2021 Cybersecurity Spring Cleaning Checklist

March 23, 2021 | Michael Aliperti, MS-ISAC Chair

Spring is not just a good time for cleaning your house or apartment, it's also a good time to clean up your technology and cyber footprint.

Throughout the year, especially around the holidays and during tax season, you extend your cyber footprint by paying bills, shopping, using social media, and many other digital activities whether for business or pleasure. Spring cleaning your space is meant to improve the air quality after having it closed up all winter, and cleaning can improve your mood and remove a year’s worth of clutter. Cleaning your technology and cyber footprint can do the same thing; it removes clutter from your life while at the same time protecting you and your loved ones.

While spring cleaning, you often make a list to ensure you don't forget to clean the spots you don't normally think about, like behind the sofa or on top of the fridge. To help you spring clean your technology and cyber footprint, we have developed a checklist to help you through the process. And just like spring cleaning your house, you can assign these tasks to your family.


  • Review your passwords, updating them as needed, and ensuring they are strong.
  • Establish a unique password for each account.
  • Consider using a password manager if you haven't in the past.
  • Remember to use Multi-Factor Authentication (MFA) on accounts wherever it is available, especially on accounts that have financial information such as online banking, credit card, and retirement accounts.


  • Review all your email accounts.
  • Organize folders of emails that you want to keep, delete and purge emails that you no longer need.
  • Be sure that there is no personally identifiable information stored in your mailbox.
  • Review and update your contacts. Delete contacts that are no longer necessary or current.
  • Review and update email filters to send spam and unwanted e-marketing messages directly to trash or another folder.

Social Media

  • Review social media accounts and associated privacy settings.
  • Review any photos or videos and delete those that you no longer need or want to make viewable.

  • Review your backup schedule, and what you're backing up.
  • Test your backups and validate they are being successfully completed.
  • Make sure you can restore from a backup.

Cleaning can be a very satisfying process. If cleaning is not normally your idea of a good time, we hope that you’ll find this technology and cyber spring-cleaning checklist a way to speed up the process. Have fun getting rid of some clutter, and don't forget to have your kids clean under their beds!
