ABSTRACT
Nowadays it is very important to maintain a high level security to ensure safe and trusted communication
of information between various organizations. But secured data communication over internet and any
other network is always under threat of intrusions and misuses. So Intrusion Detection Systems have
become a needful component in terms of computer and network security. There are various approaches
being utilized in intrusion detections, but unfortunately any of the systems so far is not completely
flawless. So, the quest of betterment continues. In this progression, here we present an Intrusion
Detection System (IDS), by applying genetic algorithm (GA) to efficiently detect various types of network
intrusions. Parameters and evolution processes for GA are discussed in details and implemented. This
approach uses evolution theory to information evolution in order to filter the traffic data and thus reduce
the complexity. To implement and measure the performance of our system we used the KDD99
benchmark dataset and obtained reasonable detection rate.

1. INTRODUCTION
In 1987 Dorothy E. Denning proposed intrusion detection as is an approach to counter the
computer and networking attacks and misuses [1]. Intrusion detection is implemented by an
intrusion detection system and today there are many commercial intrusion detection systems
available. In general, most of these commercial implementations are relative ineffective and
insufficient, which gives rise to the need for research on more dynamic intrusion detection
systems.
Generally an intruder is defined as a system, program or person who tries to and may become
successful to break into an information system or perform an action not legally allowed [2]. We
refer intrusion as any set of actions that attempt to compromise the integrity, confidentiality, or
availability of a computer resource [3]. The act of detecting actions that attempt to compromise
the integrity, confidentiality, or availability of a computer resource can be referred as intrusion
detection [3]. An intrusion detection system is a device or software application that monitors
network and/or system activities for malicious activities or policy violations and produces
reports [4].

The remainder of the paper is organized as follows: Section 2 shortly describes some previous
works. Section 3 gives an overview about intrusion detection system. Section 4 describes some
existing intrusion detection systems and their problems. Section 5 and 6 describes our system
and its implementation. Section 7 describes the performance analysis of our system. We
conclude at section 8.
2. RELATED WORKS
Some import applications of soft computing techniques for Network Intrusion Detection
is described in this section. Several Genetic Algorithms (GAs) and Genetic
Programming (GP) has been used for detecting intrusion detection of different kinds in
different scenarios. Some uses GA for deriving classification rules [5][6][7][8]. GAs
used to select required features and to determine the optimal and minimal parameters of
some core functions in which different AI methods were used to derive acquisition of
rules [9][10][11]. There are several papers [12][13][14][15] related to IDS which has
certain level of impact in network security.
The effort of using GAs for intrusion detection can be referred back to 1995, when
Crosbie and Spafford [16] applied the multiple agent technology and GP to detect
network anomalies [19]. For both agents they used GP to determine anomalous network
behaviours and each agent can monitor one parameter of the network audit data. The
proposed methodology has the advantage when many small autonomous agents are used
but it has problem when communicating among the agents and also if the agents are not
properly initialized the training process can be time consuming.
Li [6] described a method using GA to detect anomalous network intrusion [19][20].
The approach includes both quantitative and categorical features of network data for
deriving classification rules. However, the inclusion of quantitative feature can increase
detection rate but no experimental results are available.
Goyal and Kumar [18] described a GA based algorithm to classify all types of smurf
attack using the training dataset with false positive rate is very low (at 0.2%) and
detection rate is almost 100% [20].
Lu and Traore [7] used historical network dataset using GP to derive a set of
classification [19]. They used support-confidence framework as the fitness function and
accurately classified several network intrusions. But their use of genetic programming
made the implementation procedure very difficult and also for training procedure more
data and time is required
Xiao et al. [17] used GA to detect anomalous network behaviours based on information
theory [19][20]. Some network features can be identified with network attacks based on
mutual information between network features and type of intrusions and then using
these features a linear structure rule and also a GA is derived. The approach of using
mutual information and resulting linear rule seems very effective because of the reduced
complexity and higher detection rate. The only problem is it considered only the
discrete features.
Gong et al. [19] presented an implementation of GA based approach to Network Intrusion
Detection using GA and showed software implementation. The approach derived a set of
classification rules and utilizes a support-confidence framework to judge fitness function.

111
Abdullah et al. [20] showed a GA based performance evaluation algorithm to network intrusion
detection. The approach uses information theory for filtering the traffic data.
3. INTRUSION DETECTION OVERVIEW
The below sections give a short overview of networking attacks, classifications and various
components of Intrusion Detection System.
3.1. Networking Attacks
This section is an overview of the four major categories of networking attacks. Every attack on
a network can comfortably be placed into one of these groupings [21].
Denial of Service (DoS): A DoS attack is a type of attack in which the hacker makes a
computing or memory resources too busy or too full to serve legitimate networking
requests and hence denying users access to a machine e.g. apache, smurf, neptune, ping
of death, back, mail bomb, UDP storm etc. are all DoS attacks.
Remote to User Attacks (R2L): A remote to user attack is an attack in which a user
sends packets to a machine over the internet, which s/he does not have access to in
order to expose the machines vulnerabilities and exploit privileges which a local user
would have on the computer e.g. xlock, guest, xnsnoop, phf, sendmail dictionary etc.
User to Root Attacks (U2R): These attacks are exploitations in which the hacker starts
off on the system with a normal user account and attempts to abuse vulnerabilities in the
system in order to gain super user privileges e.g. perl, xterm.
Probing: Probing is an attack in which the hacker scans a machine or a networking
device in order to determine weaknesses or vulnerabilities that may later be exploited so
as to compromise the system. This technique is commonly used in data mining e.g.
saint, portsweep, mscan, nmap etc.
3.2. Classification of Intrusion Detection
Intrusions Detection can be classified into two main categories. They are as follow:
Host Based Intrusion Detection: HIDSs evaluate information found on a single or
multiple host systems, including contents of operating systems, system and application
files [22].
Network Based Intrusion Detection: NIDSs evaluate information captured from
network communications, analyzing the stream of packets which travel across the
network [22].
3.3. Components of Intrusion Detection System
An intrusion detection system normally consists of three functional components [23].
The first component of an intrusion detection system, also known as the event generator, is a
data source. Data sources can be categorized into four categories namely Host-based monitors,
Network-based monitors, Application-based monitors and Target-based monitors.
The second component of an intrusion detection system is known as the analysis engine. This
component takes information from the data source and examines the data for symptoms of
attacks or other policy violations. The analysis engine can use one or both of the following
analysis approaches:
Misuse/Signature-Based Detection: This type of detection engine detects intrusions
that follow well-known patterns of attacks (or signatures) that exploit known software

112
vulnerabilities [24][25]. The main limitation of this approach is that it only looks for the
known weaknesses and may not care about detecting unknown future intrusions [26].
Anomaly/Statistical Detection: An anomaly based detection engine will search for
something rare or unusual [26]. They analyses system event streams, using statistical
techniques to find patterns of activity that appear to be abnormal. The primary
disadvantages of this system are that they are highly expensive and they can recognize
an intrusive behavior as normal behavior because of insufficient data
The third component of an intrusion detection system is the response manager. In basic
terms, the response manager will only act when inaccuracies (possible intrusion attacks)
are found on the system, by informing someone or something in the form of a response.
4. EXISTING SYSTEMS AND THEIR PROBLEMS
Here we describe some of the important Intrusion Detection systems and their problems.
4.1. Existing Intrusion Detection Systems
Snort: A free and open source network intrusion detection and prevention system, was
created by Martin Roesch in 1998 and now developed by Sourcefire. In 2009, Snort
entered InfoWorld's Open Source Hall of Fame as one of the “greatest open source
software of all time” [36][37]. Through protocol analysis, content searching, and
various pre-processors, Snort detects thousands of worms, vulnerability exploit
attempts, port scans, and other suspicious behavior [34][35].
OSSEC: An open source host-based intrusion detection system, performs log analysis,
integrity checking, rootkit detection, time-based alerting and active response [34][35].
In addition to its IDS functionality, it is commonly used as a SEM/SIM solution.
Because of its powerful log analysis engine, ISPs, universities and data centers are
running OSSEC HIDS to monitor and analyze their firewalls, IDSs, web servers and
authentication logs.
OSSIM: The goal of Open Source Security Information Management, OSSIM is to
provide a comprehensive compilation of tools which, when working together, grant
network/security administrators with a detailed view over each and every aspect of
networks, hosts, physical access devices, and servers [35]. OSSIM incorporates several
other tools, including Nagios and OSSEC HIDS.
Suricata: An open source-based intrusion detection system, was developed by the Open
Information Security Foundation (OISF) [38].
Bro: An open-source, Unix-based network intrusion detection system [39]. Bro detects
intrusions by first parsing network traffic to extract its application-level semantics and
then executing event-oriented analyzers that compare the activity with patterns deemed
troublesome.
Fragroute/Fragrouter: A network intrusion detection evasion toolkit [34]. Fragrouter
helps an attacker launch IP-based attacks while avoiding detection. It is part of the
NIDSbench suite of tools by Dug Song.
BASE: The Basic Analysis and Security Engine, BASE is a PHP-based analysis engine
to search and process a database of security events generated by various IDSs, firewalls
and network monitoring tools [34].
Sguil: Sguil is built by network security analysts for network security analysts [34][35].
Its main component is an intuitive GUI that provides real-time events from

113
Snort/barnyard. It also includes other components which facilitate the practice of
network security monitoring and event driven analysis of IDS alerts.
4.2. Problems with Existing Systems
Most existing intrusion detection systems suffer from at least two of the following problems [2]:
First, the information used by the intrusion detection system is obtained from audit
trails or from packets on a network. Data has to traverse a longer path from its origin to
the IDS and in the process can potentially be destroyed or modified by an attacker.
Furthermore, the intrusion detection system has to infer the behavior of the system from
the data collected, which can result in misinterpretations or missed events. This is
referred as the fidelity problem.
Second, the intrusion detection system continuously uses additional resources in the
system it is monitoring even when there are no intrusions occurring, because the
components of the intrusion detection system have to be running all the time. This is the
resource usage problem.
Third, because the components of the intrusion detection system are implemented as
separate programs, they are susceptible to tampering. An intruder can potentially
disable or modify the programs running on a system, rendering the intrusion detection
system useless or unreliable. This is the reliability problem.
5. OUR IDS USING GENETIC ALGORITHM
We have chosen GA to make our intrusion detection system. This section gives an overview of
the algorithm and the system.
5.1. Genetic Algorithm Overview
A Genetic Algorithm (GA) is a programming technique that mimics biological evolution as a
problem-solving strategy [27]. It is based on Darwinian’s principle of evolution and survival of
fittest to optimize a population of candidate solutions towards a predefined fitness [6].
GA uses an evolution and natural selection that uses a chromosome-like data structure and
evolve the chromosomes using selection, recombination and mutation operators [6]. The process
usually begins with randomly generated population of chromosomes, which represent all
possible solution of a problem that are considered candidate solutions. From each chromosome
different positions are encoded as bits, characters or numbers. These positions could be referred
to as genes. An evaluation function is used to calculate the goodness of each chromosome
according to the desired solution; this function is known as “Fitness Function”. During the
process of evaluation “Crossover” is used to simulate natural reproduction and “Mutation” is
used to mutation of species [6]. For survival and combination the selection of chromosomes is
biased towards the fittest chromosomes.
When we use GA for solving various problems three factors will have vital impact on the
effectiveness of the algorithm and also of the applications [19]. They are: i) the fitness function;
ii) the representation of individuals; and iii) the GA parameters. The determination of these
factors often depends on applications and/or implementation.

114
5.2. Flowchart
Figure 1 shows the operations of a general genetic algorithm according to which GA is
implemented into our system.
Figure 1. Flowchart of Genetic Algorithm
5.3. Algorithm of Our System
Our system can be divided into two main phases: the precalculation phase and the detection
phase. Listing 1 depicts major steps in precalculation phase, where a set of chromosome is
created using training data. This chromosome set will be used in the next phase for the purpose
of comparison.
Listing 1. Major steps in precalculation

Output : A set of chromosomes

2. For each training data
3. If it has neighboring chromosome within Range
4. Merge it with the nearest chromosome
5. Else
6. Create new chromosome with it
7. End if
8. End for
Listing 2 depicts major steps of detection phase, where a population is being created for a test
data and going through some evaluation processes (selection, crossover, mutation) the type of
the test data is predicted. The precalculated set of chromosome is used in this phase to find out
fitness of each chromosome of the population.

6. OUR IMPLEMENTATION
To implement our algorithm and to evaluate the performance of our system, we have used the
standard dataset used in KDD Cup 1999 “Computer network intrusion detection” competition.
6.1. KDD Sample Dataset
For the implementation of our algorithm we used the KDD 99 intrusion detection datasets
which are based on the 1998 DARPA initiative, which provides designers of intrusion detection
systems (IDS) with a benchmark on which to evaluate different methodologies [28][32]. Hence,
a simulation is being made of a factitious military network with three ‘target’ machines running
various operating systems and services. They also used three additional machines to spoof
different IP addresses for generate network traffic.
A connection is a sequence of TCP packets starting and ending at some well defined times,
between which data flows from a source IP address to a target IP address under some well
defined protocol [28][29][32]. It results in 41 features for each connection.
Finally, there is a sniffer that records all network traffic using the TCP dump format [32]. The
total simulated period is seven weeks. Normal connections are created to profile that expected in
a military network and attacks fall into one of four categories: User to Root; Remote to Local;
Denial of Service; and Probe.
The KDD 99 intrusion detection benchmark consists different components [30]:
kddcup.data; kddcup.data_10_percent; kddcup.newtestdata_10_percent_unlabeled;
kddcup.testdata.unlabeled; kddcup.testdata.unlabeled_10_percent; corrected.
We have used “kddcup.data_10_percent” as training dataset and “corrected” as testing dataset.
In this case the training set consists of 494,021 records among which 97,280 are normal
connection records, while the test set contains 311,029 records among which 60,593 are normal
connection records. Table 1 shows the distribution of each intrusion type in the training and the
test set.

116
Table 1. Distribution of intrusion types in datasets
Dataset normal probe dos u2r r2l Total
Train (“kddcup.data_10_percent”) 97280 4107 391458 52 1124 494021
Test (“corrected”) 60593 4166 229853 228 16189 311029
6.2. Implementation Procedure
In the precalculation phase, we have made 23 groups of chromosomes according to training
data. There were 23 (22+1) groups for each of attack and normal types presented in training
data. Number of chromosomes in each group is variable and depends on the number of data and
relationship among data in that group. Total number of chromosomes in all groups were tried to
keep in reasonable level to optimize time consumption in testing phase.
In the testing / detection phase, for each test data, an initial population is made using the data
and occurring mutation in different features. This population is compared with each
chromosomes prepared in training phase. Portion of population, which are more loosely related
with all training data than others, are removed. Crossover and mutation occurs in rest of the
population which becomes the population of new generation. The process runs until the
generation size comes down to 1 (one). The group of the chromosome which is closest relative
of only surviving chromosome of test data is returned as the predicted type.
Among the extracted features of the datasets, we have taken only the numerical features, both
continuous and discrete, under consideration for the sake of the simplification of the
implementation.
7. EXPERIMENTAL RESULTS AND ANALYSIS
From our system we get the confusion matrics depicted in table 2. For most of the classes, our
system performs well enough except normal data type which is because of ignoring non-
numerical features. Comparing with the confusion matrics of the winning entry of KDD’99
[31], we get better detection rate for denial of service & user-to-root and close detection rate for
probe & remote-to-local.

%Correct 76.9% 54.7% 92.0% 6.4% 50.0%
For simplified evaluation of our system, besides the classical accuracy measure, we have used
two standard metrics of detection rate and false positive rate developed for network intrusions
derived in [33]. Table 3 shows these standard metrics.

Actual Class
Normal True Negative (42138) False Positive (18455)
Intrusion False Negative (12528) True Positive (237908)
Detection rate for each data type can be seen from figure 2.
Figure 2. Detection rate for each class
Detection rate (DR) is calculated as the ratio between the number of correctly detected
intrusions and the total number of intrusions [33], that is:
Using table 3, detection rate, DR = 0.9500.
False positive rate (FP) is calculated as the ratio between the numbers of normal connections
that are incorrectly classifies as intrusions and the total number of normal connections [33], that
is:
Using table 3, false positive rate, FP = 0.3046.
8. CONCLUSIONS
In this paper, we present and implemented an Intrusion Detection System by applying genetic
algorithm to efficiently detect various types of network intrusions. To implement and measure
the performance of our system we used the standard KDD99 benchmark dataset and obtained
reasonable detection rate. To measure the fitness of a chromosome we used the standard
deviation equation with distance. If we can use a better equation or heuristic in this detection
process we believe the detection rate and process will improve a great extent, especially false
positive rate will surely be much lower. In near future we will try to improve our intrusion
detection system with the help of more statistical analysis and with better and may be more
complex equations.
