Network security is a significant aspect when managing network. There are issues that should be put in place in order to have security over a network. One of the significant components that are of great use is firewalls. Firewalls provide a great tool that network administrators use to secure their networks. We have had a chance to look at computer networks and the use of VPN in the security aspects of the networks. We have had to go in-depth on how the networks relate to security.

One of the most significant aspects of a firewall is the installation and implementation process. Firewalls should be ...

The principle purpose of a firewall is to intelligently bar unrequested connections that intend to get into the network. For instance, a user’s laptop connected to an organizations domain can access shared files and folders on the network. However, if the laptop does not have the domain configurations, the firewall bars any incoming connections to the organization’s network from the laptop. Such a feature for the firewall helps to safeguard the network from potential malicious incoming traffic.

Windows Firewall plus other third-party firewalls perform the same principle function of barring unauthorized incoming connections. Third-party firewalls, in the course of their ...

Introduction

The basic pillars on which any organization stands are the information security management policies adopted by the organizations and their levels. The system may be built on chaos if the basic parameters of security are not clearly defined. Medium-sized organizations are a major part of global economic activity but the normal information security standards are not feasible for these organizations since they are mainly developed for large organizations. This results in a growing risk for sensitive data security breaches. Thus, there is significant need to combat these security threats. Some of the problems related to security and their solutions are given ...

A firewall is responsible for controlling access among devices such as computers, networks and servers. Firewalls are deployed between the safe zone and the unsafe zones such as the internet. Firewalls acts as filters for network traffic. Network connections traverse the firewall and unauthorized packets are stopped. The filtering mechanism is based on IP addresses and ports.

Originally, firewalls was designed a gateway to deny or access network resources. Firewalls can also inspect the contents of the data packets to filter other packets, block packets that contain offensive information and block intrusion attempts.

Firewall can be configured to monitor different ...

For any computer device machine deprived of a firewall, then a personal or company computer has its operating open to attacks and this is considered risky. In recent occurrences, hacked computers have been subject to the passwords cracking, credit card numbers stealing, bank account information fraud, and virtually any sensitive information on stored on the computer becomes accessible to malicious computer hackers. In this case scenario hackers can get in, take what they want, and even leave an opening port they can frequently use to access the information over and over again without the owners noticing.
