You can never be 100% secure from attackers. You can improve your security and slow down attackers from infecting and harming your devices.
Here are quick 7 tips that you can apply to ensure your safety:
1. Be conscious of privacy issues
Knowing the importance of passwords and pins is the first step in protecting your devices from unauthorized access. Have strong pins and passwords that are not easy to guess, related to things you love or own eg. birthdays, or pet names. Keep them private only known to you and change them regularly.
2. Change computers with each visit.
When using public computers, make a habit of using different devices on each visit. This prevents cookies from saving your activity on a specific machine
3. Browse on incognito mode.
Always log in to your accounts by using private or incognito browsers when using public or shared devices. To avoid saving your history of sites you visited and also prevent saving your log-in details on a browser.
4. Don’t save your files on public computers.
When you download files, work on them and delete them. Do not leave personal files saved on shared devices. The information found on those devices may be used wrongfully.
5. Avoid inserting your devices into public computers.
Some public computers are infected. Once you insert a device like a USB stick, the infection could transfer to your USB / phone, and can eventually infect your system when you plug in. Use cloud transfers when needed.
6. Check website security.
Ensure that the sites you visit are certified. A quick way to check is to see if it starts with HTTPS:// instead of HTTP://. Most websites with HTTP:// are not safe to visit, stay away. When trying to visit some sites, you may get a security warning when you are advised to proceed with caution at your own risk. When you see such warnings, abort the mission.
7. Hard delete your documents after work.
In shared devices, ensure you delete the files and documents that you have worked on. Not just sending to recycle bin, these can be retrieved. Erase them permanently from the recycle (trash) bin too. If you have printed documents, and do not need them, carry them along and shred them.
