Host-based IDS (HIDS) or host-based IPS (HIPS) are specialized software that "link" with the host operating system to perform access control and threat prevention functions.The HIDS or HIPS are specialized software that "links" with the host operating system to perform access control and threat prevention functions. In most cases, this software allows the host NIC to perform network detection and protection functions. In addition, HIDS and HIPS can enable end-hosts to enforce security policies, as well as compliance and audit controls. Typically, the HIDS or HIPS will allow itself to be sandwiched between the application and operating system kernel functions, monitoring the application's calls to the kernel, which is the basic function of the software. The HIDS or HIPS will employ most of the traffic analysis methods used by the NIDS/NIPS mentioned earlier, such as anomaly-based analysis and heuristic-based analysis. HIDS and HIPS can check file integrity, monitor registries, analyze logs, and detect malware. The main advantage of HIDS over NIDS is that it can view all traffic to and from a particular host, determine whether an attack has been successful, and issue alert messages. HIDS is able to detect attacks that evade NIDS detection by encryption or by packet fragmentation. The disadvantage of a HIDS or HIPS is that it can only detect traffic to and from a specific host or attacks launched against that host, and has no knowledge of any events occurring in the network. However, many commercial products offer management control platforms that allow the HIDS or HIPS to be "linked" to a network-based intrusion system to compensate for this drawback. In addition, once a host has a HIDS or HIPS installed, it not only consumes more CPU resources, but also increases packet processing latency. Most security architectures use both network-based and host-based IDS or IPS solutions.Table 4-10 shows the differences between a network-based IDS or IPS solution and a host-based IDS or IPS solution. Chapter 10 takes a closer look at the technologies associated with implementing HIDS and HIPS./-...
