Introduction to IT Security Interview Questions and Answers

Web development, programming languages, Software testing & others

So people should need to be more aware of common security purposes and day-by-day updates on security awareness so that avoiding any hacking activity smoothly without any big impact. This kind of security concern is not only specific technical concerns, but they also have a lot of Security bridges in case of personal or business points of view. One of the most significant security leakage possibilities is in an email, where our normal attitude is to attach important information and send it through the network. IT security guys normally suggest two approaches: one specific encryption mechanism and encrypting secure data before sending it through the network. Otherwise, maintain everything in the internal secure network, not moving outside a secure network anytime. This kind of encryption security normally uses a public and private key utility, where a public key has been shared between sender and receiver. The specific encryption tool maintains one secret private key

Now, if you are looking for a job related to IT Security, you need to prepare for the 2023 IT Security Interview Questions. Every interview is indeed different as per the different job profiles. Here, we have prepared the important Interview Questions and Answers to help you succeed in your interview.

This 2023 IT Security Interview Questions article will present the 10 most important and frequently asked IT Security interview questions. These top interview questions are divided into two parts as follows:

Part 1 – IT Security Interview Questions (Basic)

This first part covers basic Interview Questions and Answers.

Q1. Provide some examples and details regarding the encryption of email transmission.

One of the popular software for encrypting email transmission is PGP (Pretty Good Privacy). This software is very popular for encrypting email data smartly to avoid data leakage uncertainty. It is not only useful to encrypt mail bodies, rather than it can be very popular for signing, encrypting, or decryption features for physical files, normal text, full directories, attached data, and even whole data partitions as well. As all the big companies are very concerned about hiding or encrypting their specific communication, PGP is one of the common choices for them to use in any communication. The main utility of PGP is using a secret private key which is only known to the tool, and one shareable public key which is available for both sender and receiver. So the receiver can easily identify or verify the sender’s secure identity to confirm the sender person’s security and verify the proper integrity of the content shared by the sender. The receiver can effortlessly understand whether someone in the network root has tampered with the mail or not.

A process of encryption & Decryption of PGP (Pretty Good Privacy):

Data – Generate Random Key – Encrypt data using this random key – Encrypt random key by receiver public key (X1) – encrypt random key by sender public key (Y1) – Send encrypted data to the receiver.

Encrypted Data – Decrypt  X1 by receiver private key – Decrypt encrypted data by decrypting the result of X1 (the random key of earlier encryption) – display to the receiver.

Q2. What will be the secure access process in case of remote device access from your system? Q3. Explain the specific approach or process that can be taken to hide the message in the case of IT Security.

One critical IT or network security approach involves the sender writing their text using a specific encryption method, and the receiver decrypting the content using a straightforward decryption approach defined by the sender and known only to the receiver. This kind of security usually is called a packet-sending approach.

Q4. Define clearly Social engineering attack (SEA).

These are the common IT Security Interview Questions asked in an interview. Social Engineering Attack is sometimes very dangerous and a little easy for a hacker to use the same. It mainly depends on human interaction, which means gathering any personal details by purely illegal integration and manipulating their data easily and use for their gain. This is one of the biggest threats in the last couple of years. And it is very easy to break as this kind of hacking does not require an expert to break network or critical security. Any non-technical person can able to do the same.

Q5. Explain proper risk when planning to use public Wi-Fi available in the airport or railway station.

The possibility of a hacking password, personal information, credit card data, etc.

Part 2 – IT Security Interview Questions (Advanced) Q6. Explain in detail why people say MAC OS is more reliable than others.

As it runs on Apple computers.

Q7. Provide one proper explanation of what a firewall is and what it will be the use of it. Q8. As a common person, explain some secure processes to avoid identity theft.

Always maintained strong and secure identification security information and not sharing personal data with anyone.

Let us move to the next IT Security Interview Questions.

Q9. One of the big questions for the entire web user is whether social media is secure for sharing personal data.

No, not at all. Better not to share any personal things.

Q10. Explain in detail about data leakage.

One can explain any data movement from a specific organization that lacks proper organization as data leakage.

Web development, programming languages, Software testing & others

Question and Answers

Let us discuss questions and answer about Linked List Interview Questions.

1. What is linked list?


Linked list is a data structure which is linear in nature and does not stores the data in the sequential memory locations. A linked list consists of one or more nodes also called as links.

2. Tell about the graphical representation of linked list.

Each link is a pair of two things one is the data part which holds the value of the element which needs to be stored in the linked list while the second part is the next which stores the address of the next link or node to which it pints to. The starting node or link is known as the head. The last node has its next part pointing to the null as there is no further node to be pointed which marks the end of the linked list as shown in the below figure.

As shown above each node contains the data field and the reference field. A linked list can contain any number of nodes depending on the data which we need to store and the memory capacity that is available.

3. How many linked list types are present?


There are following types of linked list:

• Circular Linked List

4. Describe the singly linked list.


The answers of first and second combining can be referred for this question’s answer.

5. Describe the doubly linked list.


In doubly linked multiple links or nodes are connected to each other and each of the node contains three field in it namely prev, data, and next containing the pointer to previous node, the data of the element, and the pointer to next element respectively. The graphical representation of the doubly linked list is as shown below –

6. Describe the circular linked list.


The following figure shows the visual representation of the working of the circular queue and the way in which the data is stored in it.

7. What type of memory allocation is used in implementation of linked list?


Dynamic memory allocation is used in linked list.

8. What is meant by traversing the linked list?


9. Specify the differences that exist between the linear array and linear linked list.


Linear Array

Linked List

Difficult for insertion and deletion No movement of nodes required to perform insertion and deletion.

Space is wasted as fixed size needs to be specified priorly. No wastage of memory due to dynamic memory allocation.

Same amount of time is required for availing different elements stored in array. Different amount of time is required for availing different elements stored in array.

Elements are stored consecutively. Elements may not be stored consequently.

Direct access to required node is done. Traversing of all the prior nodes needs to be done for reaching particular node.

10. What are applications of the linked list data structure?


Stacks, queues, skip unrolled linked list, binary tree, hash table, etc. are some of the applications of linked list.


• No specification of the fixed size required as memory is allocated dynamically in runtime according to requirement.


• Sequential access of the data needs to be done resulting in not able to use binary search which is why we cannot perform random access in linked list.

• More memory required for storing the pointer addresses.

• O(n) time complexity for accessing the element which results in slow performance due to recursion.

13. From where we bring the free node while performing the insertion operation of linked list?


Avail list

14. Name the header list which has the last node pointing to null pointer.


Grounded header list.

15. Which package is used in java programming language for implementing the linked list?


Java.util package.

16. In java, which interfaces implement the linked list?


The following interfaced implement linked list in java –

• Collection

17. Tell me about the process of adding the two linked list with the help of stack using java programming language.


The resultant linked list can be filled with the values in such a way that the sum of first element in first linked list will be done with the first element of the second linked list and the resulting value will be inserted in the first element for the resultant linked list. The same process will be carried out for the other elements of the linked list as well. If both the list are not of same length then the remaining elements of the longer list will be copied directly to the resultant list at the end of carrying out the sum for previous elements as explained previously.


You should be aware about all the basics of linked list and its working in order to prepare for interview. For the same thing, it is necessary that you go through all the above-mentioned questions and answers and clear yourself with the structure, working, and implementation of linked list data structure.

To help you prepare, we have compiled a list of the top 2023 Data Structures and algorithms interview questions and answers.

Part 1 – Data Structures And Algorithms Interview Questions for Freshers 1. What is a data structure?

A data structure is a way of organizing, storing & retrieving data in a structural & systematic manner. It also defines their relationship with one another through algorithms. A data structure contains a variety of data items to perform various applications. This performance is highly specialized for specific tasks.

2. What are the various data structures available?


The various data structures available are lists, arrays, stacks, queues, graphs, trees, tables, records, etc. The availability of data structure depends on the programming language.

3. What is an algorithm?

An algorithm is a step-by-step method to solve a problem. It defines a set of instructions that must be executed to get the desired result. For example, a computer program uses an elaborate algorithm. An algorithm is not the entire code. It is simple logic (solution) to a problem represented using a flowchart or pseudocode.

4. Differentiate file structure from the storage structure.


5. What is a linked list?

A linked list is a collection of elements linked by pointers or references. Tips help to connect the elements to form a chain. A node is a distinct object of each element. A linked list is a data structure consisting of a group of nodes representing a sequence together.

6. What is the stack?

A stack is a type of Abstract Data Type (ADT). We use the Stack data structure to store and retrieve values using the Last-In-First-Out (LIFO) algorithm. A stack is a data structure where insertion and deletion occur at a particular time.

7. Why do we use stacks?

A stack structure dramatically restricts how elements are inserted, retrieved, and removed. Only the most recently inserted element in the stack is retrieved or removed. Stacks follow the LIFO method; adding and retrieving a data item takes only O(n) time. It is used in accessing data in the reverse order in which it arrived. It is frequently used in recursive function calls, expression parsing, depth-first traversal of graphs, etc.

Part 2 – Data Structures And Algorithms Interview Questions for Experience 8. What are the operations performed on stacks?

The primary operations performed on a stack are as follows:-

pop() − removes the top stack item -Deletion.

peek() − returns a value of a top item without removing it -Traversal.

isempty() − checks if the stack is empty –Null check.

isfull() − checks if the stack is full –No space.

9. What is a queue in the data structure?

The queue is a linear data structure storing items and opening at both ends. One end serves to enqueue (insert an element), and the other serves to dequeue (remove an element). The First-In-First-Out methodology governs the Queue, meaning that the first data item stored is the first to be made available.

10. What is linear searching? 11. What is a binary search?

A binary search applies to already sorted lists or arrays. Binary search, also known as half-interval search, logarithmic search, or binary chop, is a search algorithm that finds the position of a target value within a sorted array. This search selects the middle, dividing the entire list into two sections, and compares the middle part first.

12. What is a graph?

A graph is a pictorial representation of a collection of objects. A graph is a non-linear data structure consisting of nodes and edges. The points that connect the interconnected objects are vertices, and the links that connect the vertices are edges. A graph data structure contains a finite (potentially mutable) set of vertices, nodes, or points. In an undirected graph, we use a set of unordered pairs of vertices, while in a directed graph, we use a set of ordered pairs.

13. What is a recursive function?

A recursive function is one that either directly calls itself or calls a function that, in turn, calls itself. Recursive algorithms solve problems by breaking them into simpler sub-problems and solving them iteratively. The output of one operation is the direct input for the next iteration operation.

14. What is the tower of Hanoi?

The Tower of Hanoi is a mathematical puzzle consisting of three towers (pegs) and multiple rings. All rings are of different sizes and stacked on each other, where the large disk is always beneath the small disk. The aim is to move the tower of a disk from one peg to another without destroying its properties. The main objective is to move the disks one by one from the first to the last peg but cannot stack two discs on top of each other.

15. Give some examples of greedy algorithms?

The greedy algorithm approach is used to solve the problem listed below:−

Traveling Salesman issue

Prim’s Minimal Minimal Spanning Trees

Kruskal’s Minimal Minimal Spanning Trees

Dijkstra’s Minimal Spanning Tree Algorithm

Graph – Map Coloring

Graph – Vertex Cover

Knapsack issue

Job Scheduling Problem
