‘Top 4’ strategies to mitigate targeted cyber intrusions: mandatory requirement explained

Introduction The Top 4 Strategies to Mitigate Targeted Cyber Intrusions (the Strategies) are the most effective security controls an organisation can implement at this point in time based on the our current visibility of the cyber threat environment. The Australian Signals Directorate (ASD), also known as the Defence Signals Directorate (DSD), assesses that implementing the Top 4 will mitigate at least 85% of the intrusion techniques that the Cyber Security Operations Centre (CSOC) responds to. For this reason, the Attorney‐General\u27s Department has updated the Australian Government Protective Security Policy Framework (PSPF) to require Australian government agencies to implement ICT protective security controls as detailed in the Australian Government Information Security Manual (ISM) to meet ASD\u27s Top 4 Strategies. Document scope This document provides specific implementation information on the Top 4 Strategies, including: information on the scope of and steps to manage the mandatory requirement; and some technical guidance for IT system administrators to planning and implementing the Top 4 Strategies in a typical Windows environment. This document focusses on implementing the Top 4 in a Windows environment, as the majority of government business is currently conducted using Windows operating systems. For agencies seeking implementation advice for systems that use other operating environments, ASD recommends seeking advice from your agency systems integrator or vendor in the first instance. Additionally, ASD recommends conducting research using open source publications, forums and resources available on the operating system and how each of the Top 4 could be implemented. If your agency finds it is not possible or feasible to implement the Top 4 in a non‐windows environment, you should follow appropriate risk‐management practices as outlined in the ISM

Development of grid frameworks for clinical trials and epidemiological studies

E-Health initiatives such as electronic clinical trials and epidemiological studies require access to and usage of a range of both clinical and other data sets. Such data sets are typically only available over many heterogeneous domains where a plethora of often legacy based or in-house/bespoke IT solutions exist. Considerable efforts and investments are being made across the UK to upgrade the IT infrastructures across the National Health Service (NHS) such as the National Program for IT in the NHS (NPFIT) [1]. However, it is the case that currently independent and largely non-interoperable IT solutions exist across hospitals, trusts, disease registries and GP practices – this includes security as well as more general compute and data infrastructures. Grid technology allows issues of distribution and heterogeneity to be overcome, however the clinical trials domain places special demands on security and data which hitherto the Grid community have not satisfactorily addressed. These challenges are often common across many studies and trials hence the development of a re-usable framework for creation and subsequent management of such infrastructures is highly desirable. In this paper we present the challenges in developing such a framework and outline initial scenarios and prototypes developed within the MRC funded Virtual Organisations for Trials and Epidemiological Studies (VOTES) project [2]

Ethics for Examiners

The inquisitorial bankruptcy examiner is sui generis in our system. He faces unique ethical quandaries and considerations, which require a code of ethics tailored to his role if he is to achieve fully the promise of improving Chapter 11 through the introduction of inquisitorial investigative methods. This Article attempts to point the way toward guidelines that will regulate the conduct of examiners to mitigate real, potential, and perceived abuses
