**课程名称：** 道德黑客：深度网络与暗网入门指南 **课程概述：** 本课程深入探讨了互联网的“深度网络”（Deep Web）和“暗网”（Dark Net）。深度网络是指那些无法通过常规搜索引擎（如Google、Bing、Yahoo）完全访问的互联网部分。其内容广泛，包括未被搜索引擎索引的页面、付费访问网站、私人数据库以及暗网。 大多数搜索引擎通过“爬虫”（bots）来抓取网络内容并将其添加到索引中。尽管深度网络的具体规模未知，但专家估计搜索引擎仅抓取并索引了互联网可访问内容不到1%。可被搜索到的网络内容被称为“表面网络”（Surface Web）。 深度网络中的大部分内容是合法且非犯罪性的，例如电子邮件、聊天记录、社交媒体的私密内容、电子银行对账单、电子健康记录（EHR）等。此外，任何需要付费订阅的网站，如新闻文章或付费教育内容网站，以及Netflix等付费服务网站，也因为需要付费验证而不会被爬虫检索。 本课程将一步步指导您学习和理解深度网络与暗网，包括如何访问和导航它们。让我们一同踏上探索深度网络和暗网的学习之旅。
The deep web is an umbrella term for parts of the internet not fully accessible using standard search engines such as Google, Bing and Yahoo. The contents of the deep web range from pages that were not indexed by search engines, paywalled sites, private databases and the dark web.Every search engine uses bots to crawl the web and add the new content they find to the search engine's index. It isn't known how large the deep web is, but many experts estimate that search engines crawl and index less than 1% of all the content that can be accessed over the internet. The searchable content of the web is referred to as the surface web.Much of the content of the deep web is legitimate and noncriminal in nature. Deep web content includes email messages, chat messages, private content on social media sites, electronic bank statements, electronic health records (EHR) and other content that is accessible one way or another over the internet.Any website that is paywalled, such as the text of news articles or educational content site that requires a subscription, is also blocked from search engine bots. Fee-for-service sites like Netflix are also not crawled by the bots.In this comprehensive course you will learn and understand about deep web and dark net. How to access it and how to navigate. We will guide you step by step. Let's begin the journey of learning about deep web and dark net together.
