Network Performance Security: Testing and Analyzing Using Open Source and Low-Cost Tools gives mid-level IT engineers the practical tips and tricks they need to use the best open source or low cost tools available to harden their IT infrastructure. The book details how to use the tools and how to interpret them. Network Performance Security: Testing and Analyzing Using Open Source and Low-Cost Tools begins with an overview of best practices for testing security and performance across devices and the network. It then shows how to document assets—such as servers, switches, hypervisor hosts, routers, and firewalls—using publicly available tools for network inventory. The book explores security zoning the network, with an emphasis on isolated entry points for various classes of access. It shows how to use open source tools to test network configurations for malware attacks, DDoS, botnet, rootkit and worm attacks, and concludes with tactics on how to prepare and execute a mediation schedule of the who, what, where, when, and how, when an attack hits. Network security is a requirement for any modern IT infrastructure. Using Network Performance Security: Testing and Analyzing Using Open Source and Low-Cost Tools makes the network stronger by using a layered approach of practical advice and good testing practices.

Fundamentals of Seismic Wave Propagation presents a comprehensive introduction to the propagation of high-frequency body-waves in elastodynamics. The theory of seismic wave propagation in acoustic, elastic and anisotropic media is developed to allow seismic waves to be modelled in complex, realistic three-dimensional Earth models. This book provides a consistent and thorough development of modelling methods widely used in elastic wave propagation ranging from the whole Earth, through regional and crustal seismology, exploration seismics to borehole seismics, sonics and ultrasonics. Particular emphasis is placed on developing a consistent notation and approach throughout, which highlights similarities and allows more complicated methods and extensions to be developed without difficulty. This book is intended as a text for graduate courses in theoretical seismology, and as a reference for all academic and industrial seismologists using numerical modelling methods. Exercises and suggestions for further reading are included in each chapter.

Big Finish have been producing Doctor Who audios since 1999, starring Tom Baker, Peter Davison, Colin Baker, Sylvester McCoy, Paul McGann, David Tennant and John Hurt.

It's London, 1828, and the father-and-son team of Marc and Isambard Kingdom Brunel are masterminding a dangerous project -the digging of the Thames Tunnel. There's just one problem - the Brunels' tunnel is haunted and every night, a spectral blue lady walks the excavation!

July 1944: The TARDIS materialises in a small village near Rouen,where celebrations are in full swing. A joyful France is in the midst of liberation as the local population welcome a battalion of Allied soldiers –along with a colourfully dressed Doctor and his two rather excited friends. But there are screams amidst the celebrations as an angry crowd dish out their brand of justice to one of their own that they have branded a traitor. While Constance and Flip find themselves on opposite sides of a war beyond a war, the Doctor has other concerns.The local community is used to the fires of battle, but a new type of blaze is burning –leaping from aircraft to aircraft, man to man –and this fire seems to be just as eager for revenge as the village mob.Cast: Colin Baker (The Doctor), Lisa Greenwood(Flip Jackson), Miranda Raison (Constance Clarke), Philip DeLancy (Lucien/Max), Christopher Black (Walter/Jurgen), James Boswell(Harris/Klaus), Katarina Olsson (Clementine).
