A security architect is reviewing a legacy system that still uses DES. The system processes data that must remain confidential for 10 years. The architect knows that DES has a 56-bit key and is vulnerable to brute-force attacks. They are considering upgrading to 3DES or AES, but the system's hardware only supports DES and 3DES. Which option provides the strongest security while staying within the hardware constraint?
