Identifying and preventing vulnerabilities

What you need to know

Passwords protect user accounts and systems by ensuring only authorised users can log in. Strong passwords are long, complex, and difficult to guess, making brute-force attacks much harder.

Key points

  • Definition:Password: a secret string of characters used to verify a user's identity and protect access to accounts and systems.
  • Strong passwords should be: long, contain a MIX of uppercase, lowercase, numbers, and symbols, and be HARD TO GUESS.
  • Help prevent: brute-force attacks, unauthorised access to accounts.
  • Passwords should be changed regularly and not reused across multiple accounts.
  • Exam Tip:If asked how to make passwords more secure, mention: LENGTH, COMPLEXITY (mix of character types), avoiding dictionary words, and not reusing passwords.
