Buffer Overflow is a type of cyber attack that can cause a great deal of damage to a computer system. It occurs when a program or process tries to write more data to a fixed-length memory buffer than the buffer is capable of holding. This results in the overwriting of adjacent memory, corrupting or overwriting important data, and crashing the system or causing it to behave erratically.
Buffer Overflow attacks can be executed in many different ways. One of the most common methods is to send a malicious code to a vulnerable program or process in order to cause it to overflow its buffer and execute the code. This code can then be used to gain access to the system or take control of the system.
Buffer Overflow attacks can be difficult to detect and prevent. It is important to use strong coding practices, such as avoiding the use of fixed-length buffers, checking the length of user input before accepting it, and using secure coding methods. It is also important to patch any known vulnerability in the system and to use a good security suite to detect and block any malicious code that is sent to the system.
Buffer Overflow attacks can cause a great deal of damage to a system, so it is important to take steps to prevent them. By taking the necessary precautions and using secure coding practices, organizations can reduce the risk of these types of attacks and protect their systems from malicious code.
