I think that was one of the biggest moments that I noticed in my life.”

13. What is Cryptography?

It is a technical question, so the interviewer over here wants to know your knowledge. Be precise and give answers in a few lines.

“Cryptography is the discipline and study of ways for securing information and communication, to protect data from third parties who aren’t supposed to have access to it.”

14. What is the Difference Between IDS and IPS?

Simply define the definitions over here and don’t go into the details. Make it concise.

“IDS stands for Intrusion Detection System, and it merely detects intrusions, leaving the administrator to deal with the prevention. In contrast, in an IPS, or Intrusion Prevention System, the system detects the intrusion and takes action to prevent it.”

15. How is Encryption different from Hashing?

Encryption and Hashing are the ways to encrypt the data and protect it. Define both.

“To turn readable data into an unreadable format, both encryption and hashing are employed. The distinction is that encrypted data can be decrypted and converted back to original data, whereas hashed data cannot be converted back to its original form.”

16. What Is NSTISSC Security Model?

The NSTISSC is a National Security Telecommunication document that defines a model of information security. So the precise answer to this question will be:

“This is a reference to the document titled “The National Security Telecommunications and Information Systems Security Committee.” This document lays forth a thorough information security model. There are three dimensions to this model.”

17. What’s The Difference Between Symmetric And Public-Key Cryptography?

This question will be normally asked for the positions of GRC Consultant, SOC Analyst, Cloud Security Architect, and Data Protection Officer. You should have an understanding of cryptography to explain this concept. The best answer to this question is:

“A shared key between two parties is used in symmetric key cryptography. Asymmetric key cryptography employs a public-private key pair, with one key encrypting and the other decrypting data.”

18. Which Types Of Encryption Does Symmetric Key Encryption Use?

There are two types of Symmetric Key Encryption. Define both.

“One of the following encryption types are used in symmetric key encryption:

1) Stream ciphers: encrypt a message’s digits (usually bytes) or letters (in substitution ciphers) one by one.

2) Block ciphers: encrypts a group of bits as a single unit and then adds the plaintext to make the total size of the block a multiple of the block size. 64-bit blocks were regularly utilized. The Advanced Encryption Standard (AES) algorithm, authorized by the National Institute of Standards and Technology in December 2001, and the GCM block cipher mode of operation both use 128-bit blocks.”

19. What Are Three Ways To Authenticate Someone?

There are three types to authenticate someone. Define each of them over here.

“Something you know, something you have, and something you are the three sorts of authentication factors.

A password, a PIN, or the answers to a security question are all examples of something you know. This is one of the most prevalent methods for users to access their accounts. An authenticating device, such as an ID card or a cell phone, is something you have. Biometric information is something you are. A fingerprint, a voice password, or a signature can be used. This type of authentication is more difficult to obtain offsite, but it is also the most difficult to forge. 

When you utilize two of these ways to access an account, it’s known as two-factor authentication. To log in, a user may be required to input their password, and then a code texted to their phone. When all three methods are used, it is called multi-factor authentication.

20. What Is The Difference Between Data Protection In Transit And Data Protection At Rest?

“Data protection at rest refers to the securing of data while it is in storage. Attackers can access this data if they get physical or digital access to the storage device on which it is stored.

Data protection in transit refers to the security of data sent via a network, such as an internet.

Security measures such as firewalls and network access control help to protect both of these sorts of data. Both forms of data should be encrypted as well. If an attacker gains access, they will be unable to read the data unless they break the encryption.”
