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).
