HOW WOULD THE DECISION SUPPORT TOOL HANDLE SENSITIVE ORGANIZATIONAL OR FINANCIAL DATA

Any decision support tool that processes sensitive organizational or financial data would need to have very strong data security and privacy protections built directly into its system architecture and functionality. At the highest level, such a tool would be designed and developed using privacy and security best practices to carefully control how data is stored, accessed, and transmitted.

All sensitive data within the system would be encrypted using industry-standard methods like AES-256 or RSA to ensure it remains encrypted even if the underlying data was somehow compromised. Encryption keys would themselves be very securely managed, such as using key vaults that require multiparty controls to access. The system would also implement server-side data masking to hide sensitive values like credit card numbers, even from authorized users who have a legitimate need to access other related data.

From an authorization and authentication perspective, the system would use role-based access control and limit access only to authorized individuals on a need-to-know basis. Multi-factor authentication would be mandated for any user attempting to access sensitive data. Granular access privileges would be enforced down to the field level so that even authorized users could only view exactly the data relevant to their role or job function. System logs of all access attempts and key operations would also be centrally monitored and retained for auditing purposes.

The decision support tool’s network architecture would be designed with security as the top priority. All system components would be deployed within an internal, segmented organizational network that is strictly isolated from the public internet or other less trusted networks. Firewalls, network access controls, and intrusion detection/prevention systems would heavily restrict inbound and outbound network traffic only to well-defined ports and protocols needed for the system to function. Load balancers and web application firewalls would provide additional layers of protection for any user-facing system interfaces or applications.

Privacy and security would also be built directly into the software development process through approaches like threat modeling, secure coding practices, and vulnerability scanning. Only the minimum amount of sensitive data needed for functionality would be stored, and it would be regularly pruned and destroyed as per retention policies. Architectural controls like application isolation, non-persistent storage, and “defense-in-depth” would be used to reduce potential attack surfaces. Operations processes around patching, configuration management, and incident response would ensure ongoing protection.

Data transmission between system components or to authorized internal/external users would be thoroughly encrypted during transport using algorithms like TLS. Message-level security like XML encryption would also be used to encrypt specific data fields end-to-end. Strict change management protocols around authorization of data exports/migration would prevent data loss or leakage. Watermarking or other techniques may be used to help deter unauthorized data sharing beyond the system.

Privacy of individuals would be protected through practices like anonymizing any personal data elements, distinguishing personal from non-personal data uses, supporting data subject rights to access/delete their information, and performing regular privacy impact assessments. The collection, use, and retention of personal data would be limited only to the specific legitimate purposes disclosed to individuals.

Taking such a comprehensive, “baked-in” approach to information security and privacy from the outset would give organizations using the decision support tool confidence that sensitive data is appropriately protected. Of course, ongoing review, testing, and improvements would still be required to address new threats over time. But designing privacy and security as architectural first-class citizens in this way establishes a strong baseline of data protection principles and controls.

A decision support tool handling sensitive data would need to implement robust measures across people, processes, and technology to secure that data throughout its lifecycle and use. A layered defense-in-depth model combining encryption, access controls, network security, secure development practices, privacy safeguards, operational diligence and more provides a comprehensive approach to mitigate risks to such sensitive and potentially valuable institutional data.
