Traditionally, the foundation of cyber security has rested on the well-known CIA Triad, Confidentiality, Integrity, and Availability. Every security professional, auditor, and regulator has used these three principles as the benchmark for evaluating the adequacy of information security controls.
The CIA model has served the digital world well. However, Data is no longer merely an information asset stored in computers. It directly influences human decisions, determines access to services, impacts financial outcomes, and in sectors such as healthcare, can literally affect life and death.
Consequently, cyber security can no longer remain confined to protecting information systems. It must evolve into a discipline that protects the human beings whose lives are influenced by the information.
It is therefore time to rethink the traditional security architecture and move from the CIA Information Triad to what may be called the CDP Human Triad particularly in the context of the hospital systems.
What is CDP Human Triad?
The CDP human triad represents the CISO who protects the Information, DPO who protects the Privacy and the PSO who protects the Patient.
The traditional CIA model focuses on protecting information.
- Confidentiality ensures that information is not disclosed to unauthorized persons.
- Integrity ensures that information is not altered without authorization.
- Availability ensures that information is accessible when required.
This approach was adequate when information systems were viewed primarily as repositories of data. However, modern cyber incidents demonstrate that the ultimate impact of a breach is often not on information but on people.
A ransomware attack on a hospital may compromise availability, but its real consequence may be delayed treatment.
An AI system that generates an incorrect recommendation may preserve confidentiality and availability, yet still expose an individual to harm.
A privacy violation may not damage the data itself, but may undermine the autonomy and choice of the individual to whom the data relates.
The focus of security therefore needs to shift from merely protecting information assets to protecting human interests.
The proposed CDP Human Triad consists of three human controllers with their own respective responsibilities.
C: CISO the person responsible to ensure the Confidentiality, Integrity and Availability of personal data of data principals. (Patients in the Hospital context).
D: DPO the person responsible to ensure that the Privacy rights of the Patients are protected as per the laws such as DPDPA.
P: Represents the person responsible to protect the Patient Safety during the Health Cre operations.
We must appreciate that a system may be perfectly secure from CIA triad concept but still it may not be compliant with DPDPA requirements. A system may be DPDPA compliant but may result in adverse patient safety considerations.
Hence when we address an issue such as a “Data Breach”, we need to recognize that the consequence cannot be considered fully reversed with a restoration of lost data or correcting a consent shortage since the damage on human life remains irreversible. Hence a “Data Breach” in a hospital context is not the same as a data breach in a Bank or any other system.
Hence the remedies need to be also different. The CDP approach is recommended to meet this requirement.
The transformation from CIA to CDP naturally requires a corresponding evolution in organizational governance.
The CISO continues to focus on:
-
- Information security
- Network security
- Cyber defence
- Incident response
- Business continuity
- Technology resilience
The CISO asks:
“How do we protect the information and systems?”
The DPO: Protecting the Data Principal’s Choice
The DPO focuses on:
-
- Consent governance
- Privacy compliance
- Data Principal rights
- Purpose limitation
- Data minimization
- Breach notification obligations
The DPO asks:
“How do we protect the individual’s choices and rights?”
The PSO: Protecting Patient Safety
The PSO focuses on:
-
- Clinical safety
- Human impact assessment
- Digital risk to patient care
- AI safety oversight
- Safety incident management
- Harm mitigation
The PSO asks:
“How do we protect the patient, irrespective of the cause of harm?”
This is an key distinction.
The PSO is not concerned only with cyber attacks. The concern extends to any digital or operational event that may compromise patient safety, whether arising from technology failure, human error, AI malfunction, privacy violations, or malicious activity.
A Shift in Security Thinking
The significance of this transition lies in recognizing that the purpose of security is not security itself.
The ultimate purpose of security is to protect human interests.
Historically, security professionals protected servers, networks, databases, and applications.
Today they must also protect:
- Human autonomy,
- Human dignity,
- Human rights,
- Human safety.
The transition from the CIA Information Triad to the CDP Human Triad represents this broader vision.
It acknowledges that:
- Information must remain confidential.
- Individuals must retain control over their personal data.
- Patients and other affected individuals must remain safe irrespective of how a digital failure occurs.
As organizations adopt AI, digital health platforms, connected devices, and data-driven decision-making systems, cyber security architecture must evolve beyond its traditional boundaries.
The future governance framework cannot rely solely on the CIA Triad.
A more human-centric model is required—one that integrates technical security, privacy governance, and safety assurance.
How do we integrate the CISO-DPO-PSO triad in our current system?
The CISO–DPO–PSO triad provides the organizational mechanism for achieving this objective, while the CDP Human Triad provides the corresponding security philosophy.
The challenge before regulators, industry leaders, healthcare institutions, and security professionals is to ensure that this transition in the very objective of security is recognized, embedded, and protected.
The attempt to find a solution falls on the DGPSI-Hospital framework which is being developed as an extension of DGPSI.
In the military structure we have identified the post of “Chief of Defense Staff” (CDS) to have a joint command on Army, Navy, Airforce and Cyber commands. Similarly, should we consider a Patient Safety Officer as a central command over DPO and CISO or should we identify a new designation is the question which we need to answer in DGPSI.
Await the release of the DGPSI-Hospital for the final suggestion.
