    @DownPW This won’t be the first time that Amazon and others like them are being bought to account. I recall seeing a documentary on the TV recently where they sent in a reporter with secret cameras to film the strict regimen and constant threat of being fired for not meeting targets that workers are placed under.

    The surveillance just takes this to a whole new level in my view and it’s like being placed under a microscope for constant scrutiny. This goes well beyond the surveillance placed on prisoners!

    @DownPW 🙂 most of this really depends on your desired security model. In all cases with firewalls, less is always more, although it’s never as clear cut as that, and there are always bespoke ports you’ll need to open periodically.

    Heztner’s DDoS protection is superior, and I know they have invested a lot of time, effort, and money into making it extremely effective. However, if you consider that the largest ever DDoS attack hit Cloudflare at 71m rps (and they were able to deflect it), and each attack can last anywhere between 8-24 hours which really depends on how determined the attacker(s) is/are, you can never be fully prepared - nor can you trace it’s true origin.

    DDoS attacks by their nature (Distributed Denial of Service) are conducted by large numbers of devices whom have become part of a “bot army” - and in most cases, the owners of these devices are blissfully unaware that they have been attacked and are under command and control from a nefarious resource. Given that the attacks originate from multiple sources, this allows the real attacker to observe from a distance whilst concealing their own identity and origin in the process.

    If you consider the desired effect of DDoS, it is not an attempt to access ports that are typically closed, but to flood (and eventually overwhelm) the target (such as a website) with millions of requests per second in an attempt to force it offline. Victims of DDoS attacks are often financial services for example, with either extortion or financial gain being the primary objective - in other words, pay for the originator to stop the attack.

    It’s even possible to get DDoS as a service these days - with a credit card, a few clicks of a mouse and a target IP, you can have your own proxy campaign running in minutes which typically involves “booters” or “stressers” - see below for more

    @DownPW said in Setting for high load and prevent DDoS (sysctl, iptables, crowdsec or other):

    in short if you have any advice to give to secure the best.

    It’s not just about DDos or firewalls. There are a number of vulnerabilities on all systems that if not patched, will expose that same system to exploit. One of my favourite online testers which does a lot more than most basic ones is below

    I’d start with the findings reported here and use that to branch outwards.

    @phenomlab
    Sorry to delay in responding, yes as i mentioned above, i had to remove my redis from docker and reinstall a new image with this command

    docker run --name=redis -p 127.0.0.1:6379:6379 -d -t redis:alpine

    and now when i test my ip and port on
    https://www.yougetsignal.com/tools/open-ports/

    the status of my redis port is closed. I think which to configure firewall in droplet digital ocean is a good idea too, and i will configure soon.
    Thanks for the help!

    No they have a free and pro console instance.
    We can see alert with IP, Source AS, scenario attack etc…

    Installation on the NODEBB server without problems. Very good tools

    We can also do research on IPs via the crowdsec analyzer

    I believe it’s 500 per month in the Free version
