I've been working in cybersecurity education for a few years now and I keep seeing the same cybersecurity mistakes to avoid being made over and over. People think they're being safe but they're actually creating common security risks without realizing it.
The biggest one I see is password reuse across multiple sites. It's like using the same key for your house, car, and office if one gets compromised, they all do. Another major issue is not updating software regularly. Those update notifications aren't just annoying popups they're often fixing critical vulnerabilities.
What other cybersecurity mistakes to avoid do you see people making regularly? I'm trying to put together a comprehensive list for a workshop I'm running next month.
Great topic. One cybersecurity mistake to avoid that I see constantly is people disabling security features because they find them annoying. Like turning off Windows Defender because it slows things down, or disabling firewall prompts. They're trading short-term convenience for long-term risk.
Another big one is not backing up data properly. People think it won't happen to me" until it does. Regular backups are one of the most effective ways to recover from many common security risks.
I'd add using outdated devices that no longer receive security updates. So many people keep using old phones or computers because they still work, but they're not getting critical patches. This creates massive common security risks that are easily avoidable.
Also, people underestimate the risk of public charging stations. Juice jacking is real, though maybe not as common as some make it out to be. Still, better to use a power bank or bring your own charger.
From a network perspective, one of the biggest cybersecurity mistakes to avoid is not securing your home router. Default passwords, outdated firmware, and open guest networks are invitation for trouble. People spend time securing their computers but forget that the router is the gateway to everything.
Also, not using a VPN on public networks. I know you mentioned it in your Wi-Fi thread, but it's worth repeating here too. The number of people who do online banking on airport Wi-Fi without protection is terrifying.
Password-related cybersecurity mistakes to avoid could fill their own category. Beyond reuse, I see people writing passwords down on sticky notes (digital or physical), sharing passwords via email or text, and not changing default passwords on devices.
Another one is not checking if accounts have been involved in data breaches. Services like Have I Been Pwned are free and easy to use, but most people don't bother until it's too late.
Privacy mistakes often lead to security issues. Oversharing on social media gives attackers ammunition for social engineering. Posting vacation photos in real-time tells everyone your house is empty. Listing your pet's name, mother's maiden name, etc., gives answers to security questions.
Also, not reviewing app permissions. Why does a flashlight app need access to your contacts? People just click accept" without reading.
