Accessibility is the magic word for todays blog. If you’re lucky enough to run a website, then the whole world has access to it by default!
Now lets imagine that the website you’re running is targeted for a geographically specific customer base such as the USA. You get up one morning and decide to take a look at your web analytic reports, and find that Japan is where the second largest volume of traffic is coming from.

However, with our renewed focus on web application security, I thought this would be a good example to show how easy virtual patching is with the industry standard tools used in the Loadbalancer.org appliance.Continue reading...
Denial of Service (DOS) attacks can be especially effective against certain types of web application. If the application is highly dynamic or database intensive it can be remarkably simple to degrade or cripple the functionality of a site. This blog article describes some simple methods to mitigate single source IP DOS attacks using HAProxy. I've described how you would implement the techniques using the Loadbalancer.org appliance but they are easily transferable to any HAProxy based cluster.Continue reading...
