Warfighting for cyber deterrence: a strategic and moral imperative

Theories of cyber deterrence are developing rapidly. However, the literature is missing an important ingredient—warfighting for deterrence. This controversial idea, most commonly associated with nuclear strategy during the later stages of the Cold War, affords a number of advantages. It provides enhanced credibility for deterrence, offers means to deal with deterrence failure (including intrawar deterrence and damage limitation), improves compliance with the requirements of just war and ultimately ensures that strategy continues to function in the post-deterrence environment. This paper assesses whether a warfighting for deterrence approach is suitable for the cyber domain. In doing so, it challenges the notion that warfighting concepts are unsuitable for operations in cyberspace. To do this, the work constructs a conceptual framework that is then applied to cyber deterrence. It is found that all of the advantages of taking a warfighting stance apply to cyber operations. The paper concludes by constructing a warfighting model for cyber deterrence. This model includes passive and active defences and cross-domain offensive capabilities. The central message of the paper is that a theory of victory (strategy) must guide the development of cyber deterrence

Britain's emerging cyber-strategy

© RUSI JOURNAL AUGUST/SEPTEMBER 2016. In recent years, cyber-power has attracted a great deal of attention in government strategy and security reviews. This has been matched by regular increases in budget and the establishment of new organisations to co-ordinate UK activity in cyberspace. The result is the emergence of UK cyber-strategy. However, David J Lonsdale argues that at present UK cyber-strategy is not comprehensive, nor does it cohesively bring together the different elements of cyber-power to effectively serve UK policy objectives. Here, he identifies the components of the UK’s emerging cyber-strategy and assesses the UK’s approach against a comprehensive cyber-strategy framework. The latter includes seven elements: defence; cyber-espionage; information manipulation; widespread disruptive attacks; raids; joint operations; and deterrence

Ordering and controlling the dimensions of strategy

Colin Gray’s dimensions of strategy, built upon the earlier work of Clausewitz and Howard, has theoretical, practical, and pedagogic value for the Strategic Studies community. This paper further develops the theory, arguing that the dimensions can be controlled or managed to improve strategic performance. The dimensions are divided into two categories: “internal” and “external” to the process of strategy. The paper describes the dynamic process by which the internal dimensions, which can be controlled, are used to exert influence over the external dimensions that are beyond the control of the strategist. It is argued that six dimensions hold the key to strategic success: politics and the five dimensions concerned with warfighting. This conclusion validates the Clausewitzian paradigm with its emphasis on policy and battle

The 2018 Nuclear Posture Review: A return to nuclear warfighting?

© 2019 Taylor & Francis Group, LLC. The 2018 Nuclear Posture Review (NPR) represents a significant shift in U.S. nuclear weapons policy. Using Cold War vintage theory, this article assesses whether the NPR signals a return to nuclear warfighting. The NPR is assessed against five primary drivers for warfighting strategy: enhanced deterrence; to deal with deterrence failure; to maximize damage limitation; to provide a theory of victory; and adherence to just-war theory. The article concludes that although the NPR represents a step in the direction of warfighting, it does not fully embrace it. This is primarily because the NPR fails to endorse an unrestrained theory of victory

Infrared Properties of High Redshift and X-ray Selected AGN Samples

The NASA/ISO Key Project on active galactic nuclei (AGN) seeks to better understand the broad-band spectral energy distributions (SEDs) of these sources from radio to X-rays, with particular emphasis on infrared properties. The ISO sample includes a wide variety of AGN types and spans a large redshift range. Two subsamples are considered herein: 8 high-redshift (1 < z < 4.7) quasars; and 22 hard X-ray selected sources. The X-ray selected AGN show a wide range of IR continuum shapes, extending to cooler colors than the optical/radio sample of Elvis et al. (1994). Where a far-IR turnover is clearly observed, the slopes are < 2.5 in all but one case so that non-thermal emission remains a possibility. The highest redshift quasars show extremely strong, hot IR continua requiring ~ 100 solar masses of 500 - 1000 Kelvin dust with ~ 100 times weaker optical emission. Possible explanations for these unusual properties include: reflection of the optical light from material above/below a torus; strong obscuration of the optical continuum; or an intrinsic deficit of optical emission.Comment: 8 pages, 3 figures (2 color), to be published in the Springer Lecture Notes of Physics Series as part of the proceedings for "ISO Surveys of a Dusty Universe," a workshop held at Ringberg Castle, Germany, November 8 - 12, 1999.

Detection of Crab Giant Pulses Using the Mileura Widefield Array Low Frequency Demonstrator Field Prototype System

We report on the detection of giant pulses from the Crab Nebula pulsar at a frequency of 200 MHz using the field deployment system designed for the Mileura Widefield Array's Low Frequency Demonstrator (MWA-LFD). Our observations are among the first high-quality detections at such low frequencies. The measured pulse shapes are deconvolved for interstellar pulse broadening, yielding a pulse-broadening time of 670$\pm$100 $\mu$s, and the implied strength of scattering (scattering measure) is the lowest that is estimated towards the Crab nebula from observations made so far. The sensitivity of the system is largely dictated by the sky background, and our simple equipment is capable of detecting pulses that are brighter than $\sim$9 kJy in amplitude. The brightest giant pulse detected in our data has a peak amplitude of $\sim$50 kJy, and the implied brightness temperature is $10^{31.6}$ K. We discuss the giant pulse detection prospects with the full MWA-LFD system. With a sensitivity over two orders of magnitude larger than the prototype equipment, the full system will be capable of detecting such bright giant pulses out to a wide range of Galactic distances; from $\sim$8 to $\sim$30 kpc depending on the frequency. The MWA-LFD will thus be a highly promising instrument for the studies of giant pulses and other fast radio transients at low frequencies.Comment: 10 pages, 6 figures, Accepted for publication in the Astrophysical Journa

Galaxy Clustering in Far-Infrared SWIRE Fields

We present measurements of galaxy clustering detected in the six SWIRE fields in all MIPS channels at 24, 70, and 160 microns. The measurements include the low-order 2-point angular correlation functions, and high-order probes including probability distribution functions and Rényi information

Optical Spectroscopy of Supernova 1993J During Its First 2500 Days

We present 42 low-resolution spectra of Supernova (SN) 1993J, our complete collection from the Lick and Keck Observatories, from day 3 after explosion to day 2454, as well as one Keck high-dispersion spectrum from day 383. SN 1993J began as an apparent SN II, albeit an unusual one. After a few weeks, a dramatic transition took place, as prominent helium lines emerged in the spectrum. SN 1993J had metamorphosed from a SN II to a SN IIb. Nebular spectra of SN 1993J closely resemble those of SNe Ib and Ic, but with a persistent H_alpha line. At very late times, the H_alpha emission line dominated the spectrum, but with an unusual, box-like profile. This is interpreted as an indication of circumstellar interaction.Comment: 19 pages plus 13 figures, AASTeX V5.0. One external table in AASTeX V4.0, in landscape format. Accepted for publication in A
