Discussion
Consider the following statements about key management.
1. Rotating a key limits the exposure of any single compromised key.
2. Keys and the data they protect should be under separate controls.
3. A key stored beside the data it encrypts provides good protection.
Answer: C
The first two are correct and are the core of key hygiene. The third defeats the purpose, since anyone who obtains the storage obtains both the ciphertext and the means to read it. Separating the two is the whole reason a key management service exists at all.
