Strcpy(), strcat(), strncpy(), sprint(), gets() are all included in

technology security

  1. Safe APIs

  2. Banned APIs

  3. String APIs

  4. CAPIs

Show answer
Correct Option: B

AI Explanation

To answer this question, you need to understand the purpose and characteristics of these functions.

Option A) Safe APIs - This option is incorrect because some of the functions mentioned, such as gets(), are considered unsafe and can lead to buffer overflow vulnerabilities.

Option B) Banned APIs - This option is correct because some of the functions mentioned, such as gets(), are considered unsafe and have been banned in modern programming practices due to security concerns.

Option C) String APIs - This option is incorrect because while some of the functions mentioned, such as strcpy(), strcat(), and strncpy(), are related to manipulating strings, not all of them fall into this category.

Option D) CAPIs - This option is incorrect because the term "CAPIs" is not commonly used to refer to these functions.

The correct answer is B) Banned APIs. This option is correct because some of the functions mentioned, such as gets(), have been banned in modern programming practices due to security vulnerabilities.

NOP sled technique is a popular

technology security

  1. Reverse Engineering Technique

  2. Buffer Overflow Attack Technique

  3. Log Analysing Technique

  4. Data Analysis Technique

Show answer
Correct Option: B

AI Explanation

To answer this question, you need to understand the NOP sled technique and its purpose.

The NOP sled technique is a popular technique used in buffer overflow attacks.

A buffer overflow attack occurs when a program or system tries to store more data in a buffer than it was designed to hold. This can lead to the overwriting of adjacent memory locations, allowing an attacker to execute arbitrary code or take control of the system.

In a buffer overflow attack, the attacker injects malicious code into a buffer, and then overwrites the return address of a function with the address of the injected code. However, it can be challenging to precisely locate the injected code's address, especially if the buffer's size is not known.

This is where the NOP sled technique comes into play. NOP stands for "no operation," which is a type of instruction that does nothing when executed. The NOP sled is a long sequence of NOP instructions placed before the injected code. When the buffer overflow occurs, the execution flow will slide down the NOP sled until it reaches the injected code. This technique increases the chances of hitting the injected code's address, even if the exact location is not known.

Therefore, the correct answer is B) Buffer Overflow Attack Technique, as the NOP sled technique is commonly used in buffer overflow attacks.
