Intro to Cyber Security & Ethical Hacking
Cyber Security is the
practice of defending computers,
servers, mobile devices, electronic
systems, networks, and data from
malicious attacks. It's also known as
information technology security or
electronic information security. The
term applies in a variety of contexts,
from business to mobile computing,
and can be divided into a few
common categories.
Ethical Hacker, also
referred to as a white hat hacker, is an
information security (infosec) expert
who penetrates a computer system,
network, application or other
computing resource on behalf of its
owners -- and with their authorization.
Organizations call on ethical hackers to
uncover potential security
vulnerabilities that malicious hackers
could exploit.
