ISC2 ISSAP Exam - Topic 5 Question 81 Discussion

Actual exam question for ISC2's ISSAP exam

Question #: 81
Topic #: 5

You work as a Chief Security Officer for Tech Perfect Inc. The company has a TCP/IP based network. You want to use a firewall that can track the state of active connections of the network and then determine which network packets are allowed to enter through the firewall. Which of the following firewalls has this feature?

AStateful packet inspection firewall

BProxy-based firewall

CDynamic packet-filtering firewall

DApplication gateway firewall

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a transaction, he will not be able to abuse it since it will be no longer valid.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

C sounds like it could work too, but A is the best choice.

I feel like proxy-based firewalls are more about filtering traffic at the application layer, so I would lean towards A as well.

I practiced a similar question where the focus was on connection states, and I think it pointed towards stateful firewalls too.

The key is identifying the firewall that can monitor the state of network connections. Based on that, I think the stateful packet inspection firewall is the right answer.

I'm voting for the stateful packet inspection firewall. It's the security equivalent of a parent keeping an eye on their kids' internet browsing history. Gotta love that level of parental control.

A stateful packet inspection firewall is definitely the answer here. It can track the state of active connections and make decisions based on that information. This is crucial for a robust network security strategy.
