TYPO3 website security is an imperative these days and ignoring it is quite costly in terms of time, money and resources. However, with TYPO3, many of the most common security checks are easily done with a single TYPO3 extension.

Security Check, found as security_check in the TYPO3 extension repository, runs from the TYPO3 backend and checks about 40 of the most common TYPO3 security concerns. Besides a report of potential lapses and guidance on how to fix them, there are a couple of tools for finding unnecessary and insecure files.

When TYPO3’s Security Check is combined with the principles and steps outlined in the TYPO3 Security Cookbook, downloadable below, a TYPO3 website’s security is quite solid from the server-side.
