ISC2 ISSEP Exam - Topic 5 Question 46 Discussion

Actual exam question for ISC2's ISSEP exam
Question #: 46
Topic #: 5
[All ISSEP Questions]

You have been tasked with finding an encryption methodology that will encrypt most types of email

attachments. The requirements are that your solution must use the RSA algorithm. Which of the

following is your best choice?

Show Suggested Answer Hide Answer
Suggested Answer: B

Secure/MIME, a version of the MIME protocol that supports encryption of messages and is based on

RSA's public-key encryption. Multipurpose

Internet Mail Extensions (MIME) is an Internet standard for email attachments.

Answer options D and C are incorrect. Blowfish and DES are both symmetric key algorithms and they

are not used with email attachments.

Answer option A is incorrect. PGP (Pretty Good Privacy) is used to secure email, but not email

attachments, and it is not based on RSA.

Really? I thought S/MIME was the standard for email security.

Wait, why isn't anyone mentioning the security of PGP vs S/MIME?

DES and Blowfish aren't even RSA-based, right?

I think S/MIME is better for email attachments.

PGP is the way to go for RSA encryption!

I practiced a similar question, and I think PGP was the answer there as well. But I'm still a bit unsure.

DES and Blowfish don't seem to fit since they don't use RSA. I feel like I should eliminate those.

I'm not entirely sure, but I think S/MIME also supports RSA. It could be a good option too.

I remember studying that PGP uses RSA for encryption, so I think it might be the right choice here.

I'm a bit unsure about this one. Is an open port 25 always a security risk, or could there be legitimate reasons for it? I'll need to research this a bit more to understand the potential threats.

I'm a little confused by the wording of the question. Are we supposed to choose two options, or are there multiple correct answers? I'll need to read through it again carefully.

I'm a little confused by the options here. The question mentions XML or JSON encoding, but none of the choices seem to directly address that requirement. I'm leaning towards NX-API and HTTPS, but I'm not 100% sure that's the best solution. I might need to do some additional research to make sure I'm choosing the right components.
