RKhunter

RKHunter (Rootkit Hunter) on Ubuntu is a repackaged open-source security scanning and monitoring solution with optional maintenance support by ATH, wherein additional charges apply for support. RKHunter is designed to help system administrators, DevOps teams, security professionals, and IT operations teams identify potential security threats on Linux systems, including known rootkits, backdoors, suspicious files, hidden files, unexpected system modifications, and other indicators that may require further investigation. It provides command-line based security checks that can be incorporated into routine Linux server security and auditing workflows.

RKHunter performs a range of system checks, including rootkit and backdoor detection, suspicious binary and file checks, hidden file and directory detection, system configuration checks, and other security-oriented assessments. It can be used for on-demand or scheduled security scans and generates reports that administrators can review when investigating potential security issues. The tool can be deployed on Ubuntu-based AWS EC2 environments and integrated with existing Linux administration, monitoring, logging, and automation workflows. Key benefits include lightweight security scanning, automated checks, command-line operation, configurable scanning workflows, security auditing support, and compatibility with Linux server environments.
