Windows 101: Lesson 13 - Security

In this lesson, we’ll go over some fundamental tips for keeping your computer and information safe, based on the tools and features we’ve covered so far. While our work computers are set up to be mostly secure, that doesn’t mean they can’t be attacked. By following a few simple guidelines, you can reduce the risk of potential threats. These tips aren’t just for work—they’re also important to follow on your personal devices to protect your own information.

1. Keeping Your Browser Secure (Google Chrome)

Since you’ll be using Google Chrome to browse the Internet, it’s important to ensure your browser stays secure.

• Only visit trusted websites: Stick to well-known websites, especially when entering personal information. Be cautious of unfamiliar links and ads, especially ones offering deals that seem too good to be true.
• Look for the "Not Secure" warning: Chrome no longer shows "http" or "https" in the address bar, but it does display a "Not Secure" warning on the left side of the URL for sites that don’t use encryption. Avoid entering any sensitive information on these sites.

• Keep Chrome updated: Chrome regularly releases updates that include security improvements. When an update is available, the hamburger menu (three dots) will turn into an Update button. Click it to update Chrome. Always keep your browser updated to protect against new threats.

2. Strong Passwords for Accounts (Browser and Settings)

Using strong passwords is key to protecting your online accounts, and it’s important to use different passwords for every website. This way, if one password is compromised, your other accounts remain safe.

• Why use different passwords?: If you use the same password everywhere and one account gets hacked, attackers can try the same password on other sites. Different passwords help limit the damage if one account is compromised.
• Writing down your passwords: Always write down your passwords and store them in a secure place, like a notebook kept in a locked drawer. This ensures you don’t forget them while keeping them safe from others.

Latest Recommendations for Strong Passwords:

• Use at least 12 characters.
• Include a mix of uppercase and lowercase letters, numbers, and special characters (like @, $, or %).
• Avoid using easily guessed information like birthdays, common words, or keyboard patterns (like “1234” or “password”).

Chrome also has a built-in password manager that securely saves and manages your passwords. You can enable this in Settings > Autofill > Passwords.

3. Securing Your Files and Folders (File Explorer)

Your files and folders contain important information, so it’s crucial to keep them secure.

• Be careful when downloading files: Only download files from trusted websites. Malicious files can harm your computer, so always verify the source before downloading anything.

• Back up important files: Regularly back up your important files to an external drive or cloud storage to avoid data loss.

4. Keeping Your Software Updated (Windows and Chrome)

Keeping both your browser and your Windows operating system updated is one of the easiest ways to protect your computer.

• Windows updates: You don’t have to manually update Windows, as it will automatically download updates. However, when you see that updates are waiting, it’s important to reboot your computer as soon as your shift is over. This ensures your system is protected with the latest security patches.

• Chrome updates: As mentioned earlier, Chrome frequently updates its security features. Keep Chrome updated whenever you see the Update button in the top-right corner.

5. Safe Browsing Practices

It’s important to keep your work computer secure by avoiding personal use, as visiting certain websites can expose the system to malicious software.

• Avoid using the computer for personal activities: Visiting gaming sites, movie streaming sites, or piracy websites can install malicious software that could harm the computer and compromise our company's security.
• Don’t log in to personal accounts: Never log into personal accounts (like email or social media) on the work computer. Personal accounts can have vulnerabilities, such as receiving malicious emails, which could infect the company’s systems.

By following these tips, you can keep your browsing activity, files, and computer secure while using Windows and Google Chrome. These practices are important not just for your work devices, but also for protecting your personal devices and accounts. In the next lesson, we’ll explore more about safe Internet practices and staying protected online.
