– kernel inotify monitor can be restricted to a configurable user html root
– kernel inotify monitor with dynamic sysctl limits for optimal performance
– kernel inotify alerting through daily and/or optional weekly reports
– e-mail alert reporting after every scan execution (manual & daily)
– path, extension and signature based ignore options
– background scanner option for unattended scan operations
– verbose logging & output of all actions
LMD ini juga dapat melakukan monitoring secara realtime dengan contoh perintah di terminal seperti dibawah ini :
# maldet --monitor users
# maldet --monitor /root/monitor_paths
# maldet --monitor /home/mike,/home/ashton
Mau scan secara manual juga bisa dengan perintah :
