Why should I add a firewall to my server solution?
A firewall is an essential addition for many servers - it protects the data in a private network from external users that should not be granted access to this data. A firewall proxy server seeks to act as an intermediary between two end systems and add an extra level of security on top of these. There are various screening methods available for those with a firewall added to their server; from blocking certain IPs to allowing remote access using either a username/password or a secure VPN based system. On a basic level, a software firewall will allow you to block unused ports on your server, ensuring disallowed port access does not occur.
