Serious Discussion A Habit-Based Guide to Internet Security

[Divergent]

No software, no matter how advanced, can replace good habits. Your behavior is the single most powerful factor in your online security. This guide focuses on the critical habits that will build your personal defense, with a special emphasis on the dangers of unofficial downloads and the importance of backups.

1. Practice Smart Password Management​

Your passwords are the keys to your digital life. Weak or reused passwords make you an easy target.

• Use Unique Passwords for Every Account: If a hacker steals your password from one site, they won't be able to access your other accounts.
• Create Strong, Complex Passwords: A good password is long (12-15+ characters) and includes a mix of uppercase and lowercase letters, numbers, and symbols.
• Use a Password Manager: These tools securely store all your unique, complex passwords, so you only need to remember one master password.
• Enable Two-Factor Authentication (2FA) Everywhere: This adds a crucial second layer of security by requiring a code from your phone or another device.

2. Be Skeptical of Links and Downloads​

This is where the majority of infections begin. A moment of caution can save you from a major security headache.

• Hover Before You Click: Before clicking a link, hover your mouse over it to see the actual URL. If it looks suspicious or doesn't match the destination, don't click it.
• Don't Open Unexpected Attachments: Email attachments, especially from people you don't know, are a common way for viruses to spread. Verify with the sender before opening them.
• Think Before You Download (and Avoid Unofficial Sources):Only download software from official, trusted sources like the developer's website or an official app store. Downloading from unofficial sources is extremely risky for these reasons:
  • Malware and Viruses: These downloads are a prime delivery vehicle for malware, including ransomware, spyware, and Trojans.
  • No Security Updates: Unofficial and pirated software often can't be updated, leaving you exposed to new vulnerabilities.
  • Spyware and Adware: "Free" or "cracked" software is frequently bundled with hidden spyware that tracks your activity or adware that floods your system with pop-ups.
  • No Support or Accountability: If something goes wrong, you have no technical support or recourse.

3. Stay Up to Date with Updates​

Software updates are not just for new features; they are a critical security necessity.

• Enable Automatic Updates: Configure your operating system, web browser, and other critical software to update automatically.
• Don't Ignore Update Notifications: These updates often patch newly discovered vulnerabilities. Install them promptly to close security holes before they can be exploited.

4. Understand the Dangers of Public Wi-Fi​

The convenience of public Wi-Fi comes with significant security risks.

• Assume No Privacy: Public Wi-Fi networks are often unsecured, and your data could be visible to others on the same network.
• Use a VPN: A Virtual Private Network (VPN) encrypts your internet traffic, creating a secure tunnel that protects your data from prying eyes.
• Avoid Sensitive Activities: Never access your bank account, shop online, or perform other tasks that involve sensitive information while connected to a public Wi-Fi network.

5. Back Up Your Data Regularly​

This is your last line of defense. If all your preventive measures fail and you get infected with ransomware or your hard drive fails, a backup is what saves your data.

• Follow the 3-2-1 Rule:
  • 3 copies of your data (the original plus two backups).
  • 2 different types of media (e.g., an external hard drive and cloud storage).
  • 1 copy stored offsite (e.g., in the cloud or at a different physical location).
• Automate Your Backups: Use backup software to automate the process, ensuring that your data is backed up consistently without you having to remember to do it manually.
• Verify Your Backups: Periodically check to make sure your backups are working and that you can restore your files.

By making these habits a regular part of your routine, you can build a formidable and resilient defense against a wide range of online threats.

I would add another good habit: avoid going online while signed in to your admin account. Exceptions are when you cannot find an offline installer for your app and must be online to install it. And another exception is when you need to fix networking. Otherwise avoid as much as possible.

One app that has a vulnerability is all it takes for an adversary to take on your admin rights and pwn your pc. How many of us diligently patch our apps? Or pay attention to security advisories?
