If a disaster occurs at 2 PM and the last backup was completed at 1 PM, what is the maximum acceptable data loss in terms of time, and how should the company structure its DR plan to meet these objectives?

Accepted Answer

The maximum acceptable data loss is 1 hour, and the company should implement continuous data protection (CDP) to minimize data loss.

Question 22

A financial institution is implementing a new data encryption strategy to protect sensitive customer information. They decide to use symmetric encryption for data at rest and asymmetric encryption for data in transit. If the institution encrypts a file containing customer data using a symmetric key of length 256 bits, what is the theoretical maximum number of possible keys that can be generated for this encryption method? Additionally, if the institution uses RSA for encrypting data in transit with a key size of 2048 bits, how does the key size impact the security level compared to the symmetric encryption method?

Accepted Answer

The maximum number of possible keys for symmetric encryption is $2^{256}$, and RSA with 2048 bits provides a significantly higher security level due to the complexity of factoring large primes.
