securing a network
to factor authentication should be used
passwords are often stored as hash
what is CAPTCHA
Completely Automated Public Turing test to tell Computers and Humans Apart
role of email confirmation
more secure
role of automatic software updates
fixes vulnerabilities in each individual piece of software , but not as quickly as pen testing
white-box testing
assumes knowledge of the internals of the system
stimulates attack from someone with detailed insider knowledge
black box testing
stimulates full on cyberattack
overwhelming the system with assumed system knowledge
brute-force attack
guessing every possible combination to get to the passwords
