OK, that's not necessarily a bad thing. At least you know that it's working: the
book is worth it because it is challenging you.

I'm a wee bit concerned about you saying that you need to make flash cards.
That's not necessarily a bad thing: it could be the way that you learn, and it
definitely cements the material as you consider *how* to make a flash card. But
brute memorization isn't the point. Make sure that you are understanding the
fundamental concepts as you go. (And, possibly, making flash cards might be the
way to do that ...)

Re: 01 May 2021 CBK for cissp exam

Mario,

 

Thank you.  You are correct.  After I thought about your answer I adjusted my thinking.  Instead of reading a sentence, paragraph, and chapter and going over every scenario that I thought they could ask a question about the content instead I asked what is the overall concept of that paragraph.  What is the main point/concept being made. 

 

I was also comparing protocols and devices used at the OSI layers from different books.  I decided to go with
"The Official (ISC)2 CISSP CBK Reference) 5th ed.  I like how this book includes the attack vectors common for each layer. 

 

If you have some questions on the OSI model layers that firewalls fit into:

 

Application Firewalls is layer 7 Application Layer

Application Firewalls could also be called Proxies "Forward and Reverse Proxies"

 

Stateful filtering firewall Layer 5

 

Packet filtering firewall is Layer 3

 

Layer 5 and Layer 7 are proxy because they can block. 

two types of Proxy Firewalls Circuit level (layer 5) and Application (Layer 7)

 

Is the above correct or do I need to go back and reread? 

 

Is there a difference between Circuit level proxy and Circuit layer firewall?

 

Thank you for any help / guidance
