Adjusting HSTS settings for public wifi's

Solved Security
  • Hariundefined

    Hello there! Yesterday, I visited IKEA and connected to public Wi-Fi. Google and other websites worked as expected, but when I tried to access my own website, it didn’t load for some reason. I received an HSTS error and had to switch to mobile data to access my site.

    I understand we can’t just turn off HSTS since we already said browsers that we will use HSTS for next 12 months

    I’ve been using these cloudflare settings for the past two years. If there are any adjustments that need to be made to ensure my site functions in public Wi-Fi areas, please let me know.

    @Hari You already have the correct settings here. It’s more likely to be an issue with the Wi-Fi configuration at Ikea than an issue with CF or your own site. You can test this from another public Wi-Fi access point to either prove or disprove this theory.

    I would certainly not make any changes without validating this as I’ve mentioned above. If it does prove problematic from a completely different connection source, then fair enough, it needs review.

    @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.

    @DownPW it’s your only realistic option at this stage.

    @Hari DDoS protection is not just a switch, or one component. It’s a collection of different and often disparate technologies that when grouped together form the basis of a combined toolset that can be used in defence.

    Typically these consist of IDS (Instrusion Detection System) and IPS (Intrusion Prevention System) components that detect irregularities in network traffic, and will take decisive action based on predefined rulesets, or in the case of more modern systems, AI and ML.

    Traditional “traffic shaping” technology is also deployed, so if an attack cannot be easily identified as malicious, the bandwidth available to that connection is severely limited to nothing more than a trickle rather than a full flow.

    Years ago, ISP’s used traffic shaping (also called “policers”) as an effective means of stopping applications such as BearShare, eDonkey, Napster, and other P2P based sharing systems from functioning correctly - essentially reducing the “appeal” of distributing and seeding illegal downloads. This was essentially the ISP’s way of saying “stop what you are doing please” without actually pulling the plug.

    These days, DDoS attacks are designed to overwhelm - not assume control of - webservers and other public facing components. It’s rare for small entities to be attacked unless there is some form of political agenda driven by your site or product. A classic example is governmental institutions or lawmakers who effectively are classed as “enforcers” and those who disagree are effectively making a statement in the form of Denial of Service.

    DDoS protection is effectively the responsibility of the hosting provider, but you shouldn’t just assume that they will protect you or your site. Their responsibility stops at their infrastructure, so it’s then up to you too decide how you full the gap in between your host and the website.

    Typically, you’d leverage something like Imunify360 which you can get for Plesk (and something I’d strongly recommend) but it’s not free, and is a paid (not expensive per month) subscription. If you want to use VirtualMin then there are a variety of tools readily available out of the box such as firewalls and fail2ban.

    @justoverclock Not necessarily. You only need to use this if it fails from the Virtualmin window

    @hari the cache level for woocommerce should always be bypass. Any caching of woocommerce will cause you serious issues and will result in the checkout process not functioning correctly.

    This does mean that the overall experience will be slower (depending on geographic location) although CF is known to cause significant issues hence the need to bypass.

    If you want to cache as much as possible, then set rules to bypass caching on the cart and account pages etc.
