To answer this question, you need to understand secure coding practices and common vulnerabilities. Let's go through each option to understand why it is correct or incorrect:
Option A) Error handling - This option is incorrect because error handling is a practice used to manage and handle errors in a program, but it does not specifically address the issue of an attacker sending large amounts of data.
Option B) SQL Injection attack - This option is incorrect because SQL injection is a different type of vulnerability where an attacker can manipulate SQL queries to gain unauthorized access to a database. It is not directly related to the scenario described in the question.
Option C) Data and Input Validation - This option is incorrect because while data and input validation are important secure coding practices, they do not specifically address the issue of an attacker sending large amounts of data.
Option D) Buffer overflow attack - This option is correct because a buffer overflow attack occurs when an attacker sends more data than a program or application can handle, causing it to overwrite adjacent memory areas. This can lead to crashes, data corruption, and even the execution of malicious code.
The correct answer is D) Buffer overflow attack. This option is correct because it directly addresses the specific vulnerability described in the question.
