The mythical Wall of Fire : “How could this have happened, I am behind a firewall?<\/em><\/strong>”<\/p>\n

A firewall<\/a> is often assumed to be some kind of magic bullet.<\/p>\n

This short article covers the essence of what a firewall is – and more importantly what it is not.<\/p>\n

The word Firewall<\/a> is borrowed from another application. A noun describing the barrier between the engine and the crew compartment through which controls pass, and fire, cannot [fayuh r-wawl<\/em>]. As such we will find them on boats, ships, planes… as well as where we tend to apply the word these days – computing.<\/p>\n

Dwelling more on the controls than the fire part there – allowing control or use through a barrier.<\/p>\n

Without veering off on an adventure covering protocols, ports, and networking – lets just say that we can allow web and email traffic in and out from the entire world, and access to the controls, the back office, administration to only a given set of locations.<\/p>\n

As such if bad things happen, and they come in over services exposed to the public – such as mail or web – then the firewall has done it’s job…. even if bad things have occurred. “But I thought we were behind a firewall<\/em>” – you probably were… however it is not a panacea, it is part of a solution. #JustSaying<\/em><\/p>\n

So I guess that asks the question what can I do to further secure myself?<\/p>\n

In terms of restricting access, and help control what is passing in and out of your site there are plenty of other tools you can bring to the party – either in the form of vendor supplied appliances, or services that filter content upstream.<\/p>\n

Web Application Firewalls (WAF<\/a>);<\/strong><\/p>\n

Distributed Denial of Service (DDoS<\/a>) mitigation;<\/strong><\/p>\n

Content Delivery Network (CDN<\/a>);<\/strong><\/p>\n

IDS\/IPS<\/a> (Intrusion Detection\/Prevention System);<\/strong><\/p>\n

… all something very much for another article.However all of these are part of a layered approach we can provide on request, or simply advise upon.<\/p>\n

If you have concerns over your shared hosting, virtual machine, dedicated services, or transit – do not hesitate to contact sales or technical to talk about your needs, architecture, security both physical network \/ service related… we will be only to glad to advise and assist.<\/p>\n","protected":false},"excerpt":{"rendered":"
