Hardware Firewall

Hardware firewalls are an essential layer of security for your server. Server Intellect offers a hardware firewall to ensure your dedicated server is protected against various types of attacks. The safest and most effective type of firewall is a hardware firewall.

Each server firewall rule set is fully managed through our portal on a real time basis with the ability to bypass at any time. Firewalls can be added at anytime without the need to re-IP the server and can be activated instantly. Monthly server bandwidth is recorded at the server switch port, preventing traffic blocked by the firewall from counting against your monthly allotments. This, in turn, reduces your costs and the need to pay for blocked, undesired traffic.

What is a firewall?

A firewall protects networked computers from intentional hostile intrusion that could compromise confidentiality or result in data corruption or denial of service. It may be a hardware device or a software program running on a secure host computer. In either case, it must have at least two network interfaces, one for the network it is intended to protect, and one for the network it is exposed to. A firewall sits at the junction point or gateway between the two networks, usually a private network and a public network such as the Internet.

What does a firewall do?

A firewall examines all traffic routed between the two networks to see if it meets certain criteria. If it does, it is routed between the networks, otherwise it is stopped. A firewall filters both inbound and outbound traffic. It can also manage public access to private networked resources such as host applications. It can be used to log all attempts to enter the private network and trigger alarms when hostile or unauthorized entry is attempted. Firewalls can filter packets based on their source and destination addresses and port numbers. This is known as address filtering. Firewalls can also filter specific types of network traffic. This is also known as protocol filtering because the decision to forward or reject traffic is dependant upon the protocol used, for example HTTP, ftp or telnet. Firewalls can also filter traffic by packet attribute or state.

What is a hardware firewall?

A Hardware Firewall is a network device that is connected upstream from a server. The Firewall blocks unwanted traffic from a server before the traffic ever reaches the server. The main advantage to having a Hardware Firewall is that a server only has to handle 'good' traffic and no resources are wasted dealing with the 'bad' traffic.
