What is a HIPAA Security Risk Assessment?
The HIPAA Security Rule requires that covered entities (health plans, health care clearinghouses, and health care providers who electronically transmit any health information in connection with a HIPAA-related transaction), and business associates (read more about business associates here), implement security safeguards.
These security safeguards must protect the confidentiality, integrity, and availability of electronic protected health information (ePHI). ePHI is any protected health information that is created, stored, transmitted, or received in any electronic format.
Performing a HIPAA security risk assessment is the first step in identifying and implementing these safeguards. A security risk assessment consists of conducting an accurate and thorough assessment of the potential risks and vulnerabilities to the confidentiality, integrity, and availability of ePHI.
What is the Scope of a HIPAA Security Risk Assessment?
According to guidance issued by the Department of Health and Human Services (HHS), the scope of security risk assessment includes potential risks and vulnerabilities to the confidentiality, availability, and integrity of all ePHI that an organization:
- Creates;
- Receives;
- Maintains; and
- Transmits
This includes ePHI in all forms of electronic media. Types of electronic media include hard drives, CDs and DVDs, smart cards, personal digital assistants, and portable electronic storage devices.
The term “electronic media” is defined broadly, to include something as small as a single workstation, up to something as large complex networks connected among multiple locations. Security risk assessment must take into account all ePHI, regardless of the medium in which it was created, received, maintained, or transmitted, and regardless of its source or location.
Security risk assessment includes six elements:
- Collecting Data
- Identifying and Documenting Potential Threats and Vulnerabilities
- Assessing Current Security Measures
- Determining the Likelihood of Threat Occurrence
- Determining the Potential Impact of Threat Occurrence
- Determining the Level of Risk
Element 1: Collecting Data
To begin the security risk assessment, an organization must identify where its ePHI is stored, received, maintained, or transmitted. It can do this in several ways, by:
- Reviewing past or existing projects
- Performing interviews
- Reviewing documentation.
The data gathered on the ePHI gathered during data collection must be documented.
Element 2: Identifying and Documenting Potential Threats and Vulnerabilities
An organization must then identify and document threats to ePHI that are reasonably anticipated. Organizations must also identify and document vulnerabilities, which, if triggered or exploited by a threat, would create a risk of improper access to or disclosure of ePHI.
Element 3: Assessing Current Security Measures
For this part of the HIPAA security risk assessment, organizations should address their “state of security.” They should do so by:
- Assessing and documenting the security measures they use to safeguard ePHI.
- Assessing and documenting whether security measures required by the Security Rule are already in place.
- Assessing and documenting whether current security measures are configured and used properly.
Element 4: Determining the Likelihood of Threat Occurrence
Organizations must then assess the likelihood of potential risks to ePHI. The results of this assessment, combined with the list of threats identified in element 2, will reveal what threats should be regarded as “reasonably anticipated.”
Element 5: Determining the Potential Impact of Threat Occurrence
After an organization determines the likelihood of threat occurrence, it must assess the impact of potential threats to confidentiality, integrity, and availability of ePHI. This can be done by assessing the severity of the impact resulting from a threat that triggers or exploits a vulnerability. The assessment should be documented.
A useful way to document Impact severity, is by describing the severity numerically (i.e., assigning a number to how severe an impact is, on a scale of 1 to 10, with 10 being “most severe”).
Element 6: Determining the Level of Risk
The level of risk is determined by evaluating ALL threat likelihood and threat impact combinations identified in the risk analysis so far.
The level of risk is highest when a threat 1) is likely to occur; AND 2) will have a significant or severe impact on an organization. For example, if a network is completely unsecured, and that network stores all of the organization’s ePHI, two things are likely to happen: A threat will occur, and its occurrence may have a severe impact on the organization. When threat likelihood and severity are both high, the level of risk should be classified as “high.”
On the other hand, if there is a low risk of a threat occurring, AND the threat’s occurrence will have little to no impact on the organization, the level of risk is relatively low.
Once the organization has assigned risk levels, it should document those levels, and document what corrective actions are needed.
Finally, once all six elements have been addressed, all documentation should be finalized. In addition, the security risk analysis should be periodically reviewed, and updated, as needed.
