If you have Dedicated Servers then security and protection is the most important thing which should be considered. Basically firewall refers to application or device which allow or deny traffic or any incoming or outgoing connections based upon set of rules. Generally it works within a one single network or over various networks in large operations. Firewall prevents any network threats. It’s architecture is to block any vulnerable threats to the main Dedicated server. On a Linux server, we can also configure IPtables or CSF firewall through cPanel.

Firewall basically filters packets or units of data transfers basically TCP and UDP traffic. Cisco are known for their firewall appliances which of course compete with other appliances such as Juniper. Some of the Linux firewall include Cisco ASA, Coyote Linux etc. Windows Operating Systems offer in-built Firewall, famously known as Windows Firewall. However, we can also configure hardware firewall such as Cisco etc.

Security is a very important concept today and it definitely needs implementation on every dedicated server so before choosing any hosting you should check the type of server protections they provide.
