I am using a nulled version of ministra portal from Sla...X, which I am not sure if it has a backdoor or not (given the history of Sla..X it is almost certain that my portal has a backdoor). So far I have no clue of a back door in my portal. But I have taken some precautions, that I want to share with you.
Purpose of this
1. Use the latest nginx because ministra portal comes with old nginx)
2. Prevent EASY access to your admin panel (if anyone knows your password or if anyone knows the backdoor)
3. Apply rate limiting to your portal (you can add this by referring to nginx documentation)
Prerequisites:
1. Basic knowledge of UFW
2. Basic knowledge of conf files in nginx.
3. Ability to search in google for any error that may come up. Because I am sharing my config file, it is custom made for my needs. Your configuration may be different than mine, so you may need some tweaking to the configuration.
