    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).
