A standard network communication protocol

Floods a target server with a huge number of fake requests

Tricks an unsuspecting user with a convincing fake email

Tries many possible passwords until one works

It floods a system so it cannot serve genuine users

To deliberately attack a system, with permission, to find weaknesses

To train all of the users about the dangers of phishing

They block every bit of incoming network traffic

They make the central CPU run noticeably faster

They can be tricked or pressured into making mistakes

They tend to use far too many different passwords

They are completely unable to use any computers properly at all

They never bother to read any of their emails
