The table below summarizes security and speed implication of different ways of accessing sensitive data while working out of office.

Note that the comparison only lists most popular ways of storing data and the Security/Speed correspond to typical situation – in the real world access speed and security provided by local encryption vary.

Note also that simple password protection of files/disks/computers (without encryption) has been simply ignored in this analysis as it does not provide any realistic protection of data.



Notes about security:
  1. Poor means that anybody who gains access to the files can read them.
  2. Very Poor means that – in addition – access to files is easy for anybody
  3. Average means that either access to files is difficult for strangers or that opening files requires serious effort and expertise The difficulties involved in this depend on many elements (pass phrase quality, server security – network and physical), but generally this term means that the files can be accessed given enough time and effort.
  4. Good means that the cost involved in a possible cracking of the security system (if at all possible) is significantly higher than the potential value of the data. This also means that the strength of the security system may be configured depending on the value of the protected data. Most importantly it means that access to data can be monitored, audited and centrally controlled.
