If you process credit cards on a website, your site needs to be in compliance with the Payment Card Industry Data Security Standard. (This is abbreviated as PCI DSS, and even more often referred to simply as PCI.) PCI compliance certifies that your organization takes all necessary steps to protect sensitive customer data and provides a set of standards for your infrastructure and server setup. While Liquid Web does not offer full PCI compliance certification, we do offer a separate service that scans your server to see that PCI DSS requirements are met, a great tool during the compliance process.

In a vast majority of cases, Linux does a fantastic job of automatically scheduling processes. The more urgent processes are given a higher priority, and the less urgent processes a lower priority. In rare circumstances, the scheduler might not prioritize processes as you would like. For example, backup processes could be taking up resources that you would rather be used serving web pages. If you would like to regain a bit control over process priorities, the nice and renice commands will give you some.

If you have ever set up a Storm server in the past, you have probably seen how much easier it is to get a new server up and running than a traditional server. Once the server itself is up, of course, there is still plenty of work to do getting other pieces configured: installing an application, setting up specific database configurations, and so forth. Tools such as Puppet and Chef help you to automate this process… but you still have to log in to your manage account and order new servers to begin with.

At least, you did. With the Storm API, you can automate nearly all aspects of administering your Storm servers.

High Performance Block Storage (HPBS) provides additional hard drive space for your Storm Server with just a few clicks. The space is not pre-formatted; rather, it is a raw block device. The simplicity of providing a raw block device on the cloud means that you can mount and format the space on your server however you would like, with whatever filesystem is appropriate for your needs. This does entail a small amount of work getting the space into a usable state.

One component of Liquid Web’s Server Secure service is an Apache module called Mod Security (often shortened to just “modsec”). Modsec monitors all incoming HTTP requests for malicious behavior, and does not complete requests that meet certain criteria. These criteria are spelled out in what are called “rules” or “rulesets”.

In an ideal world, only malicious requests would be caught in modsec’s trap. Unfortunately, there are some instances where legitimate requests are stopped as well. How do we determine that this is what happening, and what can we do about it?
