Any casual news consumer understands that there is cause for some trepidation about the mobile security of our systems, especially after the crippling cyberattacks of the last few weeks and months. For instance, the most recent global attack, a massive ransomware attack that struck this week, succeeded in crashing the computer systems of many big businesses across multiple industries, from pharma to energy to manufacturing to shipping.
More ominously, these attacks no longer look like one-off’s. Instead, mobile security watchers like CNET writer Alfred Ng speculate that an actual global ransomware epidemic might be beginning. How then should we safeguard our mobile security? Bear in mind that protecting your own computer might not even be enough to ensure complete mobile security, when someone on your work network might unsuspectingly download malware, either through email or attachments. Remember: 97 percent of phishing emails deliver ransomware.
Well, you might not manage to fend off the most determined cyberattack, but you can do a lot of simple things to limit your exposure, like modifying your online behavior
- Never open spam emails or emails from unknown senders, in other words look closely at the “from” line of your emails.
- If you open, don’t click. Don’t download attachments from suspicious emails or click on embedded links.
- Business users most likely have a reliable antivirus service on their computers. But make sure you keep your antivirus service up to date. Better yet, set the service to automatic update so you don’t have to remember.
- Relatedly, make sure all of the latest security patches have been applied, both to your OS and to your apps. That means you have to constantly run updates, which often include bug fixes and security upgrades.
- Adjust your browser’s security and privacy settings to better protect yourself.
- Avoid free, unsecured public Wi-Fi.
- And if you have no choice, make sure you’re using a VPN (Virtual Private Network).
