What you'll learn

Each question helps you build key knowledge and skills.

  • 1Brute force attacks systematically try many password combinations, while denial of service attacks flood a server with traffic to make it unavailable to legitimate users.
  • 2A distributed denial of service attack uses many devices, often a botnet, at once, making it much harder to block than an attack from a single source.
  • 3SQL injection attacks insert malicious code into database queries through vulnerable input fields, and can be prevented through input validation.
  • 4Symmetric encryption uses one shared key while asymmetric encryption uses a public and private key pair, each suited to different situations.
  • 5Penetration testing involves authorised experts simulating attacks to find and fix vulnerabilities before criminals can exploit them, and organisations often support this with clear acceptable use policies.
