Web security and OWASP

Understand why web apps need protection and how OWASP guides developers.

📖 Key ideas

  1. Web apps are reachable by anyone on the internet, so security must be designed in.
  2. OWASP is a non-profit that publishes free application security guidance.
  3. The OWASP Top 10 lists the most critical web application risks.
  4. Secure development means considering security in every phase.
  5. Security testing is only done on systems you own or are authorised to test.
💡 Real-life example: The OWASP Top 10 is a builder's checklist of the weakest spots in a house, so they get reinforced first.
