When securing against broken authentication, which control is NOT relevant for protection?

• A. MFA (Multifactor Authentication)
• B. Password check
• C. Set limits
• D. Enable ASLR (Address Space Layout Randomization)

Answer: (D)

In the context of securing against broken authentication, enabling Address Space Layout Randomization (ASLR) is not a relevant control for this specific problem. ASLR is a security technique used to prevent exploitation of memory corruption vulnerabilities by randomizing the memory addresses used by executable files and their data. While ASLR is critical for mitigating certain types of attacks, particularly those that exploit memory corruption, it does not directly address vulnerabilities related to authentication mechanisms. On the other hand, measures such as multi-factor authentication (MFA) strengthen user authentication by requiring additional verification methods beyond just a password. Password checks ensure that user passwords meet particular strength criteria, while setting limits on authentication attempts helps mitigate brute-force attacks by preventing attackers from continually trying different password combinations. Therefore, while all other options directly contribute to improving the security of authentication systems, ASLR does not specifically protect against the issues surrounding broken authentication.
