CompTIA Server+ Certification Guide

By: Ron Price

Overview of this book

CompTIA Server+ Certification is one of the top 5 IT certifications that is vendor neutral.System administrators opt for CompTIA server+ Certification to gain advanced knowledge of concepts including troubleshooting and networking. This book will initially start with the configuration of a basic network server and the configuration for each of its myriad roles. The next set of chapters will provide an overview of the responsibilities and tasks performed by a system administrator to manage and maintain a network server. Moving ahead, you will learn the basic security technologies, methods, and procedures that can be applied to a server and its network. Next, you will cover the troubleshooting procedures and methods in general, and specifically for hardware, software, networks, storage devices, and security applications. Toward the end of this book, we will cover a number of troubleshooting and security mitigation concepts for running admin servers with ease. This guide will be augmented by test questions and mock papers that will help you obtain the necessary certification. By the end of this book, you will be in a position to clear Server+ Certification with ease.

Port security

Many switches and routers have all of their interfaces enabled by default, right out of the box. As we've discussed, hardening—that is, closing unused ports—helps to secure a network by closing possible entry points. There are several approaches, standards, and methods used to secure internetworking devices, especially routers and switches, most of which are port-based network access control (PNAC) methods.

Port-based security

In general terms, port-based security secures the interfaces (ports) of a switch by limiting the number or specific devices that may forward packets or frames to one or more of its ports. Port security has two approaches:

  • Dynamic locking: This sets the maximum number...
