Password First
Ideally, usernames and passwords should be unique for every service or site that requires you to use these credentials. Why? If one username and password gets compromised, they all do.
Security Question, Check
When choosing security questions, try to avoid questions to which answers can be found by taking one glance online, for example, on your Facebook or Twitter profile. The most secure method is to choose questions that require very specific answers like, “What was the last name of your third grade teacher?”
Don’t Think, Just Backup
It may be strange to be told to backup data on a physical, external drive when it comes to securing Cloud data, but it’s never a bad idea. Better safe than sorry.
Delete When Done
You might be thinking, why bother deleting anything when there are limitless data storage options in the Cloud. But, you never know if data can later become a potent risk. If an e-mail or document with confidential information has outlived its worth, delete it.
