 Sample answer: “My role as an Information Security Analyst is to protect my organisation's Information Systems and data. I would address Cybersecurity differently for cloud and on-premises computing in these ways: 

a) Risk assessment: I would identify and mitigate the risks associated with the Cloud Service Provider (CSP) or the physical and environmental security of the IT resources and evaluate their security features and capabilities. 

b) Security policy: I would develop and implement a security policy that aligns with the CSPs' or my organisation’s agreements and obligations and communicate and educate the users and stakeholders on the security best practices and guidelines. 

c) Security monitoring: I would use the security tools and reports provided by the CSP or my organisation to track and analyse the security events and activities and collaborate or coordinate with the relevant parties to resolve and report any security incidents or issues.”

17) What is the difference between symmetric and asymmetric encryption? 

Symmetric and asymmetric encryption are two types of encryption techniques used to protect data confidentiality. The difference between them is as follows: 

a) Key: Symmetric encryption uses the same key to encrypt data, while asymmetric encryption uses two keys for the same purpose. The key used in symmetric encryption is called a secret key, and the keys used in asymmetric encryption are called a public key and a private key. The public key can be shared with anyone, while the owner must keep the private key secret. 

b) Speed: Symmetric encryption is faster and easier to use than asymmetric encryption but less secure. If the secret key is compromised, the data can be easily decrypted. Asymmetric encryption is slower and more complex than symmetric encryption but more secure. Even if the public key is known, the data cannot be decrypted without the private key. 

c) Usage: Symmetric encryption is used when a large amount of data must be transferred securely and when the secret key can be safely exchanged between the sender and the receiver. For example, symmetric encryption is used to encrypt the data in a VPN connection. Asymmetric encryption is used when a small amount of data is required to be transferred securely and when the public key can be easily distributed to anyone. For example, asymmetric encryption encrypts the digital signatures in an email.

18) Please define UDP and TCP and discuss their differences. 

UDP and TCP are two protocols to send data across the internet. They are part of the internet protocol suite, which defines the rules and standards for data communication. UDP and TCP differ in the following aspects: 

a) Reliability: TCP is a reliable protocol that ensures that the data is delivered correctly and completely to the destination. TCP uses a mechanism called acknowledgement, which confirms that the data has been received. TCP also uses retransmission, which resends the data if lost or corrupted. UDP is an unreliable protocol, meaning it does not guarantee that the data is delivered correctly and completely to the destination. UDP does not use any acknowledgement or retransmission mechanism and simply sends the data without checking for errors or losses. 

b) Connection: TCP is a connection-oriented protocol. It establishes a connection between the sender and receiver before sending the data and maintains the connection until the data transfer is completed. TCP uses a mechanism called a three-way handshake, which exchanges information and agrees on the parameters for the connection. UDP is a connectionless protocol that does not establish or maintain any connection between the sender and receiver. UDP simply sends the data as individual packets without any coordination or synchronisation. 

c) Order: TCP is an ordered protocol, meaning it preserves the order of the data sent. TCP uses a sequence number mechanism, which assigns a number to each packet and arranges them in the correct order at the destination. UDP is an unordered protocol, which means it does not preserve the order of the sent data. UDP does not use any sequence number, and the packets may arrive in any order or even out of order at the destination. 

d) Overhead: TCP is a heavy protocol, which means it adds a lot of overhead to the sent data. TCP has a larger header size, which contains more information and fields for the connection, acknowledgement, retransmission, and sequence number mechanisms. TCP also consumes more bandwidth and resources, as it has to maintain the connection and handle the errors and losses. UDP is a light protocol, which means that it adds a little overhead to the data that is sent. UDP has a smaller header size, which contains less information and fields for the connectionless and unreliable mechanisms. UDP also consumes less bandwidth and resources, as it does not have to maintain the connection or handle the errors and losses.

19) What is WEP cracking? What are the types of WEP cracking?

WEP cracking breaks the security of a wireless network that uses the Wired Equivalent Privacy (WEP) protocol. WEP is an outdated and weak protocol designed to provide the same level of security as a wired network, but it has many flaws and vulnerabilities that make it easy to crack. There are different types of WEP cracking, such as: 

a) Passive cracking: This type does not affect the network traffic until the WEP key is cracked. It involves capturing many packets containing the initialisation vector (IV) and the encrypted data and then using a tool such as aircrack-ng to perform a statistical analysis and recover the key. This method is difficult to detect, but collecting enough packets may take a long time. 

b) Active cracking: This type of cracking affects the network traffic by injecting or replaying packets to generate more IVs and encrypted data and then using a tool such as aircrack-ng to perform a statistical analysis and recover the key. This method is faster than passive cracking but may be detected by the network administrator or the Wireless Intrusion Detection System (WIDS). 

c) Fake authentication attack: This type of cracking involves impersonating a legitimate client and associating with the Access Point (AP) using a fake MAC address and a fake authentication request. This allows the attacker to capture the challenge and response packets used for authentication and then use a tool such as aircrack-ng to perform a brute force attack and recover the key. This method is also faster than passive cracking, but the network administrator or the WIDS may detect it. 

20) List out various WEP cracking tools?

WEP cracking tools are software applications or devices that perform WEP cracking. Some of the popular WEP cracking tools are: 

a) Aircrack-ng: This suite of tools can perform various attacks on wireless networks, including WEP cracking. It can capture, analyse, and inject packets and use statistical techniques to recover the WEP key. It can also perform fake authentication, de-authentication, and fragmentation attacks. 

b) Kismet: This is a wireless network detector, sniffer, and intrusion detection system that can capture and analyse packets from wireless networks, including WEP networks. It can also detect hidden networks, rogue APs, and network intrusions. 

c) Wireshark: This network protocol analyser can capture and examine packets from various networks, including wireless networks. It can decrypt WEP packets if the key is known and display the plain text data. 

d) Fern WiFi Cracker: This Graphical User Interface (GUI) tool can perform various attacks on wireless networks, including WEP cracking. It can also perform WPA/WPA2 cracking, MAC spoofing, session hijacking, and brute force attacks.
