Crowdstrike created the Falcon platform, the world’s first cloud-native endpoint protection platform specifically built to stop breaches. The endpoint protection solution includes antivirus, cybercrime detection and response, and managed threat hunting. The company’s threat hunters are cybersecurity specialists who work 24/7 to help manage cloud data and identify attacks.
We present a post-quantum searchable encryption approach to enable a secure and efficient medical record system for digital twins. Public keys encrypt keys for transmission, while private keys allow decryption. Records containing personal, symptom and prescription data are encrypted before storage in the cloud. Hashes of encrypted records are recorded on the immutable blockchain using Merkle trees. It allows querying symptoms/prescriptions by person or keyword through the encrypted records.
Attribute-based encryption (ABE)
The BYOK encryption system encrypts the organization’s data, and the access to the information lies with the owner. But businesses need to be cautious while introducing this system as some plans upload the keys to the cloud security platform. In addition, there are considerations for acquiring data from the cloud that may be involved in litigation. These issues are discussed in service-level agreements (SLA). Scanning and penetration testing from inside or outside the cloud must be authorized by the cloud provider.

The threat of quantum computer attacks to digital twins
For each medical record, it is assigned a record number \(rec_i\), where the personal information, symptom and prescription are denoted by \(inf_i\), \(sym_i\) and \(pre_i\), respectively. Searchable encryption is to realize the search function in the case of encryption. At present, there are many files that need to be deleted or modified by the server. But sometimes some file contents don’t want the server to know and need to encrypt the file.
With nearly $2 billion in venture funding, the fast-growing startup boasts one of the highest valuations of private security companies. Read cloud security articles on cloud data protection, containers security, securing hybrid cloud environments and more. In modern-day enterprises, there has been a growing transition to cloud-based environments and IaaS, Paas, or SaaS computing models.

Management or CSPM looks at the configuration of your cloud platform accounts and identifies any possible misconfiguration leading to data breaches and leakage. Create a free account and access your personalized content collection with our latest publications and analyses. An example of security control that covers integrity is automated backups of information.
While cloud infrastructure has many benefits for business, there are certain barriers which can hinder cloud migration.
By encrypting records before cloud storage, verifying record integrity via blockchain, and allowing retrieval of encrypted data from cloud, our solution addresses privacy and security concerns while maintaining usability.
In the case of mismanagement, organizations can suffer from data breaches and leakage.
Exposing corporate resources without implementing proper security places the company at risk of compromise.
Ayad proposed an efficient and privacy-preserving approximate search in cloud computing .
With the value of multiple clouds and platforms within the enterprise comes new cybersecurity challenges, making it imperative to securely manage infrastructure and resources ahead of advanced threats.
Cloud infrastructures that remain misconfigured by enterprises or even cloud providers can lead to several vulnerabilities that significantly increase an organization’s attack surface. CSPM addresses these issues by helping to organize and deploy the core components of cloud security. These include identity and access management (IAM), regulatory compliance management, traffic monitoring, threat response, risk mitigation, and digital asset management.
Digital twin and its medical applications
Index 1 allows querying the total number of medical records for a user via their ID. To retrieve a specific encrypted medical record, the user simply provides the record’s ID to fetch it from the cloud. If the user wants to exchange plaintext records with another user, they need to exchange decryption keys. We propose a cloud retrieval method based on searchable encryption to enable secure searches on encrypted data. Searchable encryption allows searches to be performed on encrypted data without decrypting it first. Many files stored on remote servers need to be deleted or modified by the server.
Cost savings tops the list for local companies, suggesting a further correlation to cloud security maturity levels. Interestingly, in the global survey, the misconfiguration of cloud platforms is cited as the number one threat in the public cloud at 59%, while in SA, the same issue ranks 4th at 39.8%. This suggests that in SA there’s a greater focus on basic security risks, such as preventing common cyberattacks, while the more mature market has moved beyond that risk level.
Security issues associated with the cloud
It’s not too late to introduce Bring Your Own Key (BYOK) encryption for the overall benefit of the organization and customers. The cloud environment is dramatically expanding, and the identification of misconfiguration becomes increasingly difficult. Now that we’ve explored the main advantages and disadvantages of each cloud security vendor, see how their service offerings stack up against one another. Palo Alto Network Prisma Cloud and Prisma Cloud Compute include Compliance & Governance (CSPM), Workload (CWPP). Prisma Access and Prisma SaaS include secure Internet access for branches and users, WAAP.
These new times also introduce opportunities for new companies born in the cloud to base everything on the cloud. This includes the need to adopt DevOps and DevSecOps for both pure cloud-native companies and hybrid ones with both cloud-based and on-prem infrastructure. Companies are increasingly moving from traditional, on-premises configuration control boards data centers to cloud-based deployments. The cloud provides a variety of benefits, such as increased scalability, flexibility, and cost savings. This shift to the cloud is also driven by the increased popularity of hybrid work models, as the cloud offers better performance and accessibility for on-site and remote workers alike.

The rise of ubiquitous sensors, high-speed networks and cloud infrastructure has enabled digital twins to scale across entire cities and countries. National digital twin initiatives aim to digitally map infrastructure, buildings and natural systems for urban planning, emergency response simulation and sustainability goals . Electronic medical records (EMRs) serve as a digital version of traditional case histories, encompassing the complete medical and health records of patients. EMRs are stored, managed, transmitted, and reproduced electronically, replacing the conventional method of handwritten paper records .
Key generation and key exchange method
(2) The doctor decrypts the ciphertext using their private key to obtain the three encryption keys and patient’s personal information. To query prescriptions for a disease, the user searches Index 2 by disease keywords to get the corresponding symptom and prescription locations in the cloud. The user then downloads the encrypted symptoms and prescriptions from the cloud and requests access rights from the owners.
Cloud security spending for 2023 is on track to climb 25.2 percent to $5.61 billion, year-over-year, before growing another 24.7 percent in 2024 to reach $7 billion, the research firm reported. As cloud security threats surge, a broad array of new tools from both industry giants and fast-growing startups have been released in recent months. The continuous advancement in Artificial Intelligence and Machine learning requires businesses to rethink their security techniques. These technical advancements offer complete protection of the data, thereby saving businesses from severe cyber thefts. It’s crucial as undetected thefts could cause severe damages that take time to recover. Attribute-based encryption is a type of public-key encryption in which the secret key of a user and the ciphertext are dependent upon attributes (e.g. the country in which he lives, or the kind of subscription he has).
