解説
問 87
Incorrectア
RSS is an XML-based format and mechanism for distributing update information (headlines, summaries, URLs, etc.) from news sites and blogs, which anyone can subscribe to in order to receive publicly available information. It has nothing to do with anonymity or non-searchable content, so it is wrong.
Incorrectイ
SEO (Search Engine Optimization) refers to the techniques and methods used to make one’s own site rank higher in search results. It is in fact a measure to get a site found by search engines — the exact opposite of the non-searchable, anonymous content described in the question — so it is wrong.
Incorrectウ
Cross-Site Scripting (XSS) is the name of an attack technique that exploits a website vulnerability to inject malicious scripts and run them in the user’s browser. It is an attack method, not a general term for Internet content, so it is wrong.
- エ
正解 The correct answer is エ, “Dark web.” The dark web is a general term for highly anonymous Internet content that is not indexed by the crawlers of ordinary search engines and can only be accessed using special software such as Tor. Because its origin and connection path are hard to trace, it is sometimes misused for preparing cyberattacks or as a venue for the underground trading of illegal goods, drugs, and the like. All of the features listed in the question — “not found by search engines,” “high anonymity,” “used for cyberattacks and illegal trading,” and “special software required” — match, so エ is correct.
ここがポイント
- Dark web = a body of highly anonymous content that can be accessed only with dedicated software such as Tor and is not indexed by ordinary search engines; it is easily misused for illegal trading and cyberattacks.
- RSS (a format for distributing update information), SEO (a measure for ranking higher in search), and XSS (an attack technique) are all terms from different categories and should not be confused with the dark web.
