A plan is an integral part of Internet security in one place. Its job is to eliminate hackers, viruses and worms that use the Internet to attack your computer with malicious code. Malicious code can destroy files and cause malfunctions. Sometimes a firewall can help prevent other people from stealing your current personal information.

You communicate with the Internet through ports that allow you to send and output information. And therein lies the threat, says Mike Nadelman, a technology guru who works for a San Francisco computer repair company that designs and implements computer networks and troubleshoots computer problems for businesses and individuals.

“It’s like a house. You’ve seen a lot of windows and tables and ways to bring things in and out of the house,” predicts Nadelman. – Window; some people leave them wide. Firewalls basically block certain windows and doors and allow others to create them, with an emphasis on filtering in.One and the output words that connect them.”

   How the software works.
   A firewall, which can be software or hardware, controls the content that passes between your computer and the Internet. It filters out, or possibly packs, bits of information sent over the Internet, only letting through material that the computer is allowed to transmit or receive. It also prevents unauthorized connections from your computer to other previous computers, and the firewall can hide your computer’s unique IP address, making it “invisible” to other users on the Internet in general.

2. How do I know if my company has a firewall?
   Today, most Windows communities have a firewall installed. To find out if your firewall is disabled, click the START menu, then click Control Panel. Click on the security center (look at the multi-colored shield). When the firewall is enabled, youYou see one green indicator. If you’re using Windows XP, security guru Franny Dubin, author of The Little Black Book for Computer Security (29^th Street Press), notes that the policy doesn’t block outgoing traffic. This is important given the trend towards bots, where outsiders gain access to your computer and therefore use it for spamming and other nefarious purposes.

To check if your Mac’s firewall is enabled, go to Finder > Applications > System Preferences. In the System Preferences window that appears, click the Share icon, Dubin says. You can open the firewall software button and configure the firewall settings.

   A software firewall is hosted on a single computer. This requires little additional hardware or cabling, but still consumes computing resources.rs. Other firewall classes are available in hardware configurations. Hardware A router is a true multi-port box that allows multiple computers to connect to the Internet, but it requires a cable. Wireless modems are a type of equipment that allows multiple kitchen appliances such as computers and personal desktop assistants (PDAs) to be connected to the Internet wirelessly. When setting up a wireless network, you must make sure that you buy a real wireless router with a built-in firewall.

“I’d say you want a (software) firewall tied to your computer,” Dubin says. You can find free software firewalls, but Nadelman advises caution. looking for solutions will download fake stuff,” he warns. Do not click on pop-ups and/or emails offering free firewalls and other security-related programs. Beware of fake programs with names similar to these.standing products.

1. Prepare to communicate with this firewall.
   Some firewalls ask you about the traffic between your computer and the Internet. A pop-up window may ask if you want to block or allow the current contact, or only allow this contact. Pop-ups will be removed when the program adds your instructions to the firewall rules.

2. One ​​firewall is not enough for a dog.
   You still need virus protection, anti-spyware, and email and download application protection. Look for protections that include firewalls, anti-virus and anti-spyware features, and especially programs that only offer the latest firewall version, for example.

It’s important to know before doing this so that your computer’s protection is ready, confirms Nadelman. “Do your research before customers download anything that appears on your screen. It’s important to do your research before you and your family turn on your computer.”
