Secure ownCloud


In what ways can I make sure my ownCloud setup is secure? I installed fail2ban so you can not bruteforce the login credentials. Any other ways I can test if my ownCloud setup is secure?


There are several apps in the marketplace for security hardenings like second-factor providers, native brute-force protection or password policy, check it out:

Also, just follow server updates, all supported versions are getting all the security fixes immediately.


Hi! Alright, is there anything I need to do secure it once you have logged in? Can any logged in user execute system commands?

Of course he can not. Also, ownCloud is working with apache user rights. It can not hurt your system.
