À pas mesurés
Ma montre valse
Sur l'air du temps
Autant de mots que de grains dans l'épi, un seul épi, un seul, pas davantage même s'il tombe des charrettes.
This first book on this fascinating, interdisciplinary topic meets the much-felt need for an up-to-date overview of the field.
Written with both beginners and professionals in mind, this ready reference begins with an introductory section explaining the basics of the various multi-photon and photochemical processes together with a description of the equipment needed. A team of leading international experts provides the latest research results on such materials as new photoinitiators, hybrid photopolymers, and metallic carbon nanotube composites. They also cover promising applications and prospective trends, including photonic crystals, microfluidic devices, biological scaffolds, metamaterials, waveguides, and functionalized hydrogels.
By bringing together the essentials for both industrial and academic researchers, this is an invaluable companion for materials scientists, polymer chemists, surface chemists, surface physicists, biophysicists, and medical scientists working with 3D micro- and nanostructures.
Learn the risks associated with Network Time Protocol (NTP) security and how to minimize those risks while deploying and managing the protocol. You will be able to reduce the disruption of communication between servers on the network and the risk that the entire network will be taken offline.
NTP Security: A Quick-Start Guide provides an understanding of how NTP is critical to modern networks and how it can be exploited. You will understand how an attacker can wreak havoc on an insecure network and guidance is provided to help you manage your system and make it more secure. What You Will Learn:
Understand the vulnerabilities, flaws, and risks associated with the Network Time protocol (NTP)Analyze NTP traffic and configure NTP on servers and workstations in the network in a more secure manner Use practical solutions to secure NTP and build a robust infrastructure, such as bringing more capability inside the network and creating a smaller attack surface
Determine the alternatives to NTP, including how to synchronize network clocks in other ways
Who This Book Is For:
System administrators, network engineers, and security analysts
