1. Right Answer: C
Explanation: A script kiddie or skid is an unskilled individual who uses scripts or programs developed by others to attack computer systems and networks and deface websites.
2. Right Answer: B
Explanation: A brute-force attack consists of an attacker submitting many passwords or passphrases with the hope of eventually guessing it correctly. The attacker systematically checks all possible passwords and passphrases until the correct one is foun Alternatively, the attacker can attempt to guess the key, which is typically created from the password using a key derivation function.
3. Right Answer: C
Explanation: Contextual output encoding/escaping could be used as the primary defence mechanism to stop Cross-site Scripting (XSS) attacks.
4. Right Answer: C
Explanation: In computer science, a zombie is a computer connected to the internet that has been compromised by a hacker, computer virus or Trojan horse and can be used to perform malicious tasks of one sort or another under remote direction. Botnets of zombie computers are often used to spread email spams and launch Denial-of-Service attacks. Most owners of zombie computers are unaware that their system is being used in this way, these computers are metaphorically compared to zombies. A coordinated DDoS attack by multiple botnet machines also resembles a zombie horde attack.
5. Right Answer: A
Explanation: Cross-Site Scripting (XSS) allows an attacker to inject client side scripts into web pages viewed by other users. A cross-site scripting vulnerability may be used by attackers to bypass access controls such as the same-origin policy.
