Computer network protocols define the rules in which two entities communicate over a network of unique hosts. Many protocol specifications are unknown, unavailable, or minimally documented, which prevents thorough analysis of the protocol for security purposes. For example, modern botnets often use undocumented and unique application-layer communication protocols to maintain command and control over numerous distributed hosts. Inferring the specification of closed protocols has numerous advantages, such as intelligent deep packet inspection, enhanced intrusion detection system algorithms for communications, and integration with legacy software packages. The multitude of closed protocols coupled with existing time-intensive reverse engineering methodologies has spawned investigation into automated approaches for reverse engineering of closed protocols. This article summarizes and organizes previously presented automatic protocol reverse engineering tools by approach. Approaches that focus on reverse engineering the finite state machine of a target protocol are separated from those that focus on reverse engineering the protocol format.

In November 1970 Black Panther Party leader Huey P. Newton gave a lecture at Boston College where he introduced his theory of intercommunalism. Newton re-articulated Marxist theories of imperialism through the lens of the Black liberation struggle and argued that imperialism had entered a new phase called 'reactionary intercommunalism'. Newton's theory of intercommunalism offers nothing less than a proto-theorization of what we have come to call neo-liberal globalization and its effects on what W.E.B. Du Bois had seen as the racialization of modern imperialism. Due to the initial historical dismissal of the Black Panther Party's political legacy, Newton's thought has largely been neglected for the past forty years. This paper revisits Newton's theory of intercommunalism, with the aim of achieving some form of epistemic justice for his thought, but also to highlight how Newton's recasting of imperialism as reactionary intercommunalism provides critical insight into the rise of Trumpism in the US.

What is the relationship between Brexit and biomedicine? Here we investigate the Vote Leave official campaign slogan ‘We send the EU £350 million a week. Let’s fund our NHS instead’ in order to shed new light on the nationalist stakes of Brexit. We argue that the Brexit referendum campaign must be situated within biomedical policy and practice in Britain. We propose a re-thinking of Brexit through a cultural politics of heredity to capture how biomedicine is structured around genetic understandings of ancestry and health, along with the forms of racial inheritance that structure the state and its welfare system. We explore this in three domains: the NHS and health tourism, data sharing policies between the NHS and the Home Office, and the NHS as an imperially resourced public service. Looking beyond the Brexit referendum campaign, we argue for renewed sociological attention to the relationships between racism, biology, health and inheritance in British society.

The history of the US Black Power movement and its constituent groups such as the Black Panther Party has recently gone through a process of historical reappraisal, which challenges the characterization of Black Power as the violent, misogynist and negative counterpart to the Civil Rights movement. Indeed, scholars have furthered interest in the global aspects of the movement, highlighting how Black Power was adopted in contexts as diverse as India, Israel and Polynesia. This article highlights that Britain also possessed its own distinctive form of Black Power movement, which whilst inspired and informed by its US counterpart, was also rooted in anti-colonial politics, New Commonwealth immigration and the onset of decolonization. Existing sociological narratives usually locate the prominence and visibility of British Black Power and its activism, which lasted through the 1960s to the early 1970s, within the broad history of UK race relations and the movement from anti-racism to multiculturalism. However, this characterization neglects how such Black activism conjoined explanations of domestic racism with issues of imperialism and global inequality. Through recovering this history, the article seeks to bring to the fore a forgotten part of British history and also examines how the history of British Black Power offers valuable lessons about how the politics of anti-racism and anti-imperialism should be united in the 21st century.
