Protecting your personal information in today’s digital world is more important than ever. But for those of us who aren’t tech wizards, navigating the world of data protection and privacy can feel like trying to decipher ancient hieroglyphics. Fear not! This article will help you understand the basics of data protection and data privacy so you can keep your digital life secure.
- “The Digital Fishing Expedition” – Phishing attacks are on of the hackers top tactics for getting access to your data. Imagine this: You receive an email that appears to be from your financial institution. The email indicates you need to “verify” your account details by clicking on a link in the email. You click on it, enter account information and ta-da! Congratulations, you just handed the digital goblins the credentials needed to access your banking accounts.
- “Oversharing on Social Media” – Have you ever heard the term TMI? It stands for “Too Much Information”. TMI is not your friend when it comes to your Facebook and other social media accounts. Posting every moment and detail of your personal life to your social media accounts is the equivalent of creating a roadmap to all your personal information and then handing it over to an identity thief. Use common sense when posting to avoid getting your identity stolen. Identify theft can be a real nightmare to deal with.
- “Weak Passwords” – If you read more than one of our articles or perused the rest of the Security for Nerds site, then you’ve probably noticed password security is one of, if not the, most crucial security lesson to learn. Using weak passwords such as “password123” is like adding a neon sign to your front door that says “All Thieves Welcome”. If you have done so already, be sure to checkout our article on Password Security.
None of us are perfect. Even some of the most technically competent and experienced people sometimes fail to protect their data. Yes, I’m talking about all those people with Computer Science, Information Technology, etc. degrees. Still not convinced? Checkout these real-life disaster stories.
When Things Go Wrong: Three Examples of Real-Life Data Disasters
- The LinkedIn Leak: In April 2021, data from over 700 million LinkedIn users was scraped by hackers and posted online. This included full names, email addresses, phone numbers, and more. While most of this information was publicly available, the incident highlighted how easily personal data can be collected and potentially misused. The Fallout: Users faced increased risks of phishing attacks and identity theft. Imagine receiving a “job offer” email that looks legit because it has all your professional details – that’s the kind of scam this leak enabled.
- The DeepSeek Debacle: In early 2025, the Chinese AI (Artificial Intelligence) app, DeepSeek, made headlines for all the wrong reasons. Millions of users, including government workers, unknowingly shared their sensitive personal data while using the app. The Damage: The incident led to data leaks, prompting South Korea to remove the app from stores and other countries to ban it on government devices. Users who shared sensitive information faced potential privacy violations and security risks.
- The Equifax Breach (Ongoing Consequences): While the Equifax breach occurred in 2017, its effects continue to be felt. The breach exposed the personal information of 147 million people, including Social Security numbers, birth dates, addresses, and in some cases driver’s license numbers. The Aftermath: Years later, affected individuals still face increased risks of identity theft and financial fraud. Some have reported unauthorized accounts opened in their names, damaged credit scores, and countless hours spent trying to secure their identities.
In today’s fast paced digital world it’s easy to become a victim, so slow down and take a little time to think before you click. Device and software security tools can help protect your personal information, but it can only do so much. It’s up to you to stay alert and on the lookout for threats to your data. Here are some of the most common data protection mistakes you should be aware of.
- Ignoring Software Updates – Completing that software update at a later time might seem harmless, but would you wait to patch holes in your boat while sailing in shark-infested waters?
- Clicking on Those Suspicious Links – Don’t let that “You’ve won a free trip!” email tempt you. Clicking on it’s link or attachment, might be trying to take you on a journey to identity theft.
- Using Public Wi-Fi Connections Without Protection – Always take precaution when using free wi-fi connections. Using a public wi-fi connection, like those found at airports, without proper protection is like shouting out your personal information in a large crowded room.
Data Protection…
- Encrypt Your Devices: Turn on device encryption to scramble your data. Encryption is like writing all your secrets in a code only you can understand
- Back Up Your Data: Similar to making copies of your family photos in case your house burns down, you should regularly back up your important files to a secondary storage device.
- Use Antivirus Software: Create a digital immune system to fight off nasty digital viruses. Install your antivirus software and keep it current with the latest software updates.
Data Privacy…
- Read Privacy Policies: Yes, they’re boring, but knowing how companies are using your data may surprise you. Remember, the app is free for a reason. Just like checking the ingredients list to avoid allergic reactions. You should always check what apps are doing with your information.
- Manage App Permissions: Regularly review and adjust your app permissions. If your flashlight app needs access to all of your contacts, find out why.
- Use Privacy-Focused Services: Look for services that prioritize user privacy. If you’re choosing a bank with top-notch security, you sure wouldn’t choose the one that keeps your money in a vault.
It’s important to remember, in today’s digital world, YOU are your own best defender. Stay vigilant and stay safe. You can significantly reduce your risk of becoming a victim of cybercrime by time in understanding the basics of data protection and privacy, and implementing some simple security measures. The cautious survive and thrive in the digital world, so the next time your tempted to use “password” as your password or to share your life story on social media, pause and think about it!
