How to Configure CSP header in AEM ? Content Security Policy (CSP) is a security feature that helps prevent cross-site scripting (XSS) and other code injection attacks by restricting the sources from which a page can load resources. To implement a CSP header in an Apache web server, you can use the Header directive in your Apache configuration. Here are the steps to implement a CSP header in Apache: Determine your CSP policy: First, you need to determine your CSP policy. This policy defines the rules for what types of content can be loaded from which sources. You can use a CSP policy generator like the one available on the Mozilla Developer Network (MDN) website to generate a policy that meets your needs. Add the CSP header to your Apache configuration: Once you have your CSP policy, you can add the CSP header to your Apache configuration.

Adobe Experience Manager offers an integration with the Amazon S3 storage solution, allowing binary data for images, documents and videos to be stored in an S3 bucket. Amazon S3 is highly performant and offers nearly infinite storage capacity.   When talking about terabyte storage, performance is everything. The choices made during the planning and architecting phase can literally make or break the performance of a CMS system and the websites running on it.  Adobe Experience Manager offers a number of storage methods, each offering a different way of storing data. Each of these options has its strengths and weaknesses. In AEM storage the mechanisms are called Micro Kernels, or MK for short.  In this article we will look at the AEM with S3 data store.
