This type of intrusion detection system is abbreviated to HIDS and it mainly operates by investigating facts in admin data files on the pc that it safeguards. People information consist of log data files and config data files.
When we classify the design from the NIDS according to the method interactivity home, There are 2 sorts: on-line and off-line NIDS, normally referred to as inline and tap mode, respectively.
