• Mass Scanning

  Can I get banned for mass scanning with https://github.com/robertdavidgraham/masscan or does it slow down any other vms from other persons? Source: 11 months ago

• Has anyone ever had their homelab or network hacked? What happened?

  Nope, this doesn't work any more. Shodan checks all ports (so any attackers using data from Shodan already know which ports you have open), and tools like masscan (https://github.com/robertdavidgraham/masscan) let you portscan the entire IPv4 address space in less than 10 minutes.

• Private server intruded

  The discord user at the time used the tool "Masscan" to scan every 25565 port on the internet, he claims he was able to get the entire internet scanned in just a few minutes with a 512MB buyvm slice. Source: about 1 year ago

• My home server is frustrating me. Please help me, home server wizards.

  Changing the default port does nothing for security. It only prevents some basic brute force or default password scripts. Anyone is able to scan for it in no time anyway (https://github.com/robertdavidgraham/masscan). Source: about 1 year ago

• Should I be Concerned?

  But it should blow away the far-too-common belief that no-one's after you because you're not interesting enough. IPv4 is smaller than we think. It is not difficult to scan the entire ipv4 space in minutes. And every single one of those is going to knock your door on the way past. Source: about 1 year ago

• Did you have serious attacks on your exposed services before?

  This tool crowdsec.net is really interesting to mitigate and enact defense systems for different scenarios. Source: about 1 year ago

• What service can I use to ban users?

  You should check out https://crowdsec.net. More advanced, uses crowdsources cti to block attacks even before they happen. Also both nginx and captcha is supported.

• A 'leech-like' connection constantly established on my server

  Before falling too much in love with Fail2Ban try taking a look at https://crowdsec.net. Similar functionality but way more advanced (but easier to configure). New project that leverages the power of the crowd and shares information of attacks among users so they help each other out protecting themselves. Source: over 1 year ago

• Banning users for certain actions

  You could try out https://crowdsec.net. It’s an advanced FOSS framework for detecting a number of different attacks and not limited to just brute force attacks like Fail2Ban as /u/nonself suggests. The basic concept of CrowdSes is that it reads log, detects attacks, mitigates attacks (CrowdSec integrates directly into the Flask application) and shares information about those attacks with everyone else using...

• Block traffic from every country except the USA? - Apache2/SSH

  Not what you suggested but have you considered https://crowdsec.net? Not just a collaborative and more advanced version of Fail2Ban but in this case you want it because of the collaborative blocklist; we made an article showing that 92% of attacks was blocked in advanced by ip reputation before any attacks were performed. Disclaimer: I am head of community so I might be a bit biased. It’s still a cool FOSS project... Source: over 1 year ago
