Clop Ransomware in Action: A Comprehensive Analysis of Its Multi-Stage Tactics

Recently, Clop ransomware attacks targeting non-IT fields such as distribution, logistics, and manufacturing have been rapidly increasing. These advanced attacks are particularly concentrated on Active Directory (AD) servers, causing significant operational and financial disruption to the affected organizations. In this study, the multi-step behavior of Clop ransomware was deeply investigated to decipher the sequential techniques and strategies of attackers. One of the key insights uncovered is the vulnerability in AD administrator accounts, which are often used as a primary point of exploitation. This study aims to provide a comprehensive analysis that enables organizations to develop a deeper understanding of the multifaceted threats posed by Clop ransomware and to build more strategic and robust defenses against them.

Supporting caregivers of people with dementia: insights from Demensia KITA mobile application online content development

Dementia significantly impacts caregivers, particularly in low and middle-income countries where support is often inadequate. Given the gap in affordable and culturally relevant digital resources for Malaysian dementia caregivers, we developed "Demensia KITA," a mobile application (app) specifically tailored to their needs. This study utilized a theoretical framework proposed from existing literature and the "Model of Carer Stress and Burden". This paper discusses our app content development, highlighting key findings and challenges. To assess caregivers’ needs, the Nominal Group Technique (NGT) with five dementia caregivers was conducted, followed by a Focus Group Discussion (FGD) with eight medical professionals. Both sessions were conducted online via Google Meet. In the NGT, ideas were generated, organized, prioritized, reviewed, and refined by medical professionals in the FGD. Content relevant to addressing the complexities of dementia caregiving was then discussed. Topics were either adapted from established modules or newly developed from credible sources. Subsequently, these were organized into modules and themes, and subsequently underwent expert validation. From the NGT, three key domains emerged: Knowledge, Services, and Support. These were further organized into two modules: 'Patient Care for Caregivers' and 'Caregiver Wellbeing'. Within these, twelve sub-modules were identified, covering a range of topics including basic knowledge on dementia, patient care, nutritional management, oral and dental care, simple exercises, daily activity and memory rehabilitation, service directories, support groups, emotional and stress management, welfare assistance, and daily motivation. This framework was developed to address the specific needs of dementia caregivers in terms of psychoeducation, psychosocial and caregiving skills, incorporating expert opinions in the field. This study corroborates the feasibility of online methods for mobile health app content development and encourages similar research. Future studies should evaluate Demensia KITA's effectiveness in alleviating caregiver burden across all regions, assess users’ acceptance, and ensure it meets the evolving needs of Malaysian caregivers with regular updates.

AGCN-Domain: Detecting Malicious Domains with Graph Convolutional Network and Attention Mechanism

Domain Name System (DNS) plays an infrastructure role in providing the directory service for mapping domains to IPs on the Internet. Considering the foundation and openness of DNS, it is not surprising that adversaries register massive domains to enable multiple malicious activities, such as spam, command and control (C&C), malware distribution, click fraud, etc. Therefore, detecting malicious domains is a significant topic in security research. Although a substantial quantity of research has been conducted, previous work has failed to fuse multiple relationship features to uncover the deep underlying relationships between domains, thus largely limiting their level of performance. In this paper, we proposed AGCN-Domain to detect malicious domains by combining various relations. The core concept behind our work is to analyze relations between domains according to their behaviors in multiple perspectives and fuse them intelligently. The AGCN-Domain model utilizes three relationships (client relation, resolution relation, and cname relation) to construct three relationship feature graphs to extract features and intelligently fuse the features extracted from the graphs through an attention mechanism. After the relationship features are extracted from the domain names, they are put into the trained classifier to be processed. Through our experiments, we have demonstrated the performance of our proposed AGCN-Domain model. With 10% initialized labels in the dataset, our AGCN-Domain model achieved an accuracy of 94.27% and the F1 score of 87.93%, significantly outperforming other methods in the comparative experiments.

Stakeholder engagement to develop a directory of COVID-19 related mental health services in Vietnam: reflections on a participatory approach.

The COVID-19 pandemic led to a rise of mental health issues amongst Vietnamese communities in Vietnam and the diaspora. However, there were few resources and no directory of services available for people seeking mental health support in Vietnam. In response to this need, we initiated an engagement project to improve Vietnamese communities' access to mental health support. This project aimed to involve stakeholders in the development of a directory of resources in order to ensure that it met local needs. The phases of development included: (1) reviewing desk research findings; (2) reviewing the list of mental health support services that we could find; (3) verifying the first draft of the directory; (4) helping disseminate the directory; and (5) updating the directory. In February 2022 the first edition of the mental health directory for Vietnamese and foreigners living in Vietnam was published. In this paper we describe the iterative approach taken to developing a resource that would have maximum utility for the target communities. We describe the process of partnering with people with lived experience, community members and expert stakeholders in this process, and reflect on how this strengthened the outcomes in terms of the relevance of the output, the research uptake and the access for the wider community. We believe that it is important to publish examples of community engagement projects in order to demonstrate good practise and promote increased involvement of communities in research.

Developing primary care services for stroke survivors: the Improving Primary Care After Stroke (IPCAS) research programme

Background It is recognised that longer-term needs after stroke may not be well addressed by current services. The aim of this programme of research was to develop a novel primary care model to address these needs and to evaluate this new approach. Objectives The work was divided into three workstreams: development of a primary care model development of a ‘Managing Life After Stroke’ programme (including self-management) for people with stroke evaluation of the effectiveness and cost effectiveness of these interventions. Design The development of the primary care model involved information gathering in the form of literature reviews, patient and public involvement workshops, qualitative studies (interviews and focus groups), a consensus study and a pilot study, all feeding into a multidisciplinary intervention development group that approved the final primary care model. In parallel, a further literature review, consultation workshops with healthcare professionals and patients and public involvement fed into the iterative development of the ‘My Life After Stroke’ programme. In the final phase of the programme, the two interventions were evaluated in a cluster randomised controlled trial, which included a process evaluation and within-trial cost-effectiveness analysis. Setting General practices in the East of England and East Midlands. Participants People with a history of stroke identified from general practice stroke registers. Interventions The Improving Primary Care After Stroke model of primary care delivery. This comprised five components: a structured review; a direct point of contact; improving communication between primary and secondary care; local service mapping; and training of primary care professionals. The ‘My Life After Stroke’ self-management programme for people with stroke comprised an initial individual session, four weekly group-based sessions and a final individual session. Main outcome measures The coprimary end points for the trial were two subscales (emotion and participation) of the Stroke Impact Scale v3.0 at 12 months after randomisation. Secondary outcomes included the Stroke Impact Scale Short Form, the EuroQol-5 Dimension, five level questionnaire, the ICEpop CAPability measure for Adults, the Southampton Stroke Self-Management Questionnaire and the Health Literacy Questionnaire. Data sources General practice records for health economic costing data. Patient questionnaires for outcomes. Results Trial: 46 clusters (general practices) were randomised with 1040 participants. At 12 months, there was a 0.64 (97.5% confidence interval −1.7 to +2.8) improvement in the emotion outcome in the intervention arm compared to the control arm and a 1.3 (97.5% confidence interval −2.0 to +4.6) increase in the participation outcome in the intervention arm compared to control. There was also no evidence of effect of the intervention on short form Stroke Impact Scale, quality of life (EuroQol 5 Dimension 5 level questionnaire), well-being (ICEpop CAPability measure for Adults), Southampton Stroke Self-Management questionnaire or health literacy (Health Literacy Questionnaire). Process evaluation: over 80% of participants received a review. Only a third of patients attended the ‘My Life After Stroke’ course. The direct point of contact service was hardly used. The local directory of services had variable take-up by healthcare professionals. It did not prove possible to support improved communication between primary and secondary care as originally intended. Training fidelity was high. Cost-effectiveness analysis: the intervention increased primary care workload and was associated with a non-significant, higher quality-adjusted life-year at 12 months. The incremental cost per quality-adjusted life-year was £20,863. Limitations There were differences in age, sex and proportion of people from minority ethnic groups in the trial population as compared to a typical general practice stroke register. Uptake of the intervention was variable. Ceiling effects were observed in the primary outcome measure. Follow-up was limited to 12 months. Conclusions This programme of research has reaffirmed the importance of addressing longer-term needs of people after stroke in the community. The most commonly expressed need is fatigue. The primary care model that we developed was not effective at addressing these needs. Our qualitative findings suggest that an intervention focused on patients earlier after their stroke or one which is more intensive might be effective. There was a mismatch between the needs reported by stroke survivors and evidence available for how to address these needs. Future work Research to inform who should be offered poststroke assessment of needs in the community in the longer term (after 6 months). Development and evaluation of interventions to address fatigue, low mood and cognitive problems in people with stroke in the community.

A content analysis of the interventions for low back pain promoted on the websites of Australian pain clinics.

The Internet is a widely used source of health information, yet the accuracy of online information can be low. This is the case for low back pain (LBP), where much of the information about LBP treatment is poor. This research conducted a content analysis to explore what pain treatments for LBP are presented to the public on websites of Australian pain clinics listed in the PainAustralia National Pain Services Directory. Websites providing information relevant to the treatment of LBP were included. Details of the treatments for LBP offered by each pain service were extracted. In total, 173 pain services were included, with these services linking to 100 unique websites. Services were predominantly under private ownership and located in urban areas, with limited services in non-urban locations. Websites provided detail on a median of six (IQR 3-8) treatments, with detail on a higher number of treatments provided by services in the private sector. Physical, psychological and educational treatments were offered by the majority of pain services, whereas surgical and workplace-focused treatments were offered by relatively few services. Most services provided details on multidisciplinary care; however, interdisciplinary, coordinated care characterised by case-conferencing was infrequently mentioned. Most websites provided details on treatments that were largely in-line with recommended care for LBP, but some were not, especially in private clinics. However, whether the information provided online is a true reflection of the services offered in clinics remains to be investigated.

Spatial clusters of potentially preventable hospitalisations and access to allied health services in South Western Sydney: a geospatial study.

ObjectiveTo explore the association between geographic access to allied health services and potentially preventable hospitalisations.MethodsThis is a retrospective observational study. Adults aged 18years or older with a potentially preventable hospitalisation for a chronic condition(s) to a public hospital in South Western Sydney Local Health District between 1 July 2016 and 30 June 2019 were identified from the Secure Analytic for Population Health and Intelligence portal at NSW Health. Locations of allied health amenities or practices in the same geographic area were identified from the 2019 National Health Service Directory. Geospatial analysis was used to identify geographic hotspots and coldspots of potentially preventable hospitalisations. Association with access to allied health services was investigated using linear models.ResultsHotspots of potentially preventable hospitalisations were significantly more disadvantaged than coldspots. Hotspots also had poorer access to allied health services than coldspots.ConclusionIn South Western Sydney, populations with higher burden of chronic disease, as measured through preventable hospitalisations, have poorer access to allied health services than populations with lesser need.

Health Services for Young Adults with Stroke: A Service Mapping Study over Two Australian States

Despite increased incidence of stroke in young adulthood across the world, young adults report significant difficulties finding services with the expertise and experience to meet their needs. This service mapping study sought to identify and characterise the availability, accessibility, and accommodation of services to meet the needs of young adults (aged 18–44 years) with stroke in two Australian states. Methods. Relevant clinical, rehabilitation, and allied health services were systematically identified from previous publications; the National Health Service Directory; professional association “find a provider” listings; and Stroke Foundation service lists. Desktop audit (n = 465 services) and key informant interviews (n = 321 services) were used to collect service design and delivery characteristics; level of experience, confidence, and willingness to work with young adults with stroke; and accommodation of communication impairments. Results. Most services (85%) were in major cities or inner regional areas. No services worked solely with young adults with stroke; however, several reported having relevant expertise, training, experience, and programmes to provide neurological rehabilitation to meet the needs of young adults with stroke. Reported willingness (91.0%) to work with young adults with stroke was high, but only 57.0% were very confident to do so. Most services with neurorehabilitation expertise addressed psychosocial recovery needs (e.g., emotional adjustment and relationships) as well as functional recovery, but few supported return‐to‐driving, peer support, and sensory processing disturbances. Further gaps were the use of accessible communication materials in only 50.2% of services, and staff had completed communication training at only 60.4% of services. Conclusion. Findings highlight that while expert neurorehabilitation services exist, they are not sufficiently available, accessible, or accommodating of the needs of young adults with stroke. There remains a need to improve access to services where clinicians have the skills to meet the rehabilitation needs of young adults with stroke in Australia.

Strategies for integrating the Making Every Contact programme for the prevention and management of chronic disease across Irish Health Service

Introduction: The Irish Health Service Executive (HSE) Making Every Contact Count (MECC) Programme1 aims to integrate lifestyle behaviour interventions by health professionals to patients targeting health behavioural risk factors (e.g. physical activity, diet, smoking and drug and alcohol use. The MECC programme (implemented since 2019) is a key element of the Integrated care programme for the prevention and management of Chronic disease in Ireland (ICP CD)2 . I will present recent research which has identified key strategies for upscaling implementation and integrating brief interventions in the Irish Health Service.
 Aim, Objectives, Theory or Methods: The research team worked collaboratively to develop an evidence-based implementation strategy to optimise and scale up MECC. The implementation strategy was informed by three studies:
 1.Study 1: Survey study of 357 healthcare professionals who had completed MECC e-Learning training to determine barriers and enablers to MECC intervention delivery.
 2.Study 2: Qualitative interview study with 36 healthcare professionals and those involved in MECC implementation to understand the individual and organisational level enablers and barriers to the implementation of MECC.
 3.Study 3: Consensus study to achieve stakeholder consensus on strategies to address identified barriers and enablers .
 
 Highlights or Results or Key Findings: Using the Theoretical Domains Framework3 barriers and enablers to Implementation were identified under the following domains: environmental context, goals and intentions, knowledge, professional role, beliefs about consequences, beliefs about capabilities and skills practice. 
 A consensus process identified and refined the following nine implementation strategies.
 1.Provide dedicated time to practitioners to attend training and use MECC
 2.Empower and engage management/senior staff to take responsibility for MECC
 3.Implement a user-friendly and integrated system of recording MECC
 4.Develop service directories for healthcare professionals to refer patients
 5.Have local MECC champions to model best practice and share experiences
 6.Create a dedicated resource centre on the MECC website with information regarding MECC training courses and contacts
 7.Have a HSE national communications campaign to promote MECC
 8.Generate and highlight evidence for the impact of MECC on patients
 9.Enhance integration of MECC with undergraduate healthcare professional education
 Conclusion: In this programme of research we have worked with key stakeholders to understand barriers and enablers to MECC implementation and develop recommendations to enhance the implementation and scaling-up of the MECC programme.
 Implementation of the MECC programme remains a key priority for the Irish Health Service. 
 Implications for applicability/transferability, sustainability, and limitations: The outputs from this research provide strong evidence based strategies to support the ongoing implementation of the MECC programme. The dissemination of the findings to key policy and strategic stakeholders and the development of an implementation plan will further embed Making Every Contact Count in services.
 

Information technologies of application architecture`s IT services

The development of the System Architecture of the IT infrastructure focused on the usage of modern Data Centers is considered. The purpose of the research is to develop a strategy for the development of the System Architecture of the IT infrastructure based on the usage of advanced methodologies and concepts of leading manufacturer’s hardware and software. The following principle of IT infrastructure construction is formulated: IT infrastructure architectures define a set of services. IT services are provided to three groups of clients. IT services and clients are connected by 5 implementation scenarios. The integration of IT services is determined by 5 architectures. As IT services, we understand information technologies aimed at maintaining the following elements in technically good condition: network devices, computing equipment, data storage devices, automatic software deployment services, network services, perimeter protection services, directory services, file and print services, data management services, business application services, IT management services, archiving and recovery services, certificate management services, integration services. Architectures define the fundamental principles of building IT services and their relationship. One of the most important architectures is the architecture of software applications. The architecture of software applications is determined by the business needs of the corporation and the approaches, methods of creating applications by a specific developer. It defines the execution environment for applications, mechanisms of communication between applications and components, tools for controlling the application and managing its state, as well as storage for structured and unstructured data types. Tasks of the architecture: to provide an environment for the execution of application components; support dispatching mechanisms for communications between application components; implement tools for monitoring the level of services and diagnosing problems; provide storage of structured and unstructured information. Standardization of the application architecture allows you to minimize costs associated with the support of several types of architectures, each for a specific type of business application.

World human neutrophil antigens investigation survey.

Human neutrophil antigens (HNAs) are categorized into five systems: HNA-1 to HNA-5. Given the importance of neutrophils in immunity, we sought to create awareness of the role of HNA diagnostic services in managing immune neutropenia and transfusion-related acute lung injury. To provide health communities all around the world with access to these services, we conducted a survey to create a directory of these HNA diagnostic services. An Excel table-based survey was created to capture information on the laboratory's location and was emailed to 55 individuals with known or possible HNA investigation activity. The collected data were then summarized and analysed. Of contacted laboratories, the surveys were returned from 23 (38.2%) laboratories; 17 have already established HNA diagnostic (of them 12 were regular participants of the International Granulocyte Immunobiology Workshop [ISBT-IGIW]), 4 laboratories were in the process of establishing their HNA investigation and the remaining 2 responder laboratories, did not conduct HNA investigations. In established laboratories, investigation for autoimmune neutropenia (infancies and adults) was the most frequently requested, and antibodies against HNA-1a and HNA-1b were the most commonly detected. The directory of survey respondents provides a resource for health professionals wanting to access HNA diagnostic services. The present study offers a comprehensive picture of HNA diagnostics (typing and serology), identifying weak points and areas for improvement for the first time. Identifying more laboratories involved in HNA diagnostics with limited access to international societies in the field will globally improve HNA diagnostics.

Volunteers as a resource for asset mapping and maintaining a living resource directory: lessons from an academic-community partnership.

Health and social services are fundamental to public and population health, and disruptions can have devastating effects on individuals of all ages. During the first wave of the COVID-19 pandemic, the availability of health and social services rapidly changed. Existing resources experienced changes in operation and mode of service delivery, while new resources emerged to address escalating needs. Both the general public and service providers lacked access to accurate information on availability and access, and existing service directories became obsolete or unreliable. To address this gap, a committee of university students expanded its volunteer base, partnered with a local non-profit organization, and invested in maintaining a centralized, up-to-date resource directory for the region. Student volunteers sourced and consolidated existing county-level directories to curate more than 370 resources across 12 healthcare and social care domains in a Google Sheets platform. This directory was publicly accessible, available in English and Spanish, adjustable to community feedback and needs, disseminated through the local health system intranet, synthesized into paper handouts for food pantries, and utilized to curate a directory aimed toward older adult needs. Students worked in a tiered leadership model and mobilized quickly to respond to immediate community needs. This academic-community partnership engaging student volunteers can be a low-cost, high-value resource to support public health systems meet the information needs of their community, particularly during periods of crisis or rapid changes in service availability.

E045 Clinical triage: Investing in the front door

Abstract Background/Aims The processes and IT systems that support the referral pathway are complex. The focus on referral optimisation and out-patient transformation has provided an opportunity to do things differently. Getting It Right First Time recommendations highlight the importance of ensuring rheumatologists focus on conditions which require specialist rheumatology input. As part of an integrated musculoskeletal (MSK) service we are able to redirect referrals regarding non-inflammatory conditions to our MSK and Community Pain teams. This project evaluates the impact of clinical triage. Methods Consultant-led triage introduced in July 2021. Directory of services updated and met with primary care networks leads to inform them of the changes. Letter co-designed with GPs to send out to patients when referral responded to with immediate specialist advice. Triage job planned with an allocation of 45 minutes per day. Referrals are reviewed on the electronic referral system and accepted, returned or redirected to another service. Standard responses developed to ensure consistency. All triage outcomes recorded in a spreadsheet. Review undertaken of returned referrals to identify any patients who were re-referred. To ascertain the proportion of patients triaged to early inflammatory arthritis (EIA) appointments who were diagnosed with an EIA, National Early Inflammatory Arthritis Audit data was analysed before and after changes to triage. Results Between January and June 2022 we received 1194 referrals; 761 (64%) were accepted, 289 (24%) returned, 43 (4%) redirected to another service and 73 (6%) returned with immediate specialist advice. Of the 289 referrals that were returned, 74 (25%) were returned for more information, 61 (21%) with a request to examine the patient, 118 (41%) were deemed inappropriate, 14 (4%) were patients already under our care and 22 (8%) were returned for other reasons. We received a further referral for 46/74 of those returned for more information, 45/61 following the request to examine the patient, 13/118 of those returned as not felt appropriate and 3/73 of those returned with immediate specialist advice. In total, we saved 278 new patient appointments over a 6-month period. Allowing for the time job planned, this was a net gain of 6 new patient appointments a week. In 2019, 37% of patients seen in an EIA appointment were diagnosed with an EIA compared to 51% in 2022. Conclusion Investment in clinical triage has saved a considerable number of appointments. For some patients it has provided an immediate specialist opinion or redirected them to a more appropriate service. It has helped to ensure that we are seeing patients who require specialist rheumatology input. Next steps are to share this work more widely and develop resources for patients and primary care to help promote a different way of working and delivering specialist advice. Disclosure E.

Prevalence of Diversity Statements and Disability Inclusion Among Radiology Residency Program Websites

IntroductionRadiology has widely acknowledged the need to improve inclusion of racial, ethnic, gender, and sexual minorities, with recent discourse also underscoring the importance of disability diversity and inclusion efforts. Yet studies have shown a paucity of diversity among radiology residents, despite increasing efforts to foster diversity and inclusion. Thus, the purpose of this study is to assess radiology residency program websites’ diversity statements for inclusion of race and ethnicity, gender, sexual orientation, and disability as commonly underrepresented groups. MethodsA cross-sectional, observational study of websites of all diagnostic radiology programs in the Electronic Residency Application Service directory was conducted. Program websites that met inclusion criteria were audited for presence of a diversity statement; if the statement was specific to the residency program, radiology department, or institution; and if it was presented or linked on the program or department website. All statements were evaluated for the inclusion of four diversity categories: race or ethnicity, gender, sexual orientation, and disability. ResultsOne hundred ninety-two radiology residencies were identified using Electronic Residency Application Service. Programs with missing or malfunctioning hyperlinks (n = 33) or required logins (n = 1) were excluded. One hundred fifty-eight websites met inclusion criteria for analysis. Two-thirds (n = 103; 65.1%) had a diversity statement within their residency, department, or institution, with only 28 (18%) having residency program–specific statements and 22 (14%) having department-specific statements. Of the websites with diversity statements, inclusion of gender diversity was most frequent (43.0%), followed by race or ethnicity (39.9%), sexual orientation (32.9%), and disability (25.3%). Race or ethnicity was most included in institution-level diversity statements. ConclusionsLess than 20% of radiology residency websites include a diversity statement, and disability is the least-included category among the diversity statements. As radiology continues to lead diversity and inclusion efforts in health care, a more comprehensive approach with equitable representation of different groups, including those with disabilities, would foster a broader sense of belonging. This comprehensive approach can help to overcome systemic barriers and bridge gaps in disability representation.

RESTful API Analysis, Recommendation, and Client Code Retrieval

Numerous companies create innovative software systems using Web APIs (Application Programming Interfaces). API search engines and API directory services, such as ProgrammableWeb, Rapid API Hub, APIs.guru, and API Harmony, have been developed to facilitate the utilization of various APIs. Unfortunately, most API systems provide only superficial support, with no assistance in obtaining relevant APIs or examples of code usage. To better realize the “FAIR” (Findability, Accessibility, Interoperability, and Reusability) features for the usage of Web APIs, in this study, we developed an API inspection system (referred to as API Prober) to provide a new API directory service with multiple supplemental functionalities. To facilitate the findability and accessibility of APIs, API Prober transforms OAS (OpenAPI Specifications) into a graph structure and automatically annotates the semantic concepts using LDA (Latent Dirichlet Allocation) and WordNet. To enhance interoperability, API Prober also classifies APIs by clustering OAS documents and recommends alternative services to be substituted or merged with the target service. Finally, to support reusability, API Prober makes it possible to retrieve examples of API utilization code in Java by parsing source code in GitHub. The experimental results demonstrate the effectiveness of the API Prober in recommending relevant services and providing usage examples based on real-world client code. This research contributes to providing viable methods to appropriately analyze and cluster Web APIs, and recommend APIs and client code examples.

Review Paper on the Light Weight Directory Access Protocol

External LDAP directories currently use directory servers such as MS Active Directory, OpenLDAP, OpenDJ, etc. to store user, group, and authorization information and then provide that information organization's enterprise applications. This is considered a standard technique. Most organizations prefer external LDAP because the authentication protocol is very simple. The proposed system uses an external Lightweight Directory Access Protocol (LDAP) to manage and authenticate user information inside and outside the organization. This external LDAP directory stores various user information. This information can be later retrieved by other users, depending on their access level. Various applications also use this technology to ensure that authenticated users provide correct authentication data. This data must match the information stored on your LDAP server.

Implementation of the elements of the enterprise protection system

The article defines the main tasks and features of corporate information networks and analyzes the specifics of the corporate network implemented in a medical center. The proposed data protection system at the enterprise is developed on the basis of the Bella-La Padula model since the key provisions of this model are the assignment of special security levels to all participants in the protected data processing process and to the documents in which it is contained. The specified security levels are arranged using the established dominance relationship, and the access control is carried out depending on the security levels of the interacting parties, which allows the application of technical solutions of the Active Directory service. One of the elements to ensure data protection is the use of a Shadow Copy of data according to the appropriate schedule. An important component of ensuring data protection is the individual process of setting up group policies and checking replication with other servers running the Active Directory directory services of the medical center. As a result of the implementation of elements of the company's data protection system, it was possible to significantly increase the level of protection and set up a backup server, on which appropriate folders were created, to which backup copies would be made according to the schedule. This function makes it possible to save the history of changes in any file for a certain period. The proposed elements of the security system can be used to analyze the security system, control access, ensure data integrity, etc. The Active Directory directory services were implemented in the medical center, and data replication to a backup server was configured. Taking into account the specifics of the enterprise, namely the medical center, the implemented elements of the data protection system ensure the delimitation of access levels, implement protection profiles and secure the personal data of patients.

Information technology of IT-infrastructure management architecture elements

The development of the System Architecture of the IT-infrastructure focused on the use of modern Data Centers is considered. At the same time, it is envisaged to create components that describe: general approaches to building a system architecture; IT-services – information technologies that solve the task of providing IT-services; logical model of IT-infrastructure. Formulated logic of IT-infrastructure construction: IT-infrastructure architectures define a set of services. IT-services are provided to three groups of clients. IT-services and clients are connected by 5 implementation scenarios. The integration of IT-services is determined by 5 architectures. As IT-services, we understand information technologies aimed at maintaining the following elements in a technically good state: network devices, computing equipment, data storage devices, automatic software deployment services, network services, perimeter protection services, directory services, file and print services, data management services, business application services, IT-management services, archiving and recovery services, certificate management services, integration services. Architectures define the fundamental principles of building IT-services and their relationship. Also, requirements for the creation of IT-services are formed on the basis of the architecture. One of the most important architectures is architecture of IT-infrastructure management. The architecture of the management system ensures the necessary level of IT-services of the Data Center due to the organization of three components – personnel, processes, technologies. The tasks of the architecture are: use of processes and information technologies to identify and minimize failures of IT-services; ensuring a high degree of integration of information technologies; ensuring response to changes in system parameters and performance of service functions in real time. As an example, the management function of the IT-service “network administration” (monitoring and control of configuration management services, coordination of changes, remote management and debugging) is considered. The algorithmic synthesis of programs and devices network management is considered, which consists in the construction of a functional scheme of control devices in two stages – abstract and structural synthesis, and all the steps of its solution and subsequent hardware synthesis are determined.

EGS P19 A new normal or the calm before the storm?

Abstract Background One of the highest risk factors for morbidity and mortality for general surgery patients is having their surgery in the emergent rather than elective setting. Patients are presenting older, with often complex pathology on a background of multiple medical comorbidities and sometimes extensive surgical history. NELA (national emergency laparotomy audit) and similar projects have looked at assessing and improving upon the management of such cases. These have produced valuable data and improvement in outcomes but there remains a lack of information around the acuity of surgery and the provision of services in response to demand. This study sought to assess the number of NELA cases in hospitals around the UK and compare this to historical data pre-pandemic. Methods Acute trusts admitting adults under general surgery in England were identified from the online NHS Service Directory. This list was cross referenced with the National Emergency Laparotomy Audit (NELA) list of participating hospitals to check for completeness. This generated 123 acute trusts in England. Contact details for each trust's Freedom of Information (FOI) department was identified from publicly available data on each trust's website. Questions were submitted to the FOI via email for 112 trusts, and online form submission for 11 trusts. Responses were collected for 8 weeks from the date of submission and analysed in Microsoft Excel. Trusts were asked to provide the number of general surgery admissions, inpatient bed numbers and NELA numbers. These were cross-referenced with publicly available data from NHS and NELA websites. Comparisons were made to similar data from 2014. Results 101 out of 124 trusts responded within the 8-week timeframe. 14,497 NELA cases were recorded from the national total of 21,846 stated in the NELA Year 7 report (66.36%). The mean number of beds reported per NELA case was 5.76 (+/- 1.46 CI 95%), with histogram peaking between 3 and 5 beds with a right skew distribution. The mean number of admissions per NELA case was 30.81 (+/- 3.29 CI 95%), with histogram data peaking between 21 and 26 admissions with right skew distribution. A comparison with data from 2014 can be seen below (table 1). Conclusions The Covid-19 pandemic had significant and widespread effects on the provision of services but also to demand. We now know that presentations to hospital reduced as did subsequent inpatient admissions. Our study shows that the number of NELA cases decreased across England and this was independent of hospital size. The largest decrease was seen in quartile 2 followed by quartile 3 representing mid-sized hospitals. Whilst not certain it is likely that this decrease was secondary to the pandemic rather than any change in practices. The results from this study can be used to help hospitals and departments plan their provision of services and training.
