NETWORK SECURITY

Abstract:

A ``network'' has been defined as ``any set of interlinking lines resembling a net, a network of roads || an interconnected system, a network of alliances.'' A computer network is simply a system of interconnected computers.Networking is to share programs, but granting others to access a computer device reveals an open window for those with foul motives.Network security is the effort to create a secure computing platform.We are focusing on a tool firewall for network security.We have also discussed some types of protocols.Firewalls is a non-flammable wall that helps prevent dangerous viruses and hackers.A firewall makes the connection secure between a trusted and an untrusted network. Firewalls can come in the form of hardware or software.Firewall Software is a basic requirement for anyone using broadband to prevent hacking, virus, and other security risks. Firewall software is software designed to prevent unauthorized access to a computer or network that is connected to the Internet. Firewall software comes in a variety of forms, offering a wide variety of features, protection capabilities, scalability and cost.there are different types of firewalls in market.

Introduction to Networking:

A basic understanding of computer networks is requisite in order to understand the principles of network security. In this section, we'll cover some of the foundations of computer networking and security, then move on to security measures Once we've covered this, we'll go back and discuss some of the threats that managers and administrators of computer networks need to confront, and then some measures that can be used to reduce the exposure to the risks of network computing

What is a Network?:

A ``network'' has been defined as ``any set of interlinking lines resembling a net, a network of roads || an interconnected system, a network of alliances.''This
definition suits our purpose well: a computer network is simply a system of interconnected computers.
