Cyber Security Interview Questions and Answers
Question - 41 : - How to make the user authentication process more secure?
Answer - 41 : -
In order to authenticate users, they have to provide their identity. The ID and Key can be used to confirm the user’s identity. This is an ideal way how the system should authorize the user.
Question - 42 : - Explain the concept of cross-site scripting.
Answer - 42 : -
Cross-site scripting refers to a network security vulnerability in which malicious scripts are injected into websites. This attack occurs when attackers allow an untrusted source to inject code into a web application.
Question - 43 : - Name the protocol that broadcast the information across all the devices.
Answer - 43 : -
Internet Group Management Protocol or IGMP is a communication protocol that is used in game or video streaming. It facilitates routers and other communication devices to send packets.
Question - 44 : - How to protect email messages?
Answer - 44 : -
Use cipher algorithm to protect email, credit card information, and corporate data.
Question - 45 : - What are the risks associated with public Wi-Fi?
Answer - 45 : -
Public Wi-Fi has many security issues. Wi-Fi attacks include karma attack, sniffing, war-driving, brute force attack, etc.
Public Wi-Fi may identify data that is passed through a network device like emails, browsing history, passwords, and credit card data.
Question - 46 : - What is Data Encryption? Why it is important in network security?
Answer - 46 : -
Data encryption is a technique in which the sender converts the message into a code. It allows only authorized user to gain access.
Question - 47 : - Explain the main difference between Diffie-Hellman and RSA.
Answer - 47 : -
Diffie-Hellman is a protocol used while exchanging key between two parties while RSA is an algorithm that works on the basis two keys called private and public key.
Question - 48 : - What is a remote desktop protocol?
Answer - 48 : -
Remote Desktop Protocol (RDP) is developed by Microsoft, which provides GUI to connect two devices over a network.
The user uses RDP client software to serve this purpose while other device must run RDP server software. This protocol is specifically designed for remote management and to access virtual PCs, applications, and terminal server.
Question - 49 : - Define Forward Secrecy.
Answer - 49 : -
Forward Secrecy is a security measure that ensures the integrity of unique session key in event that long term key is compromised.
Question - 50 : - Explain the concept of IV in encryption.
Answer - 50 : -
IV stands for the initial vector is an arbitrary number that is used to ensures that identical text encrypted to different ciphertexts. Encryption program uses this number only once per session.
