The security challenges for DRM are as follows:
Key hiding: It prevents tampering attacks that target the secret keys. In the key hiding process, secret keys are used for
authentication, encryption, and node-locking.
Device fingerprinting: It prevents fraud and provides secure authentication. Device fingerprinting includes the summary of hardware
and software characteristics in order to uniquely identify a device.
OTA provisioning: It provides end-to-end encryption or other secure ways for delivery of copyrighted software to mobile devices.
Answer B is incorrect. Access control is not a security challenge for DRM.

Surprised to see TCB mentioned, I always thought it was more niche!

Wait, isn't TCB just part of a larger system?

I disagree, I think IPSec plays a bigger role in security.

I thought it was CDSA, but TCB makes sense too.

I’m a bit confused. I thought IPSec was more about network security rather than the totality of protection mechanisms. Is that correct?

I practiced a question similar to this, and I think TCB is definitely the right choice. It covers hardware and software as part of security enforcement.

I'm not entirely sure, but I remember something about CDSA being related to security architecture. Could it be A?

I think the answer might be C, Trusted Computing Base. It seems to fit the description of all protection mechanisms working together.

Okay, I've got a strategy for this. I'll start by thinking about the different security controls mentioned and what they each do, then I'll choose the one that best fits the description in the question.

I'm a little confused by the wording of this question. I'll need to re-read it a few times to make sure I'm understanding it correctly before answering.

The key here is understanding what a "trusted computing base" is and how it relates to the security of a computer system. I'm confident I can get this right.

This is a good question. I'll need to consider the implications of an automatically generated system or environment.

Hmm, this seems like a tricky one. I'll need to think carefully about the differences between incidents and problems to decide if they can use the same categories.

This reminds me of a practice question we had on server overloads. I lean towards Denial of Service for this one.

The trusted computing base? More like the 'I don't trust anything' base, am I right? But hey, at least it's keeping us safe from the cyber-boogeyman.
