Module 3: Protecting Your Data and Privacy

Protecting Your Devices and Network

• Activate a firewall (software or hardware) to safeguard against unauthorized access; it must be regularly updated.
• Employ antivirus and antispyware software to prevent malicious software (viruses and spyware) from compromising device security.
• Regularly manage operating system and browser settings; keep them updated to protect against vulnerabilities.
• Utilize password protection on all devices, ensuring sensitive data is encrypted to deter unauthorized access.
• Store minimal sensitive information on mobile devices to limit exposure in case of theft or loss.

Wireless Network Security at Home

• Change the default SSID and password of your wireless router to enhance security against potential intruders.
• Enable WPA2 encryption on your wireless router to secure wireless communications, although recent vulnerabilities (like KRACK attacks) may still pose risks.
• Keep all wireless devices updated immediately when security updates are released to minimize vulnerabilities.
• Opt for a wired connection for devices with a Network Interface Card (NIC) when possible for enhanced security.
• Use trusted VPN services to secure connections on wireless networks, adding a layer of protection against eavesdropping.

Public Wi-Fi Risks

• Avoid accessing personal information or sending sensitive data over public Wi-Fi due to inherent risks.
• Ensure that file and media sharing settings are disabled and that user authentication with encryption is required on your device.
• Utilize encrypted VPN services to secure data transmissions while using public networks; even intercepted data remains undeciphered due to encryption.

Strong Passwords

• Consider using passphrases instead of traditional passwords for better memorability and security; aim for longer structures that are less susceptible to attacks.
• Follow current guidelines by the National Institute of Standards and Technology (NIST), advocating for passwords between 8 to 64 characters and discouraging easily guessed combinations.

Who Owns Your Data?

• Prior to signing up for online services, read the Terms of Service to understand your rights, including access to data, usage restrictions, and actions upon account closure.
• Clarity on how your data will be used by service providers is crucial for informed consent.

Safeguarding Your Online Privacy

• Use two-factor authentication for added security; it requires a second piece of information, enhancing identity verification.
• Open Authorization (OAuth) allows access to third-party applications without sharing passwords, simplifying login processes via existing credentials from trusted sites.

Email and Web Browser Privacy

• Activate private browsing modes in browsers (e.g., InPrivate in Internet Explorer, Incognito in Chrome) to minimize tracking by disabling cookies and clearing browsing history.
• Understand that even private browsing does not guarantee complete anonymity, as companies may still track user behavior through other means.

Discover Your Own Risky Online Behavior

• Regular self-assessment of online habits is essential to identify and correct risky behaviors that could compromise data security.

Summary of Key Concepts

• It's vital to secure devices by turning on firewalls, installing protective software, and maintaining updated systems.
• Secure home networks by changing default settings and utilizing appropriate encryption.
• Public Wi-Fi should be navigated cautiously, with proactive measures in place to protect personal data.
