Our Premium version of the Ubuntu Server Hardening Script is the ultimate solution for securing your server. This script is intended to be run on a fresh box and will provide a quick start to securing your new server. The script includes several important security features that will help protect your server from potential attacks and breaches.
The script first updates and upgrades all packages on the server to ensure that all of the software is up-to-date and secure. Next, it installs and configures ufw firewall, which is a simple and easy-to-use firewall for Ubuntu. This firewall will help to block unwanted incoming traffic and protect your server from potential attacks.
The script also installs and configures fail2ban, which is a tool that helps to protect your server from brute-force attacks. This tool monitors your server’s log files and automatically bans IP addresses that are attempting to brute-force their way into your server.
Additionally, the script assists with the creation of a new user and adding it to the sudo group. This allows you to have a non-root user with elevated privileges, which is generally considered more secure than using the root user account.
The script also secures SSH by disabling password authentication and root login, and configures ClamAV, an open-source antivirus software, to help you detect and prevent malware on your server.
In addition to the above, the Premium version includes the following advanced security features:
- Google Authenticator setup: This adds an additional layer of security by requiring users to provide a time-based one-time password (TOTP) in addition to their username and password.
- Logwatch monitoring: This tool monitors your server’s log files and sends you daily reports of any suspicious activity.
- Kernel hardening: This improves the security of your server’s kernel by implementing several security-related sysctl settings.
- File and directory integrity monitoring using Tripwire: This tool monitors your server’s file system for any changes and alerts you of any unauthorized modifications.
It’s important to note that we do not provide any warranties or guarantees about security. The user is ultimately responsible for the security of the server and we are not liable for any attacks or issues that may occur as a result of using our script.
