Ok, i made this guide for people that keeping Crying like:
"My Server got h4x3d!!!!111!!!elevenone1!!11@11!1". Its Common Sence, but this can still be usefull...
Tip 1: Never give Grant Premissions to any SQL account, Give premission to a few, selected Tables/Databases.This can save your server many times =)
Tip 2: Never set "From Host:" Info (at User Manager ^_^) to "%" (All IPs). ALWAYS from a specific IP!
Tip 3: Backup Everything ! So in case someone hacks into your server you can give every player their Items/Characters/Accounts in 5-10 mins of Importing Tables
Tip 4: Dont set "weak" passwords for users! Example:
User: (Friends Log in Name here!)
From Host: (Friend's IP)
Password: 1
Passwords like "1" or "Friends Name" are easy to hack. I prefer using many, MANY Numbers in a row (Like Glider Keys)
Example: 09054249a4
Thats all i had to say , good luck protecting your Server!
