Cyber Security Interview Questions & Answers

1) What is Cyber Security?

Cyber security is the process of protection of hardware, software and data from the hackers. The primary purpose of implementing these cyber security techniques is to protect against different cyberattacks such as changing, accessing or destroying sensitive data.

2) What are The Fundamental Elements of Cyber Security?

Following are the main elements of cyber security:

  • Information security
  • End-user education
  • Operational security
  • Application security
  • Network security
  • Business continuity planning

3) What are The Main Advantages of Cyber Security?

  • Protects the business against unauthorized access including ransomware, social engineering, malware and phishing.
  • Protects end-users and improve the business continuity management
  • Improves stakeholder confidence
  • Provide adequate protection for both data as well as networks
  • Increase recovery time after any breach

4) What Do You Means By Cryptography?

Cryptography is the technique which is used to protect the confidential information from third parties called adversaries. It allows both sender and receiver of any message to read its details.

5) What is The Main Difference between IDS and IPS?

As the name indicates, IDS (Intrusion Detection System) detects the intrusions and an administrator prevent the intrusion carefully. Whereas in the IPS (Intrusion Prevention System), the system finds the intrusion and prevent it for better protection.

6) Explain The CIA Model?

CIA (Confidentiality, Integrity, and Availability) is a common model that is used to develop a security policy. It consists of the following concepts:

  • Confidentiality: Ensure the confidential and private data is accessed only by the authorized users
  • Integrity: It means the information is in the right format
  • Availability: Ensure the data and other required resources are available to those users who need them

7) Define The Firewall?

In simple words, the firewall is a network security device which is mainly designed to monitor incoming and outgoing traffic and blocks data based on the security rules.
