Getting started with sitecore: The 101-guide to the community

A few years back, back in the Sitecore 7.x days, I started to work with Sitecore. I originated from the SharePoint community (take note of the capital “P”!), where there are SO many active bloggers. I think this was caused by a bit of the history. “Back in the SharePoint 2007 days” all the SharePoint info we got, came from google, or from reflector, as the documentation wasn’t always “that well written”. It appeared that there were a few persons actively blogging about their findings and through the years, the amount of people actively blogging, writing cool code or helping each other out, exploded, but you had (and still have) to find your ways to find all the information.

I see the same pattern happening in Sitecore. A lot of great functionality, a great product, but not every feature is always documented. As everyone tries to get the most out of the platform, people are seeking the boundaries of the product and finding out how stuff works. A lot of people are looking for help, a lot of people are blogging, but it’s not always that evident to find the sources that you need. “Where is the community?” you might ask. And that’s exactly why I decided to write this blogpost.

A first free lesson: First lesson: SiteCore is written as Sitecore. Please take 
care of this, as most Sitecore community members are a bit sensitive to it ;).

Sitecore Security #4: Serve your site securely over https with Let’s Encrypt

In a previous blogpost about the Http Strict Transport Security I explained how to force connections to make use of https to encrypt connections. A lot of people think it’s expensive, hard to implement and slow. This blogpost shows off how you can get a free, secure certificate, get your Sitecore site up-and-running in no more than 5 minutes, just by using the Let’s Encrypt service. Source-code can be found here on Github.

Sitecore Security #3: Prevent XSS using Content Security Policy

Clientside code is being used more and more on modern websites. Any kind of resources, for example Javascript, css, fonts, complete pages can be loaded dynamically into websites, from the current website or from an external domain. Attackers might be able to pull off an XSS attack by loading different kinds of data or scripts into your site which will run on your client’s browsers. These injections might happen on your own site, or in external services that you make use of (for example, disquss, or ads you are displaying). Applying a content security policy is one of the defenses against this kind of attack. This blogpost shows of scenarios that might happen (some of them tailored to Sitecore) and how the content security policy can help to prevent a successful attack from happening. As regular solutions provided on the internet do not supply the flexibility that a Sitecore solution (and CMS’ses in general) needs I decided to create a content manageable module and added that one to my SitecoreSecurity module.

This is not a write-up on the complete CSP specification, there are other great sources for that on the web, I included them at the end of the article.

The module will be available on the marketplace when it has passed quality control.
Sourcecode is available on:
