How does a VPN work?

A VPN creates a secure connection between your device and a server that acts as a gateway to the internet. This means your internet traffic is routed through the VPN server, making it more difficult for unauthorized individuals to access your data.

Study Notes

WiFi Security and Safe Browsing

  • This section covers how to safely use WiFi networks, VPNs, web exploits, safe browsing, and cookies.
  • WiFi is a wireless internet connection, but like any internet connection, it has unique threats.
  • Risks include using unsecured WiFi connections, public WiFi, untrusted hotspots ("Evil Twins"), and weak WiFi passwords.
  • Risk factors: Every user with correct login details can connect, making the network vulnerable to eavesdropping. Intruders can intercept sensitive data (passwords, emails). Hackers can install malware infecting connected computers.

Public WiFi

  • Public WiFi networks are especially dangerous.
  • Unsecured connections don't require passwords or encrypt the data transmitted.
  • Although many public WiFi networks now require passwords and encryption, some remain unsecured.

False Hotspots

  • Hotspots are physical locations for internet access (often using WiFi).
  • Hackers can set up fake hotspots to look legitimate (e.g., "free WiFi"). This allows them to access unencrypted data sent through the fake network.

The Evil Twin

  • This attack involves a hacker creating a hotspot that mimics an existing, legitimate WiFi network.
  • By mimicking a legitimate network, the hacker can trick users into connecting to their network instead.
  • Once connected, the hacker can intercept information and credentials, and possibly install malicious software on the victim's device.

Protecting the WiFi Network

  • Protect WiFi networks with strong passwords.
  • Avoid entering sensitive information (passwords, credit card details) on unsecured websites.
  • Avoid default router settings; change them regularly.
  • Don't share passwords.
  • Use HTTPS protocols for secure communications. HTTPS ensures communications are encrypted.

VPNs

  • VPN stands for Virtual Private Network.
  • It's a useful and common method of securing online information.
  • VPNs operate within other networks like the internet, typically encrypted.
  • Remote users can encrypt data sent across shared or public networks, as if directly connected to a private network.

Why Use a VPN?

  • Keeps information safe by using strong encryption that only the user and VPN users can decrypt.
  • Maintains connection privacy by routing data through private VPN servers instead of directly through the internet.
  • Conceals IP address, masking the user's location.
  • Bypasses geographical restrictions (accessing content blocked in a region).

Web Exploits

  • Web browsers are common attack vectors. Browser attacks can be categorized:
    • User-targeted attacks
    • Web application-targeted attacks
    • Browser-targeted attacks
  • Techniques like phishing can trick users into downloading malicious files disguised as legitimate downloads.
  • Cross-Site Scripting (XSS): Allows hackers to inject malicious code into web applications. Users may unknowingly access and execute this code when interacting with the site—potentially causing harm to their system.

Cross-Site Request Forgery (CSRF)

  • Forces users to execute unwanted actions on a web app (e.g., money transfer).
  • Attackers plant malicious scripts in legitimate websites and links.
  • Exploits the fact that a user is already logged in on the target website.

Safe Browsing

  • Use HTTPS to ensure secure website connections; it's a big step towards securing information online.
  • Use cookies safely: customize browser cookie settings for security.
    • If cookies aren't harmful, one can set long expiration timers for personal access details and browsing history.
    • If sharing a computer with others, clear private browsing data each time to prevent access to cookies.

Advanced Tools

  • Google Safe Browsing: blacklists malicious URLs.
  • My WOT: checks website reputations.
  • Adblock: Prevents displayed ads; some websites will require disabling the extension to display their content).
