Summary 📝

Penetration testing is a way to check how secure a computer system or network is by pretending to attack it, just like a real hacker might. It helps find weaknesses that could be used to break in. Companies use penetration testing to make sure their systems are protected before real attackers try to get in. There are different types of penetration testing, such as checking from the outside like a hacker (external testing) or from the inside as if someone has access already (internal testing). It also helps test if staff can spot a fake email or other trick. The goal is to find and fix problems before they cause harm. Penetration testers must always have permission and follow strict rules to make sure they stay within the law. 

Key learning Points 📌

• Penetration testing is a legal, planned attempt to test how secure a system is.

• It finds weak spots before real attackers can use them.

• It copies what a hacker might do to break in.
  
  

There are two main types:

• External testing – simulates an attack from outside the network.

• Internal testing – checks if damage can be done from within the network.

• Can include social engineering to test if people can spot tricks.
  
  

• Results are reported so the system can be improved.
  
  

• Testers must have permission before starting a test.
  
  

• Helps protect personal data and prevent cyber attacks.
