Question

In class, we discussed a scenario involving 802.11, VPN, and ssh identifying three distinct 6. points of encryption. For each of these, describe what compromises, if any, would be possible by removing that encryption. The point of this question is to determine to what degree you can incrementally move to a better architecture by making stepwise changes to the existing structure.

Answer 1

If we remove the 802.11's encryption part then your wireless network will not be secure. Intruders can easily able to connect yo your wireless network and can plant malware easily into your network. Generally the IEEE 802.11 protocol is used by WPA and removing the encryption and password protection will make your network vulnerable.

VPN or the Virtual Private Network is used to connect one private network to another with the help public Network. VPN generally uses SHA encryption that will create a secure tunnel to connect to the corporate network. So, if we remove the encryption part from the VPN then attacker can easily connect to the corporate network and can collect and exploit the data from the corporate network.

SSH protocol uses the SHA encryption algorithm to encrypt the public key and store it in .sshd_pub file. So removing the encryption from SSH protocol will allow any user to remotely connect to the machine and make changes to the machine.

So, encryption plays a vital role in providing security to the infrastructure.So, we can also add more security by enabling multi-factor authentication where a code will generate in your mobile and it should be needed to connect to the network. This code will keep on changing after 10 seconds and a new code will generate.
