Buffer overflow attacks are prevented by input validation.

c Buffer overflow attacks can be prevented by implementing proper input validation & boundary checking in software, using secure coding practices, applying compiler-based protections like stack canaries & Address Space Layout Randomization [ASLR] & keeping software up to date with security patches.

The answer is: C. input validation.

The action that can help prevent buffer overflow attacks is: C. input validation Buffer overflow attacks occur when a program or application attempts to write data beyond the boundaries of a buffer, leading to overwriting adjacent memory areas. This can be exploited by an attacker to inject and execute malicious code. Input validation refers to the process of checking and validating user input to ensure it meets the expected criteria and does not exceed the allocated buffer size. By implementing proper input validation techniques, such as length checks, input sanitization, and boundary checks, developers can prevent buffer overflow vulnerabilities.

Several measures can be taken to prevent buffer overflows. These include address space layout randomization (ASLR), data execution prevention, and operating system runtime protections. ASLR is a technique that makes it harder for an attacker to predict where code will be executed in memory

C is correct (input sanitization)
