Introduction

Before getting into Cybersecurity Basic Interview Questions will put light on what cybersecurity is.

Cybersecurity is the process of protecting internet-connected systems such as servers, mobile devices, networks, computers and many more. 

Did you know? – Cybersecurity can be broken into two parts, i.e. cyber and security. Cyber refers to vast technology that includes networks, data, programs and systems. Security, on the other hand, is meant to protect these technologies. 

Cybersecurity is also known as information technology security or information security. As per the prefined author, Cybersecurity is “A set of technologies, processes and practices aimed at preventing attacks, theft, damage, modification or unauthorised access to networks, devices, data and programs.”

In layman’s language – Cybersecurity refers to the techniques and concepts meant to protect computing resources and internet information against hackers.

As you know the meaning of Cybersecurity, let us pass on the primary question that will be asked during the interviews.

Cybersecurity Basic Interview Questions

1. Mention the essential objectives of Cyber Security

As this is a security sector, it offers a cycle of three connected objectives. The name for this important objective is called “CIA Trio.” This objective is intended to develop security architecture and information policies. 

CIA stands for Central Intelligence Agency; in Cybersecurity, it stands for Confidentiality Integrity Availability.

Objectives of Cybersecurity

2. What is the difference between threat, vulnerability and risk?

Threat: It is a hazard that can steal or destroy data, cause harm in general, and disrupt operations. Some examples of threats are phishing, malware, data breaches, and black hat hackers.

Threats are people who want to inflict damage on organisations, companies, or even ordinary people.

Vulnerability is a hardware/software/procedures flaw hackers use to achieve their goals. Some examples of vulnerabilities are exposing networking equipment, human vulnerabilities and phishing assaults.

Vulnerabilities management is identifying, analysing, reporting and correcting the vulnerabilities. 

Risk: The probability of combining both vulnerability and threat is called a risk. To calculate risk, there is the formula, 

Risk = Likely threat * Vulnerable Impact

Risk management is finding the upcoming hazards, analysing the threat and determining the best course of action.

3.  What is Firewall?

It is the barrier between the internet and LAN (Local Area Network). It helps to reduce security threats and make private resources remain confidential. So, it manages both inbound and outbound network traffic.

4. What is VPN?

VPN stands for the virtual private network. It enables you to connect to a private network, establishing encryption to hide the user’s IP address (Internet Protocol address). This encrypted connection aids in the secure transmission of sensitive data. It protects against illegal rules over traffic and allows the user to work remotely.

5. Who are White, Black and Grey Hat Hackers?

White hackers are ethical hackers. These hackers never intend to harm anyone or steal any information. They put a solid thrust to uncover the loopholes in the network system or computer.

It is considered to be the most challenging job in the IT business. Not only Fortune 500 companies need it but also semi-grown companies for vulnerability assessment and penetration tests.

Black hat hackers are unethical hackers who attempt to obtain unauthorised access to a network, disrupt operations, or steal confidential information.

Lastly, Grey hat hackers have the skills to hack ethically and unethically. They exploit security flaws in a network or computer without the company’s permission. Their total goal is to draw attention from the owners and receive gratitude or reward.

6. Name the types of Cybersecurity?

In every company, a variety of various systems are presented. Here are the essential cybersecurity types which coordinate across the actions.

  • Network Security
  • Application Security
  • Data Security
  • Operational Security
  • Cloud Security
  • Mobile Security
  • Identity Management

7. What do you mean by Honeypots?

Honeypot is a decoy attached to a network system to lure cyber attackers and defects. The honeypot is to represent itself on the internet as a potential target for hackers. This is used when the server is a high-value asset. 

In simple words, the honeypot is like a duplicate safe box with no info but projects to be the one with information and locks hackers. 

8. What is Phishing?

Phishing is a crime in which the hacker looks for legitimate entities like financial institutions. They send a link to the target(users) by email or phone text. If the user clicks on the link, they will be taken to a fake website that looks legitimate, and malware is installed on their pc. This website will ask for all the sensitive information like bank, personal or credit card info. The target becomes the victim, and the hacker will remotely control them to scoop the data or money from them.

9. What do you know about two-factor authentication?

Two-factor authentication, also known as 2FA. It is a security method to identify using two independent, authentic factors. This procedure was introduced in April 2018 to protect the user’s credentials and resources that the user accesses. This authentication process makes it more challenging to get access to personal devices or online accounts.

10. Differentiate between Symmetric and Asymmetric Encryption?

Symmetric EncryptionAsymmetric Encryption
Encryption and DecryptionCan be done using 1 keyNeed a different key for each.
TechniqueEncryption is fastEncryption is slow
Transform of DataWhen the data is hugeWhen the data is small
ResourcesUses more resources when compared to asymmetricUses fewer resources
CiphertextSmaller text or plain textGreater than plain text
