Abstract
The world is surging towards a digital revolution where computer networks mediate every aspect of modern life. Not many years ago, most computers were carefully guarded mainframes, held tightly in the hands of skilled professionals. The systems and their guardians combined to provide ironclad protection of the organization’s all important data. Today the world is scary, anyone can get their hands on to the personal computers and even link into networks.
Today the threat to the information on the network has grown to the greatest extent. Information is the most vital aspect of every organization. Access to the internet can open the world to communicating with customers and vendors, and is an immense source of information. But the same opportunities can open your Local Area Network to possible attacks by thieves and vandals. These attackers and hackers try to harm a system and disrupt information exploiting vulnerabilities by using various techniques, methods, and tools. Many analysts say very bluntly, if you are on the Internet, you need a firewall.
This paper discusses the risks you face when you connect to the Internet, describes the types of attacks that can occur, and offers an overview of firewall technology, which can protect your network from hackers. Specifically, the paper discusses the implementation of a firewall and what you should consider in choosing the type of firewall you require.
