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?

You are an ethical hacker contracted to conduct a security audit for a company. During the audit, you discover that the company's wireless network is using WEP encryption. You understand the vulnerabilities associated with WEP and plan to recommend a more secure encryption method. Which of the following would you recommend as a suitable replacement to enhance the security of the company's wireless network?

You are the lead cybersecurity analyst at a multinational corporation that uses a hybrid encryption system to secure inter-departmental communications. The system uses RSA encryption for key exchange and AES for data encryption, taking advantage of the strengths of both asymmetric and symmetric encryption. Each RSA key pair has a size of 'n' bits, with larger keys providing more security at the cost of slower performance. The time complexity of generating an RSA key pair is O(n^2), and AES encryption has a time complexity of O(n). An attacker has developed a quantum algorithm with time complexity O((log n)^2) to crack RSA encryption. Given 'n=4000' and variable 'AES key size', which scenario is likely to provide the best balance of security and performance?

An experienced cyber attacker has created a fake LinkedIn profile, successfully impersonating a high-ranking official from a well-established company, to execute a social engineering attack.
