Cyber Security Interview Questions

Most Frequently Asked Top Cyber Security Interview Questions

1. What is meant by Cybersecurity?

Ans. Cybersecurity is the practice of securing systems, networks, programs, and crucial data from digital or cyber-attacks. In computing language, cyber security protects against unauthorized system access.

2. What is Cryptography?

Ans: Cryptography is a technique that is used to protect information against third parties referred to as adversaries. Cryptography enables both the sender and the recipient of a message to read the details of the message.

3. Describe the terms Threat, Vulnerabilities, and Risks.

Ans: 

• Threat: A threat is something that has the potential to cause harm to your organization.
• Vulnerabilities: They are the weak areas of the system which will be able to be exploited by the cyber-criminal.
• Risk: Risk refers to the damage that exploitation of vulnerabilities can cause to the organization.

4. List some common types of cyberattacks a company may face?

Ans: The cyberattacks most likely to affect a company are:

• Malware
• Phishing
• Data leaks
• DDoS attacks
• Ransomware
• Brute-force attacks

5. What does the MITM attack mean?

Ans: MITM (Man-in-the-middle) is a kind of attack in which an attacker enters in between the communicating parties and steals the information.

We can prevent MITM attacks by following these methods:

• Using VPN
• Using strong WEP or WPA encryption
• Using Intrusion Detection Systems
• Forcing HTTPS
• Using Public Key Pair Based Authentication

6. What is port scanning?

Ans: Port scanning is the technique that is used for identifying open ports and the service available on the host. Port scanning is used by Hackers to search for information that may be useful to exploit vulnerabilities. Port Scanning is also used by Administrators for checking network security policies. Commonly used port scanning techniques include:

• UDP
• Ping Scan
• TCP Connect
• TCP Half-Open
• Stealth Scanning

7. What are Cybersecurity elements?

Ans: Main cyber security elements include:

Information security: Information security involves data protection like customer data, employee login data, and any other data that is essential to the business, like intellectual property data and software development codes.

Network Security: The aim is to protect your company's network like Wi-Fi and Internet from hackers. This is also known as perimeter security.

Application Security: Companies require a secure application for protection against cyber attacks.

End-user education: To have a strong cybersecurity measure in a company, it is essential to educate all employees on cybersecurity. They must be aware of different cyber security threats and the way they can address them.

Operational Security: It is used for the protection of the functions of the company and monitors vital information to detect gaps in the current methods. Business continuity planning is the analysis of the way operations could be affected by a cyber-attack and the way companies can overcome that kind of attack without a significant impact on the business operations.

Leadership commitment: Without proper leadership, the development, implementation, and maintenance of a cybersecurity program will become challenging.

8. What is the primary purpose of cyber security?

The protection of data is the primary goal of cybersecurity. The security department offers a triangle of three connected concepts to safeguard data against hackers. The CIA trio is the name given to this idea. The CIA model includes the concepts of availability, integrity, and confidentiality. It is a security paradigm that leads people through a variety of IT security-related issues. The CIA model was created to help organisations create policies for the design of their information security architecture. When a security breach was discovered, one or more of the security principles had been broken.

9. What is the CIA?

Insofar as it forbids unwanted access to the data, confidentiality is comparable to privacy. The objective is to prevent unauthorised users from accessing data and to ensure that only authorised users can utilise it. By doing this, important information is kept out of the wrong hands. A great privacy example is encrypting data.
