Best Security Improvement

[levely]

I'm starting a new forum which will be quite controversial and I'm sure it will be a target for hackers. What mods or combination of mods do you recommend for 2.0.9?

Keeping your forum up-to-date nothing more is needed.

Keeping your server up to date would also be a good idea. Also, there are a few mods out there like forum firewall and a few anti-spam mods that can be installed that may just help. Search the mod site and I am sure you will find a few that may offer you the edge you are looking for.

The most vulnerable item is the server, keep that secure and up to date and you'll be safe for the biggest part.
It's also good practice to keep SMF up to date, though most vulnerabilities are exploited with the servers.

Also, keep your administrators educated. The weakest link is the user. If you have a week password or one that you use in multiple sites, you're more likely to be hacked.

also making sure your files are not writable will help. if you have a shared server/hosting and another site gets hacked if your files are not writable then your forum has a lesser chance of getting hacked.
