About Cyber Security

Before moving to the topic, we believe that you must have an idea about what is cyber security. Cyber Security is a very beneficial program in protecting computers, servers, electronic systems, and data from attacks. Cyber means technical appliances like computers, networks, and programs, and security means securing all those devices. Cyber Security is a set of fundamental processes in preventing attacks, damage, and unauthorized access to a particular network

Importance of Cyber Security

After understanding cyber security, you must have an idea about the importance of cyber security. Cyber security is a platform made to protect our electronic gadgets. It is the platform used in multiple areas, including banking, financial institutions, the government sector, and the other regions, to make devices more secure and safe.

Mostly Asked Cyber Security Interview Questions For Freshers 2022

Now that you have a basic knowledge about Cyber security so now it’s time to review all the Cyber security interview questions for freshers in 2022 that are mostly asked in the Interviews.

1. What is Cybersecurity?

Cybersecurity is the practice of protecting computer networks, systems, and data from malicious attacks. It includes designing, implementing, and maintaining security technologies, policies, procedures, and practices to prevent and detect cyber-attacks. 

2. What can you do to prevent Cross Site Scripting?

To prevent cross-site scripting, we should follow several practices such as using an XSS filter, encoding special characters, using anti-XSS services/tools, and validating user inputs.

3. Mention the difference between Threat, Vulnerability, and Risk.

A threat is when someone can cause harm to the system by damaging or destroying it. The team was commonly known as a Phishing attack.

 On the other hand, 

A vulnerability is a weakness found in a system that can lead to threats. Security professionals know how important it is to be aware of potential threats and vulnerabilities. And when you’re not, you may be the one who gets hacked. 

Last but not least, A risk refers to the damage that can be done to the data if or when a threat exploits the already present vulnerability.

4. What is the best way to strengthen user authentication?

You can strengthen your user authentication by using the below methods:

Two-factor authentication: Two-factor authentication requires the user to have two forms of identification to log into a system. This makes it harder for hackers to gain access to your system.

Good password policy: You should also use strong passwords and change them regularly. You can use a password manager to help you create strong passwords.

One-time passwords: These are random codes that users must enter before logging in to the system.

Password changes: You can change a user’s password frequently. This is an excellent way to ensure that users are not using the same password.

5. What is the difference between Asymmetric and Symmetric encryption?

Asymmetric and symmetric encryption are two different ways to encrypt data. Asymmetric encryption uses a public key to encrypt data and a private key to decrypt it and is the most common way to encrypt data.

However, it has some drawbacks as the public key is widely known, anyone can use it to encrypt a message, but only the person holding the private key can decrypt it.

On the other side, Symmetric encryption uses a single key to encrypt and decrypt messages. This method is more secure than asymmetric encryption because a single key is used to encrypt and decrypt the data, and only the person with the key can decrypt the message.

6. What is CSRF?

Cross-Site Request Forgery (CSRF) is a common form of attack in which a malicious site can force a victim’s browser to execute unwanted commands on a legitimate site. The attacker aims to trick users into performing actions that compromise their accounts.

7. What is cognitive security?

Cognitive security is primarily an application of AI technology that identifies threats and protects the physical and digital systems. It is based on human understanding processes.

8. Importance of DNS monitoring?

The DNS is the most critical component of a website’s online presence. It is the gateway to all information about your site, including its IP address, name, and location. DNS monitoring is essential for several reasons.

It allows you to identify and resolve issues with your DNS before they can cause problems for users on your network. Moreover, it helps you keep track of any changes made by malicious actors that could negatively impact your network’s security or allow them to take control of certain aspects of it.

9. What are Black hat, White hat, and Grey hat hackers?

There are three types of hackers: Black Hat, White Hat, and Grey Hat.

  • Black Hat hackers are malicious hackers who seek to obtain sensitive information, disrupt the operations of a network, or cause damage to a system.
  • White Hat hackers are good guys concerned with protecting their customers’ data and systems.
  • Grey Hat hackers don’t care about their victims; they are just after money.

10. What is a CIA triangle?

The CIA created the CIA triangle to illustrate how to protect the US from foreign threats. It is a 3-dimensional illustration that illustrates the relationship between three elements: Intelligence, Operations, and Communications. The CIA triangle is a helpful tool for illustrating how to protect your company from cyber attacks and other threats.

11. What is Cryptography?

Cryptography is a process of protecting information from third parties for whom the information is not made. Multiple techniques or programs are used to protect such information in this method.

12. What is the primary goal of cybersecurity?

As we have discussed that cybersecurity is a process of protecting data from unauthorized attacks. The CIA model lets the organizations develop such policies, which are very beneficial in protecting information. CIA stands for confidentially, integrity and availability. 

• Confidentially: It is a set of tools that work the same as privacy and protect authorized access to the data. It lets the data access all those authorized to use it while restricting the others.

• Integrity: Integrity is the process which focuses on protecting unauthorized access. In other words, it is the method that lets the data get the data only used by those who are authorized to use that.

• Availability: The processes ensure that the information will be regularly available to get access. It checks for the system’s performance while ensuring that it must work properly.

13. What are the various advantages of cyber security?

There are many advantages of choosing cyber security. A few of them are:

Beneficial in protecting a system from cyber attack and problems related to the data breach
