  4. 4. With this organization in place the information PHI/PII Risk Indication (Figure 2) risk management program can be set in motion. Before describing the process in detail it is useful to consider alternative approaches. With pressure to meet the more stringent regulatory requirements imposed by the HITECH act, urgent deadlines to meet meaningful use requirements, and the need to react to day to day incidents, it is easy for a program to become derailed. Let’s consider the re- quirements required to comply with the HITECH act. Organizations must do the following: • Implement a data classification policy that describes the processes used to identify, classify, store, secure, and monitor access to PHI data. • Implement a process to detect a potential data breach and carry out an incident response plan. • Implement a notification process to inform Developing a broader view of risk to the business affected parties after a discovery of a breach allows the information risk management team to of security to PHI without unrea-sonable delay. avoid acting narrowly.

The IT organization needs to dis- cuss these risks so that management can make informed decisions and not hedge their bets be- cause they don’t believe IT can deliver on time. Another area to look at is consistent usage of risk severity levels and the associated actions. At Redspin we use five levels: Page 5 l
