Top Cyber Security Interview Questions and Answers

Cyber??security awareness is defined as knowledge of an action taken to secure company information assets. It implies that they understand the dangers of cyber attacks, the possible impacts of cyber attacks on their companies, and the procedures needed to reduce risk and prevent cyber crime from penetrating their online workspace.

Cyber??security interview questions plus answers

1. What is the primary purpose of cyber security?

The primary purpose of cyber security is to protect data. The security sector offers a triangle of the three connected principles. Trio CIA is the name for this principle. One or more of these ideas has been violated when security violations are found. Confidentiality, integrity, and availability are three components of the CIA model. This part is a security paradigm that guides individuals through many aspects of IT security.

2. Distinguishing between threats, vulnerabilities, and risks.

Threats: Threats are all forms of danger that can potentially destroy or steal data, disrupt the operation, or cause damage in general. Malware, phishing, data violations, and even unethical employees are all examples of threats.Threat actors, individuals or groups with various backgrounds and motives, help express threats. Understanding threats is significant to develop effective mitigation and make informed Cyber Security decisions. The danger of intelligence is information about threats and threat actors.

Vulnerability: Vulnerability is defects in hardware, software, personnel, or procedures that actors can use threats to achieve their goals.Physical vulnerability, such as network equipment that is open to the public, software vulnerability, such as vulnerability buffer overflow in the browser, and even human vulnerability, such as employees vulnerable to phishing attacks, are all examples of vulnerabilities.

Risk: Probability of threats and consequences of vulnerability combined to form risk. The trouble is the possibility of a threat agent successfully exploiting vulnerabilities, which can be counted using the formula:

3. What is the XSS stand? How to prevent it?

XSS stands for cross-site scripting. It is a web security defect that allows attackers to manipulate how users interact with vulnerable applications. It will enable attackers to overcome the same-origin policy, which is intended to keep the website separate from each other. The disadvantages of cross-site scripts allow attackers to disguise themselves as victims users, carry out any action that users can do, and access any user data. If the victim user has unique access to the application, the attacker might take complete control of the functionality and application data.

4. What is a firewall?

Firewall functions as a barrier between LAN and the Internet. It allows personal resources to remain private while reducing security threats. It manages inbound and outbound network traffic.

Examples of firewalls between LAN and the Internet are displayed in the diagram below. The vulnerability point is the relationship between the two. At this point, network traffic can be filtered using hardware and software.

5. Set VPN.

The term VPN refers to virtual personal networks. It allows you to join your PC to a private network, create an encrypted connection that hides your IP address, allowing you to share data safely and access the web when maintaining your online identity.

Virtual personal networks, or VPN, are encrypted links between devices and networks through the internet. The encrypted connection helps in safe, sensitive data transmission. It protects against illegal tapping on traffic and allows users to work remotely. In company settings, VPN technology is usually used.

Conclusion:

Cyber Security is vital since it protects all types of data from theft and loss. Sensitive data, Personally identified information (PII), protected health information (PHI), personal information, intellectual property, data, and government and industrial information systems are all included in this category.
