Role-based lateral movement detection with unsupervised learning
Brian A. Powell
Adversarial lateral movement via compromised accounts remains difficult to discover via traditional rule-based defenses because it generally lacks explicit indicators of compromise…
Malicious Overtones: hunting data theft in the frequency domain with one-class learning
Brian A. Powell
A method for detecting electronic data theft from computer networks is described, capable of recognizing patterns of remote exfiltration occurring over days to weeks. Normal traffi…
The epidemiology of lateral movement: exposures and countermeasures with network contagion models
Brian A. Powell
An approach is developed for analyzing computer networks to identify systems and accounts that are at particular risk of compromise by an adversary seeking to move laterally throug…
The Degeneracy Problem in Non-Canonical Inflation
Damien A. Easson, Brian A. Powell
While attempting to connect inflationary theories to observational physics, a potential difficulty is the degeneracy problem: a single set of observables maps to a range of differe…
Scalar runnings and a test of slow roll from CMB distortions
Brian A. Powell
A future measurement of cosmic microwave μ-distortions by an experiment with the specifications of PIXIE will provide an equivalent 3-sigma detection of the running of running of t…
Inflaton or Curvaton? Constraints on Bimodal Primordial Spectra from Mixed Perturbations
William H. Kinney, Azadeh Moradinezhad Dizgah, Antonio Riotto
We consider Cosmic Microwave Background constraints on inflation models for which the primordial power spectrum is a mixture of perturbations generated by inflaton fluctuations and…
