Data security has always been at the forefront of a business, but with the latest, not to mention drastic, uptick in security breaches, it's more important than ever.   Testing data security and data recovery is HUGE for a business.  Testing your disaster recovery plan helps determine the critical, business functions as well as the importance, and impact, those functions have on the business. Testing can expose the losses a business will retain when any of those functions are interrupted, or worse, halted.  It's important to know the best practices of security testing, but equally important, is having a plan in the event a breach occurs.  Hence the introduction of the Disaster Recovery Runbook.
