During a vulnerability scan, a legacy software package was found that uses an outdated encryption scheme that can be brute forced. Which solution addresses the cryptographic threat?
Use a better cryptographic library and disable outdated protocols
Append an intrusion detection application to log suspicious traffic
Run frequent vulnerability assessments to track possible intrusions
Set up multi-factor authentication for the software
Using a robust cryptographic library addresses the main vulnerability by replacing algorithms that can be brute forced with stronger encryption. Monitoring for suspicious traffic does not protect the data exchanges themselves. Enforcing multi-factor authentication affects access control but does not fix the underlying encryption. Frequent assessments uncover risks but do not remove older algorithms from use.
