What is the gaps and weaknesses of basic WAP transmission model?

Azuki

The basic WAP transmission involving a WAP client, a WAP gateway and a Web Server results in a security gap. By appraising
the basic WAP transmission model identify the gaps and weaknesses listed below:-
1. Within the gateway, data are not encrypted during the translation process
2. WTLS encryption is weaker than TLS and hence is easily compromised.
3. There is no end-to-end protection for data
4. The WAP gateway can be compromised resulting in data leakage
5. The WAP device and Web Server can be compromised.

(a) All of the above
(b) 1, 3 & 4
(c) 1, 2 & 5
(d) 3, 4 & 5
(e) 1, 2, 3 & 5

I would think it's (b). But I feel really unsure. Can someone please help to verify?

Thanks!

I think you're right.

I would not say that WTLS can be easily compromised, therefore the correct answer should not contain option 2. So we have (b) and (d) left. Option 3 and 4 should be correct then. Well, there is no end-to-end protection for sure WAP gateway can be compromised. Option 5 should be eliminated, because you can not make a general statement like that.

Can anyone confirm or oppose please?
