Host intrusion protection software, or HIPS, provides rule and behavior-based system monitoring to guard against unwanted changes. HIPS can be used alongside traditional antivirus software to add an extra layer of security. Some host intrusion protection software provides a learning mode and pre-configured rules, but in general HIPS is best suited for more advanced computer users.
首先说一下，HIPS软件的说法感觉并不正式，因为在HIPS是基于主机的入侵保护系统的简称（所以注意请不要混淆）

sandbox&影子系统
In computer security, a sandbox is a security mechanism for separating running programs. It is often used to execute untested code, or untrusted programs from unverified third-parties, suppliers, untrusted users and untrusted websites.[1]
The sandbox typically provides a tightly controlled set of resources for guest programs to run in, such as scratch space on disk and memory. Network access, the ability to inspect the host system or read from input devices are usually disallowed or heavily restricted. In this sense, sandboxes are a specific example ofvirtualization.
沙盒（英语：Sandbox）是：为一些来源不可信、具备破坏力或无法判定程序意图的程序，提供试验环境。然而，沙盒中的所有改动对操作系统不会造成任何损失。通常，这种技术被计算机技术人员广泛使用，尤其是计算机杀毒软件行业，沙盒是一个观察计算机病毒的重要环境。影子系统即是利用了这种技术的软件之一。
