These terms define different groups of hackers based on their behavior. Black hats fit the widely-held stereotype that hackers are criminals performing illegal activities for personal gain and attacking others. Media portrayals of black-hat hackers may be accompanied by silly stock photos like the below one, which is intended as a parody. White Hats White-hat hackers are the opposite of the black-hat hackers.
Security vulnerabilities in Ethernet switches are multiple: LAN Switch Security explains all the vulnerabilities in a network infrastructure related to Ethernet switches.
Further, this book shows you how to configure a switch to prevent or to mitigate attacks based on those vulnerabilities. This book also includes a section on how to use an Ethernet switch to increase the security of a network and prevent future attacks.
Divided into four parts, LAN Switch Security provides you with steps you can take to ensure the integrity of both voice and data traffic traveling over Layer 2 devices.
Part I covers vulnerabilities in Layer 2 protocols and how to configure switches to prevent attacks against those vulnerabilities. Part II addresses denial-of-service DoS attacks on an Ethernet switch and shows how those attacks can be mitigated.
For all parts, most of the content is vendor independent and is useful for all network architects deploying Ethernet switches.
After reading this book, you will have an in-depth understanding of LAN security and be prepared to plug the security holes that exist in a great number of campus networks.

Hackers like to explore and learn how computer systems work. They try to take advantage of vulnerabilities or weakness of a software and hardware.
Hacking is the process of getting unauthorized access to a system, network or resources. A security hacker is someone who seeks to breach defenses and exploit weaknesses in a computer system or network. Hackers may be motivated by a multitude of reasons, such as profit, protest, information gathering,  challenge, recreation,  or to evaluate system weaknesses to assist in formulating defenses against potential hackers.
Knowing about these common hacking techniques for yourself. These types of hackers can target email, instant messaging services, phone calls, web browsing, and other methods of communication.
