We study the holographic currents associated to ChernSimons theories. We start with an example in three dimensions and find the holographic representations of vector and chiral currents reproducing the correct expression for the chiral anomaly. In five dimensions, ChernSimons theory for AdS group describes first order gravity and we show that there exists a gauge fixing leading to a finite FeffermanGraham expansion. We derive the corresponding holographic currents, namely, the stress tensor and spin current which couple to the metric and torsional degrees of freedom at the boundary, respectively. We obtain the correct Ward identities for these currents by looking at the bulk constraint equations. 1

In the context of recently proposed holographic dualities between higher spin theories in AdS3 and (1 + 1)dimensional CFTs with W symmetry algebras, we revisit the definition of higher spin black hole thermodynamics and the dictionary between bulk fields and dual CFT operators. We build a canonical formalism based on three ingredients: a gaugeinvariant definition of conserved charges and chemical potentials in the presence of higher spin black holes, a canonical definition of entropy in the bulk, and a bulktoboundary dictionary aligned with the asymptotic symmetry algebra. We show that our canonical formalism shares the same formal structure as the socalled holomorphic formalism, but differs in the definition of charges and chemical potentials and in the bulktoboundary dictionary. Most importantly, we show that it admits a consistent CFT interpretation. We discuss the spin2 and spin3 cases in detail and generalize our construction to theories based on the hs[λ] algebra, and on the sl(N,R) algebra for any choice of sl(2,R) embedding.

Hostbased Intrusion Detection Systems can be used to determine if a system has been compromised and can warn administrators if that happens. We recognize four different methods of hostbased intrusion detection: • Filesystem monitoring. • Logfile analysis. • Connection analysis. • Kernelbased intrusion detection. Implementations of intrusion detection systems generally use one of these four methods to detect intrusions. We have studied multiple implementations, determined their features, ways of evading their restrictions and ways to prevent evasion. We have also given insight into the reasons why certain systems should or should not be used and to what extent, based on their effectiveness and ease of

Abstract: In a class of 2D CFTs with higher spin symmetry, we compute thermal twopoint functions of certain scalar primary operators in the presence of nonzero chemical potential for higher spin charge. These are shown to agree with the same quantity calculated holographically using scalar fields propagating in a charged black hole background of 3D higher spin gravity. This match serves as further evidence for the duality between WN minimal models at large central charge and 3D higher spin gravity. It also supports a recent prescription for computing boundary correlators of ‘multitrace ’ scalar primary operators in higher spin theories. ar X iv
