1.1 INTRODUCTION
The development in science and technology are so rapid that the
development and existence of mankind is dependent on the
implementation of scientific knowledge. The entire world is paying
much attention to improve the file style by synthesizing the result
of gaining the classical as well as modern knowledge. No country
can move in phase with the time. Under such circumstances
computerization techniques takes its role. The main problem arising
in a network is the question of security, which means protection
from attacks. The project entitled Network Intrusion Detection
System tries to trace out the intruder packets using IP Address or
data and decides if it is to be forwarded and assures security. The
project entitled Network Intrusion Detection System is an IDS where
it monitors packets on the network wire and attempts to the
discovery of hacker/cracker who is attempting to break into system
This discovery is being performed by comparing the captured packet
with the intruder details stored in the database .If the packet is
found to be an intruder it is then forwarded to the firewall with
the respective message for blocking. The software is developed
using C#.Net as the frontend and SQL Server as the Back-end. The
system can be implemented in Windows NT Platform. The project
ensures more security, accuracy, and efficiency to the system. All
intrusion-detection systems tested were susceptible to
packet spoofing which tricks the server into thinking packets
have come from a trusted host or into using its own
intrusiondetection counter measures to cut connectivity to
legitimate
7 sites. The systems were also found that flood networks devices
with to too be many vulnerable requests to for packet fragmentation
attacks, and to denial-of-service attacks connections, which can
cause them to shut down. The project entitled NETWORK INTRUSION
DETECTION SYSTEM provides server side security for network
intrusion through packet sniffing and analysis and pattern
matching. The filtering mechanism usually can filter IP packets
based on some or all of the following conditions: Source IP
address, the system from which the packet originated Destination IP
address, the system for which the packet is destined Protocol
Source TCP/UDP port, the port number of the service on the host
originating connection Destination TCP/UDP port String match in a
packet.

SYSTEM ANALYSIS PHASE

2.1 Existing system
The existing Network Intrusion Detection System is a Windows
based system developed internally by the company. It is the manual
encoding of the expert system hence responding properly only to
known attacks. This is an ordinary system that can be used to
detect only a known or ungeneralised set of users. The main
drawback lies in the fact that the system cannot be generalized.
The system acts as a subsystem of the firewall itself. The system
contains the details of the intruder, which is then forwarded to
the firewall.
10 2.2. Proposed system The proposed system is a Network
Intrusion Detection System that is an enhancement of the existing
system. It is a system level program that works as the lower layer
for of the firewall. The system checks If the database the already
registered intruders. found
intruding, they are forwarded to the firewall for blocking. The
firewall is responsible for the blocking of the packet.

DESIGN PHASE
12
3.1 Module design
Modular design means breaking the program tasks into small
parts. The advantage of modularity is in easy accessing of coding
and debugging, also more number of programs can engage in a
Software development and the work could be finished within a
targeted minimum span of time by splitting the program into small
parts.
This project is mainly classified into seven modules Action
Intrusion Modal Traffic Sniffing Detection Reports
13 Main modules are sub divided follows. ACTION - Security
Application Lock Application Exit INTRUSION - Registration (IP)
Reg.Alter Reg.Removal MODAL - Registration Name Reg.Alter

details regarding these modules are as
14 The project is mainly developed in the background view of
administrator. This Software has been mainly divided into seven to
eight modules, starting with Action to Reports. The first module
Action expresses the ability of administrator to handle the entire
control by providing security using password, also through locking
application. The second module Intrusion does the job of fixing IP
addresses of systems with the assumption that they are intruders.
It also provides the options for updating/dropping of registration.
The third module Modal also has the same work of Intrusion except
the fact that it registers the intruder with the predetermined
information about intruder. The fourth module Traffic displays the
packet details based on the source or destination IP. It displays
the available ports in the system, also the connectivity between
systems in the network are checked and give the responds through
the ping machine form. The fifth module Sniffing gives the details
of packets on the basis of different network protocols. In the
Detection module new and existing intruders are detected and
displayed. It also monitors the data part included in the packets.
The last module Report gives the entire details of intruder.
15 3.2 Input design
To ensure that input is understood by the user. Input design is
one of the most expensive phases of the operation of computerized
system and is often the major problem of a system. A larger number
of problems with a system can usually be traced back to fault input
design and method. Needless to say, therefore that the input data
is the life block of a system and has to be analyzed and designed
with the most consideration. The decisions made during the input
design are: To provide cost effective method of input. To achieve
the highest possible level of accuracy. System analysts decide the
following input design details like, what data item to input, what
medium to use, how the data should be arranged or coded data items
and transaction needing validations to detect errors and at last
the dialogue to guide users in providing input. Input data of a
system may not be necessarily a raw data captured in the system
form scratch. These can also be the output of another system or
sub-system. The design of input covers all phases of input from the
certain of initial data to actual entering the data to the system
for processing. The design of inputs data involves for identifying
the data and needed, ensuring specifying the characteristics of
each data item, capturing and preparing computer processing
correctness of data.
16 Input forms are: Login Form Using this form the administrator
can login to the application. Change Security Form By using this
form the administrator can change his password. Intruder
registration Form This form used for the registration of new
intruders. Intruder alteration Form Intruder alteration is
performed by the use of this form. Adaptive model registration Form
New unwanted commands are registered in this form. Adaptive model
modification Form Using this form we can modify unwanted commands.
Locking Form Using this form the administrator can lock the
application from the unauthorized users.
17 3.3 Database design Database design is required to manage the
large bodies of information. definition addition of the The
management of the must of data involves of for both the and of to
structure db storage provide the information the safety due
provisions of mechanism for the manipulation of information. In
system information handled, despite system crashes
attempts art unauthorized access. For developing an efficient
db, we will have to fulfill certain condition such as: Control
redundancy. Ease of use. Data independence. Accuracy and integrity.
Avoiding inordinate delays. Recovery form failure. Privacy and
security. Performance. There are 6 major steps in design process.
The first 5 steps are usually done on paper and finally the design
is implemented. Identify the table and relationships Identify the
data that is needed for each table and relationship Resolve the
relationship. Verify the design. Implement the design

3.4 DATA FLOW DIAGRAM
20 Data Flow Diagram (DFD) is used to define the flow of the
system and its resources such as information. Data Flow Diagrams
are a way of expressing system requirements in a graphical manner.
DFD represents one of the most ingenious tools used for structured
analysis. A DFD is also known as a bubble chart. It has the purpose
of clarifying system requirements and identifying major
transformations that will become programs in system design. In the
normal convention, logical DFD can be completed using only 4
notations. : Represents source or destination of data.
Represents data flow.
Represents a process that transforms incoming data into outgoing
flow.
Represents data store.
21 The DFD at the simplest level is referred to as the CONTEXT
ANALYSIS DIAGRAM. These are expanded by level, each explaining its
process in detail. Processes are numbered for easy identification
and are normally labeled in block letters. Each Data flow is
labeled for easy understanding.

4.3. SOFTWARE DESCRIPTION
The software NIDS is going to develop under the background of
.NET framework. Even though .NET frame work support more than 20
languages, C# is the powerful language that has the ability to
compete with JAVA, since it is the only .NET language that comes
under the ECMA (European Computer Manufacturing Association)
standard. VB.net has backward compatibility with old Visual basic.
So, it supports old vb functions. C# is a fresh, clean language. So
strongly support using C# instead of VB.net just for this clean
compiler. An important factor in .NET framework, called
optimization makes a big difference between JAVA and C# and it
takes C# to sit in front of JAVA. Finally the splendid features of
.NET, like object oriented, platform independence (at certain
limits), etc makes the language C# more closer to the users
mind.

ADO.NET Microsoft In Windows ADO programs introduced a the ADO
introduced a simple object model that made straightforward
addition,
concept of disconnected record sets as a way to transport data
between the tires of distributed applications. The lowlevel API
behind ADO which is called OLE DB.ADO.NET was designed with the
disconnected data in mind, because this stateless approach works
best for distributed Internet applications. ADO.NET contains two
sets of similar classes. One set is a generic set of classes that
can be used to access all databases that have OLE DB provider and a
set of classes for Microsofts SQL Server. ADO.NET COMPONENTS The
ADO.NET components have been designed to factor data access from
data manipulation. There are two
30 central components of ADO.NET that accomplish this the
Dataset, and the .NET data provider, which is a set of components
including the Connection, Command, Data Reader, and Data Adapter
objects. The ADO.NET Dataset is the core component of the
disconnected architecture of ADO.NET. The Dataset is explicitly
designed for data access independent of any data source. As a
result it can be used with multiple and differing of any data
sources, used with XML data, or used to manage data local to the
application.

access to data. The connection object provides connectivity to a
data source. The Common objects enables access to database commands
to return data, modify data, run stored procedures, and sends or
retrieve parameter information. The Data Reader provides a high -
performance stream of data from the data source. Finally, the Data
Adapter provides the bridge between the Dataset object and the data
source.Implementing OLEDB is ADO.NET. applications (XML). ADO.Net

ASP.NET technology used to create programmable web pages. They can
present information, using any mark-up language, to the user in any
browser and use code on the server to implement application logic.
ASP.NET is the next version of Active Server Pages (ASP); it is a
unified Web development platform that provides the services
necessary for developers to build enterprise-class Web
applications. Developers can choose from the following two features
when creating an ASP.NET application, Web Forms and Web services,
or combine these in any way they see fit. Web Forms allows you to
build powerful forms-based Web pages. When building these pages,
you can use ASP.NET server controls to create common UI elements,
and program them for common tasks. These controls allow you to
rapidly build a Web Form out of reusable built-in or custom
components, simplifying the code of a page. ASP.NET

4.3.2 . MICROSOFT SQL SERVER 7.0 Relational database systems are
the most
important database systems used in the software industry today.
One of the most outstanding systems is Microsoft SQL Server. SQL
Server is a relational database system developed and marketed by
Microsoft. This system is the most important part of Microsoft Back
Office, an enterprise suite of client server applications .It runs
exclusively under Windows NT, Windows 95/98, and Windows 2000
Server. The most important aspects of SQL Server 7 are:
SQL Server works as a natural extension of Windows NT because it
is so closely integrated with this operating system. As such the
user does not have to learn another user interface to work with
this database system.
SQL Server is easy to use. SQL Server has the same easy set up
and maintenance SQL Server uses services of Windows NT to offer new
or extended security. database capabilities such as sending and
receiving messages, and managing login SQL Server scales from a
