I. Overview
- The internet can be divided into three layers:
- Surface Web
- Deep Web
- Dark Web
- The terms "Deep Web" and "Dark Web" are often confused but have distinct meanings.
- Definition: Content freely available and accessible to anyone.
- Examples: Public blogs, news sites, public social media posts (e.g., public Twitter posts).
- Indexing: Indexed by search engines (Google, Bing, etc.).
- Accessibility: Can be found using standard search engines.
- Definition: Web content that cannot be accessed without logging in or specific credentials.
- Accessibility: Requires a password or login to access.
- Examples:
- Checking your bank balance online.
- Reading your email through a web service (Gmail, Yahoo, etc.).
- Logging into social media accounts (Facebook, Instagram, etc.).
- Viewing personal shopping history on e-commerce sites (Amazon, etc.).
- Indexing: Not indexed by search engines; therefore, not publicly available.
- Reason for Non-Indexing: To protect sensitive, private user data.
- Definition: Web content that requires specialized software to access.
- Accessibility: Cannot be accessed with a standard web browser.
- Key Technology: Tor (The Onion Router) is the most prevalent technology.
- Tor Functionality:
- Enables anonymous access to the web.
- Uses a system of encryption and relays.
- Hides the user's IP address, preventing ISPs from monitoring browsing activity.
- Prevents visited sites from knowing the visitor's IP address.
- Onion Services: Websites accessible only through Tor, and are part of the Dark Web. They also hide their IP addresses.
- Anonymity: Both users and websites can remain anonymous.
- Use Cases:
- Criminal Activity: Anonymity can be exploited for illegal purposes.
- Legitimate Purposes:
- Whistleblowing
- Political discussion
- Caution: Exercise caution when accessing content on the dark web.
