What a Firewall is, how it works. Firewall type

It may be vulnerable to computer-related computers (generally on a computer network) and hacking attacks. The way in which the method is used is to search for a connected machine (randomly send block blocks), then "furo" for security purposes.

Essa ameaça é ainda maior se or a computer connected to the internet. The reason for this is that various objects and their objects PC connected to a regular control or not silent or broadly connected or it is an IP address. To save us from criminals, we fear at least one great fire.

What is a Firewall?
A firewall (also called "firewall"), is a system that allows to protect a computer or a network of computers from intrusions that come from a third network (specifically from the Internet). The firewall is a system that allows filtering the data packets that go around the network. It is a "narrow bridge" that filters, at least, the traffic between the internal and external network.

A firewall can be a program (software) or a computer (hardware) that acts as an intermediary between the local network (or the local computer) and one or several external networks.

How does a Firewall work?
A firewall works as a barrier between the internet or other public networks and our computer. Any type of traffic that is not on the list allowed by the firewall does not enter or leave the computer.

To do this, a firewall system contains a set of predefined rules that allow:

Authorize a connection (Allow)
Block a connection (Deny)
Redirect a connection request without notifying the sender (Drop).
The set of these rules allows to install a filtering method dependent on the security policy adopted by the organization. There are usually two types of security policies that allow:

Allow only explicitly authorized communications: "Everything that is not explicitly authorized is prohibited".
Prevent any communication that was explicitly prohibited.
The first method is the safest, but requires a precise definition of the communication needs of the entire network.

Type of firewall
Basically, there are two types of firewalls for different data types and network sizes.

Software Firewalls (free or paid apps)
Hardware firewall (that is, using devices)
Software firewall
Free Firewall is software that can be freely deployed and used on the computer. They are also called "Desktop Firewall" or "Firewall Software".

They are a small home and office-based firewall to monitor and block Internet traffic when needed. An on-board firewall is installed on almost any computer.

The features of the software platform are:

Loans are included in the operating system, and most for personal use
You can easily access other security products
The tool is not required to install the computer
It's easy to insert, it's usually activated, and operating system systems do not look like a scanner that works.
Computer screens are the most important security that needs to be installed on the computer, and there is no reason to point out the use of one desktop desktop.
The business path that works on the road is a default failure, but most safeguards and controls are based on its configuration and performance.
Firewall Hardware
Usually the toolbar is installed on the drivers we use to access the Internet, which means that all the computers will be stored after the rotor by the thread inserted into the tool. Most of the coming drivers are coming in with the attachments installed.

The configuration of the toolbar is a tool that is more difficult than the installation of computer screens, and most often used by a browser that is accessing the Internet. It should be noted that the difference between the router between the router and the roller without the slightest strap, so it is good to sell the fabric and care.
Instructions for using firewalls in Windows 7, Windows 8, and Windows 10
One of the best ways to avoid foreign offenses is to use a good firewall when there is no limit on the Internet.

Although the market has absolutely complete and advanced alternatives, in fact, the most advanced version of the version will be in a good state like Mozilla Firewall, and we will always stay alive. For more information about network chat settings and third-party applications, please feel free to.



One of the best features we can count on is the ability to create different capabilities, help us safely work with us, and help all the options and needs center the more effective the center. Usage is regular and fully available.

In addition, it is possible to define ports or specific IP addresses or to determine how to manage future IPS protocols.

First stage

To access all Windows FATELITE options, go to the Start menu and click Control Panel.

Step 2

We are part of the "system and security" that you click on on "SharePoint".



Step 3

On screen we can enable or activate the content in accordance with our network-specific classification.

It should be borne in mind that Windows Flash Player provides coverage for three different networks:

Domain network
Common network
Home or business network (private network).
The network type and security options are selected when they are connected.

It is important to set up separate alternatives for any network and to determine if Flash Player is activated. Limit checklists or close all future interactions.



One of the most beautiful features of the Windows Firewall can be provided by more than one professor, that is, if our PC is connected to a car network and will allow the public network manager to control the coming future controls and the future network.

Additionally, the more effective task is to create new management rules for any network from the Fibers section on the control panel.

Step four

If we had to click on the required ports to open, by the way we started, we would need to click on the "new rule" button and appear in the window
