Jailing unwanted bots with Fail2Ban and custom filters
One challenge of hosting a website online 24 hours a day 7 days a week, 365 days a year, is keeping it secure.
I have been hosting websites for over 20 years now. One thing I have noticed, is the more successful your site is, the more attention you are likely to receive from others with nefarious intents. In fact I would even go so far as to say there is a correlation between genuine website visitors and nefarious ones.
