Hey,
I have read several times that firewall is an important parameter from the security point of view.
So, what is firewall?
Is it required for my website?
A firewall is software used to maintain the security of a private network. Firewalls block unauthorized access to or from private networks and are often employed to prevent unauthorized Web users or illicit software from gaining access to private networks connected to the Internet. A firewall may be implemented using hardware, software, or a combination of both.
A firewall is recognized as the first line of defense in securing sensitive information. For better safety, the data can be encrypted.
Types of the firewall are as follows:-
- Packet filtering firewalls.
- Circuit-level gateways.
- Stateful inspection firewalls.
- Application-level gateways.
- Next-gen firewalls.
Personally, I would recommend you for security reasons you need to install a firewall for your website.
