Question 1 of 30
In a financial institution, sensitive customer data is stored in a database that requires encryption to comply with regulatory standards such as GDPR and PCI DSS. The institution decides to implement AES (Advanced Encryption Standard) with a key size of 256 bits for encrypting this data. If the institution needs to encrypt a dataset containing 1,000,000 records, each record being 1 KB in size, what is the total amount of data (in bits) that will be encrypted, and how does the choice of AES-256 impact the security of the encrypted data compared to AES-128?
8,000,000,000 bits; AES-256 provides a higher level of security due to its longer key length, making it more resistant to brute-force attacks compared to AES-128.
1,000,000,000 bits; AES-256 is less secure than AES-128 due to its complexity.
8,000,000,000 bits; AES-128 is more secure than AES-256 because it is faster.
1,000,000,000 bits; AES-256 and AES-128 provide the same level of security.
