The healthcare sector is present process digitalization and adopts new applied sciences to enhance affected person care, provide new companies for distant sufferers and attain operational excellence. The combination of latest applied sciences within the complicated healthcare IT infrastructure creates new challenges relating to information 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 goal to gather person credentials in addition to ransomware assaults that search to encrypt the information of hospitals.

Alternatively, 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 techniques together with well being data techniques like digital well being data, information analytics, medical units and telemedicine.

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

Legislative background

In keeping with the European Union NIS Directive, hospitals are outlined as Operators of Important Providers (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 information as a “particular class” of private information, which is delicate by nature and imposes a better normal of safety for his or her processing. Healthcare organizations as information controllers that are processing medical information should implement acceptable technical and administration measures to make sure the safety of techniques, companies and information. Additional, cloud suppliers are thought-about information processors beneath GDPR as they’re performing on behalf of the information controllers; therefore, they’ve obligations as information controllers.

The report reminds healthcare organizations migrating to the cloud that the Shared Accountability Mannequin applies, that’s, cloud clients 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 information 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 information privateness challenges.

Cloud safety challenges

Lack of belief: Stakeholders within the healthcare sector equivalent to sufferers, physicians, and medical employees indicated an absence of belief of cloud options. To fight this, it’s useful to lift consciousness for cloud safety points and prepare personnel in identification, authentication and entry administration mechanisms. With out coaching and schooling, human error and social engineering assaults are more likely to prevail.

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

Cybersecurity funding is just not 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 information safety maturity within the healthcare sector.

Regulatory compliance of cloud suppliers: Healthcare is a closely regulated business. Consequently, 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 techniques: The combination of cloud options with present infrastructure is difficult and motivates some organizations to chorus from utilizing cloud companies. In lots of instances, legacy techniques 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 techniques are extra weak to cybersecurity assaults.

Knowledge safety challenges

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

Knowledge governance: Healthcare organizations accumulate and handle affected person information. This data is both routinely transferred to the cloud by way of medical linked units, or it’s submitted by medical practitioners. Knowledge accuracy is crucial for healthcare suppliers. Organizations want to ascertain information governance insurance policies to determine and classify delicate information after which apply controls to make sure information accuracy.

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

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

Cloud safety finest practices

To handle these challenges, ENISA suggests implementing the next safety and information safety measures.

Establish safety and information safety necessities equivalent to laws, inner insurance policies and authorized necessities for particular merchandise.Conduct a threat evaluation and information safety affect evaluation to determine cybersecurity and information safety threats and dangers for cloud deployments and consider the affect of the general threat.Set up processes for safety and information 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 enough backup and determine the cloud supplier’s duties within the occasion of a service disruption.Establish catastrophe restoration necessities and be sure that the catastrophe restoration and information restore processes of the cloud service supplier meet these necessities.Make sure the group’s information are both eliminated upon contract termination or deleted if information retention interval has expired.Outline necessities for occasion logging and steady monitoring.Decide and setup processes for vulnerability and patch administration.Establish, stock and classify information saved in cloud environments.Allow and guarantee encryption for information at relaxation and in transit.Outline safety necessities for key administration and guarantee procedures for key administration are carried out.Guarantee all information is supplied in a standardized format upon request from the cloud supplier.Establish and stock all units and endpoints and outline safety baseline for hardening these property.Guarantee and implement robust authentication and entry controls.Set up common, focused consciousness and coaching applications for workers and companions.Make sure that visitors between untrusted and trusted environments is restricted and monitored.Apply segmentation practices in accordance with need-to-know, least-privilege rules.Make sure the cloud service supplier offers bodily safety controls to guard information 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 information safety challenges that should 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.
