The healthcare sector is present process digitalization and adopts new applied sciences to enhance affected person care, supply new companies for distant sufferers and attain operational excellence. The mixing of recent applied sciences within the complicated healthcare IT infrastructure creates new challenges concerning knowledge safety and cybersecurity.

On the one hand, the COVID-19 pandemic has been a driver for elevated cyber-attacks on healthcare organizations together with phishing assaults that purpose to gather person credentials in addition to ransomware assaults that search to encrypt the information of hospitals.

However, the pandemic has helped to emphasize the necessity for distant healthcare companies. Cloud platforms have supplied the elasticity and quick entry required for the deployment of those companies. Organizations subsequently deployed cloud options to cowl ERP programs together with well being info programs like digital well being data, knowledge analytics, medical units and telemedicine.

To assist IT professionals in healthcare safety to ascertain and keep cloud safety whereas deciding on and deploying applicable technical and organizational measures, ENISA issued a examine that goals to offer cloud safety practices for the healthcare sector.

Legislative background

In accordance with the European Union NIS Directive, hospitals are outlined as Operators of Important Companies (OES), whereas cloud suppliers are Digital Service Suppliers (DSP). Subsequently, each hospitals and cloud distributors should adjust to the NIS Directive safety necessities when contracting with cloud companies.

On the similar time, the GDPR defines medical knowledge as a “particular class” of private knowledge, which is delicate by nature and imposes a better commonplace of safety for his or her processing. Healthcare organizations as knowledge controllers that are processing medical knowledge should implement applicable technical and administration measures to make sure the safety of programs, companies and knowledge. Additional, cloud suppliers are thought of knowledge processors underneath GDPR as they’re performing on behalf of the information controllers; therefore, they’ve obligations as knowledge controllers.

The report reminds healthcare organizations migrating to the cloud that the Shared Duty Mannequin applies, that’s, cloud prospects and cloud suppliers have sure safety necessities within the cloud (the shoppers) and of the cloud (the suppliers).

Determine 1: Cloud safety shared duties. Supply: ENISA

Whereas migrating to the cloud, healthcare organizations are going through safety and knowledge safety challenges. The authors of the ENISA report interviewed healthcare professionals in Europe to discover these obstacles. These respondents recognized the next cloud safety and knowledge privateness challenges.

Cloud safety challenges

Lack of belief: Stakeholders within the healthcare sector equivalent to sufferers, physicians, and medical employees indicated a scarcity of belief of cloud options. To fight this, it’s useful to boost consciousness for cloud safety points and practice personnel in identification, authentication and entry administration mechanisms. With out coaching and training, human error and social engineering assaults are prone to prevail.

Lack of safety and know-how experience: Migrating your entire on-premises IT infrastructure or particular person companies to the cloud requires personnel who perceive cloud applied sciences and the related safety and knowledge safety facets. Nonetheless, the demand for cloud safety specialists within the healthcare sector is increased than its provide, hindering cloud computing development.

Cybersecurity funding will not be a precedence: Lack of administration buy-in and restricted public financing leads to much less help to advertise the digitalization efforts and to extend cybersecurity and knowledge safety maturity within the healthcare sector.

Regulatory compliance of cloud suppliers: Healthcare is a closely regulated business. Because of this, organizations are going through difficulties figuring out cloud distributors which can be compliant with their authorized necessities, thereby limiting their choices.

Integration of cloud with legacy programs: The mixing of cloud options with current infrastructure is difficult and motivates some organizations to chorus from utilizing cloud companies. In lots of instances, legacy programs which can be a part of well being IT infrastructure can’t be up to date, which complicates integration and interoperability with new applied sciences. Consequently, these programs are extra susceptible to cybersecurity assaults.

Information safety challenges

Privateness by design strategies: The GDPR introduces a authorized requirement on privateness by design and by default for each knowledge controllers and knowledge processors. Subsequently, healthcare organizations want to make sure that cloud distributors make use of such an strategy when growing and deploying the service.

Information governance: Healthcare organizations accumulate and handle affected person knowledge. This info is both routinely transferred to the cloud through medical related units, or it’s submitted by medical practitioners. Information accuracy is important for healthcare suppliers. Organizations want to ascertain knowledge governance insurance policies to determine and classify delicate knowledge after which apply controls to make sure knowledge accuracy.

Information deletion: This can be very vital to have the ability to erase knowledge after retention time has expired or upon the information topic’s request with out undue delay. Nonetheless, efficient knowledge deletion is a technical problem.

Encryption: Encryption is vital to make sure secrecy and integrity, and it have to be utilized each to knowledge at relaxation and knowledge in transit. Encryption must be carried out at client- and server-side but in addition within the channel connecting them.

Cloud safety greatest practices

To deal with these challenges, ENISA suggests implementing the next safety and knowledge safety measures.

Determine safety and knowledge safety necessities equivalent to laws, inner insurance policies and authorized necessities for particular merchandise.Conduct a danger evaluation and knowledge safety influence evaluation to determine cybersecurity and knowledge safety threats and dangers for cloud deployments and consider the influence of the general danger.Set up processes for safety and knowledge safety incident administration and outline the actions to be taken after a cloud supplier safety incident. Outline roles and duties and align actions with the cloud supplier’s safety provisions.Outline enterprise continuity processes, assign roles and duties, guarantee satisfactory backup and determine the cloud supplier’s duties within the occasion of a service disruption.Determine catastrophe restoration necessities and be certain that the catastrophe restoration and knowledge restore processes of the cloud service supplier meet these necessities.Make sure the group’s knowledge are both eliminated upon contract termination or deleted if knowledge retention interval has expired.Outline necessities for occasion logging and steady monitoring.Decide and setup processes for vulnerability and patch administration.Determine, stock and classify knowledge saved in cloud environments.Allow and guarantee encryption for knowledge at relaxation and in transit.Outline safety necessities for key administration and guarantee procedures for key administration are carried out.Guarantee all knowledge is supplied in a standardized format upon request from the cloud supplier.Determine and stock all units and endpoints and outline safety baseline for hardening these belongings.Guarantee and implement robust authentication and entry controls.Set up common, focused consciousness and coaching applications for workers and companions.Make sure that site visitors between untrusted and trusted environments is restricted and monitored.Apply segmentation practices in accordance with need-to-know, least-privilege ideas.Make sure the cloud service supplier supplies bodily safety controls to guard knowledge facilities and forestall unauthorized bodily entry.


The adoption of cloud options by the healthcare organizations presents enhancements in availability, scalability and reliability of companies to distant sufferers. It introduces a number of safety and knowledge safety challenges that have to be addressed to speed up the digitalization of the healthcare sector. Healthcare organizations ought to implement the measures described within the ENISA report to make sure the reliability and effectiveness of their operations. Nonetheless, help is required from authorities and EU authorities to beat boundaries like understaffing and underbudgeting in hospitals.
