Firewalls or firewalls are a tool created when the rise of the Internet began around the world, around the 80s. Generally when hackers find that through these networks they can access the personal information of other users.
It is considered one of the first existing security measures for computers, which it can be installed via hardware or software.
To avoid violations of user privacy, several developers have been tasked with forming this barrier that filters the digital content that is transmitted over the computer network.
If you want to know in depth how this tool works and how it is configured, continue reading this article to get it.
Firewall or firewall, the first security barrier of a computer
Firewalls are devices responsible for the traffic management and filtering of applications in in and out of the network that connects two or more computers.
Its principle consists of a series of rules or criteria that determine whether access can be sent or received, while other authorized accesses are performed inside the computer. These rules can be thought of as those set by default by software or hardware, or they can be configured for the use and convenience of your equipment.
Likewise, they may vary and be updated over time in order to keep up to date as well protect yourself from the new types of attacks that are transmitted on the Internet.
As far as security is concerned, this tool cannot eliminate any malware that tries to enter your computer. Rather, it will just look for a way to block your voice. For this reason, it is recommended that the safety of the equipment is not limited solely to this barrier. Rather, it is combined with other types of software designed for OS.
How do firewalls or firewalls work?
It is generally found at the junction of two networks or computers and is responsible for protection of the information transmitted through the router. Either by authorizing or blocking traffic. Automatically configure a filter intended for identify different types of long-term data.
As mentioned at the beginning, this security barrier can be classified as either hardware or software. Depending on the type of application that is on your computer.
Un physical firewall it is what comes in the products or router that is responsible for generating the connection network of your computer. These guys are recommended for corporate networks, as the firewall is located between the Internet access and the connection switch. This way every computer connected to this network will be protected.
On the other hand, firewall as a program is recommended for home networks, protecting only the equipment that installed it. There are currently several types of online servers such as iWeb. Which are responsible for acting as a firewall or firewall directly inside the browser.
An example of this is WatchGuard. A company that offers this type of service by creating and deploying a hardware-type firewall available for home and corporate networks.
Do you want to configure your firewall? It's very simple!
In the same way it was described in the previous point. The configurations of a firewall or firewall will be updated as new types of malicious data are generated. However, these defense parameters can be managed manually through operating system settings.
Among the changes that can be made is the possibility of restrict access to several servers on a network. In case they are considered suspicious. Likewise, you can change the digital packet filter, determine the number of connections made across a network, among other things.
In short, the defense of information traffic transmitted from your computer is ensured by this simple (but wonderful) accessory that is here to stay.
