GAQM CPEH-001 Exam - Topic 3 Question 53 Discussion

In the context of using PKI, when Sven wishes to send a secret message to Bob, he looks up Bob's public key in a directory, uses it to encrypt the message before sending it off. Bob then uses his private key to decrypt the message and reads it. No one listening on can decrypt the message. Anyone can send an encrypted message to Bob but only Bob can read it. Thus, although many people may know Bob's public key and use it to verify Bob's signature, they cannot discover Bob's private key and use it to forge digital signatures. What does this principle refer to?
D) Asymmetry
A) Irreversibility
B) Non-repudiation
C) Symmetry

Suggested Answer: D

PKI uses asymmetric key pair encryption. One key of the pair is the only way to decrypt data encrypted with the other.

Yup, only Bob can decrypt with his private key!

Just to clarify, anyone can encrypt with the public key, right?

Wait, are we sure it's not non-repudiation?

I keep mixing up these terms! I thought irreversibility was important, but now I'm leaning towards asymmetry since it deals with the public and private keys.

I practiced a similar question, and I think the key aspect here is that only Bob can decrypt the message, which points to asymmetry.

I'm not entirely sure, but I feel like non-repudiation might be the right answer since it involves verifying signatures.

I remember studying PKI, and I think this principle is related to how public and private keys work together. Maybe it's asymmetry?

I'm feeling a bit lost on this one. The terminology around "Privileged Session Management" and "PSM Gateway" is not something I'm familiar with. I'll have to do some quick research on these concepts before I can confidently select an answer. Hopefully I can figure it out in time for the exam.

Alright, I got this. The key here is that we need to remove the file from the staging area, not delete it. So the git reset HEAD devcoreg13642911.jpg command is the way to go. Confident I can get this one right.

I seem to remember something about Avaya Secure Access Link being the recommended tool, but I'm not completely sure.

I'm leaning towards C. Incident Management, since that's all about responding to and resolving incidents quickly. But I'll double-check the definitions to be sure.
