Crash Course in Technology Planning

This easy-to-use primer will empower anyone—even those with no IT background—to face the challenge of adding one or more technologies to library services or maintaining existing technologies. Most of the public libraries in the United States are operating on tight budgets without allocation for IT personnel; in school libraries, the librarian often takes on the lion's share of IT responsibility. This book is an invaluable guide for library staff members who are put in the position of maintaining their own networks and computers with very little training or support. Authored by an assistant library director with years of firsthand experience working as a solo IT manager within public libraries, this guide provides practical information about overcoming the unique challenges of managing IT in a smaller organization, juggling multiple job roles, being limited by a restrictive budget, and working directly with the public. Crash Course in Technology Planning addresses a wide variety of IT topics in the library sphere, providing information in a logical manner and order. It begins with an explanation of triaging existing IT issues, then moves into diagnosing and repairing both individual PCs as well as the library Local Area Network (LAN). The following chapters cover other important topics, such as the best way to inventory computers and equipment, how to budget for and procure new equipment, and recommended ways for an IT layperson to set and achieve goals.
Ethernet Networking for the Small Office and Professional Home Office
In a local area network (LAN) or intranet, there are many pieces of hardare trying to gain access to the network transmission media at the same time (i.e., phone lines, coax, wireless, etc.). However, a network cable or wireless transmission frequency can physically only allow one node to use it at a given time. Therefore, there must be some way to regulate which node has control of the medium (a media access control, or MAC, protocol). Ethernet is a MAC protocol; it is one way to regulate physical access to network tranmission media. Ethernet networking is used primarily by networks that are contained within a single physical location. If you need to design, install, and manage a network in such an envronment, i.e., home or small business office, then Ethernet Networking for the Small Office and Professional Home Office will give you an in-depth understanding of the technology involved in an Ethernet network. One of the major goals of this book is to demystify the jargon of networks so that the reader gains a working familiarity with common networking terminology and acronyms. In addition, this books explains not only how to choose and configure network hardware but also provides practical information about the types of network devices and software needed to make it all work. Tips and direction on how to manage an Ethernet network are also provided. This book therefore goes beyond the hardware aspects of Ethernet to look at the entire network from bottom to top, along with enough technical detail to enable the reader to make intelligent choices about what types of transmission media are used and the way in which the various parts of the network are interconnected. - Explains how the Ethernet works, with emphasis on current technologies and emerging trends in gigabit and fast Ethernet, WiFi, routers, and security issues - Teaches how to design and select complementary components of Ethernet networks with a focus on home and small business applications - Discuses the various types of cables, software, and hardware involved in constructing, connecting, operating and monitoring Ethernet networks
Network Performance and Security
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. - Offers coherent, consistent guidance for those tasked with securing the network within an organization and ensuring that it is appropriately tested - Focuses on practical, real world implementation and testing - Employs a vetted "security testing by example" style to demonstrate best practices and minimize false positive testing - Gives practical advice for securing BYOD devices on the network, how to test and defend against internal threats, and how to continuously validate a firewall device, software, and configuration - Provides analysis in addition to step by step methodologies
