Other recommandations

Upgrade PrestaShop to the latest version to disable multiquery executions (separated by “;”)
Change the default database prefix ps_ by a new longer arbitrary prefix. Nethertheless, be warned that this is useless against blackhat with DBA senior skill because of a design vulnerability in DBMS
Activate OWASP 942’s rules on your WAF (Web application firewall), be warned that you will probably break your backoffice and you will need to pre-configure some bypasses against these set of rules.
