Top 8 Host-Based Intrusion Detection System Tools

    Top 8 Host-Based Intrusion Detection System Tools

    Host-Based Intrusion Detection Systems are applications that secure the computer from malicious activities. It analyzes incoming traffic and creates logs about malware, viruses, or other subversive activities.

    Networks have opened up plenty of opportunities for businesses and the more these networks are utilized, the more there is a threat of intrusion in the business. Hence, IDS tools came into the picture to resolve such issues and benefit businesses in using the networks.

    HIDS gives visibility into the crucial state of a computer system. It monitors the behavior and sends out alerts when unusual activity occurs.

    This will cover the top tools in the host-based intrusion detection systems.
