The Firewalls and Internet Security seminar defines three basic types of firewalls: packet filters, circuit level gateways, and application gateways. Of course there are also hybrid firewalls, which can be combinations of all three.
Packet filter gateways are usually comprised of a series of simple checks based on the source and destination IP address and ports. They are very simple to the user since it will probably not even realize that the checks are taking place (unless of course it was denied!!). However, that simplicity is also their bi ....etc

The Geometric Efficient Matching Algorithm for Firewalls




Existing System:
Existing algorithms implement the “longest prefix match” semantics, using several different approaches. The IPL algorithm, which is based on results, divides the search space into elementary intervals by different prefixes for each dimension, and finds the best (longest) match for each such interval. Firewall statefulness is commonly imple ....etc

No one could have ever imagined that the immense potential and benefits of creating and using small as well as large networks would also come packed with a hidden factor which would make the network highly vulnerable to the outside world and its miscreants. Networks and the Internet are rapidly expanding sectors of the computing market. Many companies, organizations, and indeed individuals have installed such systems without realizing the risks they are running. This paper examines those risks and their solutions. Since the advent of the Inter ....etc

Computers and Networking have become inseparable by now. A number of confidential transactions occur every second and today computers are used mostly for transmission rather than processing of data. So Network Security is needed to prevent hacking of data and to provide authenticated data transfer. Network Security can be achieved by Firewall. Conventional firewalls rely on the notions of restricted topology and controlled entry points to function. Restricting the network topology, difficulty in filtering of certain protocols, End-t ....etc

ABSTRACT

Template matching is an object detection technique in image processing to find small parts of an image which match a template image. There are many methods one can adopt for this purpose.

Matching can be Template based, in which case every pixel that contributes to the template may be matched against every pixel of the image using any means of comparison (eg. SAD, SSD, cross-correlation), or it can me Feature based, where the matching is on the basis of some strong features that the template ma ....etc

ABSTRACT
This paper deals with the basics of iris, its properties and how it adds some advantageous features to recognize the correct person. In this paper we discuss the details regarding the information about how the iris is located, to distinguish it from other parts of the eye, how the scanner scans the whole pattern of the iris while enrolling and matching and how the scanned patterns are converted into 256 bytes of data so that it can be stored in the database. We compare the iris codes of th ....etc
