The information about the latest internet attacks and the need for firewall was very useful but the things need to know before installing firewall and which one is best is present in the following text.
An ideal firewall works like a well oiled machine, closing open ports and monitoring network traffic unobtrusively. All the millions of users who are the victims of computer crimes need to protect themselves against it. A firewall monitors communication between devices on a network, and prevents unauthorized access from other sources. It is not enough if the computer user knows about the firewall and its application, the user has to go for the best firewall. If the user doesn’t choose the best one then it is same as having no firewall.
There are few security rules which should be done before installing firewall in your computer.
Deploy updates:
The most important security measure is that always keep windows up to date. If you do not install the security updates then hackers can easily enter into your system through the unplugged leaks. If this is the case then no firewalls or antivirus can help you.
Delete unnecessary services:
Fewer services running in the background can reduce the vulnerabilities for hackers to exploit. So found the programs running at the back and close it.
Check for open ports:
It is also possible to find which ports are open for hackers to attack by taking a test. This can be done by entering net stat-ano in command prompt.
Install anti virus programs:
The firewall is not alone sufficient for all round protection. In addition to it an anti virus program is needed to guard the computer from malware and attacks through external storage devices.
A firewall has more to do than just guard the doorway into the pc. There are some operating systems which provide their own firewall while installing it but those firewalls could not withstand the attacks from latest malwares or spywares. Ultimately a firewall monitors incoming and outgoing network traffic. So it is wise to adopt best firewalls like comodo firewall program that it doesn’t have any loop holes for the attackers. This comodo firewall is a free version and you download it from their website.
