Security security

Application Security starts during the development phase. ÃÛ¶¹ÊÓƵ recommends to apply the following security best practices.

Use Request Session use-request-session

Following the principle of least privilege, ÃÛ¶¹ÊÓƵ recommends that every repository access is done by using the session bound to the user request and proper access control.

Protect against Cross-Site Scripting (XSS) protect-against-cross-site-scripting-xss

Cross-site scripting (XSS) allows attackers to inject code into web pages viewed by other users. This security vulnerability can be exploited by malicious web users to bypass access controls.

AEM applies the principle of filtering all user-supplied content upon output. Preventing XSS is given the highest priority during both development and testing.

The XSS protection mechanism provided by AEM is based on the provided by . The default AntiSamy configuration can be found at

/libs/cq/xssprotection/config.xml

It is important that you adapt this configuration to your own security needs by overlaying the configuration file. The official will provide you with all the information you need in order to implement your security requirements.

Additionally, a web application firewall, such as , can provide reliable, central control over the security of the deployment environment and protect against previously undetected cross-site scripting attacks.

Access to Cloud Service Information access-to-cloud-service-information

When you integrate your AEM instance with the ÃÛ¶¹ÊÓƵ Marketing Cloud you use Cloud Service configurations. Information about these configurations, together with any statistics collected are stored in the repository. We recommend that, if you are using this functionality, you review whether the default security on this information matches your requirements.

The webservicesupport module writes statistics and configuration information under:

/etc/cloudservices

With the default permissions:

Protect against Cross-Site Request Forgery Attacks protect-against-cross-site-request-forgery-attacks
