Answer 1

Answering the first four :-

Question 1:

a. True, WLAN usually are connected to wired or fiber cables. But physical access would be required in this case, just as it is in the case of wired lan. So, not different from set of attacks from wired.

b. True, modern wireless tech in use enables hackers to easily monitor data and in the worst case, they can harm the integrity of data (This is the correct option)

c. False, WLAN is easy to set up and manage.

d. False, b. is correct.

Question 2:

a. False. Wardriving is the act of searching for a wifi network while driving a vehicle. It is not an integrity attack as it does not change the contents.

b. False. Denial of Service means to hamper the availability of network to an authorised user. It does not involve change in contents, so not an integrity attack.

c. True, Injecting frames implies modifying data. So, it is an integrity attack. (Answer).

d. False, Frequency jamming hampers availablity, so not an integrity attack.

Question 3:

a. True, the length is negotiable and after both parties agree , can be fixed during the pairing stage.

b. True, in Mode 1 of bluetooth, there's no authentication. Mode2 limits the authentication to application software. Mode 3 is the built-in security offered by bluetooth. It requires a PIN.

c. True, only individual links are encrypted and authenticated. Data is decypted during intermediate stages.

d. Hence True. (answer)

Question 4:

a. True, these are shared and are common to all users. Hence, a compromised device may compromise all devices.

b. True, If the attacker knows IV of every packet, he can exploit it because the shortcomings of RC4 and a short and static IV gurantees that the streams will repeat.

c. True, The IV is just 24 bit which is small. This ensures that they streams will repeat frequently.

d. True, Refer a. , b. c. (answer)
