorithm. Section 6 proposes an
efficient intrusion detection system based on machine
learning technique. Section 7 concludes the paper.
2. CLASSIFICATION OF INTRUSION
DETECTION SYSTEM
IDS are of two types: Host based and Network based.
1. Host Intrusion Detection System (HIDS): HIDS run
on network devices or different hosts. A Host
Intrusion Detection System keeps tabs on the inward
bound and outward bound packets from the device
and will alert the admin if doubtful activity is
spotted. It takes a snap of existing system files and
compares it to the previous one. If the critically
important system files were altered or deleted, the
admin is alerted for investigation.
2. Network Intrusion Detection system (NIDS): NIDS
are deployed at strategic points within the network
to keep tabs on traffic coming in and going out from
all network devices. It analyses traffic on the whole
subnet and matches it with the traffic passed on the

is detected.
All IDS use any one of the following techniques for
intrusion detection:
1. Anomaly based IDS: These types of IDS will keep
an eye on network activity and compare it with
recognized baseline-data. The baseline-data will
identify normal traffic for that network. Also it will
identify normally used bandwidth, protocols and
ports and alert the admin when traffic is detected
which is atypical, or considerably different as
compared to baseline-data. The problem is that it
raises a false positive alarm for a genuine user if the
baseline-data is not configured intelligently.
2. Signature based IDS: A signature based IDS will
keep an eye on packets in the network and compare
them with a signatures database or features of
previously known threats. But the similarity between
them is that most of the antivirus software detects
malware. The problem is that there will be a delay
between a novel threat being discovered and the
signature for identifying that threat being applied to
IDS. During that delay gap IDS can’t detect new
threat.
3. CATEGORIZATION OF APPLICATION
LAYER DDoS FLOODING ATTACK
The application layer attacks cause exhaustion of server
resources and thus cause the disruption in legitimate user’s
services. Application-level DDoS attacks use low
bandwidth. These attacks look stealthier in appearance as
they are very similar to benignant network traffic. They are
non-volumetric. The most common attacks at application
layer are DNS amplification flooding attack and SIP
flooding attack. While major types of recent DDoS flooding
attacks are those which use HTTP protocol.
1. Reflection based flooding attacks: In these attacks,
attacker sends forged application layer protocol
requests to large number of reflectors. Two main
attacks in this category are SIP flooding and DNS
amplification attacks.
2. HTTP flood attacks: It consists of seemingly
legitimate session-based sets of HTTP_GET or
_POST requests sent to a victim web server. These
requests are consume a major amount of the server’s
resources. It can result in DoS without essentially
needing a high-rate of traffic in the network. These
types of requests are every so often sent all together
by means of a number of bots, increasing the
intensity of the attack.
4. LITERATURE SURVEY
In paper [1] authors proposed a neural network approach. A
MLP is used for detection of intrusion, established on an
off-line analysis method. This research targets to resolve a
multi-class problem in which the different attack type is also
identified by the neural network besides detecting whether it
is a normal request or an attack. To find the optimal neural
network, various neural networks are surveyed, with
respects to the number of unseen layers. An early ending
validation is also applied in the learning/training stage to
gain the increase in the capability of the neural network
generalization. The results describe that the given system
classifies the records with about 91% accurateness with two
unseen neuron layers and 87% accurateness with one unseen
layer in the neural network.
Paper [2] suggests a layered framework combined with
neural network to build an effective intrusion detection
system. This system has been tested with Knowledge
Discovery & Data Mining (KDD) 1999 dataset. The
comparison of the systems is done with the current
techniques which either use neural network layered
framework. The outcome indicates that the proposed system
has high attack detection accuracy and less false alarm rate.
The results show that there is still opportunity to improve
results as the given systems are not able to detect each
attack, so it is encouraging to consider investigating in this
path.
In paper [3] authors applied two of the efficient data mining
algorithms called Naive Bayes and trees augmented Naive
Bayes for detecting the intruders in the network and the
results are compared with decision tree and SVM. They
presented experimental results on NSL-KDD data set and
then observed that their intrusion detection system has
higher detection rate and lower false positive rate.
According to the results, Naive-Bayes is found less time
consuming. TAN has better accuracy rate and detection rate,
and also has less false positive rate.
The paper [4] classifies the different DDoS attacks based on
the deployment location, time at which they are detected,
etc. Depending on these types different IDS types are
categorized. This paper proposes a hybrid IDS, which is
cannot be applied practically now but may be in future. But
this paper also tells that the application layer DDoS flooding
attacks is the largest threat because they are increasing
speedily. They are stealthier as compared to DDoS attacks at
other layers and they masquerade as flash crowds.
The authors in paper [5] discuss the variations in network-
based and host-based intrusion detection approaches to show
the together can provide additionally effective detection and
prevention of intrusion. They propose a hybrid IDS
combining host IDS and network IDS, with misuse detection
anomaly detection techniques, uses few auditing programs
to sort an wide-ranging feature set that describes host
session or every network connectivity, and applies data
mining to study guidelines that precisely capture the
behavior of intruders and normal users. But there are still
many practical and theoretical problems to be fixed, and
many significant technologies are needed to study deeper.
The experimental research shows that the design and
implementation of accurate & efficient IDS built on data-
mining is big and difficult project.

Authors employed an FC-ANN method in [6] to solve
weaker detection stability and the lower detection accuracy
issues with the use of restore point. In this paper fuzzy
clustering technique is used to classify dataset into several
subsets. These different subsets are used to train dataset.
Then ANN learns the pattern of every subset. ANN is feed
forward network consists of neuron with each neuron having
independent processing unit. To reduce the complexness and
subset size, different training subsets are generated by fuzzy
clustering. Different ANN models are trained using those
subsets and at last results are merged.
In paper [7], Devikrishna K. S. and Ramakrishna B. B.
proposed a system using Multi-Layer Perceptron (MLP).
Artificial neural network consists of neurons. Each neuron is
an autonomous processing unit. The output from every
neuron is sent to the neuron of next layer. In neural network
input parameters consist of information extracted from
network connection and output parameter class of
connections like normal or attack. In this paper Multilayer
Perceptron is used for intrusion detection. In this system
input is mapped to appropriate output. After detecting the
attack, attack is classified in to 6 types by different layers of
neuron. Authors pointed out the problem of obtaining
irrelevant result and suggest solving it in future work.
Numerous concerns came up from this study such as large
training time, incorrect detection, more false positive rate,
attack classification etc. It is essential to use high-speed
machine learning technique for IDS, to solve the problem of
training time and comparing the results with existing
machine learning techniques. In this survey, a technique is
proposed which will lessen the training time and
accurateness of detection.
5. NAÏVE BAYES (NB) CLASSIFIER
ALGORITHM
Naïve Bayes (NB) is the probabilistic classifier. It is based
on the Bayes’ theorem, in probability theory and statistics,
with strong independence assumptions between different
features related to a particular dataset. Simply it assumes
that the existence of a particular property of a class is
unrelated to the existence of any other property. It
outperforms other classification techniques such as random
forest, boosted trees, decision tree, etc. Methods such as
clustering and nearest neighbor are mostly used with
numeric data. However, data related to networks use
categorical values like protocol_type, service, logged_in,
etc. Advantage of using Naïve Bayes is that it requires a
small database for training purpose. It is not sensitive to
irrelevant features.
Bayes Theorem which is used by Bayesian Classifier states:
P(sj|r) = p(r|sj)p(sj)/p(r)
• p(sj|r) = probability of instance r being in class sj
This needs to be computed.
• p(r|sj) = probability of causing r in sj
We can imagine as- r is in sj, causes us to feature r with
some probability.
• p(sj) = probability of sj’s occurence
This is just how frequent the class sj, is in the given dataset.
• p(r) = probability of r’s occurrence
This can actually be ignored, since it is same for all classes.
6. PROPOSED SYSTEM
It is observed that, from the survey of papers in the
literature, there are some issues such as time-consuming
training, low detection, less accuracy in the detection and
classification of attacks, etc. So, we must find some other
approach which can work on these problems. In theory, it is
found that Naïve Bayes (NB) algorithm provides fast
learning/training speed than existing machine learning
algorithm. Therefore the proposed approach is to build an
analytical model for intrusion detection which will have a
fast learning/training ability than any other existing
approach. Using NB method a classifier will be built to
differentiate between usual and unusual activity. The results
of NB algorithm will be compared with existing intrusion
detection approach.
