  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

    Question Safe to enable postgrey with free Plesk Email Security (Amavis + SpamAssassin + ClamAV)?

    Hi everyone, I'm running a Plesk server using the free Plesk Email Security extension, which includes Amavis and SpamAssassin. I’ve also installed ClamAV manually, and it's working perfectly within the current mail pipeline. To further reduce spam and bot traffic, I now plan to add Greylisting...

    Question Modsecurity - Apache or Nginx

    I’m planning to make a third attempt next week to install ModSecurity under Plesk. During the setup, there’s an option to choose whether ModSecurity should be applied to Nginx or Apache. Since I’m using Nginx as a reverse proxy in front of Apache, it’s unclear which option I should select.

    Issue How to properly configure Fail2Ban for ModSecurity in Plesk with NGINX?

    Unfortunately, not yet. The first time I tried it, it worked for a short time, but then ModSecurity stopped logging, and after uninstalling it, NGINX also stopped working, so I had to run my websites on Apache for a while. The second time I tried it, a month ago, it worked better, and...

    Question Massive Brute-Force Attacks on Plesk Panel – Looking for Additional Protection Measures

    I have now blocked CN, RU, ID, PH, KR, TH, VN, MY, IN . This has helped. Recently, however, I've also noticed a sharp increase in attacks on my server from the US. I hope I can continue to manage this with fail2ban so I don't have to add US to the list.

    Question Massive Brute-Force Attacks on Plesk Panel – Looking for Additional Protection Measures

    I also changed port 22, which helps against targeted 22 attacks but not against port scans looking for SSH access. I also blocked SSH access using a user/password combination. You can only log in to my server with keys!

    Question Massive Brute-Force Attacks on Plesk Panel – Looking for Additional Protection Measures

    Thanks for your good recommendation from Danami Juggernaut. But at the moment, it seems to be taking too much time for me to get it working. I'm about to go on a long trip and can only work on this solution more intensively after I return. In the meantime, I'm blocking all countries from which...

    Question Massive Brute-Force Attacks on Plesk Panel – Looking for Additional Protection Measures

    Thank you for all your valuable advice! Fail2Ban has now banned 1600 IPs and as I blocked countries with the most attackers now the attacks are slowing down to two to four each hour. I will test danami, as @learning_curve recommended. I am not sure, whether I could follow the recommendation by...

    Question Massive Brute-Force Attacks on Plesk Panel – Looking for Additional Protection Measures

    Hello everyone, I’m running a Plesk panel that has been under a massive brute-force attack for some time. The login attempts are happening non-stop from globally distributed IPs, targeting users like admin, root, and even custom usernames. I have already implemented the following security...

    Issue How to properly configure Fail2Ban for ModSecurity in Plesk with NGINX?

    Thank you for your quick response! Unfortunately, Fail2Ban didn’t work because it couldn’t find any IPs in the ModSecurity audit log files, and ModSecurity itself stopped logging unexpectedly. As a result, I had to remove it again. Additionally, switching from the selected Apache rule set (2.9)...

    Issue How to properly configure Fail2Ban for ModSecurity in Plesk with NGINX?

    Hello everyone, I have successfully installed ModSecurity with NGINX on my Plesk server. Now, I want to use Fail2Ban to permanently block IPs of attackers that ModSecurity identifies. However, after installation, I noticed that the configuration files for ModSecurity were missing in Fail2Ban...

    Issue Modsecurity works with Apache but error with nginx

    I repaired it now by myself. To help others here is a step-by-step-approach: 1. ls -alh /etc/nginx/modsecurity.d/rules/owasp_modsecurity_crs_4-plesk/ => No rules have been installed. 2. nginx -V 2>&1 | grep -o with-http_modsecurity_module => no module installed also available 3...
