Top Cybersecurity Interview Questions
Cybersecurity is the only IT area that hasn’t experienced a recession. There is always competition. It is crucial for managing data breaches, effectively protecting sensitive data, and reducing risks. Although possessing the necessary Cybersecurity skills is a first step, it is not enough to pass the interview. Questions and answers for Cybersecurity interviews to help you pass the interview.
1: What is Cybersecurity?
Cybersecurity concerns preventing hackers access to electronic data on websites, networks, and devices. Cybersecurity experts help maintain data security and accessibility using cutting-edge technology as well as complex procedures.
2: What skills are required for a Cybersecurity professional.
Cybersecurity professionals need to be able to understand network security and mitigate endpoint threats. A Cybersecurity professional must be able to understand cloud server security and computer networks.
3: Define hacker?
Hackers are individuals who attempt to hack into a computer system. Hacking can be used for many purposes, including installing malware, stealing data, or disrupting services.
4: What is Cryptography?
“Cryptography” is a Greek term that means “hidden.” Cryptography is the study of secure communication methods such as encryption that limit access to message contents to the intended receiver and sender.
5: What is the most common Cyberattack type?
Phishing attacks are the most popular Cyberattack. They are simple to carry out and can be quite powerful.
6: What is a 3-way handshake?
A three-way handshake, also known as TCP-3way Handshake, is a method to establish a connection between client and server over a TCP/IP network. This mechanism allows the client and server to send each other the acknowledgment and synchronization packets before any actual data transmission takes place.
7: Create a firewall.
A firewall is a program that filters outgoing and incoming traffic networks using a set of rules. The goal of a firewall is to prevent or reduce undesirable network communications and allow lawful communication to continue without interruption.
8: How do I configure a firewall?
Username/password: Change a firewall device’s default password
Remote management: Disable remote administration.
To ensure that certain applications like a web server and FTP server work effectively, you must configure correct port forwarding.
Server for DHCP – In the absence of disabling firewall’s DHCP, installing a firewall on a network with a DHCP service will create a conflict.
Logging: Make sure logging is enabled. Learn how to view logs and fix firewall problems.
Policies: Make sure the firewall is properly configured to enforce security regulations. Strong security policies are also important.
9: What function does an antivirus sensor system serve?
Antivirus software detects, stops, and removes viruses from computers. Most antivirus programs are installed in the background and provide real-time protection from Cyberattacks.
10: What is security auditoring?
Security auditing is one of the best ways to protect a system’s integrity. The overall security plan should include a component that establishes the appropriate level of auditing for your environment.
11: How does encryption and hashing differ?
There are two distinct purposes for encryption and hashing. While hashing converts data into a message digest that is irreversible, encryption includes both the encryption process and the decryption process.
12: What is a VPN?
A virtual private network (or VPN) is a service that helps you to protect your online privacy. A VPN connects your computer with the Internet in a secure and encrypted manner.
