What is black box penetration testing?
When they are given little or no information about the network before the test.
Designed to prevent an outside attack.
What is the difference between black box and white box penetration testing?
Black box - little to no information before the test.

What is worms?
Worms spread like viruses but do not require human intervention.
They attach themselves to network tools to spread automatically around a network quickly
Name 6 ways to detect / prevent cyber security threats.
- Biometric measures (Fingerprints)
2.Automatic software updates
- CAPTCHA (Using images to see if its a bot or human)
- Password systems
- Using a email for confirmation
- Anti virus software (Scans computer to find malware)
What is blagging
