Why Encryption For The Cloud Is A Good Idea

  1. 1. What exactly is the cloud?<br />
  2. 2. What exactly is the cloud?<br />No matter how you slice it, the cloud is just computers connected over a network<br />(the Internet) that you use remotely, for:<br /><ul><li>Processing
  3. 3. Data storage
  4. 4. Both</li></li></ul><li>What does it mean for my data to live in the cloud?<br />Basically, that your data lives on computers owned and controlled by someone else<br />
  5. 5. Is my data safe in the cloud?<br />Usually, yes. Your provider will generally have a security policy that details (among other things):<br /><ul><li>Policies for data recovery
  6. 6. Physical security
  7. 7. Internal policies for data privacy</li></ul>A good provider will have a security policy and take it seriously.<br />
  8. 8. Is my data truly privatein the cloud?<br />For the most part, yes, but not necessarily.<br /><ul><li>Data breach can occur
  9. 9. Internal privacy procedures may becircumvented
  10. 10. There may be weaknesses in policy enforcement</li></li></ul><li>Can encryption keep my data private?<br />
  11. 11. Encryption<br />Means your data cannot <br />be viewed, even if someone <br />else gets a copy.<br />(Unless they have a key.)<br />
  12. 12. Encryption<br />Modern encryption, with<br />a decently sized key, <br />is unbreakableeven by means <br />of modern computers.<br />
  13. 13. Encryption<br />Data that has been encrypted <br />can live anywhere, the cloud included, and is not viewable by anyone but the key holder.<br />
  14. 14. Hence…<br />+<br />Is a pretty good idea…<br />
