Week 3: Best Practices with Your Devices

WEEK 3.png

 

In today's digital world, our devices are essential tools, both at work and in our personal lives. But with the benefits of these devices come risks. Following best practices can help safeguard your data and ensure your devices remain secure. Below are some critical steps to take:

1. Keep Your Devices Up to Date

Outdated software is one of the easiest ways for cybercriminals to exploit vulnerabilities. Regular updates often include patches for known security flaws, protecting your devices from newly discovered threats. Make it a habit to:

  • Turn on automatic updates for your devices.
  • Regularly check for system updates on all platforms, including macOS, Windows, iPhone, and Android.
  • Don't ignore update notifications—they are crucial for keeping your device secure.

2. Restart Regularly and Know Why It Matters

Many people keep their devices running continuously without restarting, but restarting is essential for several reasons:

  • Performance: Restarting helps free up memory and stop background processes that can slow down your device.
  • Security: Many updates and patches aren't fully installed until you restart your device. By restarting regularly, you're helping to ensure your security updates are applied properly.

3. Software Updates: MacOS, Windows, Adobe, and More

It’s not just about your operating system—software applications like Adobe, Microsoft Office, and web browsers also require regular updates. Here’s why it's important:

  • These applications often have access to sensitive data.
  • Keeping these programs updated ensures you're protected from vulnerabilities in widely used software.

Make sure your key applications are set to update automatically or check for updates regularly in their settings.

4. iPhone/Android Updates

Mobile devices store a lot of personal and sensitive data. Ensuring your iPhone or Android phone is up to date helps you:

  • Stay ahead of the latest security threats.
  • Take advantage of the latest features and performance improvements.
  • Protect your data, which is increasingly targeted by mobile-specific malware and phishing attacks.

5. Don’t Reuse the Same Password Across Services

Password reuse is a major security risk. If one account gets compromised, cybercriminals can try that same password across different services. Follow these guidelines:

  • Use a unique password for each account.
  • Consider using a password manager to securely store and generate strong, unique passwords.
  • Ensure passwords are long and include a mix of letters, numbers, and symbols.

6. Check for Compromised Passwords Using 'Have I Been Pwned'

Even the strongest passwords can be compromised in data breaches. 'Have I Been Pwned' (https://haveibeenpwned.com/) is a free service that allows you to check if your email or passwords have been part of a known breach. Here's how to use it:

  • Visit the website and enter your email address or password to see if it's been compromised.
  • If your information is part of a breach, change your passwords immediately.

By following these best practices, you’ll improve the security of your devices and protect yourself against many common threats. Remember, cybersecurity is an ongoing process—stay vigilant and keep your devices secure!
