Question 1

What is the primary function of a firewall?

Accepted Answer

Control network traffic

Answer

The primary function of a firewall is to monitor and control incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between a trusted internal network and untrusted external networks, such as the internet. By filtering traffic, firewalls prevent unauthorized access and protect internal systems from various cyber threats.

Question 2

Which device is used to segment a network into different subnetworks?

Accepted Answer

Router

Answer

A router is a networking device that forwards data packets between different computer networks. Its key function is to connect distinct networks and segment them into subnetworks, directing traffic efficiently and securely. Routers use IP addresses to determine the best path for data, enabling communication between various network segments and the internet.

Question 3

What is the purpose of a demilitarized zone (DMZ) in network security?

Accepted Answer

Isolate public-facing systems

Answer

A Demilitarized Zone (DMZ) is a perimeter network that isolates an organization's public-facing servers (like web servers, email servers, or DNS servers) from its internal private network. By placing these systems in a DMZ, an organization can provide external users with access to certain services while protecting its core internal network from direct external threats. This acts as a buffer zone, enhancing overall network security.

Question 4

Which protocol secures web communication?

Accepted Answer

HTTPS

Answer

HTTPS (Hypertext Transfer Protocol Secure) is the protocol used for secure communication over a computer network, widely used on the internet. It encrypts the data exchanged between a user's web browser and a website, protecting sensitive information like login credentials and payment details. This security is achieved through the use of Transport Layer Security (TLS).

Question 5

Which tool detects unauthorized access attempts?

Accepted Answer

Intrusion Detection System (IDS)

Answer

An Intrusion Detection System (IDS) is a security tool designed to monitor network or system activities for malicious activity or policy violations. It analyzes traffic and system logs for patterns that indicate unauthorized access attempts, such as port scans or malware signatures. Upon detecting a potential threat, an IDS typically alerts administrators, allowing for timely response.
