Post Equifax computer security

Some thoughts on computer security post Equifax.  Equifax is different from say the 2013 Yahoo hack that stole usernames and passwords.  Equifax has a full file of your social security number, your drivers license number and a collection of assets, loans and bank accounts.  Yup they have been collecting data on each of us for years.  So someone could impersonate you with all this stuff and you might not know it.
