Both firewalls and intrusion detection and prevention systems are used extensively in network security‚ including protecting the network perimeter. They will be configured based on where they are located and the security requirements within that security zone. Write a 3-4 page paper in which you: 1. Describe the different types of firewalls. 2. Analyze how the security requirements within different security zones will impact the firewall configurations. 3. Describe the purpose of a intrusion

CHAPTER-1 INTRODUCTION 1.1 Firewall in computer networks Firewall: A set of related programs‚ located at a network gateway server‚ which protects the resources of a private network from users from other networks using security policies. The Internet has made large amounts of information available to the average computer user at home‚ in business and in education. For many people‚ having access to this information is no longer just an advantage‚ it is essential. Yet connecting a private

Chapter 6 Questions 1. What is the typical relationship among the untrusted network‚ the firewall‚ and the trusted network? The relationship is that data is only limited to what firewalls allow via specific places called “ports”. There is the untrusted network on the outside‚ then the firewall which prevents unwanted or suspicious connections‚ and the trusted network is what lies within the bounds of the firewall. 2. What is the relationship between a TCP and UDP packet? Will any specific transaction

Introduction to Firewalls - Traditionally‚ a firewall is defined as any device (or software) used to filter or control the flow of traffic. Firewalls are typically implemented on the network perimeter‚ and function by defining trusted and untrusted zones Most firewalls will permit traffic from the trusted zone to the untrusted zone‚ without any explicit configuration. However‚ traffic from the untrusted zone to the trusted zone must be explicitly permitted. Thus‚ any traffic that is

A firewall is a device or software running on a device that inspects network traffic and allows or blocks traffic based on a set of rules. * A network-based firewall inspects traffic as it flows between networks. For example‚ you can install a network-based firewall on the edge of your private network that connects to the Internet to protect against attacks from Internet hosts. * A host-based firewall inspects traffic received by a host. Use a host-based firewall to protect against attacks

Firewalls There are three main types of firewalls that are used in the networking community. The three types are Network-level‚ Circuit-Level Gateway‚ and Application-Level. Network-level Fire walls work at the network level. It inspects packet headers and filter traffic based on their source and destination. According to "Pc Results Inc." (2013)‚ "They also take into account IP addresses‚ ports used and services requested.” Circuit-level Gateway firewalls work by determining the legitimacy of
