Thank you for visiting our blog.
I think you send a file by email compressing it and setting a password.
Although you do that to protect the secrets of the file against others, someone set it in vain.
For example, if you give a hint like “the password is four digits of your phone number.”, it is possible to find the password in a few seconds with a password analysis tool.
In the same way, in case you use a password composed of six digits of alphabets and numbers, it is possible to find your password in a few minutes.
It might be better to use a password with more than eight digits of alphabets, numbers and symbols since it takes more time to find, but it is even possible to find it, so you should not send a file including a secret information like individual information.
You need take a measure to avoid an access to thesee information from others.
It is necessary to prepare an environment and give an education to avoid unconscious information leakage.
