Question #: 162
Topic #: 1
[All 312-50v12 Questions]

Consider a hypothetical situation where an attacker, known for his proficiency in SQL Injection attacks, is targeting your web server. This adversary meticulously crafts 'q' malicious SQL queries, each inducing a delay of 'd' seconds in the server response. This delay in response is an indicator of a potential attack. If the total delay, represented by the product 'q*d', crosses a defined threshold 'T', an alert is activated in your security system. Furthermore, it is observed that the attacker prefers prime numbers for 'q', and 'd' follows a pattern in the Fibonacci sequence. Now, consider 'd=13' seconds (a Fibonacci number) and various values of 'q' (a prime number) and 'T'. Which among the following scenarios will most likely trigger an alert?

  • A. q=17, T=220: Even though the attacker increases 'q', the total delay ('q*d' = 221 seconds) just surpasses the threshold, possibly activating an alert.
  • B. q=13, T=180: In this case, the total delay caused by the attacker ('q*d' = 169 seconds) breaches the threshold, likely leading to the triggering of a security alert.
  • C. q=11, T=150: Here, the total delay induced by the attacker ('q*d' = 143 seconds) does not surpass the threshold, so the security system remains dormant.
  • D. q=19, T=260: Despite the attacker's increased effort, the total delay ('q*d' = 247 seconds) does not exceed the threshold, thus no alert is triggered.
