Top Cybersecurity Interview Questions You Should be Prepared for

Here is a list of top frequently asked questions in interviews for freshers and experienced cybersecurity certification candidates.

1 What exactly is Cybersecurity?

Cybersecurity is a framework for protecting and securing anything vulnerable to hacks, strikes, or unauthorized access, mainly in terms of servers, computers, and programs. Its primary purpose is to protect against cyberattacks. 

2 Distinguish between a vulnerability, a threat, and a risk?

A vulnerability is a weakness in hardware, software, or procedures in order to achieve cyber-criminal goals.

Risks are the damages caused to the organization by exploiting vulnerabilities. In other words, Risk is a combination of the threat probability and the impact of a vulnerability. 

A threat is an activity, or you can say that a danger that can cause potential damage to the organization. 

3. Is there any difference between hashing and encryption?

Encryption is a two-way function which means what is encrypted can be decrypted with the proper key. On the other hand, hashing is a one-way function which means encrypted data can be converted back to original data.

4 Explain what Cryptography is?

It is a technique of protecting information and communications through the use of codes so that only intended parties or authorized users can read and process it. 

The three common types of cryptography are symmetric key, asymmetric key, and hash function. 

5 What is SSL?

SSL is a secure sockets layer, a protocol for web browsers and servers that allows encrypted connections on the internet. SSL encrypts data transmitted across the web, which means no authorized user can intercept or decrypt the transmitted data. 

6 What are some common types of cyberattacks an enterprise is likely to face?

  • Phishing
  • Brute-force attacks
  • DDoS attacks
  • Malware
  • Data leaks
  • Ransomware

7 Do you know what cross-site scripting is?

Cross-site scripting is a client-side code injection attack in which malicious scripts are injected into websites. This attack occurs when attackers allow an untrusted source to inject code into a legitimate web page or web application. 

8 Distinguish between HIDS and NIDS?

HIDS stands for Host IDS, and NIDS stands for Network IDS. Both IDS and NIDS are Intrusion Detection Systems that aim to protect from viruses, spyware, malware, and other malicious file types. The difference between the two is that HIDS monitors the traffic of a particular device and suspicious system activities and is installed only on certain intersection points, while NIDs are installed on every host machine and monitors traffic of all devices of the network.

9 Define Spyware.

Spyware is unwanted software or malware that intends to steal internet usage data and sensitive information, often without your knowledge.

10 How can you secure a web server?

  • Update ownership of the file.
  • Keep the web server updated.
  • Disable extra modules in the webserver.
  • Delete default scripts.
