    now some things you need to think about: - cloud init - this will need to be secure so lock it down hard anything not needed an alternative OS to look at if you have the ability's is https://www.alpinelinux.org/ also as these devices are not that powerfull every extra agent / abstaction layer you add impacts performance need to look at low over head security https://www.crowdsec.net/ and https://github.com/fail2ban/fail2ban (if you call fail2ban security) - using certificates to authenticate ssh login

  • Firewall rules beyond "deny incoming, enable only the ports that you need"
    2 projects | /r/linuxadmin | 21 Apr 2023
    https://github.com/fail2ban/fail2ban is a mature, easy to set up way to have some dynamic firewall rules that respond to attacks. There are more sophisticated options, but they are probably not worth the return on time investment for you.

  • Configuring Fail2ban for Traefik Reverse Proxy
    3 projects | /r/selfhosted | 22 Jan 2023
    I've played a bit with Traefik as reverse proxy and wanted to implement fail2ban for it, after switching from Nginx Proxy Manager. It finally works and successfully bans threat actors that conduct malicous HTTP requests. As soon as a multitude of HTTP errors are detected by fail2ban in Traefik's JSON access logs, the attacker's IP address is banned. I am using a dockerized fail2ban container and ban locally via iptables as well as optionally on Cloudflare, using Cloudflare's API. A ban notification via Telegram can also be configured.

    However I do not merely rely on this trust. I monitor my systems aggressively. I implement additional security measures to mitigate my exposure and liability. There are systems like fail2ban and login-shield that I use as additional layers (and have audited the code - these systems are a lot simpler than Linux - it's unrealistic for anybody to actually fully-audit the Linux kernel).

    You need to setup reverse proxy. nginx-proxy-manager, swag. There are also more options like caddy, haproxy etc... You can also setup a VPN and or a service like authelia, fail2ban, crowdsec to restrict access to your site.

  • Ok, I've migrated email to selfhosted

    spamassassin or rspamd or ASSP. All very good. Spamassassin just works, but you need to feed it a good cohort of spam and ham (about 1000 messages each). Most people only send it the spam which will then bias it quite a bit and not have it classify spam as spam unless it's the worst of the bunch. Spamassassin is a filter for your mail server. rspamd is the same idea. ASSP is highly configurable and a proxy.
  • Why Your Emails May Be Bouncing Back & What You Can Do About It
    3 projects | dev.to | 6 May 2021
    To detect whether incoming emails are malicious, mail servers also use spam scanners, such as Apache's popular SpamAssasin. The internal workings of these spam scanners can be somewhat complicated (involving Naive Bayes Classifiers on trained, large datasets, for the curious), but the primary takeaway is that these classification systems typically assign a numerical point value to an incoming email to determine the validity of the message. The higher the score, the more likely that the email is spam. For reference, the ISP Optimum states the following regarding their spam filtering:
