What does a firewall do?

• Blocks access to certain ports, making them unavailable to hackers scanning the network for a vulnerable service running on those ports.
• Filters both inbound and outbound traffic. This allows you to limit communication to and from particular location(s).
• Examines all traffic routed between two networks to see if it meets certain criteria. If it does, the traffic is routed through.
• Can help mitigate or lessen the effect of a DOS attack.
• Can help manage public access to private networked resources such as host applications, databases, shares, etc.
• Can be used to log all hostile or suspicious attempts to enter the network.
• Address filtering – filters packets based on their source and destination IP addresses and port numbers.
• Protocol filtering – filters specific types of network traffic based on the protocol used, for example HTTP, FTP or DNS.
• Can filter traffic by packet attribute or state.

You should consider a firewall if:

• You are running e-commerce applications.
• You are hosting sensitive data on the server.
• Examines all traffic routed between two networks to see if it meets certain criteria. If it does, the traffic is routed through.
• Your server has been previously compromised.
• You need to limit access to data or applications on the server.
• You would like to set up a Virtual Private Network (VPN).
