There are many different ways to go about this topic the one I am going to pick is a public key infrastructure (PKI). One of the security options that we are going to use is Privacy or confidentiality. This will keep all information secret from all people unless you are authorized to see it. This will help with employee’s not finding things that

The other method of securing files is by encrypting the information in the files using an Encrypting File System (EFS)‚ which employs public key encryption privileges (Strengthen Your Users ’ File Security‚ 2003).
