ISC2 ISSAP Exam - Topic 3 Question 75 Discussion

Actual exam question for ISC2's ISSAP exam
Question #: 75
Topic #: 3
[All ISSAP Questions]

Which of the following security protocols provides confidentiality, integrity, and authentication of network traffic with end-to-end and intermediate-hop security?

Show Suggested Answer Hide Answer
Suggested Answer: A

password to each application. In SSO, a user can access all computer applications and systems where he has access permission without

entering multiple passwords. This reduces human error and systems failure and is therefore highly desirable. There are many commercial SSO

solutions available in the market. Some of them are as follows:

Central Authentication Service (CAS)

The Dutch NREN

CoSign

Enterprise Single Sign-On (E-SSO)

Web Single Sign-On (Web SSO)

Security Assertion Markup Language (SAML)

Direct SSO

Shibboleth

Answer option B is incorrect. A one-time password (OTP) is a password only valid for a single login session or transaction. OTP avoids a

number of shortcomings that are associated with traditional passwords. The most important shortcoming that is addressed by OTP is that OTP

is not vulnerable to replay attacks. If a potential intruder manages to record an OTP that was already used to log into a service or to conduct

a transaction, he will not be able to abuse it since it will be no longer valid.

Answer option D is incorrect. Kerberos is a secure protocol that supports ticketing authentication. A ticket is granted in response to a client

computer authentication request by the Kerberos authentication server, if the request contains valid user credentials and a valid Service

Principal Name (SPN). The ticket is then used by the client computer to access network resources. To enable Kerberos authentication, the

client and server computers must have a trusted connection to the domain Key Distribution Center (KDC). The task of KDC is to distribute

shared secret keys to enable encryption.

Answer option C is incorrect. In the dynamic password authentication scheme, passwords are changed after a specified time or time interval.

I’m leaning towards IPSec too, but I vaguely remember something about SKIP being used for key management. Not sure if it fits this question though.

SWIPE sounds familiar, but I can't recall its specific use case. I feel like it might not cover all the requirements mentioned in the question.

I remember practicing a question about security protocols, and I think SET was related to secure transactions, but it doesn’t provide the same level of network security as IPSec.

I think IPSec is the right answer because it’s often used for securing IP communications, but I'm not completely sure about the other options.

I'm a bit unsure about this one. Does the question mean that reducing maintenance costs by delivering a quality product will impact ROI? Or is it saying that delivering a quality product will reduce maintenance costs, which will then impact ROI? I'll have to think this through carefully.

IPSec all the way! It's the gold standard for network security. The other choices sound like something you'd find in a spy novel, not a real-world networking exam.
