Cybersecurity Awareness Month

This October, we are joining the global celebration of Cybersecurity Awareness Month, aimed at raising awareness about the importance of online security. Throughout our Cybersecurity October, we will share practical tips on safe remote and office work, as well as show you how to effectively protect yourself against various attacks. Stay tuned!

1. Keep Your Desk Organized

  • Don’t leave documents, notes, or sticky notes with passwords in plain sight (in general, avoid writing down passwords on paper).
  • Sort and archive papers – immediately shred unnecessary documents or scan them into electronic systems.
  • Maintain cleanliness in shared spaces, such as conference rooms and near printers.

2. Safe Use of Printers and Copiers

  • Collect printouts immediately after printing.
  • Don’t leave documents on printer or copier trays.
  • Shredding documents containing sensitive information (e.g., using a shredder) is a daily security responsibility.

3. Digital Cleanup

  • Regularly review folders on your computer and cloud storage – delete or archive files that are no longer needed.
  • Clear your browser cache and delete temporary files.
  • Secure your recycle bin – remember that deleting a file does not always mean it is completely erased.

4. Small Device Habits

  • Lock your computer screen when stepping away from your desk, even briefly.
  • Do not leave smartphones, USB drives, or tablets unattended.
  • Ensure mobile devices are protected with a PIN or biometric lock after use.

5. Vigilance with Documents and External Media

  • Do not connect unknown USB drives or external disks.
  • Verify the source of any media or files you receive.
  • Shredding or encrypting sensitive data after use minimizes the risk of leaks.

Why Are These Small Actions Important?

Daily attention to organization and conscious habits reduces the risk of accidental data disclosure and social engineering attacks. While they may seem minor, they have a real impact on the security of the entire organization.
