Threats in cyberspace are getting increasingly sophisticated. Antivirus software and firewalls are no longer effective as businesses depend on them to protect themselves. After an attacker gets in through perimeter defenses, they can silently get around within a system.<\/p>\n\n\n\n

That is where a Host-Based Intrusion Detection System (HIDS) is necessary.<\/p>\n\n\n\n

A HIDS is used to track activity on a single device, e.g., a server, workstation, or cloud instance. It does not monitor network traffic, but instead it monitors system-level actions. It mainly includes file modifications, attempts to log in, changes to system configurations, and suspicious processes.<\/p>\n\n\n\n

In this ultimate guide, we will discuss the mechanism of HIDS, its important features, advantages, steps of implementation, best practice and limitations in simple and understandable terms.<\/p>\n\n\n\n

A Host-Based Intrusion Detection System (HIDS) is a cybersecurity solution<\/a> installed directly on a specific device (host). That host could be:<\/p>\n\n\n\n
