A MULTI-GIGABIT NETWORK PACKET INSPECTION AND ANALYSIS ARCHITECTURE FOR INTRUSION DETECTION AND PREVENTION UTILIZING PIPELINING AND CONTENT-ADDRESSABLE MEMORY

Increases in network traffic volume and transmission speeds have given rise to the need for extremely fast packet processing. Many traditional processor-based network devices are no longer sufficient to handle tasks such as packet analysis and intrusion detection at multi-Gigabit rates. This thesis proposes two novel pipelined hardware architectures to relieve the computational load of a processor within network switches and routers. First, the Embedded Protocol Analyzer Pre-Processor (ePAPP) is capable of taking an unclassified packet byte stream directly off of a network cable at line speed and separating the data into individually classified protocol fields. Second, the CAM-Assisted Signature-Matching Architecture (CASMA) uses ternary content-addressable memory to perform the task of stateless intrusion detection signature-matching. The Snort open-source software network intrusion detection system is used as a model for intrusion detection functionality. Structured ASIC synthesis results show that ePAPP supports speeds of 2.89 Gb/s using less than 1% of available logic cells. CASMA is shown to support 1.25 Gb/s using less than 6% of available logic cells. The CASMA architecture is demonstrated to be able to implement 1729 of 1993 or 86.8% of the attack signatures, or rules, packaged with Snort version 2.1.2

Consensus guidelines for digital scholarship in academic promotion

See: http://creativecommons.org/licenses/by/4.0/ Introduction: As scholarship moves into the digital sphere, applicant and promotion and tenure (P&T) committee members lack formal guidance on evaluating the impact of digital scholarly work. The P&T process requires the appraisal of individual scholarly impact in comparison to scholars across institutions and disciplines. As dissemination methods evolve in the digital era, we must adapt traditional P&T processes to include emerging forms of digital scholarship. Methods: We conducted a blended, expert consensus procedure using a nominal group process to create a consensus document at the Council of Emergency Medicine Residency Directors Academic Assembly on April 1, 2019. Results: We discussed consensus guidelines for evaluation and promotion of digital scholarship with the intent to develop specific, evidence-supported recommendations to P&T committees and applicants. These recommendations included the following: demonstrate scholarship criteria; provide external evidence of impact; and include digital peer-review roles. As traditional scholarship continues to evolve within the digital realm, academic medicine should adapt how that scholarship is evaluated. P&T committees in academic medicine are at the epicenter for supporting this changing paradigm in scholarship. Conclusion: P&T committees can critically appraise the quality and impact of digital scholarship using specific, validated tools. Applicants for appointment and promotion should highlight and prepare their digital scholarship to specifically address quality, impact, breadth, and relevance. It is our goal to provide specific, timely guidance for both stakeholders to recognize the value of digital scholarship in advancing our field. [West J Emerg Med. 2020;21(4)882-890.]

Consensus Guidelines for Digital Scholarship in Academic Promotion.

INTRODUCTION: As scholarship moves into the digital sphere, applicant and promotion and tenure (P&T) committee members lack formal guidance on evaluating the impact of digital scholarly work.

Guiding principles for rewilding

There has been much recent interest in the concept of rewilding as a tool for nature conservation, but also confusion over the idea, which has limited its utility. We developed a unifying definition and 10 guiding principles for rewilding through a survey of 59 rewilding experts, a summary of key organizations’ rewilding visions, and workshops involving over 100 participants from around the world. The guiding principles convey that rewilding exits on a continuum of scale, connectivity, and level of human influence and aims to restore ecosystem structure and functions to achieve a self-sustaining autonomous nature. These principles clarify the concept of rewilding and improve its effectiveness as a tool to achieve global conservation targets, including those of the UN Decade on Ecosystem Restoration and post-2020 Global Biodiversity Framework. Finally, we suggest differences in rewilding perspectives lie largely in the extent to which it is seen as achievable and in specific interventions. An understanding of the context of rewilding projects is the key to success, and careful site-specific interpretations will help achieve the aims of rewilding
