1. What is Cybersecurity?

This is what is involved in cybersecurity. Even its definition is making sure that a password exists to block any damage or attack to computer systems, networks, and data from unauthorized persons. This will also ensure that the confidentiality, integrity, and availability of information are provided in the simplest form.

2. What is CIA Trigraph?

  • The model is the most fundamental in designing and evaluating security systems.

  • Only those who have authorization can access the information.

  • That information is accurate and non-changing while in the keeping of the entity.

  • The information and systems are always available.

3. What is the difference between Threat, Vulnerability, and Risk?

  • Threat- anything that could harm a system, including malware, hackers, etc.

  • Vulnerability-a flaw or weakness that opens a threat to enter into a system.

  • Risk- possible loss or damage resulting from such a threat exploiting that vulnerability.

4. What is the difference between Symmetric Encryption and Asymmetric Encryption?

Symmetric encryptions encrypt data with the same key for both encryption and decryption, but asymmetric encryption uses a pair of keys, a public and a private.

AES is an example of symmetric encryption, while RSA is one for asymmetric encryption.

5. What is a Firewall?

A firewall is a security tool that filters incoming and outgoing network traffic based on predefined Rules. It lies between an organization's secure internal networks and untrusted external networks, where it protects them from potential threats.

6. What is a VPN?

A virtual private network (VPN) encrypts your internet connection and hides your IP address. It protects data from hackers, particularly while being connected to public Wi-Fi, and allows remote employees to safely access company networks.

7. What are the common types of Cyber attacks?

The major types of cyberattacks are as follows:

  1. Phishing

  2. Ransomware

  3. Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) attacks

  4. SQL Injection

  5. Cross-Site Scripting (XSS)

  6. Malware infections

  7. Man-in-the-Middle attacks

8. What is the Difference Between IDS and IPS?

An Intrusion Detection System is a device that detects a threat by keeping an eye on the actions of network traffic. They alert the administrator of an organization predominantly.

An Intrusion Prevention System does that as well as controlling the blocking of threat events and/or holding that threat captive.

9. What is Two-Factor Authentication (2FA)?

Two-Factor Authentication (2FA) is a system where an individual is required to provide two forms of security to access a system, for example, a password, an OTP, or a fingerprint. It is used to mitigate unauthorized access when passwords are compromised.

10. What is Social Engineering?

Social engineering is a manipulation technique used by an intruder to deceive individuals into revealing personal private information. This includes phishing emails, bogus support calls, and capturing users with free downloads or gifts.

11. What is a vulnerability in a zero-day?

A zero-day vulnerability occurs when a software flaw is detected and exploited by hackers before it can be fixed or patched by the software company. Hence, the term zero day is used because a developer has zero days after the problem is known to address it. 

12. What is the OSI Model, and why is it really important in Cybersecurity? 

The seven layers through which data moves through a network have been described by the OSI (Open Systems Interconnection) Model. This depicts encryption, firewalls, and authentication measures in different OSI layers. 

13. What is penetration testing?

Pen testing (or ethical hacking) is the exercise of attempting to breach a system's defenses by very high-level cyber attacks. Those who are in charge of Security will later discover these vulnerability issues and repair them before bad guys get to them. 

14. What are Black Hat, White Hat, and Grey Hat Hackers? 

  • Black Hat hackers are the ones who maliciously hack into systems for personal gain or to cause damage.

  • White Hat hackers are ethical hackers who will find and fix vulnerabilities to benefit to strengthen security. 

  • Grey Hat hackers infringe the rules but are not destructive about it. 

15. What are the Best Practices for Cybersecurity? 

Some best practices should be followed in any organization:

  • Keep the software in every field up to date with the latest patches. 

  • Always use strong and unique passwords. 

  • Enable multi-factor authentication. 

  • Back up important data frequently. 

  • Educate your employees on recognizing phishing and other sorts of scams. 

  • Access to sensitive data should be limited only to those who need it.
