Computers are used for almost everything nowadays. With the use of computers and the internet comes the need for proper security. A firewall is a system used to stop unauthorized access to intranets and other private networks. Firewalls can either be in hardware or software form.
In simplest terms, firewalls work by filtering all messages and blocking those that do not meet specified criteria in order to prevent hackers from obtaining personal information or other data.
Importance of Firewalls
The internet can be an unsafe place with hackers trying to steal people’s personal information. There are many ways security can be breached; IP spoofing, man-in-the-middle attacks, and network packet sniffers are but a few problems.
A good firewall can offer protection from hackers trying to access personal information or trying to attack a computer; they are a solid defense system that should be used along with other security measures such as virus protection.
There are several different types of firewalls. Each type uses a different method of protecting private networks. Some firewalls are more secure than others. In order to completely understand what a firewall is, it’s crucial to understand the different types of firewalls that are available.
Packet Filtering Firewalls
This type of firewall inspects all the packets that pass through the network. If any packet does not meet certain criteria, the firewall will reject it. Users can define what types of packets are acceptable and what type should be rejected.
Packet filtering firewalls are effective but can be complicated and take time to configure. This type of firewall is very secure, but it does have a weakness. Packet filtering firewalls are susceptible to things like IP spoofing.
Packet filtering firewalls are convenient because they are located in many different devices. Routers, wireless access points, and switches are but a few devices that can use this firewall.
This type of firewall works by acting on behalf of the user. Proxy servers protect users by hiding their network address. Proxy firewalls open requested webpages for the client, and then they allow the client to view the page. These firewalls do everything for the client such as connecting to servers.
Proxy firewalls have the ability to deny certain information that the user does not want. Any potentially harmful or dangerous sites can be analyzed by the proxy server and rejected, protecting the user and their data.
Circuit-Level Gateway Firewalls
These firewalls work at the session layer of the OSI model. They establish a secure UDP or TCP connection; afterwards, there is no further inspection done. Circuit-level gateways are very fast and efficient when compared to other types of firewalls, but their security measures are not as thorough.
This type of firewall employs several other types of firewalls together including packet filtering and even gateways. These generally do not use proxy firewalls to keep the system from working too slowly, but they are very effective and have the benefits of every type of firewall they use.
The internet is an essential tool for businesses and individuals in today’s technological world. In order to safely use the internet and private networks, firewalls need to be used to protect a user’s personal information.
