Host Intrusion Prevention System (HIPS) aims to stop malware by monitoring the behavior of code. HIPS is an installed software package which monitors a single host for suspicious activity by analyzing events occurring within that host. This makes it possible to help keep your system secure without depending on a specific threat to be added to a detection update. But,if you cant recognize something by its looks, you might be able to categorize it by its behavior. This is where methods like HIPS come into play.”]
