Cybersecurity FAQ

Question 1

What is the purpose of a VPN in cybersecurity?

Accepted Answer

A VPN (Virtual Private Network) enhances cybersecurity by encrypting internet connections, hiding IP addresses, and securing data transmissions. It protects users' privacy, prevents tracking, and allows safe access to sensitive resources over public or unsecured networks.

Question 2

What does "zero-day exploit" mean?

Accepted Answer

A zero-day exploit refers to a security vulnerability in software that is unknown to the vendor. Hackers exploit it before a fix is available, making it extremely dangerous and difficult to defend against immediately.

Question 3

What is ransomware, and how does it work?

Accepted Answer

Ransomware is malicious software that encrypts a victim's files, locking access. Attackers demand payment—often in cryptocurrency—for a decryption key. It typically spreads through phishing, malicious links, or vulnerable systems without proper security measures.

Question 4

What is a firewall, and how does it protect a network?

Accepted Answer

A firewall is a security system that monitors and controls incoming and outgoing network traffic. It acts as a barrier between trusted and untrusted networks, blocking unauthorized access while allowing safe data communication to pass through.

Question 5

What is malware, and how can it infect a system?

Accepted Answer

Cybery the digital world by delivering innovative security solutions & promoting cybersecurity awareness. To create a cyber-secure environm-ent where businesses can thrive without fear of digital threats is everywhere.

Question 6

What is social engineering in cybersecurity?

Accepted Answer

Social engineering is a manipulation technique where attackers trick individuals into revealing confidential information or performing actions that compromise security. It often involves deception through emails, phone calls, or messages posing as trustworthy sources to gain access.

Question 7

Encryption vs Decryption: What's the Difference?

Accepted Answer

Encryption is the process of converting readable data into coded form to prevent unauthorized access. Decryption is the reverse—transforming that coded data back into its original, readable form using a key or password for access.

Question 8

What is a DDoS attack?

Accepted Answer

A DDoS (Distributed Denial of Service) attack floods a network, server, or website with overwhelming traffic from multiple sources, causing it to slow down or crash. It disrupts normal operations and denies access to legitimate users.
