Abstract:Empowered by virtualization technology, service requests from cloud users can be honored through creating and running virtual machines. Virtual machines established for different users may be allocated to the same physical server, making the cloud vulnerable to coresidence attacks where a malicious attacker can steal a user's data through co-residing their virtual machines on the same server. For protecting data against the theft, the data partition technique is applied to divide the user's data into multiple … Show more
“…Generally, in the case of a large IP packet, it will be splitted into numerous fragments and reassembled into a complete packet to the recipient host. However, POD attack exactly exploits the reassembling packet size of 65,535 bytes greater than its maximum to maliciously manipulate overflow of memory allocated as a result of denial of service [11].…”

“…CCA could be conducted by various methods such as structured query language (SQL) injection attack, DDoS attack, malicious insider, side channel attack, man-in-themiddle (MITM) attack and abuse of cloud services. Cloud computing attack is the most economically significant threat in the world of virtualization technology, confidential data breach is one of the key diminish potential revenue loss and customer trust [11]. In fact, a massive cyber attack in Sweden in July 2017, a high confidential data stored at cloud system was breached, causing irreversible consequences that exposed national secrets, national security, international wrongdoing, and resignation of ministers.…”

Over the decades, the forms of cyber-attacks have evolved from disruption level, cybercriminal, followed by cyber espionage and lastly threatening level. Digital security has played a significant role in protecting enterprises from any form of cyber-attacks, especially in today's era of digitalization. Aligning with the global effort in emerging the concept of Industrial Revolution 4.0 (IR4.0) in organizations, where sensitive data and confidential information can be accessed at a fingertip of an employee. This paper discusses the difficulties of implementing digital security solutions in an enterprise in terms of external potential cyber threats, internal cyber security roadblocks within the organization and how Covid-19 pandemic imposed challenges towards cyber security in the organizations.

“…Prevention and detection methods as well as professionally trained cybersecurity specialists are needed to protect patient data, medical devices and other sensitive healthcare systems. [1,7,8,9,11,15,19,25,27,29,31,33,35,36,38,39,40,42,45].…”
The mandate for cybersecurity crosses disciplines. The deficit in the number of cybersecurity professionals required to fill current and future positions represents a growing challenge. Cybersecurity readiness presents significant ever-changing issues with possible long-term or perhaps life-threatening consequences. Cybersecurity experts who possess critical knowledge in another field such as healthcare where a combined or blended understanding of key information is integral to the industry are in short supply. In healthcare, as is the case in a host of other sectors, not only is it necessary that systems and data are protected, but the business must be compliant with existing law as well. It is imperative that action be taken to address the problem in order not to limit access to healthcare. The focus of this research is to study the serious shortage of cybersecurity professionals in the field of healthcare, the impact that this issue has on the availability of healthcare, and to suggest a solution that could provide immediate relief.
“…The information contained in the test sample is real-time and fair. [7][8][9][10] Second, make clear the structure of artificial neural network. In practice, the concrete model with artificial neural network as the core should be defined first.…”
Using the advantage of decision tree algorithm in the screening work, the traditional ID3 algorithm is improved and optimized, and a new and simplified financial index system is constructed. At the same time, combined with the unique value of artificial neural network in early warning model and data analysis, B-P model is used to build a mixed financial early warning model. In the model study, the HFPM model and Z-score model were compared and analyzed by using test samples and training samples, and the superior warning ability of the former was effectively verified.
