The questioner evaluates candidates' capabilities from fundamental principles to advanced topics. Given are some most asked interview question and their answers-
Let's start
The first step is to begin with some basic cybersecurity interview questions for freshers.
Cryptography in cybersecurity refers to the process wherein information is coded or hidden. This ensures that only the person for whom the message was for can decode/ read it.
Traceroute is basically an impactful network diagnostic tool. It enables users to track down the path taken by data packets, right from the source to the destination over the internet.
The CIA triad stands for confidentiality, integrity & availability. This security model is used by organizations to ensure IT security.
In cyber security, a firewall is basically a wall that tracks all outgoing and incoming traffic to block hackers from performing any malicious activity. It helps in maintaining data privacy from phishing links, trojan viruses, worm viruses, etc.

Here is a list of the OSI model layers
Risk management is a crucial process in the cyber security field. It entails identifying potential threats, analyzing their impact and constructing the best plan of action. This never-ending process is possible by understanding risk, which itself is the product of threat and vulnerability.
A botnet is an accumulation of internet-connected devices that get infected with malware and can even be controlled by it. These can be mobile phones, servers and PCs. It is extensively used for stealing data, launching distributed denial-of-service attacks (DDoS), sending spam and much more.
XSS is the short form of cross-site scripting, which is a web security flaw that leaves a gap for an attacker to manipulate and determine how users interact with the susceptible app.
Preventing is both simple and easy, swayed by the app's sophistication and user-controllable data handling. These are some ways to prevent it

Patch management must be implemented as soon as any software updates are released. It is imperative for all network devices present within an enterprise to undergo in less than a month.
DDoS is the acronym of distributed denial-of-service, which is an attack that overwhelms the target network, system or site with excessive traffic flow. This renders the target inaccessible to its target users.
It happens mainly in two ways
Data leakage describes unauthorized release of information or data to a third party from the business' end. It can happen through storage devices, email, internet or mobile data. Three types of data leakage are

A honeypot refers to a network-attached system that is implemented as a decoy to attract cyberattacks. This helps the cybersecurity team in detecting the attackers, deflecting them and studying the hacking attempts.
Brute force attack in cyber security is a hacking method. It employs trial and error to crack encryption keys, login credentials and passwords. This simple yet effective tactic helps many attackers gain unauthorized access to organization's networks and systems and individual's accounts.
Brute force reflects the brutal ways and force used to get into the user accounts.
Address Resolution Protocol (ARP) is the network layer's communication protocol in the OSI (open systems interconnection) model. It paves a bridge between a fixed physical machine address (MAC) and a constantly-changing internet protocol (IP) in a LAN.
It works between Layer 2 and 3 of the OSI model, wherein the MAC address exists on Layer 2, while the IP address is on Layer 3.
SSL stands for Secure Sockets Layer, which is a technology that enables two (or more) systems/parties to securely communicate over the internet. It works in addition to HTTP at the presentation layer.
HTTPS, on the other hand, stands for Hypertext Transfer Protocol Secure. It combines SSL and HTTP, along with encryption to provide a hyper secure surfing experience. Its working includes the four upper layers of the OSI model.
This section of the blog consists of the most often-asked cyber security engineer interview questions or Cybersecurity interview questions. So, if this is the job title that aligns with your expertise, then follow through.
Encryption is the method that ensures data is rendered unreadable by everyone apart from those who have the secret key needed to decrypt the data. It is employed to ensure security of data over private connections.
Encoding is a method employed to ensure that the data is correctly formatted to be interpreted rightly by recipients and apps. Communication is made possible by transforming into an easy-to-read scheme.
Hashing methodology is used to help maintain data's integrity. A data hash refers to a string of data generated against the preserved information. This helps in comparing the original and transmitted data.
Perfect forward secrecy (PFS) is an encryption system that automatically and frequently alters the keys involved in encryption and decryption of information. It is an ongoing process that ensures minimal exposure of data in case of hacking.
WEP crack is a type of attack that exploits the vulnerabilities of the WEP (wireless equivalent privacy) protocol. This protocol was an early encryption method for securing wireless networks.
Network sniffing is basically a technique employed to evaluate the data packets that are delivered throughout the network. Specialized hardware and software is utilized to accomplish this task. Sniffing is employed for various purposes such as

Software development method used to write and test various versions of a software program simultaneously is called pipelining. It is quite similar to parallel processing, except that it works more in depth. As many programs run parallel to one another, weeks or months worth of work gets done in a few hours.
MAN or metropolitan area networks are engaged to connect multiple computers in different cities. With its large geographic scope, it may work as an internet service provider (ISP). These are less reliable, congested and difficult to establish and maintain.
Wi-Fi security means protecting networks and devices connected in a wireless environment. If there is no Wi-Fi security, then networking devices such as a router or a wireless access point can be easily accessed by anyone. This can be done with a mobile device or computer that is within the router's wireless signal range.
Stateful inspection in networking is a firewall technology. Also called dynamic packet filtering, it is used to monitor the condition of active connections, using this data to judge which network packets should be allowed through the firewall.
For those who already have experience in the field, these cyber security scenario based questions and answers will be extremely useful.
The attachment must not be downloaded. It could have malware, bugs or viruses, which may lead to corruption in the system. The link could also take on an unauthenticated third page, comprising safety. Also, it is quite easy to make a fake email id, which could also be the case here.
DoS and DDoS attacks differ from one another in the following ways.
PARAMETER | DoS Attack | DDoS Attack |
Source of Attack | It usually originates from a limited or single source that is under the attacker's control. | It employs a distributed network of compromised devices. This renders it more difficult to mitigate and identify the attack. |
Attack Method | The target network or system is flooded by a small group of sources or even a single source. High volume of requests or traffic is sent to overwhelm the resource. | Botnet is formed by compromised devices or computers via multiple sources. The target is bombarded collectively. |
Detection & Mitigation | It is comparatively easier to detect and mitigate this attack because the source is single/limited. | Since the source is varied, detecting and mitigating the attack becomes a challenge. |
